android - 我可以通过从另一个线程调用 onTouch() 方法来安全地将触摸事件分派(dispatch)给主要 Activity 吗？

Question

请告诉我这种方法是否安全，或者我可以使用什么代替普通线程来安全地将触摸事件分派(dispatch)到我的 Activity ，以便测试从该 onTouch() 方法触发的整个流程女巫。

//this is the thread which fires Touch Events to my main activity
public class Monkey extends Thread {

    Run r;
    float x,y;
    public Monkey (Run a)
    {
        r = a;
    }

    public void run()
    {
        int i = 0;
        while(i<10000)

        {
            r.onTouch(r.geView(),
                MotionEvent.obtain(SystemClock.uptimeMillis(), 
                SystemClock.uptimeMillis(), 2, x++, y++, 0));
        }
    }
}

// and this is the main activity
public class Run extends Activity implements OnTouchListener{
    private GLSurfaceView glSurface;

    public View geView()
    {
        return glSurface;
    }

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        glSurface = new GLSurfaceView(this);
        glSurface.setOnTouchListener(this);
        setContentView(glSurface);
        m = new Monkey(this);
    }

    public boolean onTouch(View v, MotionEvent event) 
    {
        //if from here i make other calls to classes that update my glsurface will my application eventualy crash?
    }
}

利用单例类

Singleton architecture
