单击通知以打开我的活动时的 firebase 消息传递

Question

firebase 工作正常，在状态栏上推送通知，但我的挑战是点击通知时，我希望它带我到我的自定义活动而不是默认启动器，我该怎么做？

public class CustomActivity extends AppCompatActivity {

private static final String TAG = "CustomActivity";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    TextView mymessage = (TextView) findViewById(R.id.mymessage);

    // If a notification message is tapped, any data accompanying the notification
    // message is available in the intent extras. In this sample the launcher
    // intent is fired when the notification is tapped, so any accompanying data would
    // be handled here. If you want a different intent fired, set the click_action
    // field of the notification message to the desired intent. The launcher intent
    // is used when no click_action is specified.
    //
    // Handle possible data accompanying notification message.
    // [START handle_data_extras]
    if (getIntent().getExtras() != null) {
        for (String key : getIntent().getExtras().keySet()) {
            String value = String.valueOf(getIntent().getExtras().get(key));
            Log.d(TAG, "Key: " + key + " Value: " + value);
            //
            Toast.makeText(getApplicationContext() , value , Toast.LENGTH_SHORT).show();


        }

        //Toast.makeText(getApplicationContext() , String.valueOf(getIntent().getExtras().get("message")) , Toast.LENGTH_SHORT).show();


    }
    // [END handle_data_extras]

    Button subscribeButton = (Button) findViewById(R.id.subscribeButton);
    subscribeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // [START subscribe_topics]
            FirebaseMessaging.getInstance().subscribeToTopic("news");
            // [END subscribe_topics]

            // Log and toast
            String msg = getString(R.string.msg_subscribed);
            Log.d(TAG, msg);
            Toast.makeText(CustomActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

    Button logTokenButton = (Button) findViewById(R.id.logTokenButton);
    logTokenButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Get token
            String token = FirebaseInstanceId.getInstance().getToken();

            // Log and toast
            String msg = getString(R.string.msg_token_fmt, token);
            Log.d(TAG, msg);
            Toast.makeText(CustomActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });
}

这是我想在通知计时时打开的自定义活动。通知来自 Firebase 云消息传递。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyFirebaseMsgService";

/**
 * Called when message is received.
 *
 * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
 */
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // [START_EXCLUDE]
    // There are two types of messages data messages and notification messages. Data messages are handled
    // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
    // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
    // is in the foreground. When the app is in the background an automatically generated notification is displayed.
    // When the user taps on the notification they are returned to the app. Messages containing both notification
    // and data payloads are treated as notification messages. The Firebase console always sends notification

    // [END_EXCLUDE]

    // TODO(developer): Handle FCM messages here.
    Log.d(TAG, "From: " + remoteMessage.getFrom());

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        System.out.print("Message data payload :" + remoteMessage.getData());

    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
        System.out.print("Message Notification Body :" + remoteMessage.getNotification().getBody());
    }



    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.


}
// [END receive_message]



/**
 * Create and show a simple notification containing the received FCM message.
 *
 * @param messageBody FCM message body received.
 */
private void sendNotification(String messageBody) {
    Intent intent = new Intent(this, CustomActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_stat_ic_notification)
            .setContentTitle("FCM Message")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

}

这是侦听来自 firebase 的通知的服务。

我找到了答案。只需在我的启动器屏幕上添加此代码并在关闭启动器屏幕并转到预期活动时保存数据即可。

    //When Notification is tapped
    if (getIntent().getExtras() != null) {
        //init message
        String message = String.valueOf(getIntent().getExtras().get("message"));
        String title = String.valueOf(getIntent().getExtras().get("title"));
        //save the message
        MySharedPreference.save(getApplicationContext() , "message" , message);
        MySharedPreference.save(getApplicationContext() , "title" , title);
        startActivity(new Intent(getApplicationContext() , MainActivity.class));
        finish();
    }
