我的某个游戏有问题。这是基于时间的益智游戏,我有它的问题。当用户按下Android设备上的开/关按钮时,游戏不会停止,但计时器会一直持续到游戏结束。当用户再次打开屏幕时,他可以在屏幕上看到游戏。但是我希望在用户按下开/关按钮游戏时暂停。
有什么建议吗?我在编程方面很新,所以请解释一下这个非常基本的方法。
谢谢大家!
编辑。定时器代码
private void initializeProgressBar() {
//initialize progressbar
progress = ApplicationConstants.GAME_TIME;
mProgress = (ProgressBarDetermininate) findViewById(R.id.progressDeterminate);
mProgress.setMax(progress);
mProgress.setProgress(progress );
timer = new Timer();
progressBarUpdateTask = new ProgressBarUpdateTask();
timer.schedule(progressBarUpdateTask, 20, 20);
}
class ProgressBarUpdateTask extends TimerTask {
@Override
public void run() {
runOnUiThread(new Runnable(){
@Override
public void run() {
progress-=1;
if(progress==0)
{
TimeOver();
}
mProgress.setProgress(progress);
}
});
}
@Override
protected void onResume() {
super.onResume();
}
@Override
protected void onPause() {
super.onPause();
this.timer.cancel();
}

在游戏运行的“活动”上下文中,以onStop()
或onPause()
(根据您的需要)暂停游戏。

我假设你正在使用android的活动......
@Override
protected void onResume() {
super.onResume();
// Resume the timer or show a button for the user to press when ready
// !!! Also check if timer exits because onResume is called before onCreate!!!
}
@Override
protected void onPause() {
super.onPause();
// Pause the timer
}

执行此操作的一种方法是检测用户状态,这是一个示例
在游戏开始时LockService
startService(new Intent(getApplicationContext(), LockService.class));
<强> LockService.java 强>
public class LockService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
final IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_USER_PRESENT);
final BroadcastReceiver mReceiver = new ScreenReceiver();
registerReceiver(mReceiver, filter);
return super.onStartCommand(intent, flags, startId);
}
public class LocalBinder extends Binder {
LockService getService() {
return LockService.this;
}
}
}
然后最后是你可以停止游戏的BroadcastReceiver
。
<强> ScreenReceiver.java 强>
public class ScreenReceiver extends BroadcastReceiver {
public static boolean wasScreenOn = true;
@Override
public void onReceive(final Context context, final Intent intent) {
Log.e("LOB","onReceive");
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
// do whatever you need to do here
wasScreenOn = false;
/* PAUSE THE GAME HERE*/
Log.e("LOB","wasScreenOn"+wasScreenOn);
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
// and do whatever you need to do here
wasScreenOn = true;
}else if(intent.getAction().equals(Intent.ACTION_USER_PRESENT)){
}
}
}
正如其他答案中正确提到的,您也可以使用onPause()方法
@Override
protected void onPause() {
super.onPause();
// stop the game
}

当您按下屏幕或电源按钮时,将调用应用程序的暂停方法,当您再次按电源按钮时,将调用应用程序onResume方法,您应该暂停onPause中的计时器并在onResume中恢复它。
