原理：

請求系統發送一個廣播，在本程序接收該廣播，并做一系列的操作，屬于跨進程的開發

1、點擊控件請求系統發送廣播

public void doClick(View v) {switch (v.getId()) {case R.id.btn_notification:sendNotification();// 發送通知break;

}

2、在通知欄需要顯示的通知樣式

/*** 自定義*/PRivate void sendNotificationZidinyi() {NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);Builder builder = new Builder(MainActivity.this);RemoteViews views = new RemoteViews(getPackageName(), R.layout.notification_zidinyi);//給RemoteViews添加點擊意圖Intent activityIntent = new Intent(MainActivity.this,MainActivity.class);PendingIntent pi5 = PendingIntent.getActivity(MainActivity.this, 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);views.setOnClickPendingIntent(R.id.btn_startActivity, pi5);//給播放按鈕添加點擊意圖Intent broadIntent = new Intent("ACTION_SEND_BROADCAST");PendingIntent broadCastPi = PendingIntent.getBroadcast(MainActivity.this, 0, broadIntent , Context.BIND_DEBUG_UNBIND);views.setOnClickPendingIntent(R.id.img_player, broadCastPi);builder.setContentTitle("").setTicker("自定義").setSmallIcon(R.drawable.small_pic).setContent(views );Notification notifi = builder.build();manager.notify(555,notifi);}

3、動態注冊廣播接收者

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);receiver = new PlayerBroadcastReceiver();IntentFilter filter = new IntentFilter();filter.addAction("ACTION_SEND_BROADCAST");registerReceiver(receiver, filter);}

4、寫一個清除通知的方法，在其生命周期結束時自行清除

private void clearNotification() {// 單例系統服務，可重復創建NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);manager.cancel(NOTIFI_MANAGER_ID);}

@Overrideprotected void onDestroy() {// TODO Auto-generated method stubisDoing=false;NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);manager.cancel(588);unregisterReceiver(receiver);super.onDestroy();}
