Disable vertical scroll when user scrolling horizontally in android

问题

I have a vertical custom list and each item of vertical list contains a horizontal list-view. When I scroll horizontally then list also moves little vertically. Which makes it less user friendly. Can I disable vertical scrolling while scrolling horizontally. I am using

<com.devsmart.android.ui.HorizontalListView
        android:id="@+id/hlistview"
        android:layout_width="match_parent"
        android:layout_height="155dp"
        android:layout_margin="6dp"
        android:background="#fff"
        android:fitsSystemWindows="true"
    />

for horizontal list view

The idea is to disable the parent listview to intercept touch event. This might work :

HorizontalListView hv = (HorizontalListView)findViewById(R.id.hlistview);  
    hv.setOnTouchListener(new ListView.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int action = event.getAction();
                switch (action) {
                case MotionEvent.ACTION_DOWN:
                    // Disallow ListView to intercept touch events.
                    v.getParent().requestDisallowInterceptTouchEvent(true);
                    break;

                case MotionEvent.ACTION_UP:
                    // Allow ListView to intercept touch events.
                    v.getParent().requestDisallowInterceptTouchEvent(false);
                    break;
                }

                // Handle HorizontalScrollView touch events.
                v.onTouchEvent(event);
                return true;
            }
        });
