Question

我正在尝试在收到新通知时打开一个片段。为此，我使用BroadcastReceiver。问题是我没有在sendNotification类FirebaseMessagingService类中的onCreate方法的活动中收到消息。我认为问题是我在// Globally declared private IntentFilter mIntentFilter; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); // Open a fragment automatically if (findViewById(R.id.frame) != null) { if (savedInstanceState != null) { return; } myFragmentManager = getSupportFragmentManager(); myFragmentTransaction = myFragmentManager.beginTransaction(); myFragmentTransaction.replace(R.id.frame, new ProdList()).commit(); } mIntentFilter = new IntentFilter(); mIntentFilter.addAction("com.sam.CUSTOM_INTENT"); } @Override protected void onResume() { super.onResume(); registerReceiver(mReceiver, mIntentFilter); } @Override protected void onPause() { super.onPause(); unregisterReceiver(mReceiver); } private BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("com.sam.CUSTOM_INTENT")) { Toast.makeText(getApplicationContext(), "GOT MESSAGE", Toast.LENGTH_SHORT).show(); InventoryList il = new InventoryList(); replaceFragment(il,"IL"); } } };内声明了IntentFilter，当我点击推送通知时它没有被调用。还有其他办法吗？

@Override
    public void onMessageReceived(RemoteMessage remoteMessage) {        

        if (remoteMessage.getData().size() > 0) {
            for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
                
                String value = entry.getValue();
               
                try {
                    JSONObject obj = new JSONObject(value);
                    
                    sendNotification(obj.getString("message"),"SUCCESS");
                    

                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

        }


    }
	
	
	private void sendNotification(String messageBody, String param) {
        Intent intent = new Intent(this, HomeActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
		intent.setAction("MESSAGE");

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_com.sam.CUSTOM_INTENTr)
                .setContentTitle("Nika")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());
    }

如果您希望BroadcastReceiver获取广播，您必须实际发送广播。将此代码放入onMessageReceived()：

Intent intent = new Intent("com.sam.CUSTOM_INTENT");
context.sendBroadcast(intent);

此代码段将使用IntentFilter匹配操作"com.sam.CUSTOM_INTENT"将广播发送到所有已注册的BroadcastReceivers。

因此，对于当前的实现，您的活动将在恢复时进行广播。

从Firebase onMessageReceived打开片段
