基本上我有一个带有启动按钮的Menu-class，可以在一个线程中启动一个新的游戏活动。开始新的活动时发生ANR错误
在Game类中，我实例化了一个Count对象（它扩展了CountDownTimer）。
当开始游戏活动时，我得到一个ANR错误，我相信它是由计时器引起的，因为我已经评论过它，它工作得很好。坦率地说，我不知道如何解决这个问题。我尝试过不同的方法，但失败了。 编辑的代码 * logcat的末 *
public class Menu extends Activity {
Button start, highscores, exit;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
addListenerOnButton();
}
private void addListenerOnButton() {
start = (Button) findViewById(R.id.start);
start.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
startActivity(new Intent("net.fb.clauz.GAME"));
};
});
highscores = (Button) findViewById(R.id.highscores);
highscores.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
}
});
exit = (Button) findViewById(R.id.exit);
exit.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
finish();
System.exit(0);
}
});
}
}
public class Game extends Activity {
Button button;
TextView score;
public static TextView timeleft;
int x = 0;
public Counter count;
public static boolean running=true;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
count = new Counter(30000, 1000);
timeleft = (TextView) findViewById(R.id.timeleftTitle);
gameThread = new Thread(new Runnable() {
public void run() {
while (running) {
addListenerOnButton();
count.start();
}
}
});
gameThread.start();
}
private void addListenerOnButton() {
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
x++;
score = (TextView) findViewById(R.id.score);
score.setText(String.valueOf(x));
}
});
}
}
public class Counter extends CountDownTimer{
public Counter(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
// TODO Auto-generated constructor stub
}
@Override
public void onFinish() {
// TODO Auto-generated method stub
Game.running = false; // stop the game
//need to implement action to return to the buttons menu.
}
@Override
public void onTick(long millisUntilFinished) {
// TODO Auto-generated method stub
Game.timeleft.setText("Left: " + millisUntilFinished/1000);
System.out.println(millisUntilFinished/1000);
}
}

如果显示ANR，则应该添加logcat。 –
我认为你只是在主线程上做了太多的事情，导致你的应用程序“ANR”。你应该使用更多的线程（例如，你的while线程对于mainthread来说太多了） – Sprigg
感谢您的回复。我会尝试添加一个新线程来保持一段时间。 –
