Used when it is wanted to set selection listview with animation.

SmoothScroll.java

 public void smootScroolListview() {

        int duration = 300;//ms
        int position = mListView.getFirstVisiblePosition();
        int getHight = mListView.getHeight();

        mListView.smoothScrollBy( ( ( getHight * position ) * -1 ), duration * 2 );
        this.mListView.postDelayed( new Runnable() {
            @Override
            public void run() {
                mListView.smoothScrollBy( 0, 0 );
                mListView.setSelection( 0 );
            }
        }, duration );

    }
