一、 Irecycleview
Irecycleview是自定义的recyclerview，支持上拉刷新、下拉加载更多结合
How to use 使用1
Step 1. 引用Irecycleview包
- include ':app', ':library:irecyclerview' //settings.gradle
- compile project(':library:irecyclerview')//build.gradle(Module:app)
Step 2.在布局文件中引用IRecyclerView
<com.aspsine.irecyclerview.IRecyclerView
android:id="@+id/population_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
app:loadMoreEnabled="true"
app:refreshEnabled="true"
app:refreshHeaderLayout="@layout/layout_irecyclerview_refresh_header" />：
Step 3. 新建Viewholder Item项的布局文件（呈现数据的样式）
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardBackgroundColor="@color/gray6"
app:cardCornerRadius="6dp"
app:cardElevation="2dp"
app:cardPreventCornerOverlap="true"
app:cardUseCompatPadding="true"
android:clickable="true"
android:foreground="?android:attr/selectableItemBackground"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:id="@+id/family_cb_control"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:visibility="gone">
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp">
<ImageView
android:id="@+id/familyIco"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@mipmap/ic_familyheader" />
</LinearLayout>
<LinearLayout
android:id="@+id/family_detail"
style="@style/listbox_linearLayout">
<TextView
android:id="@+id/familyName"
style="@style/listbox_linearLayout_name"
android:text="阿不来提 奥斯曼" />
<TextView
android:id="@+id/familyIDcard"
style="@style/listbox_linearLayout_id"
android:text="650212099012032210" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="@+id/locateIcon"
>
<ImageButton
android:id="@+id/locateBtn"
style="@style/listbox_linearLayout_icon_location" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginRight="1dp"
>
<ImageButton android:id="@+id/detailBtn"
style="@style/listbox_linearLayout_icon_detail" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
</android.support.v7.widget.CardView>
Step 4. 在使用Irecycleview 的Activity中使用：
- 初始化：
mRecyclerView=(IRecyclerView)findViewById(R.id.population_recycler_view);
LinearLayoutManager pLayoutManager= new LinearLayoutManager(this);
mLayoutManager=pLayoutManager;
// 设置布局管理器
mRecyclerView.setLayoutManager(mLayoutManager);
// 设置adapter
mAdapter = new search_population_adapter(this, populationPresenterImpl);
//加载数据动画
mAdapter.openLoadAnimation(new ScaleInAnimation());
mRecyclerView.setAdapter(mAdapter);
//监听recyclerview滑动
//上拉刷新
mRecyclerView.setOnRefreshListener(new OnRefreshListener() {
@Override
public void onRefresh() {
mAdapter.getPageBean().setRefresh(true);
loadData();//获取数据
}
});
//下拉加载更多
mRecyclerView.setOnLoadMoreListener(new OnLoadMoreListener() {
@Override
public void onLoadMore(View loadMoreView) {
mRecyclerView.setLoadMoreStatus(LoadMoreFooterView.Status.LOADING);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mAdapter.getPageBean().setRefresh(false);
loadData();;//获取数据
}
}, 1000);
}
});
//其中PageBean()中封装了与分页相关的数据（page总页数 rows 每页的行数
//totalCount 总记录数 //totalPage 总页数 //refresh 标志，是否刷新）
- 适配数据
public void GetHouseList(List<HouseItem> houseItemsList,PageBean pageBean) {
if (mAdapter.getPageBean().isRefresh()) {
mRecyclerView.setRefreshing(false);
mAdapter.reset(houseItemsList);
} else {
if(pageBean.getPage()==1){
mAdapter.reset(houseItemsList);
}else{
mAdapter.addAll(houseItemsList);
mRecyclerView.setLoadMoreStatus(LoadMoreFooterView.Status.GONE);
}
}
}
Step 5. 新建适配器adapter 让其继承自BaseReclyerViewAdapter<T>,其中T为我们要呈现数据的数据类型（结构）
public class search_family_adapter extends BaseReclyerViewAdapter<FamilyItem> {
public static final int ITEM_VIEW_TYPE_DEFAULT = 0;
