这是我发送消息的GcmIntentService类。问题是当我点击推送通知消息时，它打开了主要活动。但我想打开这个特殊的片段。我知道sendNotification()方法会发生一些变化。谁能告诉我如何打开推送通知的点击上的特定片段?
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:-

管理一些标志，通过Intent将通知信息传递给MainActivity
在MainActivity中使用switch case或if/else，如果您正在接收特定的标志/数据，则加载所需的片段。
Intent passIntent = new Intent(this, MainActivity.class);
passIntent.putExtra("flag","some value");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, passIntent, 0);
在MainActivity.java
if(getIntent().hasExtra("flag")){
if(getIntent.getStringExtra("flag").equalsIgnorCase("some value"))
{
//write code to load your fragment.
}
}
