前言
相信用过工具类的各位仁兄都觉得工具类好用，小弟不才，今天斗胆拿出自己感觉比较顺手的工具类。
1、Activity控制类
public class ActivityCollector{
//activity集合
public static List<Activity> mActList = new ArrayList<Activity>();
/**
* 添加Activity
*
* @param activity
*/
public static void addActivity(Activity activity){
mActList.add.add(activity);
}
}
/**
* 移除Activity
*/
public static void removeActivity(Activity activity) {
mActList.remove(activity);
}
/**
* 退出
*/
public static void finishAll() {
for (Activity activity : mActList) {
if (!activity.isFinishing()) {
activity.finish();
}
}
}
}
2、应用市场管理类
public class MarketUtils {
// 360手机助手
public static final String MARKET = "com.qihoo.appstore";
// 淘宝手机助手
public static final String MARKET_TAOBAO = "com.taobao.appcenter";
// 应用宝
public static final String MARKET_QQDOWNLOADER = "com.tencent.Android.qqdownloader";
// 安卓市场
public static final String MARKET_HIAPK = "com.hiapk.marketpho";
// 安智市场
public static final String MARKET_GOAPK = "cn.goapk.market";
// 包名
public static final String APP_PACKAGE_NAME = "com.*.*";
public MarketUtils() {
throw new AssertionError();
}
/**
* 跳转到应用市场
*
* @param appPkg
* ：上传到应用市场上app的包名,不是本项目的包名
* @param marketPkg
* ：应用市场的包名
*/
public static void goToMarket(Context context, String packageName) {
Uri uri = Uri.parse("market://details?id=" + packageName);
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
try {
context.startActivity(goToMarket);
} catch (ActivityNotFoundException e) {
}
}
/**
* 启动App
*
* @param context
*/
public static void launchapp(Context context) {
// 判断是否安装过App，否则去市场下载
if (isAppInstalled(context, APP_PACKAGE_NAME)) {
context.startActivity(context.getPackageManager()
.getLaunchIntentForPackage(APP_PACKAGE_NAME));
} else {
goToMarket(context, APP_PACKAGE_NAME);
}
}
/**
* 检测某个应用是否安装
*
* @param context
* @param packageName
* @return
*/
public static boolean isAppInstalled(Context context, String packageName) {
try {
context.getPackageManager().getPackageInfo(packageName, 0);
return true;
} catch (NameNotFoundException e) {
return false;
}
}
/**
* 判断市场是否存在的方法
*
* @param context
* @param packageName
* 应用市场包名
* @return true or false
*/
public static boolean isAvilible(Context context, String packageName) {
final PackageManager packageManager = context.getPackageManager();// 获取packagemanager
List<PackageInfo> packageInfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息
List<String> NameList = new ArrayList<String>();// 用于存储所有已安装程序的包名
// 从packageInfo中取出包名，放入NameList中
if (packageInfo != null) {
for (int i = 0; i < packageInfo.size(); i++) {
String pn = packageInfo.get(i).packageName;
NameList.add(pn);
}
}
return NameList.contains(packageName);// 判断pName中是否有目标程序的包名，有TRUE，没有FALSE
}
}
3、Toast工具类（不建议使用，请看另外一篇Android 自定义Toast，并且勘误Android工具类里面的ToastUtils）
public class ToastUtils {~
public static Toast toast;
public static boolean isShow = true;
private ToastUtils() {
// 不能被实例化
throw new UnsupportedOperationException("cannot be instantiated");
}
public static void showToast(Context context, String message) {
if (toast == null) {
toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
} else {
toast.setText(message);
}
toast.show();
}
/**
* 屏幕中间位置显示短时间Toast
*
* @param context
* @param msg
*/
public static void ToastShortCenter(Context context, String msg) {
if (isShow) {
if (context != null) {
Toast toast = Toast.makeText(context, msg, Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
}
/**
* 屏幕中心位置长时间显示Toast
*
* @param context
* @param message
*/
public static void ToastLongCenter(Context context, String message) {
if (isShow) {
if (context != null) {
Toast toast = Toast.makeText(context, message,
Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
}
/**
* 自定义显示Toast时间
*
* @param context
* @param message
* @param duration
*/
public static void ToastShow(Context context, String message, int duration) {
if (isShow)
Toast.makeText(context, message, duration).show();
}
}
4、KeyBoardUtils
public class KeyBoardUtils {
public KeyBoardUtils() {
throw new AssertionError();
}
/**
* 打卡软键盘
*
* @param mEditText
* 输入框
* @param mContext
* 上下文
*/
public static void openKeybord(EditText mEditText, Context mContext) {
InputMethodManager imm = (InputMethodManager) mContext