public static final int ITEM_VIEW_TYPE_IMAGE = 1;
public static final int ITEM_VIEW_TYPE_URL = 2;
private Context mContext;
private FamilyPresenter mPresenter;
public search_family_adapter(Context context, FamilyPresenter mPresenter) {
super(context);
this.mContext=context;
this.mPresenter=mPresenter;
}
@Override
public int getItemViewType(int position) {
return getData().get(position).getType();
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return search_Family_ViewHolder.create(mContext,viewType);
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
super.onBindViewHolder(holder, position);
if(holder instanceof search_Family_ViewHolder) {
((search_Family_ViewHolder) holder).setData(mPresenter, get(position), position);
}
}
@Override
public int getItemCount() {
return getData().size();
}
}
Step 6. 新建适配器adapter 新建viewHolder(让数据的每一项适配viewItem)，让其继承自RecyclerView.ViewHolder
public class search_Family_ViewHolder extends RecyclerView.ViewHolder {
private Context mContext;
private FamilyPresenter mPresenter;
private FamilyItem familyItem;
private int position;
private View itemView;
private int type;
public ImageView familyIcoIv;
public TextView familyNameTv;
public TextView familyIDcardTv;
public ImageView deleteBtn;
public ImageView detailBtn;
public LinearLayout family_detail;
public LinearLayout locateIcon;
public ImageView locateBtn;
public static search_Family_ViewHolder create(Context context, int type) {
search_Family_ViewHolder imageViewHolder = new search_Family_ViewHolder(LayoutInflater.from(context).inflate(R.layout.item_search_family, null), context, type);
return imageViewHolder;
}
public search_Family_ViewHolder(View itemView, final Context context, int type) {
super(itemView);
this.itemView=itemView;
this.type=type;
this.mContext = context;
initView();
}
//在Item项中通过Id查找到对应控件
private void initView()
familyIcoIv = (ImageView) itemView.findViewById(R.id.familyIco);
familyNameTv = (TextView) itemView.findViewById(R.id.familyName);
familyIDcardTv = (TextView) itemView.findViewById(R.id.familyIDcard);
}
//循环每一项数据，匹配到对应的控件，显示出来
public void setData(FamilyPresenter mPresenter2, FamilyItem familyItem2, final int position2) {
if(mPresenter2==null|| familyItem2 ==null){
return;
}
this.familyItem = familyItem2;
this.mPresenter=mPresenter2;
this.position=position2;
//头像
if(familyItem.getPhoto()!=null){
familyIcoIv.setImageResource(familyItem.getFamilyheader);
familyNameTv.setText(familyItem.getPopulationame());
familyIDcardTv.setText(familyItem.getIdentitynumber());
//处理Item项或者Item项中控件的的单击等事件
detailBtn = (ImageView) itemView.findViewById(R.id.detailBtn);
detailBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//详情
if (mPresenter != null) {
mPresenter.detailFamily(familyItem.getId(), position);
}
}
});
family_detail = (LinearLayout) itemView.findViewById(R.id.family_detail);
family_detail.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//详情
if (mPresenter != null) {
mPresenter.detailFamily(familyItem.getId(), position);
}
}
});
}
}
How to use 2 （Viewholder通用）
Step 1. 在布局文件中引用IRecyclerView：（和上同）
Step 2. 新建Item项的布局文件（和上同）
Step 3. 在要使用Irecycleview 的Activity中使用：
- 初始化：
mRecyclerView = (IRecyclerView) findViewById(R.id.family_recycler_view);
LinearLayoutManager pLayoutManager= new LinearLayoutManager(this);
mLayoutManager=pLayoutManager;
// 设置布局管理器
mRecyclerView.setLayoutManager(mLayoutManager);
// 设置adapter
//mAdapter = new search_family_adapter(this, familyPresenterImpl);
mAdapter = new search_family_adapter(this,R.layout.item_search_family);
mAdapter.openLoadAnimation(new ScaleInAnimation());
