我想使用Firebase通知服务获取通知消息。我从Firebase发送消息,没关系。活动在后台时如何接收事件总线事件
我想要得到这个通知,如果用户在MainActivity
中运行,我也想使用对话框显示弹出窗口。
如果用户运行其他活动,例如SettingActivity
或ProfileActivity
,则无论如何通知处理和用户运行MainActivity
弹出突然出现。
为此,我使用Greenbot Eventbus。当我在MainActivity
里面并且通知出现时它看起来很好。但是当我在另一个Activity
通知没有来。
如何处理此消息,直到MainActivity
?
public class NotificationService extends FirebaseMessagingService {
private static final String TAG = "evenBus" ;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d(TAG, "onMessageReceived");
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
// do nothing if Notification message is received
Log.d(TAG, "Message data payload: " + remoteMessage.getNotification().getBody());
String body = remoteMessage.getNotification().getBody();
EventBus.getDefault().post(new NotificationEvent(body));
}
}
}
MainActiviy
@Override
protected void onResume(){
EventBus.getDefault().register(this);
}
// This method will be called when a MessageEvent is posted (in the UI thread for Toast)
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(NotificationEvent event) {
Log.v("onMessageEvent","Run");
Toast.makeText(MainActivity.this, event.getBody(), Toast.LENGTH_SHORT).show();
alertSendActivity("title",event.getBody());
}
@TargetApi(11)
protected void alertSendActivity(final String title,final String data) {
alt = new AlertDialog.Builder(this,
AlertDialog.THEME_DEVICE_DEFAULT_LIGHT).create();
alt.setTitle(title);
alt.setMessage(data);
alt.setCanceledOnTouchOutside(false);
alt.setCancelable(false);
alt.setButton(AlertDialog.BUTTON_NEUTRAL, getString(R.string.ok),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
alt.dismiss();
}
});
alt.show();
}
protected void onStop() {
super.onStop();
EventBus.getDefault().unregister(this);
}
您节省了我的时间。谢谢 !! – TeyteyLan