.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(mEditText, InputMethodManager.RESULT_SHOWN);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,
InputMethodManager.HIDE_IMPLICIT_ONLY);
}
/**
* 关闭软键盘
*
* @param mEditText
* 输入框
* @param mContext
* 上下文
*/
public static void closeKeybord(EditText mEditText, Context mContext) {
InputMethodManager imm = (InputMethodManager) mContext
.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(mEditText.getWindowToken(), 0);
}
}
5、AES工具类
public class AESUtils {
// 密钥算法
private static final String KEY_ALGORITHM = "AES";
// AES/CBC/PKCS7Padding 分别对应 加密||解密算法、工作模式、填充方式
private static final String CIPHER_ALGORITHM = "AES/CBC/PKCS7Padding";
// 定义自己的秘钥
public final static String SECRETKEY = "A9e4/vnQTrKF6otAGbM6zGsulKEL7b3x";
// 位移量
public final static String DISPLACEMENT = "9mg+!7ed8b36*w`X";
/**
* 获取KEY
*
* @return
* @throws Exception
*/
private static byte[] getKey() throws Exception {
return SECRETKEY.getBytes(Charset.forName("UTF-8"));
}
/**
* 加密
*
* @param toEncrypt
* 文本
* @return
*
* 加密返回数组
* @throws Exception
*/
@SuppressLint("TrulyRandom")
public static byte[] Encrypt(String toEncrypt) throws Exception {
// 秘钥
Key secretKey = new SecretKeySpec(getKey(), KEY_ALGORITHM);
// libs中bcprov的支持,bouncycastle支持 64 位密钥
Security.addProvider(new BouncyCastleProvider());
Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
// 获取位移，并初始化
final byte[] data = DISPLACEMENT.getBytes();
IvParameterSpec mIvParameterSpec = new IvParameterSpec(data);
// 用 iv 初始化
cipher.init(Cipher.ENCRYPT_MODE, secretKey, mIvParameterSpec);
final byte[] mEncrypted = cipher.doFinal(toEncrypt.getBytes(Charset
.forName("UTF-8")));
final byte[] mSpecEncrypted = new byte[data.length + mEncrypted.length];
System.arraycopy(data, 0, mSpecEncrypted, 0, data.length);
System.arraycopy(mEncrypted, 0, mSpecEncrypted, data.length,
mEncrypted.length);
return mSpecEncrypted;
}
/**
* 加密数据
*
* @param encryption
*
* 文本
* @return
*
* 返回字符串
* @throws Exception
*/
public static String Encryption(String encryption) throws Exception {
byte[] entroyResult = Encrypt(encryption);
String result = new String(Base64.encode(entroyResult, 0), "UTF-8");
return result;
}
/**
* 解密数据
*
* @param toDecrypt
* 文本
* @return <br>
* 返回字符串
* @throws Exception
*/
public static String Decrypt(String decrypt) throws Exception {
byte[] data = Base64.decode(decrypt, 0);
// 秘钥
Key secretKey = new SecretKeySpec(getKey(), KEY_ALGORITHM);
Security.addProvider(new BouncyCastleProvider());
Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
final byte[] mData = DISPLACEMENT.getBytes();
IvParameterSpec mIvParameterSpec = new IvParameterSpec(mData);
cipher.init(Cipher.DECRYPT_MODE, secretKey, mIvParameterSpec);
final byte[] mEncrypted = cipher.doFinal(data);
// 结果
final byte[] result = new byte[mEncrypted.length - mData.length];
System.arraycopy(mEncrypted, mData.length, result, 0, result.length);
return new String(result);
}
}
6、APP版本工具类
public class VersionUtil {
/**
* 获取应用程序名称
*
* @param context
* @return
*/
public static String getAppName(Context context) {
try {
PackageManager packageManager = context.getPackageManager();
PackageInfo packageInfo = packageManager.getPackageInfo(
context.getPackageName(), 0);
int labelRes = packageInfo.applicationInfo.labelRes;
return context.getResources().getString(labelRes);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return null;
}
/**
* 获取版本号
*
* @param context
* @return 当前应用的版本号
*/
public static String getVersion(Context context) {
try {
PackageManager manager = context.getPackageManager();
PackageInfo info = manager.getPackageInfo(context.getPackageName(),
0);
String version = info.versionName;
return version;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
return "";
}
}
/**
* 版本比较
*
* @param nowVersion
* app版本
* @param serverVersion
* 服务器版本
* @return
*/
public static boolean compareVersion(String nowVersion, String serverVersion) {
if (nowVersion != null && serverVersion != null) {
String[] nowVersions = nowVersion.split("\\.");
String[] serverVersions = serverVersion.split("\\.");
if (nowVersion != null && serverVersion != null
&& nowVersions.length > 1 && serverVersions.length > 1) {
int nowVersionFirst = Integer.parseInt(nowVersions[0]);
int serverVersionFirst = Integer.parseInt(serverVersions[0]);