mRecyclerView.setAdapter(mAdapter);
//监听recyclerview滑动
setViewTreeObserver();
//上拉刷新
mRecyclerView.setOnRefreshListener(new OnRefreshListener() {
@Override
public void onRefresh() {
mAdapter.getPageBean().setRefresh(true);
loadData();
}
});
//下拉加载更多
mRecyclerView.setOnLoadMoreListener(new OnLoadMoreListener() {
@Override
public void onLoadMore(View loadMoreView) {
mRecyclerView.setLoadMoreStatus(LoadMoreFooterView.Status.LOADING);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mAdapter.getPageBean().setRefresh(false);
loadData();
}
}, 1000);
}
});
- 适配数据（和上同）：
public void GetFamilyList(List<FamilyItem> playBeanListHolderList, PageBean pageBean) {
if (mAdapter.getPageBean().isRefresh()) {
mRecyclerView.setRefreshing(false);
mAdapter.replaceAll(playBeanListHolderList);
} else {
if(pageBean.getPage()==1){
mAdapter.replaceAll(playBeanListHolderList);
}else{
mAdapter.addAll(playBeanListHolderList);
mRecyclerView.setLoadMoreStatus(LoadMoreFooterView.Status.GONE);
}
}
//判断是否还可以加载更多
if (pageBean.getTotalPage() <= pageBean.getPage()) {
mRecyclerView.setLoadMoreStatus(LoadMoreFooterView.Status.THE_END);
}
mAdapter.setOnItemClickListener(new search_family_adapter.OnItemClickListener() {
@Override
public void onItemClick(View view, BigDecimal id,int position) {
//...
}
});
mAdapter.setOnLocateClickListener(new search_family_adapter.OnLocateBtnClickListener() {
@Override
public void onLocateBtnClick(View view,String qrcode, int position) {
//...
}
});
}
Step 4. 新建适配器adapter让其继承CommonRecycleViewAdapter<T>
public class search_family_adapter extends CommonRecycleViewAdapter<FamilyItem> {
public search_family_adapter(Context context, int layoutId) {
super(context, layoutId);
}
@Override
public void convert(ViewHolderHelper helper, FamilyItem familyItem) {
//头像
if(familyItem.getPhoto()!=null){
String URL= PictureURLService.getFamiyPictureURL(familyItem.getPhoto());
helper.setBigImageUrl(R.id.familyIco,URL);
}else {
helper.setImageResource(R.id.familyIco,R.mipmap.ic_familyheader);
}
helper.setText(R.id.familyName,familyItem.getPopulationame());
helper.setText(R.id.familyIDcard,familyItem.getIdentitynumber());
handleOnClick(helper,familyItem);
LocatedOnClick(helper,familyItem);
}
private OnItemClickListener mOnItemClickListener;
public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
mOnItemClickListener = onItemClickListener;
}
public interface OnItemClickListener {
void onItemClick(View view, BigDecimal id, int position);
}
private OnLocateBtnClickListener mBtnLocateClickListener;
public void setOnLocateClickListener(OnLocateBtnClickListener onLocateClickListener) {
mBtnLocateClickListener = onLocateClickListener;
}
public interface OnLocateBtnClickListener {
void onLocateBtnClick(View view,String qrcode, int position);
}
private void handleOnClick(final ViewHolderHelper helper,final FamilyItem familyItem) {
if (mOnItemClickListener != null) {
helper.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mOnItemClickListener.onItemClick(v,familyItem.getId(), helper.getLayoutPosition());
}
});
helper.setOnClickListener(R.id.detailBtn, new View.OnClickListener() {
@Override
public void onClick(View v) {
mOnItemClickListener.onItemClick(v,familyItem.getId(), helper.getLayoutPosition());
}
});
}
}
private void LocatedOnClick(final ViewHolderHelper helper,final FamilyItem familyItem) {
if (mBtnLocateClickListener != null) {
helper.setOnClickListener(R.id.locateBtn, new View.OnClickListener() {
@Override
public void onClick(View v) {
mBtnLocateClickListener.onLocateBtnClick(v,familyItem.getQrcode(), helper.getLayoutPosition());
