ScrollView not work in ViewPager sliding Issue

 

This paper describes how to solve ViewPager in ScrollView slide often fail, not the normal sliding problem .

 

solution need only close to horizontal scrolling ScrollView does not handle events by his son View (ie, where the ViewPager) treatment can rewrite ScrollView's onInterceptTouchEvent function, as follows:

 

  

   

     [java]      view plain      copy    

  

  

   
1. package cc.newnews.view;
   
   
3. import android.content.Context;
   
4. import android.util.AttributeSet;
   
5. import android.view.GestureDetector;
   
6. import android.view.GestureDetector.SimpleOnGestureListener;
   
7. import android.view.MotionEvent;
   
8. import android.widget.ScrollView;
   
   
10. public class VerticalScrollView extends ScrollView {
   
   
12. private GestureDetector mGestureDetector;
   
   
14. public VerticalScrollView (Context context, AttributeSet attrs) { ;
   
15. super (context, attrs) ;
   
16. mGestureDetector = new GestureDetector (context, ; new YScrollDetector ());
   
17. }
   
   
19. @ Override
   
20. public boolean < span> onInterceptTouchEvent (MotionEvent ev) {
   
21. return < span class = "keyword"> super . onInterceptTouchEvent (ev)
   
22. && mGestureDetector.onTouchEvent (ev) ;
   
23. }
   
   
25. class YScrollDetector extends SimpleOnGestureListener {
   
   
27. @ Override
   
28. public boolean onScroll (MotionEvent e1, MotionEvent e2,
   
29. float distanceX, float distanceY) {
   
30. / **
   
31. * If we closer to horizontal scrolling, returns false, so the child views to deal with it
   
32. * / ;
   
33. return (Math.abs (distanceY)> Math.abs (distanceX));
   
34. }
   
35. }
   
36. }
  

 

 

 

then changed ScrollView xml in that package. rewritten ScrollView class name) can be.

 

This method is also applicable to other View ListView in ScrollView not scrolling.
