Question

我希望在收到通知后显示activity而不点击通知Activity必须打开。我正在使用FCM进行通知发送。

如何在不点击通知的情况下打开Activity？

我正在使用它，但它没有打开活动：

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyFirebaseMsgService";
String messageContent = "";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    // TODO(developer): Handle FCM messages here.
    messageContent = remoteMessage.getData().get("message");
    showNotification(remoteMessage.getData().get("message"));
    postToastMessage(remoteMessage.getData().get("message"));
    Log.d(TAG, "From: " + remoteMessage.getFrom());


}

public void postToastMessage(final String message) {
    Handler handler = new Handler(Looper.getMainLooper());

    handler.post(new Runnable() {

        @Override
        public void run() {
            Toast.makeText(getApplicationContext(), message +" received", Toast.LENGTH_LONG).show();

            Intent newIntent = new Intent(MyFirebaseMessagingService.this, CallActivity.class);
            newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(newIntent);

        }
    });
}

private void showNotification(String message) {

    Intent i = new Intent(this, CallActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);


    NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle(" Test")
            .setContentText(message)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentIntent(pendingIntent);

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    manager.notify(0,builder.build());
}
}

我收到此错误

FA: Discarding data. Failed to send event to service

试试这个，可能对你有帮助，

在onMessageReceived（）方法中添加此代码，

 Intent intent = new Intent(MyFirebaseMessagingService.this, NotificationActivity.class);//here put your activity name which you want to open
        intent.putExtra("isNotification", true);
        intent.putExtra("message", message);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);

我在NotificationActivity.class中简单地获取消息

 if (getIntent().getBooleanExtra("isNotification", false)) {
        message = getIntent().getStringExtra("message");
        txt_message.setText(message);
    }

添加此内容，

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {


    Log.e(TAG, "From: " + remoteMessage.getFrom());
    Log.e(TAG, "onMessage receiveddd: " + remoteMessage.getData());
    //  Log.e(TAG, "onMessage notification: " + remoteMessage.getNotification().getBody());

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.e("notification background", String.valueOf(remoteMessage.getData()));
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());

        Map<String, String> data = remoteMessage.getData();
        String deviceID = data.get("DeviceID");
        String message = data.get("Message");



        Log.e("value11111111", deviceID);
        Log.e("value222222222", message);


        Intent intent = new Intent(MyFirebaseMessagingService.this, NotificationActivity.class);
        intent.putExtra("isNotification", true);
        // intent.putExtra("title", value1);
        intent.putExtra("message", message);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);

        //   sendNotification("message received");

    }
 }

比邮递员，发送此请求

{
 "data":{
 "DeviceID":"",// pass here your DeviceID
 "Message":"hiiii" // pass here your message
},
"to":""// pass here ypur tocken
  }

在您的代码中创建一个BaseActivity，扩展AppComatActivity，所有其他活动扩展基本活动，在show通知中通过新活动广播您的意图并使接收者进行基本活动，在该接收者中您可以打开您的活动