}
});
helper.setOnClickListener(R.id.locateIcon, new View.OnClickListener() {
@Override
public void onClick(View v) {
mBtnLocateClickListener.onLocateBtnClick(v,familyItem.getQrcode(), helper.getLayoutPosition());
}
});
}
}
}
Step6. ViewHold使用通用ViewHolderHelper
二、 多图片选择器ImagePicker库
完全仿微信的图片选择，并且提供了多种图片加载接口，选择图片后可以旋转，可以裁剪成矩形
How to use
Step 1. 在自己项目中添加本项目依赖
compile 'com.lqr.imagepicker:library:1.0.0'
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'
Step2. 实现ImageLoader接口，实现图片加载策略
public class UILImageLoader implements com.lqr.imagepicker.loader.ImageLoader {
@Override
public void displayImage(Activity activity, String path, ImageView imageView, int width, int height) {
ImageSize size = new ImageSize(width, height);
com.nostra13.universalimageloader.core.ImageLoader.getInstance().displayImage(Uri.parse("file://" + path).toString(), imageView, size);
}
@Override
public void clearMemoryCache() {
}
}
Step3. Application中初始化
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
initUniversalImageLoader();
initImagePicker();
}
private void initUniversalImageLoader() {
//初始化ImageLoader
ImageLoader.getInstance().init(
ImageLoaderConfiguration.createDefault(getApplicationContext()));
}
/**
* 初始化仿微信控件ImagePicker
*/
private void initImagePicker() {
ImagePicker imagePicker = ImagePicker.getInstance();
imagePicker.setImageLoader(new UILImageLoader()); //设置图片加载器
imagePicker.setShowCamera(true); //显示拍照按钮
imagePicker.setCrop(true); //允许裁剪（单选才有效）
imagePicker.setSaveRectangle(true); //是否按矩形区域保存
imagePicker.setSelectLimit(9); //选中数量限制
imagePicker.setStyle(CropImageView.Style.RECTANGLE); //裁剪框的形状
imagePicker.setFocusWidth(800); //裁剪框的宽度。单位像素（圆形自动取宽高最小值）
imagePicker.setFocusHeight(800); //裁剪框的高度。单位像素（圆形自动取宽高最小值）
imagePicker.setOutPutX(1000);//保存文件的宽度。单位像素
imagePicker.setOutPutY(1000);//保存文件的高度。单位像素
}
}
Step4. 图片选择界面代码：
public static final int IMAGE_PICKER = 100;
Intent intent = new Intent(this, ImageGridActivity.class);
startActivityForResult(intent, IMAGE_PICKER);
5、获取所选图片信息：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == ImagePicker.RESULT_CODE_ITEMS) {//返回多张照片
if (data != null) {
boolean isOrig = data.getBooleanExtra(ImagePreviewActivity.ISORIGIN, false);
ArrayList<ImageItem> images = (ArrayList<ImageItem>) data.getSerializableExtra(ImagePicker.EXTRA_RESULT_ITEMS);
}
}
}
}
三、 扫一扫：简单的ZXing使用
ZXing是Google提供的条形码、二维码等的生成、解析的库
How to use
Step1. 添加本项目依赖
compile 'com.google.zxing:core:3.2.1'
compile 'cn.bingoogolapple:bga-qrcodecore:1.1.7@aar'
compile 'cn.bingoogolapple:bga-zxing:1.1.7@aar'
Step2. 创建 Scan.xml布局文件,这个就是扫描二维码的界面
android:id="@+id/zxingview"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:qrcv_animTime="1000"
app:qrcv_barCodeTipText="将条码放入框内，即可自动扫描"
app:qrcv_barcodeRectHeight="140dp"
app:qrcv_borderColor="@android:color/white"
app:qrcv_borderSize="0.5dp"
app:qrcv_cornerColor="@color/green3"
app:qrcv_cornerLength="20dp"
app:qrcv_cornerSize="3dp"
app:qrcv_isBarcode="false"
app:qrcv_isCenterVertical="false"
app:qrcv_isOnlyDecodeScanBoxArea="false"
app:qrcv_isScanLineReverse="true"
app:qrcv_isShowDefaultGridScanLineDrawable="false"
app:qrcv_isShowDefaultScanLineDrawable="true"
app:qrcv_isShowTipBackground="true"
app:qrcv_isShowTipTextAsSingleLine="false"
app:qrcv_isTipTextBelowRect="true"
app:qrcv_maskColor="#33FFFFFF"
app:qrcv_qrCodeTipText="将二维码/条码放入框内，即可自动扫描"
app:qrcv_rectWidth="200dp"
app:qrcv_scanLineColor="@color/green1"
app:qrcv_scanLineMargin="0dp"
app:qrcv_scanLineSize="0.5dp"
app:qrcv_tipTextColor="@android:color/white"
app:qrcv_tipTextSize="12sp"
app:qrcv_toolbarHeight="56dp"
