计时器行为只有当我触摸显示屏（OnTouchListener） [英] Timer act only if i touch the display (OnTouchListener)

问题描述

定时器工作正常。问题是，该方法_dw.newgame（）刚刚被执行（如果两秒以上），如果我触摸显示屏。也许它也有东西做的OnTouchListener？

The Timer works fine. The problem is that the method _dw.newgame() just get executed(if two seconds are over) if i touch the display. Maybe it have sth to do with the "OnTouchListener" ?

public class DrawView extends View implements OnTouchListener{
Timer timer = new Timer();

公共DrawView（上下文的背景下）
{
timer.schedule（新任务（这一点），0，2000）;
}
公共布尔onTouch（查看视图，MotionEvent事件）
{}
}

public DrawView(Context context) { timer.schedule(new Task(this),0, 2000); } public boolean onTouch(View view, MotionEvent event) {} }

类任务扩展的TimerTask
{
私人DrawView _dw;
公众任务（DrawView DW）{this._dw = DW;}
公共无效的run（）
{_dw.newgame（）; }
}

class Task extends TimerTask { private DrawView _dw; public Task(DrawView dw){ this._dw = dw;} public void run() { _dw.newgame(); } }

推荐答案

也许你应该开始在的onCreate 方法计时器：

Maybe you should start the timer in the onCreate method:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(Bundle savedInstanceState);
    timer = new Timer();
    timer.schedule(new Task(this), 0, 2000);
}

与处理第二个尝试：

second try with handler:

public class DrawView extends View implements OnTouchListener{
    private Timer timer = new Timer();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(Bundle savedInstanceState);

        timer = new Timer();
        timer.schedule(new TimerTask() {
            public void run() {
                handler.sendEmptyMessage();
            }
        }, 0, 2000);
    }

    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            newgame();
        }
    };
}

我没编译这个，但它应该像这样工作。结果
我注意到另一件事：我想newgame（）应该只被调用一次。

I did not compile this but it should work like this.
I noticed another thing: I suppose newgame() should only be called once.

timer.schedule(new Task(this), 0, 2000);

确实，每2秒
