对话框说明
使用 DialogFragment 实现，创建 DialogUtils 工具类
package com.ningcui.mylibrary.utiils;
import android.app.DialogFragment;
import android.app.Fragment;
import android.app.FragmentTransaction;
import android.content.Context;
import android.support.v4.app.FragmentActivity;
import android.view.Gravity;
import android.view.View;
import com.ningcui.mylibrary.viewLib.dialog.AbAlertDialogFragment;
import com.ningcui.mylibrary.viewLib.dialog.AbProgressDialogFragment;
import com.ningcui.mylibrary.viewLib.dialog.AbProgressHorizontalDialogFragment;
import com.ningcui.mylibrary.viewLib.dialog.AbSampleDialogFragment;

普通对话框
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle("温馨提醒");
builder.setMessage("您已经打开 android.support.v7.app.AlertDialog");
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});
builder.show();
横向进度对话框
progressHortionalDialog = new ProgressDialog(mContext, android.support.v7.app.AlertDialog.BUTTON_NEUTRAL);
if (title != null) {
progressHortionalDialog.setTitle(title);
}
if (message != null) {
progressHortionalDialog.setMessage(message);
}
progressHortionalDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressHortionalDialog.setIndeterminate(false);
progressHortionalDialog.setMax(100);
progressHortionalDialog.setCanceledOnTouchOutside(false);
progressHortionalDialog.setCancelable(true);
progressHortionalDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
dialog.dismiss();
}
});
常用下拉刷新
xml 中将 AbPullToRefreshView 套在 继承与ScrollView的组件最外层。例如 ScrollView ListView WebView GridView
<com.ningcui.mylibrary.viewLib.refresh.AbPullToRefreshView
android:id="@+id/pulltofreshView"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ListView
android:id="@+id/pull_listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:divider="@color/gray_bg"
android:dividerHeight="4px" />
</com.ningcui.mylibrary.viewLib.refresh.AbPullToRefreshView>
设置 下拉刷新功能
pulltofreshView.setLoadMoreEnable(true);
pulltofreshView.setPullRefreshEnable(true);
pulltofreshView.setOnHeaderRefreshListener(new AbPullToRefreshView.OnHeaderRefreshListener() {
@Override
public void onHeaderRefresh(AbPullToRefreshView abPullToRefreshView) {
getData();
}
});
pulltofreshView.setOnFooterLoadListener(new AbPullToRefreshView.OnFooterLoadListener() {
@Override
public void onFooterLoad(AbPullToRefreshView abPullToRefreshView) {
loadData();
}
});
加载数据结束
pulltofreshView.onFooterLoadFinish();
刷新数据结束
pulltofreshView.onHeaderRefreshFinish();
自定义SwiperefreshLayout 支持加载
使用方法
// 设置下拉进度的背景颜色，默认就是白色的
swipeRefreshView.setProgressBackgroundColorSchemeResource(android.R.color.white);
// 设置下拉进度的主题颜色
swipeRefreshView.setColorSchemeResources(R.color.colorAccent, R.color.colorPrimary, R.color.colorPrimaryDark);
// 下拉时触发SwipeRefreshLayout的下拉动画，动画完毕之后就会回调这个方法
swipeRefreshView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
// TODO 获取数据
final Random random = new Random();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
mList.add(0, "测试数据" + random.nextInt(100) + "号");
mAdapter.notifyDataSetChanged();
Toast.makeText(SwipeRefreshLayoutActivity.this, "刷新了一条数据", Toast.LENGTH_SHORT).show();
// 加载完数据设置为不刷新状态，将下拉进度收起来
swipeRefreshView.setRefreshing(false);
}
}, 1200);
}
});
// 设置下拉加载更多
swipeRefreshView.setOnLoadListener(new SwipeRefreshView.OnLoadListener() {
@Override
public void onLoad() {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// 添加数据
for (int i = 30; i < 35; i++) {
mList.add("测试数据" + i + "号");
// 这里要放在里面刷新，放在外面会导致刷新的进度条卡住
mAdapter.notifyDataSetChanged();
}
Toast.makeText(SwipeRefreshLayoutActivity.this, "加载了" + 5 + "条数据", Toast.LENGTH_SHORT).show();
// 加载完数据设置为不加载状态，将加载进度收起来
swipeRefreshView.setLoading(false);
}
}, 1200);
}
});
说明： SwiperefreshLayout与 ViewPager 等横向滑动混用 会有异常。需要对ViewPager 进行一些修改 后续会提及
