Android自定义ScrollView使用自定义监听

@Override public boolean onTouchEvent(MotionEvent ev) {  switch (ev.getAction()) {  case MotionEvent.ACTION_MOVE:   //触发监听   onSlideListener.onSlide((int)ev.getX(),(int)ev.getY());   break;   }  return super.onTouchEvent(ev); }  private OnSlideListener onSlideListener;   public void setOnSlideListener(OnSlideListener onSlideListener){  this.onSlideListener=onSlideListener; }  //自定义接口 public interface OnSlideListener{  void onSlide(int x,int y); } 

myScrollView.setOnSlideListener(new OnSlideListener() {        @Override    public void onSlide(int x, int y) {          ToastUtils.showToast(MainActivity.this, "X轴坐标是："+x+";Y轴坐标是："+y+";");         }   });
