基本上我有一个带有开始按钮的菜单类，它在线程中启动一个新的游戏活动。
在 Game 类中，我实例化了一个 Count 对象（它扩展了 CountDownTimer）。
启动游戏活动时，我收到 ANR 错误，我相信它是由计时器引起的，因为我已将其注释掉并且它工作得很好。坦率地说，我不知道如何解决这个问题；我尝试了不同的方法但失败了。 编辑后的代码*最后是 Logcat *
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);
}
}
