ListView +HorizontalScrollView OnItem 冲突

在Item 的根布局中加上这个属性设置 beforeDescendants

 `android:descendantFocusabilitybeforeDescendants：viewgroup会优先其子类控件而获取到焦点afterDescendants：viewgroup只有当其子类控件不需要获取焦点时才获取焦点blocksDescendants：viewgroup会覆盖子类控件而直接获得焦点`

以上可能还解决不了去创一个自己的HorzontalScroollView 重写里面的 onTouchEvent 方法自己处理 onTouch 事件

public class MyHorizontalScrollView extends HorizontalScrollView{    public MyHorizontalScrollView(Context context) {        super(context);    }    public MyHorizontalScrollView(Context context, AttributeSet attrs) {        super(context, attrs);    }    float xDown = 0;    float yDown = 0;    float xUp = 0;    float yUp = 0;    @Override    public boolean onTouchEvent(MotionEvent ev) {        Log.e("AAA-->>", "onTouchEvent: "+ev.getAction()+ev.getX() +"--"+ev.getY() );        switch (ev.getAction()){            case MotionEvent.ACTION_DOWN:                xDown = ev.getX();                yDown = ev.getY();                break;            case MotionEvent.ACTION_MOVE:                break;            case MotionEvent.ACTION_UP:                xUp = ev.getX();                yUp = ev.getY();                Log.e("AAA-->>Math-->", "onTouchEvent: "+Math.abs((xDown-xUp)) +"--"+Math.abs((yDown-yUp)) );                if (Math.abs((xDown-xUp)) <=20  && Math.abs((yDown-yUp)) <=20){                    Log.e("AA ea gag ", "onTouchEvent: " );                    onClickMyScrollListener.onClickMyScrollListener();                    return true;                }                break;        }        return super.onTouchEvent(ev);    }    public interface OnClickMyScrollListener{        void onClickMyScrollListener();    }    private OnClickMyScrollListener onClickMyScrollListener;    public void setOnClickMyScrollListener(OnClickMyScrollListener onClickMyScrollListener) {        this.onClickMyScrollListener = onClickMyScrollListener;    }}

其他类似冲突也可以重写 OnTouch 方法