app:qrcv_topOffset="90dp"/>
Step3. 扫描二维码的Activity页面
public class ScanActivity extends BaseActivity implements QRCodeView.Delegate {
public final static int result_Code=99;
private FrameLayout mView;
private PopupWindow mPopupWindow;
public static final int IMAGE_PICKER = 100;
ZXingView mZxingview;
public void initListener() {
mZxingview.setDelegate(this);}
@Override
protected void onStart() {
setContentView(R.layout.activity_scan);
super.onStart();
mZxingview=(ZXingView) findViewById(R.id.zxingview);
mZxingview.setDelegate(this);
mZxingview.startCamera();
mZxingview.startSpot();
mLlFanyi.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(ScanActivity.this, ImageGridActivity.class);
startActivityForResult(intent, IMAGE_PICKER);
}});
}
@Override
protected void onStop() {
super.onStop();
mZxingview.stopCamera();
}
@Override
protected void onDestroy() {
super.onDestroy();
mZxingview.onDestroy();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.menu_more, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
finish();
break;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onScanQRCodeSuccess(String result) {
handleResult(result);
}
private void vibrate() {
Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
vibrator.vibrate(200);
}
public void onScanQRCodeOpenCameraError() {
showToast("打开相机出错");
}
private void handleResult(String result) {
vibrate();
Intent intent =new Intent();
//设置返回信息
intent.putExtra("qrcode", result);
//设置返回码和通信使者
setResult(result_Code,intent);
//完成，关闭当前页面并返回
finish();
}
}
四、 CityPickerView 实现省市区三级联动选择
需要在地址选择中实现省市区三级联动，方便用户快速的填写地址
How to use
Step1. 添加本项目依赖
compile 'liji.library.dev:citypickerview:0.7.0'
Step2. Activity使用
//Texview的点击事件
public void chooseArea(View view) {
//判断输入法的隐藏状态
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isActive()) {
imm.hideSoftInputFromWindow(view.getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
selectAddress();//调用CityPicker选取区域
}
}
private void selectAddress() {
CityPicker cityPicker = new CityPicker.Builder(NewAddressActivity.this)
.textSize(14)
.title("地址选择")
.titleBackgroundColor("#FFFFFF")
.titleTextColor("#696969")
.confirTextColor("#696969")
.cancelTextColor("#696969")
.province("新疆省")
.city("阿克苏市")
.district("温宿县")
.textColor(Color.parseColor("#000000"))
.provinceCyclic(true)
.cityCyclic(false)
.districtCyclic(false)
.visibleItemsCount(7)
.itemPadding(10)
.onlyShowProvinceAndCity(false)
.build();
cityPicker.show();
//监听方法，获取选择结果
cityPicker.setOnCityItemClickListener(new CityPicker.OnCityItemClickListener() {
@Override
public void onSelected(String... citySelected) {
//省份
String province = citySelected[0];
//城市
String city = citySelected[1];
//区县（如果设定了两级联动，那么该项返回空）
String district = citySelected[2];
//邮编
String code = citySelected[3];
//为TextView赋值
new_address_area.setText(province.trim() + "-" + city.trim() + "-" + district.trim());
}
});
}
五、 AlertDialod
弹出确定删除（一般删除数据时，我们一般都要弹出确定删除弹出框，以避免数据的误删除）
How to use
Step1. 新建MDAlertDialog

() * builder.getHeight()));
mDialog.setContentView(mDialogView);
Window dialogWindow = mDialog.getWindow();
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
lp.width = (int) (ScreenSizeUtils.getInstance(mContext).getScreenWidth() * builder.getWidth());
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
lp.gravity = Gravity.CENTER;
dialogWindow.setAttributes(lp);
initDialog();
}
private void initDialog() {

.setTitleVisible(true)
.setTitleText("提示")
.setTitleTextColor(R.color.black_light)
.setContentText("确定删除该条记录吗？")
.setContentTextColor(R.color.black_light)
.setLeftButtonText("不删除")
