当我收到通知并单击向下拖动栏中的选项卡时,消息活动正在启动但未显示收到的消息。
当消息活动处于活动状态时,下一条消息显示良好。
如何显示第一条/开场信息?
感谢。
GCMIntentService.java(部分)
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MessageActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
MessageActivity.class
public class MessageActivity extends Activity {
// label to display gcm messages
TextView lblMessage;
// Alert dialog manager
AlertDialogManager alert = new AlertDialogManager();
// Connection detector
ConnectionDetector cd;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_message);
cd = new ConnectionDetector(getApplicationContext());
// Check if Internet present
if (!cd.isConnectingToInternet()) {
// Internet Connection is not present
alert.showAlertDialog(MessageActivity.this,
"Internet Connection Error",
"U heeft geen verbinding met internet!", false);
// stop executing code by return
return;
}
lblMessage = (TextView) findViewById(R.id.lblMessage);
registerReceiver(mHandleMessageReceiver, new IntentFilter(
DISPLAY_MESSAGE_ACTION));
}
/**
* Receiving push messages
* */
private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String newMessage = intent.getExtras().getString(EXTRA_MESSAGE);
// Waking up mobile if it is sleeping
WakeLocker.acquire(getApplicationContext());
// Showing received message
lblMessage.append(newMessage + "\n");
Toast.makeText(getApplicationContext(), "Nieuw bericht: " + newMessage, Toast.LENGTH_LONG).show();
// Releasing wake lock
WakeLocker.release();
}
};
}

好吧,我这样解决了:
在GCMIntentService.java中添加
notificationIntent.putExtra("message", message);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT );
和MessageActivity.class
TextView message= (TextView) findViewById(R.id.lblMessage);
message.setText(getIntent().getExtras().getString("message"));

BroadcastReceiver
仅在MessageActivity
正在运行时注册。您需要在清单中注册它,以便在MessageActivity
未运行时它可以正常工作。
IIRC你需要延长BroadcastReceiver
才能做到这一点。
