在Android中单击Firebase通知时将数据发送到活动

[英]Send data to activity when Firebase notification is clicked in Android

在我的应用程序中,我想使用fireBase进行通知
我想在单击通知时(当应用关闭时,我的意思是应用处于background )将putExtra数据发送到mainActivity
我写下面的代码,但是当单击通知时 (在应用程序中是后台),但显示getStringExtranull

MyNotificationManager类:

public class MyNotificationManager {

    private Context mCtx;
    private Uri soundUri;
    private static MyNotificationManager mInstance;

    public MyNotificationManager(Context context) {
        mCtx = context;
    }

    public static synchronized MyNotificationManager getInstance(Context context) {
        if (mInstance == null) {
            mInstance = new MyNotificationManager(context);
        }
        return mInstance;
    }

    public void displayNotification(String title, String body) {

        soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        Intent intent = new Intent(mCtx, MainActivity.class);
        intent.putExtra("fcm_notification", "Y");

        PendingIntent pendingIntent = PendingIntent.getActivity(mCtx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mCtx, Constants.NOTIF_CHANNEL_ID)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(title)
                .setSound(soundUri)
                .setAutoCancel(true)
                .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
                .setContentText(body)
                .setContentIntent(pendingIntent);

        NotificationManager mNotifyMgr = (NotificationManager) mCtx.getSystemService(NOTIFICATION_SERVICE);

        if (mNotifyMgr != null) {
            mNotifyMgr.notify(1, mBuilder.build());
        }
    }
}

MyFirebaseMessagingService类别:

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        showNotify(remoteMessage.getFrom(), remoteMessage.getNotification().getBody());
    }

    private void showNotify(String title, String body) {
        MyNotificationManager myNotificationManager = new MyNotificationManager(getApplicationContext());
        //myNotificationManager.displayNotification(title, body);
        myNotificationManager.displayNotification(title, body);
    }
}

MainActivity类:

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

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            checkIntent();
        }
    }, 1000);
}

private boolean checkIntent() {
    String value = getIntent().getStringExtra("fcm_notification");
    Toast.makeText(context, "" + value, Toast.LENGTH_SHORT).show();

    if (value == null) return false;

    if (value.equals("Y")) {
        startActivity(new Intent(this, LandingActivity.class));
        // open one activity.

    } else if (value.equals("another thing")) {
        // open another activity.
    }

    finish();
    return true;
}

单击通知(在应用程序上为后台)时,在Toast中显示此行的消息String value = getIntent().getStringExtra("fcm_notification");

我该如何解决?

从控制台发送通知时,请从“高级选项”中添加自定义数据:

在此处输入图片说明

由于某些原因,firebase不允许密钥以fcm开头。 您不能使用fcm_notification 使用其他密钥。

对于上图,请按以下方式接收密钥:

String value = getIntent().getStringExtra("test_key");

尝试这个:

Intent intent = new Intent(mCtx, MainActivity.class);
intent.putExtra("EXTRA_DATA", title);

并获得:

String value = getIntent().getStringExtra("EXTRA_DATA");

最好更改密钥。 另外,似乎您需要从控制台发送数据,然后再将数据发送到另一个Activity

我使用了当前的通知title来检查它是否返回标题。如果返回了值,那么请尝试从控制台发送数据。