.setLeftButtonTextColor(R.color.black_light)
.setRightButtonText("删除")
.setRightButtonTextColor(R.color.gray)
.setTitleTextSize(16)
.setContentTextSize(14)
.setButtonTextSize(14)
.setOnclickListener(new DialogOnClickListener() {
@Override
public void clickLeftButton(View view) {
mdAlertDialog.dismiss();
}
@Override
public void clickRightButton(View view) {
mdAlertDialog.dismiss();
//mPresenterView.startProgressDialog();
Subscription subscription = mPopManageInteractor.deleteById(new IGetDataDelegate<String>() {
@Override
public void getDataSuccess(String deleteflag) {
mPresenterView.deletePopulationItem(deleteflag,position);
}
@Override
public void getDataError(String errmsg) {
mPresenterView.deletePopulationItem(errmsg,position);
}
},id);
mSubscriptions.add(subscription);
}
})
.build();
mdAlertDialog.show();
}

八、语音识别工具 ----[科大讯飞] 例： 参考KEDAXUNFEI项目 官网
SVN:https://220.171.2.106:8800/svn/KEDAXUNFEI/
How to use
Step1. gradle
- 在官网申请服务获得Appid。（已获得Appid:5966ff6e）
- 右键单击main目录，选择New>Folder>Assets Folder ,将ifytek文件夹粘入该文件夹下
- 右键单击main目录，选择New>Directory>jinLibs,将armeabi和armeabi-v7a放入该文件夹下
- 右键单击app目录，选择New>Directory>libs,将Msc.jar放入该文件夹下,build.gradle的dependencies加入 compile files('libs/Msc.jar')

SpeechUtility.createUtility(MainActivity.this, SpeechConstant.APPID + "=578f1af7");
Step4. 单击button后，启动对话框开始录音
private RecognizerDialog iatDialog;
//etText为语音识别后的文字输出文本框
EditText etText = (EditText) findViewById(R.id.main_et_text);
//btnStartSpeak为单击后启动语音识别的按钮
Button btnStartSpeak== (Button) findViewById(R.id.main_btn_startSpeak);
//触犯录音按钮后执行单击事件
btnStartSpeak.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//在单击button后，启动对话框开始录音
iatDialog = new RecognizerDialog(MainActivity.this, mInitListener);
iatDialog.setListener(new RecognizerDialogListener() {
String resultJson = "[";//放置在外边做类的变量则报错，会造成json格式不对（？）
@Override
public void onResult(RecognizerResult recognizerResult, boolean isLast) {
System.out.println("----------------- onResult -----------------");
if (!isLast) {
resultJson += recognizerResult.getResultString() + ",";}
else { resultJson += recognizerResult.getResultString() + "]";}
if (isLast) {
//解析语音识别后返回的json格式的结果
Gson gson = new Gson();
List<DictationResult> resultList = gson.fromJson(resultJson,
new TypeToken<List<DictationResult>>() {}.getType());
String result = "";
for (int i = 0; i < resultList.size() - 1; i++) {
result += resultList.get(i).toString();
}
etText.setText(result);
//获取焦点
etText.requestFocus();
//将光标定位到文字最后，以便修改
etText.setSelection(result.length());
}
}
@Override
public void onError(SpeechError speechError) {
//自动生成的方法存根
speechError.getPlainDescription(true);
}
});
//开始听写，需将sdk中的assets文件下的文件夹拷入项目的assets文件夹下（没有的话自己新建）
iatDialog.show();
}
private InitListener mInitListener = new InitListener() {
@Override
public void onInit(int code) {
Log.d(TAG, "SpeechRecognizer init() code = " + code);
if (code != ErrorCode.SUCCESS) {
Toast.makeText(MainActivity.this, "初始化失败，错误码：" + code, Toast.LENGTH_SHORT).show();
}
}
};
九、 基础知识
文件按表单形式上传(Retrofit)
Step1. Retrofit APIService接口定义 方法
@Multipart
@POST("upload.action?commandId=PopulationManage&command=savemobile")
Observable<String> savepop(@Query("population") String pop ,@Part MultipartBody.Part file);
Step2. 调用Retrofit方法上传文件
File file_img = new File(images.get(0).path);
RequestBody requestFile = RequestBody.create(MediaType.parse("application/otcet-stream"), file_img);
MultipartBody.Part body body = MultipartBody.Part.createFormData("aFile", file_img.getName(), requestFile);
return RetrofitManager.getInstance()
.getLiveAPIService().savepop(population,body).