int nowVersionSecond = Integer.parseInt(nowVersions[1]);
int serverVersionSecond = Integer.parseInt(serverVersions[1]);
if (nowVersionFirst < serverVersionFirst) {
return true;
} else if (nowVersionFirst == serverVersionFirst
&& nowVersionSecond < serverVersionSecond) {
return true;
}
}
}
return false;
}
}
7、GlideUtils
话说用开源库的时候应该自行封装一下，为了后面修改方便。
public class GlideUtils {
public GlideUtils(){
throw new AssertionError();
}
/**
* 显示照片
* @param context
* @param imageView
* @param url
*/
public static void displays(Context context, ImageView imageView, Object url) {
Glide.with(context).load(url).skipMemoryCache(true) //跳过内存缓存
.diskCacheStrategy(DiskCacheStrategy.ALL) //硬盘缓存全部
.into(imageView);
}
/**
* 显示图片
* @param context
* @param imageView
* @param url
* @param tag
*/
public static void display(Context context, ImageView imageView, String url, Object tag) {
Glide.with(context).load(url).
error(R.drawable.ic_error).placeholder(R.drawable.ic_progress).into(imageView);
}
public static void display(Context context, ImageView imageView, String url, int progressId) {
RequestManager manager = Glide.with(context);
DrawableTypeRequest<String> load = manager.load(url);
load.error(R.drawable.ic_error).placeholder(new ColorDrawable(Color.GRAY)).into
(imageView);
if (progressId != -1) {
load.placeholder(progressId);
}
}
public static void display(Context context, ImageView imageView, String url) {
display(context, imageView, url, -1);
}
public static void cancel(Context context) {
}
/**
* 设置磁盘缓存大小和位置,这里设置150M
*/
public static void setInnerCacheDir(Context context){
GlideBuilder builder = new GlideBuilder(context);
builder.setDiskCache(new InternalCacheDiskCacheFactory(context, "ImgCache", 150 * 1024 * 1024));
}
/**
* 可以用ExternalCacheDiskCacheFactory来把你的磁盘缓存放到sd卡的公共缓存目录上,这里默认设置150M
*/
public static void setDiskCacheDir(Context context){
GlideBuilder builder = new GlideBuilder(context);
builder.setDiskCache( new ExternalCacheDiskCacheFactory(context, "ImgCache", 150 * 1024 * 1024));
}
/**
* 清除缓存
*/
public static void clearCache(final Context context){
Glide.get(context).clearMemory(); //清理内存缓存
new Thread(new Runnable() {
@Override
public void run() {
Glide.get(context).clearDiskCache(); //清理磁盘缓存
}
}).start();
}
}
8、缓存工具类
public class CacheUtil {
public CacheUtil() {
throw new UnsupportedOperationException("cannot be instantiated");
}
/**
* 得到缓存大小
*
* @param context 上下文
* @return
* @throws IOException
*/
public static String getTotalCacheSize(Context context) throws IOException {
//缓存大小
long cacheSize = getFolderSize(context.getCacheDir());
// 如果SD卡正常挂载才可以创建文件或者写入文件等
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
cacheSize += getFolderSize(context.getCacheDir());
}
return getFormatSize(cacheSize);
}
/**
* 得到临时缓存数据
*
* @param file
* @return
* @throws IOException
*/
public static long getFolderSize(File file) throws IOException {
long size = 0;
//文件
File[] fileList = file.listFiles();
for (int i = 0; i < fileList.length; i++) {
if (fileList[i].isDirectory()) {
size = size + getFolderSize(fileList[i]);
} else {
size = size + fileList[i].length();
}
}
return size;
}
/**
* 清除所有缓存
*/
public static void clearAllCache(Context context) {
//删除缓存
deleteDir(context.getCacheDir());
//如果存在SD卡则删除本地缓存
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
deleteDir(context.getExternalCacheDir());
}
}
/**
* 是否删除文件
*
* @return
*/
public static boolean deleteDir(File dir) {
// 文件不为空并且是一个文件夹时
if (dir != null && dir.isDirectory()) {
//得到文件集合
String[] child = dir.list();
for (int i = 0; i < child.length; i++) {
//是否删除成功
boolean isSuccess = deleteDir(new File(dir, child[i]));
if (!isSuccess) {
return false;
}
}
}
return dir.delete();
}
/**
* 格式化
*
* @return
*/
public static String getFormatSize(double size) {
//KB
double kiloByte = size / 1024;
if (kiloByte<1){
return size+"Byte";
}
//MB
double megaByte=kiloByte/1024;
if (megaByte<1){
//高精度计算结果
BigDecimal result1=new BigDecimal(Double.toString(kiloByte));
//四舍五入
return result1.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"KB";
}
//GB
double gigaByte = megaByte/1024;
if (gigaByte<1){
BigDecimal result2= new BigDecimal(Double.toString(megaByte));
return result2.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"MB";
}
//TB

