Handle nested scrollbar in Android

You have to just replace your <ScrollView ></ScrollView> in layout XML file with this Custom ScrollView like <com.tmd.utils.VerticalScrollview > </com.tmd.utils.VerticalScrollview >

 package com.tmd.utils;  
 import android.content.Context;  
 import android.util.AttributeSet;  
 import android.util.Log;  
 import android.view.MotionEvent;  
 import android.widget.ScrollView;  
 public class VerticalScrollview extends ScrollView{  
   public VerticalScrollview(Context context) {  
     super(context);  
   }  
    public VerticalScrollview(Context context, AttributeSet attrs) {  
       super(context, attrs);  
     }  
     public VerticalScrollview(Context context, AttributeSet attrs, int defStyle) {  
       super(context, attrs, defStyle);  
     }  
   @Override  
   public boolean onInterceptTouchEvent(MotionEvent ev) {  
     final int action = ev.getAction();  
     switch (action)  
     {  
       case MotionEvent.ACTION_DOWN:  
           Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );  
           super.onTouchEvent(ev);  
           break;  
       case MotionEvent.ACTION_MOVE:  
           return false; // redirect MotionEvents to ourself  
       case MotionEvent.ACTION_CANCEL:  
           Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );  
           super.onTouchEvent(ev);  
           break;  
       case MotionEvent.ACTION_UP:  
           Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );  
           return false;  
       default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;  
     }  
     return false;  
   }  
   @Override  
   public boolean onTouchEvent(MotionEvent ev) {  
     super.onTouchEvent(ev);  
     Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );  
      return true;  
   }  
 }
