refreshListItem.java

    /**
     * Update single item inside {@link ListView}.
     * @param target {@link Object} object to update view.
     */
    private void refreshListItem(Object target){
        ListView list = getListView();
        // Find position of the first visible row
        int start = list.getFirstVisiblePosition();
        // Find position of the last visible row
        int end = list.getLastVisiblePosition();
        for(int i=start, j=end;i<=j;i++) {
            if (target == list.getItemAtPosition(i)) {
                // Target view to process
                View view = list.getChildAt(i - start);

                // Calling getView will redraw the whole item
                View v = list.getAdapter().getView(i, view, list);

                // Call requestLayout to update only certain item in the view
                view.findViewById(R.id.image).requestLayout();
                break;
            }
        }
