一、Notification的按钮
相关代码：
/**
* 显示或者刷新通知
*/
private void showNotification() {
notification = new Notification();
notification.flags = Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;
notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
notification.icon = R.drawable.ic_launcher;
notification.tickerText = "点击打开应用";
RemoteViews rv = new RemoteViews(getPackageName(), R.layout.notifi);
String allReslut = BLTPreference.readPreference(this, ConstantPhoneInfo.SP_PREDICTION_RESULT, "");
ArrayList<Programe> list = new ArrayList<>();
String r[] = allReslut.split(",");
for (int i = 0; i < r.length; i++) {
if (!r[i].trim().equals("")) {
Programe p = AppInfoUtil.getProgramDetailByPackageName(this, r[i].trim());
list.add(p);
}
}
Intent buttonIntent = new Intent(ACTION_BUTTON);
if (list.size() > 0) {
rv.setImageViewBitmap(R.id.iv1, BLTViewUtil.drawableToBitmap(list.get(0).icon));
buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV1_ID);
buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(0).packageName);
// 这里加了广播，所及INTENT的必须用getBroadcast方法，注意第二个参数requestCode需要是不同的int值，不然会重置buttonIntent的内容
PendingIntent intent_iv1 = PendingIntent.getBroadcast(this, 1, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.iv1, intent_iv1);
}
if (list.size() > 1) {
rv.setImageViewBitmap(R.id.iv2, BLTViewUtil.drawableToBitmap(list.get(1).icon));
buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV2_ID);
buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(1).packageName);
PendingIntent intent_iv2 = PendingIntent.getBroadcast(this, 2, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.iv2, intent_iv2);
}
if (list.size() > 2) {
rv.setImageViewBitmap(R.id.iv3, BLTViewUtil.drawableToBitmap(list.get(2).icon));
buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV3_ID);
buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(2).packageName);
PendingIntent intent_iv3 = PendingIntent.getBroadcast(this, 3, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.iv3, intent_iv3);
}
if (list.size() > 3) {
rv.setImageViewBitmap(R.id.iv4, BLTViewUtil.drawableToBitmap(list.get(3).icon));
buttonIntent.putExtra(INTENT_BUTTONID_TAG, BUTTON_IV4_ID);
buttonIntent.putExtra(INTENT_PACKAGE_TAG, list.get(3).packageName);
PendingIntent intent_iv4 = PendingIntent.getBroadcast(this, 4, buttonIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.iv4, intent_iv4);
}
notification.contentView = rv;
if (list.size() == 0) {
// 如果没有可预测的数据，则点击进入本应用
rv.setViewVisibility(R.id.iv, View.VISIBLE);
rv.setViewVisibility(R.id.ll, View.GONE);
Intent i1 = new Intent(this, ActHome.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, i1, PendingIntent.FLAG_UPDATE_CURRENT);
notification.contentIntent = contentIntent;
} else {
rv.setViewVisibility(R.id.iv, View.GONE);
rv.setViewVisibility(R.id.ll, View.VISIBLE);
}
this.startForeground(1, notification);
}
/**

public void initButtonReceiver() {

}

/**

*/
public static void collapseStatusBar(Context context) {
try {

Method collapse;
if (Build.VERSION.SDK_INT <= 16) {

} else {

}
二、点击按钮收回系统通知栏
注意：需要在Manifest中添加权限：
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />
代码如下：使用反射
/**
* 关闭下拉通知栏
*
* 需要添加权限：<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />
*
* @param context
*/
public static void collapseStatusBar(Context context) {
try {
Object statusBarManager = context.getSystemService("statusbar");
Method collapse;
if (Build.VERSION.SDK_INT <= 16) {
collapse = statusBarManager.getClass().getMethod("collapse");
} else {
collapse = statusBarManager.getClass().getMethod("collapsePanels");
}
collapse.invoke(statusBarManager);
} catch (Exception localException) {
localException.printStackTrace();
}
}