}
BigDecimal result4= new BigDecimal(teraByte);
return result4.setScale(2,BigDecimal.ROUND_HALF_UP).toPlainString()+"TB";
}
}
9、SharedPreferences封装类
public class SPUtils {
/**
* 保存在手机里面的文件名
*/
public static final String FILE_NAME = "share_data";
/**
* 保存数据的方法，我们需要拿到保存数据的具体类型，然后根据类型调用不同的保存方法

}
/**

* 因为commit方法是同步的，并且我们很多时候的commit操作都是UI线程中，毕竟是IO操作，尽可能异步；
*/
SharedPreferencesCompat.apply(editor);
}
/**
* 得到保存数据的方法，我们根据默认值得到保存的数据的具体类型，然后调用相对于的方法获取值
*
* @param context
* @param key
* @param defaultObject
* @return
*/
public static Object get(Context context, String key, Object defaultObject) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME,
Context.MODE_PRIVATE);
if (defaultObject instanceof String) {
return sp.getString(key, (String) defaultObject);

} else if (defaultObject instanceof Long) {
return sp.getLong(key, (Long) defaultObject);
}
return null;
}
/**
* 移除某个key值已经对应的值
*
* @param context

*/
public static void remove(Context context, String key) {

*/
public static boolean contains(Context context, String key) {

return sp.contains(key);
}
/**

*/
public static Map<String, ?> getAll(Context context) {

return sp.getAll();
}
/**
