Android 在模拟器中测试触摸功能

我尝试为android开发一个应用程序。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函数？我试图用鼠标拖动图像开关，但什么也没发生

谢谢你的帮助

尝试此代码（注意：未测试）

它刚刚使用了以下代码

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;
}    
}

您的活动是否实现了onTouchListener？

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;
}    
}
