It wasn't working well for me. I changed it and now it works smoothly. If anyone interested.
public class ScrollViewForNesting extends ScrollView { private final int DIRECTION_VERTICAL = 0; private final int DIRECTION_HORIZONTAL = 1; private final int DIRECTION_NO_VALUE = -1; private final int mTouchSlop; private int mGestureDirection; private float mDistanceX; private float mDistanceY; private float mLastX; private float mLastY; public ScrollViewForNesting(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); final ViewConfiguration configuration = ViewConfiguration.get(context); mTouchSlop = configuration.getScaledTouchSlop(); } public ScrollViewForNesting(Context context, AttributeSet attrs) { this(context, attrs,0); } public ScrollViewForNesting(Context context) { this(context,null); } @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: mDistanceY = mDistanceX = 0f; mLastX = ev.getX(); mLastY = ev.getY(); mGestureDirection = DIRECTION_NO_VALUE; break; case MotionEvent.ACTION_MOVE: final float curX = ev.getX(); final float curY = ev.getY(); mDistanceX += Math.abs(curX - mLastX); mDistanceY += Math.abs(curY - mLastY); mLastX = curX; mLastY = curY; break; } return super.onInterceptTouchEvent(ev) && shouldIntercept(); } private boolean shouldIntercept(){ if((mDistanceY > mTouchSlop || mDistanceX > mTouchSlop) && mGestureDirection == DIRECTION_NO_VALUE){ if(Math.abs(mDistanceY) > Math.abs(mDistanceX)){ mGestureDirection = DIRECTION_VERTICAL; } else{ mGestureDirection = DIRECTION_HORIZONTAL; } } if(mGestureDirection == DIRECTION_VERTICAL){ return true; } else{ return false; } } }
