[Android] ScrollView embedded ViewPager, ViewPager sliding problems

When you switch on the sliding ViewPager must remain completely horizontal sliding . Should the sliding direction of the sliding occurs when tilted ScrollView the scroll event is triggered , and the sliding ViewPager will terminate and change back to the original look .

How can I make when sliding in ViewPager ScrollView not scroll .

ScrollView tried rewriting the onTouchEvent, but to no avail.
------ Solution ---------------------------------------- ----
the problem I have encountered , could not find a good way , and finally I put ScrollView deleted , if we want to keep it proposed to achieve

already own implementation , the need to rewrite ScrollView, the following is code

  package com.zp365.view;
  
  import android.content.Context;
  import android.util.AttributeSet;
  import android.view.GestureDetector;
  import android.view.GestureDetector.SimpleOnGestureListener;
  import android.view.MotionEvent;
  import android.view.View;
  import android.widget.ScrollView;
  
  /**
   * 解决ScrollView嵌套ViewPager出现的滑动冲突问题
   */
  public class ScrollView1 extends ScrollView {
  	private boolean canScroll;
  
  	private GestureDetector mGestureDetector;
  	View.OnTouchListener mGestureListener;
  
  	public ScrollView1(Context context, AttributeSet attrs) {
  		super(context, attrs);
  		mGestureDetector = new GestureDetector(new YScrollDetector());
  		canScroll = true;
  	}
  	@Override
  	public boolean onInterceptTouchEvent(MotionEvent ev) {
  		if(ev.getAction() == MotionEvent.ACTION_UP)
  			canScroll = true;
  		return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
  	}
  
  	class YScrollDetector extends SimpleOnGestureListener {
  		@Override
  		public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
  			if(canScroll)
  				if (Math.abs(distanceY) >= Math.abs(distanceX))
  					canScroll = true;
  				else
  					canScroll = false;
  			return canScroll;
  		}
  	}
  }
  

ScrollView with this custom ScrollView on the line instead of the original

------ eference --------------------------------------- < br> If yes tgyhrfuj741 said, although can be achieved, but sliding around scrollview not useful , I am now the main problem is that there is a lateral view of the sliding scrollview subview has a slide up and down scrollview, embedded in a child view viewpager, but viewpager sliding around events and outermost sliding around scrollview event of a conflict , ask how to solve
