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+";"); 
     
   } 
  });
