Android 从firebase发送电子推送通知时打开特定活动

我有android应用程序，并尝试接收推送通知。 单击保留通知打开主活动时出现的问题， 我需要在收到来自firebase的推送通知时直接打开特定活动。这是我的密码

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody());
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
        try {
            JSONObject json = new JSONObject(remoteMessage.getData().toString());
            handleDataMessage(json);
        } catch (Exception e) {
            Log.e("Mo", "Exception: " + e.getMessage());
        }
        Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
        startActivity(resultIntent);
    }

    private void handleDataMessage(JSONObject json) {

        if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
            // app is in foreground, broadcast the push message
            Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
            pushNotification.putExtra("message", message);
            LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
            NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
            notificationUtils.playNotificationSound();

            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        } else {
            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        }
    }

您可以在通知中设置挂起的意图。因此，首先创建一个挂起的意图：

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), 0);

然后添加到您的

通知生成器
，在其中定义标题、说明等。。通知中的以下参数：

builder.setContentIntent(contentIntent)

更新：

您的代码中已经有了
notificationcompatingbuilder

替换此项：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody());

为此：

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody())
                .setContentIntent(contentIntent);

你应该考虑使用<代码> PixIdtudio可以在点击通知时启动一个特定的活动。将此添加到您的代码中
    Intent intent = new Intent(this, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, YOUT_REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);

即使未执行
HandleData消息
也可以将代码更改为该消息，但这将允许您在单击通知时启动活动

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));

    //two lines addded
    Intent intent = new Intent(this, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.app_logo_a)
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getNotification().getBody())
            .setContentIntent(contentIntent);//added line
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());
    try {
        JSONObject json = new JSONObject(remoteMessage.getData().toString());
        handleDataMessage(json);
    } catch (Exception e) {
        Log.e("Mo", "Exception: " + e.getMessage());
    }

}

private void handleDataMessage(JSONObject json) {

    if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
        // app is in foreground, broadcast the push message
        Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
        pushNotification.putExtra("message", message);
        LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
        NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
        notificationUtils.playNotificationSound();

    }
}

检查一下这个。。当您收到推送通知或当用户在UI中“单击”通知时，您是否尝试启动活动？在哪里？？加上这个？！！哪里加上这个@莫亚耶达莱塞啊。。打字错误。我修好了。您能再试一次吗？@MoayedAlayseh您是否设置了目标活动？PendingEvent contentIntent=PendingEvent.getActivity（此，0，新意图（此，通知页面类），0）；NotificationCompat.Builder Builder=新建NotificationCompat.Builder（this）.setSmallIcon（R.mipmap.app_logo_a）.setContentTitle（remoteMessage.getData（）.get（“title”）.setContentText（remoteMessage.getNotification（）.getBody（））.setContentIntent（contentIntent）；NotificationManager=（NotificationManager）getSystemService（通知服务）；manager.notify（0，builder.build（））；这是我的代码，当点击进入通知时，应用程序将打开第一个活动！！！