compose(TransformUtils.<String >defaultSchedulers())
.subscribe(new MSubscriber<String>() {
@Override
public void onError(Throwable e)
{
super.onError(e);
}
public void onNext(final String msg) {
try {
LogUtil.e("保存成功");
delegate.getDataSuccess(msg);
} catch (Exception e) {
LogUtil.e("数据有误" +e.toString());
}
}
})
获取Activity返回的参数
十、 TDevice net.oschina.app.util.TDevice(Oschina项目)
- 安装APK installAPK()
- 获取当前版本名称 getVersionName()
- 获取当前版本号 getVersionCode()
- 打开手机端的应用市场 openAppInMarket()
- 隐藏软键盘 hideSoftKeyboard()
- 显示软键盘 showSoftKeyboard()
- 判断是否为平板电脑 isTablet()
- 判断WIFI是否打开 isWifiOpen()
- 判断是否有WebView hasWebView()
十一、 Easypermissions(Oschina项目)
- 简书 Android开源项目-Easypermissions
-
Android权限最佳实践和代码实例分析
Easypermissions简化了Android M的运行时权限的申请、结果处理、判断等步骤.
How to use
Step1. Gradle
dependencies {
compile 'pub.devrel:easypermissions:0.1.9'
}
Step2. 检查权限
String[] perms = {Manifest.permission.CAMERA, Manifest.permission.CHANGE_WIFI_STATE};
if (EasyPermissions.hasPermissions(this, perms)) {
} else {
}
Step3. 申请权限
EasyPermissions.requestPermissions(this, "拍照需要摄像头权限",
RC_CAMERA_AND_WIFI, perms);
Step4. 实现EasyPermissions.PermissionCallbacks接口，直接处理权限是否成功申请
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Forward results to EasyPermissions
EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}
//成功
@Override
public void onPermissionsGranted(int requestCode, List<String> list) {
// Some permissions have been granted
// ...
}
//失败
@Override
public void onPermissionsDenied(int requestCode, List<String> list) {
// Some permissions have been denied
// ...
}
十二、 版本检查更新 ----MainActivity的checkUpdate()方法(Oschina项目)
How to use
Step1. 引用
- CheckUpdateManager---net\oschina\app\improve\main\update\CheckUpdateManager
- DownloadService ---net\oschina\app\improve\main\update\DownloadService
Step2. 调用checkUpdateManger.checkUpdate()的方法，当获取的版本号大于当前版本时,调用RequestPermissions接口的call方法
Step3. checkUpdateManger.checkUpdate()需要请求服务以获取最新版本信息，需要根据具体情况修改。DownloadService也要做适当修改
@Override
protected void initData() {
super.initData();
checkUpdate();
}
private void checkUpdate() {
if (!AppContext.get(AppConfig.KEY_CHECK_UPDATE, true)) {
return;
}
CheckUpdateManager manager = new CheckUpdateManager(this, false);
manager.setCaller(this);
manager.checkUpdate();
}
Step4. 实现RequestPermissions接口（调用checkUpdateManger定义了该接口）。在该方法中调用DownloadService.startService开始下载最新版本的APP
@Override
public void call(Version version) {
this.mVersion = version;
requestExternalStorage();//检查app是否有读写磁盘权限
}
@AfterPermissionGranted(RC_EXTERNAL_STORAGE)
public void requestExternalStorage() {
if (EasyPermissions.hasPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
DownloadService.startService(this, mVersion.getDownloadUrl());
} else {
EasyPermissions.requestPermissions(this, "", RC_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE);
}
}
