我几乎完成了我正在制作的这个玩具应用游戏。
问题: 我的通知总是显示我的计数器为 30000。为什么它没有计时?
我所做的: 我实现了一个简单的服务类和一个自定义计时器来计时。最终,一旦我确定计时器正在工作,我将退出整个游戏。
这是我的代码:
package com.example.redshirtmarblez;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.CountDownTimer;
import android.os.IBinder;
import android.widget.Toast;
public class TimingService extends Service{
public long counter = 30000;
private Context ctx;
private Activity localActivity;
private NotificationManager nm;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate()
{
super.onCreate();
nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
declareNotification();
timer.start();
//Toast.makeText(this, "Timer is :" + counter, Toast.LENGTH_LONG).show();
//showNotification();
}
public void getActivity(Activity activity)
{
localActivity = activity;
}
//count to end the game
public CountDownTimer timer = new CountDownTimer(30000, 1000){
public void onTick(long millisUntilFinished){
counter = millisUntilFinished / 1000;
}
public void onFinish(){
counter = 0;
//Kill the game
int i = android.os.Process.myPid();
android.os.Process.killProcess(i);
}
};
/*
* Show a notification while this service is running
*/
public void declareNotification()
{
//Declare a new notification
Notification notification = new Notification(R.drawable.ic_launcher, "A New Notification", System.currentTimeMillis());
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
Intent intent = new Intent(this, TimingService.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "herp", "counter: " + counter, activity);
//This is clearly not 1337, but a good joke
startForeground(1337, notification);
}
}
当它运行时,所有这一切都是显示“新通知”,然后更改为“herp 计数器:30000”。但是,此通知永远不会改变。它只是保持 30000。为什么?我以为我通过使标志持续存在来解决这个问题?
