在模拟器中测试触摸功能

Question

我尝试开发一个Android应用程序。我有以下代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); 
    CardImage = (ImageView)findViewById(R.id.CardImage);
    CardImage.setOnTouchListener(this);
}

public boolean onTouch(View v, MotionEvent event)  
{ 
    if(event.getAction() == MotionEvent.ACTION_UP)
    {
        System.out.println("Touch!");
    }

    return true;
}

如何在模拟器中调试Ontouch功能？我尝试用鼠标拖动图像切换，但没有任何反应。

谢谢你的帮助！

试试这个代码（注意：未经测试）

 CardImage.setOnTouchListener(new OnTouchListener() {  
         @Override
         public boolean onTouch(View v, MotionEvent event) {
          int X = (int) event.getX();
          int Y = (int) event.getY();
          int action = event.getAction();
          if (action == MotionEvent.ACTION_UP){
          TranslateAnimation anim = new TranslateAnimation(CardImage.getLeft(),X,CardImage.getTop()
          ,Y);
          anim.setFillAfter(true);
          anim.setDuration(1000);
          CardImage.startAnimation(anim);
          }   
          return true;
         }
        });

它刚刚与以下代码一起使用。

public class TestTouch extends Activity implements View.OnTouchListener{    
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ImageView  iv = new ImageView(this);
    iv.setImageResource(R.drawable.flag); // my image
    iv.setOnTouchListener(this);
    setContentView(iv);
}

public boolean onTouch(View v, MotionEvent event)
{
    System.out.println(event.getAction());
    if(event.getAction() == MotionEvent.ACTION_UP)
    {
        System.out.println("Touch!");
    }    
    return true;
}    
}
