點擊通知欄觸發廣播的多種方式

1、靜態註冊廣播

編輯廣播類

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e("TAG","觸發");
    }
}

PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,new Intent(this,MyReceiver.class),PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        builder = new NotificationCompat.Builder(this,"通知渠道id");
        builder.setContentIntent(pendingIntent);

記得註冊

<receiver android:name=".MyReceiver"/>

如果使用混合開發的話廣播類裏面可能會要用到一個上下文對象，這樣可以使用內部類的方式，將廣播類寫在需要使用的類中，需要加上static修飾，註冊的方式也變爲

<receiver android:name=".MainActivity$MyReceiver"/>

 

2、動態註冊廣播

可能是對於reactnative來說最好用的方式，這樣的好處是可以在newBroadCastReceiver中直接使用getReactApplicationContext()

public BroadcastReceiver newBroadCastReceiver = new BroadcastReceiver() {
     @Override
     public void onReceive(Context context, Intent intent) {
         Log.e("TAG","觸發");
     }
 };

private static String BROADCASTNAME = "com.vision.broadcast";

IntentFilter intentFilter = new IntentFilter(BROADCASTNAME);
        registerReceiver(newBroadCastReceiver,intentFilter);
        broadcastIntent = new Intent();
        broadcastIntent.setAction(BROADCASTNAME);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,broadcastIntent,PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        builder = new NotificationCompat.Builder(this,"渠道id");
        builder.setContentTitle("title");
        builder.setContentText("context");
        builder.setWhen(System.currentTimeMillis());
        builder.setContentIntent(pendingIntent);
        builder.setSmallIcon(R.drawable.ic_chat);
        builder.setAutoCancel(true);
        manager.notify(2,builder.build());
