ListExpandableView

ListExpandableView:

Implementation:

listview_row.xml:

• In listview_row xml file we have two relative layout. 1.- rel_top_layout and 2. - rel_bottom_layout
• ByDefault bottom layout visibility is gone and top layout is visible.

ListAdapter:

• we handle visibility control and animation in this adapter class.
• In below code we are checking any view clickable previously or not, if clickable than we display bottom view for that particular position.

if(stringArrayList.get(position).isDisplayView()){
          viewHolder.relBottomLayout.setVisibility(View.VISIBLE);
            animation = AnimationUtils.loadAnimation(mContext,R.anim.grow_from_bottom);
            viewHolder.relBottomLayout.startAnimation(animation);
        } else {
            viewHolder.relBottomLayout.setVisibility(View.GONE);
        }

• Below code is use for hide and provide animation to bottom view

stringArrayList.get(position).setDisplayView(false);
               animation = AnimationUtils.loadAnimation(mContext,R.anim.slide_out_down);
               viewHolder.relBottomLayout.startAnimation(animation);
                    {
                       @Override
                        public void onAnimationStart(Animation animation) {
                        // TODO Auto-generated method stub
                    }
                       @Override

                        public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
                        public void onAnimationEnd(Animation animation) {
viewHolder.relBottomLayout.setVisibility(View.GONE);
}
               });
