我收到来自fcm的通知。但问题是当我点击通知消息时。它包含消息正文。当我尝试将额外的内容放入intent并尝试从intentgetExtras()时，我总是从intent中得到空。
下面是我的代码。有人可以帮助我解决这个问题吗？ 提前谢谢。

演示活动.java
我试图从intent那里获得额外内容的活动。onCreate()我试图获取intent额外

String message = intent.getStringExtra("message");
Toast.makeText(getApplicationContext(), "Push notification: " + message, Toast.LENGTH_LONG).show();
txtMessage.setText(message);
}
}
};
displayFirebaseRegId();
Intent intent = getIntent();
String extraAddress = intent.getStringExtra("message");
Toast.makeText(this, "got message:"+extraAddress, Toast.LENGTH_SHORT).show();
}
// Fetches reg id from shared preferences
// and displays on the screen
private void displayFirebaseRegId() {
SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
String regId = pref.getString("regId", null);
Log.e(TAG, "Firebase reg id: " + regId);
if (!TextUtils.isEmpty(regId))
txtRegId.setText("Firebase Reg Id: " + regId);
else
txtRegId.setText("Firebase Reg Id is not received yet!");
}
@Override
protected void onResume() {
super.onResume();
// register GCM registration complete receiver
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.REGISTRATION_COMPLETE));
// register new push message receiver
// by doing this, the activity will be notified each time a new message arrives
LocalBroadcastManager.getInstance(this).
registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.PUSH_NOTIFICATION));
// clear the notification area when the app is opened
NotificationUtils.clearNotifications(getApplicationContext());
}
@Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
super.onPause();
}
}
当我点击通知时，我总是从intent那里得到null。 谢谢。
在VisualogyxMessagingService.java你首先检查if (remoteMessage.getNotification() != null)并通过handleNotification(remoteMessage.getNotification().getBody());发送通知，在这种情况下，resultIntent.putExtra("message", message);放入您的Intent然后触发DemoActivity.java。
但是，您不会立即return，导致您的代码继续检查if (remoteMessage.getData().size() > 0)，这也发送另一个意图resultIntent.putExtra("json", hashMap);，"json"字段取代您之前的通知发送(因为它是相同的通知通道和 ID(。因此，这个新Intent只有一个"json"字段，而没有"message"字段。要解决此问题，请尝试在第一次if检查后放置一个return，如下所示：
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
handleNotification(remoteMessage.getNotification().getBody());
return;
// this method is called when i tap on notification if notification contains only message.
}
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString().replace("\n", " "));
HashMap<String, String> hashMap = new HashMap<>(remoteMessage.getData());
handleDataMessage(hashMap);
}
}
在你的DemoActivity.java
Intent intent = getIntent();
HashMap<String, String> jsonData = intent.getSerializableExtra("json");
String message = intent.getStringExtra("message");
你正在添加"json"和"message"的意图。
尝试拨打intent.hasExtra("json")或intent.hasExtra("message")
