这是我发送消息的GcmIntentService类。问题是,当我点击推送通知消息时,它打开主要活动。但我想打开特定的片段。我知道有些更改将在sendNotification()方法中。任何人都可以告诉我如何在点击推送通知时打开特定片段?

public class GcmIntentService extends IntentService {

    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    private final static String TAG = "GcmIntentService";

    public GcmIntentService() {
        super("GcmIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();


        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                    .equals(messageType)) {
                sendNotification("Send error: " + extras.toString());

            } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                    .equals(messageType)) {
                sendNotification("Deleted messages on server: " + extras.toString());

            } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                    .equals(messageType)) {

                for (int i = 0; i < 5; i++) {
                    Log.d(TAG, " Working... " + (i + 1) + "/5 @ "
                            + SystemClock.elapsedRealtime());
                    try {
                        Thread.sleep(5000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }

                sendNotification(extras.getString("message"));
            }
        }      WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }    


    private void sendNotification(String msg) {
        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);

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


        NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(getNotificationIcon())
                .setContentTitle("Telepoh")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg)
                .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);

        mBuilder.setContentIntent(contentIntent);
        mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
        mBuilder.setAutoCancel(true);

        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

    private int getNotificationIcon() {
        boolean useWhiteIcon = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP);
        return useWhiteIcon ? R.drawable.gcm : R.drawable.push_icon;
    }
}

这是我想在点击推送通知消息时打开的片段: -

管理一些标记,并通过MainActivity将通知信息传递给Intent

MainActivity中使用switch case或if / else,如果您正在接收特定标志/数据,请加载所需的片段。

Intent passIntent = new Intent(this, MainActivity.class);
passIntent.putExtra("flag","some value");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, passIntent, 0);
您的MainActivity.java

中的

if(getIntent().hasExtra("flag")){
    if(getIntent.getStringExtra("flag").equalsIgnorCase("some value"))
    {
          //write code to load your fragment.
    }
}
