Question

我有一个自定义视图，我将添加到相对布局并添加触摸侦听器自定义视图。问题是onTouchevent没有调用.Plz帮助来自我的实际代码::

的示例代码

ViewGroup base = (ViewGroup)findViewById(R.id.base); //relative layout
base.addView(move);
move.setOnTouchListener(touchListener);
OnTouchListener touchListener = new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            Log.d("onTouch v","="+v);
            if(v instanceof MovingView) {
                return false;
            }
            else 
                return true;
        }


    public boolean onTouchEvent(MotionEvent event) {
        int x = (int)event.getX();
            int y = (int)event.getY();


}
};// close listener

首先，在初始化之前设置侦听器（它为null）。试试这个：

ViewGroup base = (ViewGroup)findViewById(R.id.base); //relative layout
base.addView(move);

OnTouchListener touchListener = new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            Log.d("onTouch v","="+v);
            if(v instanceof MovingView) {
                return false;
            }
            else 
                return true;
        }


    public boolean onTouchEvent(MotionEvent event) {
        int x = (int)event.getX();
            int y = (int)event.getY();


}
};// close listener

move.setOnTouchListener(touchListener);

其次，请注意：

调用onTouchEvent（）方法当触摸屏事件未被任何视图处理时它“。

未调用TouchListener onTouchEvent
