Android: ListView with Filterable List and Animation

Adding demo here to create ListView with Filterable List.

• ListView
• Filterable Interface
• Animation ListView

For adding filterable ListView we have to implement Filterable interface in our Adapter class.

And define getFilter() method of this interface.

For Example:

@Override

public Filter getFilter() {

return new Filter() {

@SuppressWarnings("unchecked")

@Override

protected void publishResults(CharSequence constraint, FilterResults results) {

/*

*Notify listview to populate new list after filtering

*/

notifyDataSetChanged();

}

/* (non-Javadoc)

* constraint : String to filter result

* return  FilterResults to populate on listview

*/

@Override

protected FilterResults performFiltering(CharSequence constraint) {

/*

*Here we will get string to filter result from current list.

*We can create new result data to populate on listview. 

*/

                  return resultData;

}

};

}

For adding animation into ListView we have to create animation xml and put it into anim folder inside res directory 

Now we can add this animation into ListView using below code:

listView.setAnimation(AnimationUtils.loadAnimation(LauncherActivity.this, R.anim.alpha));

For detail download example and see inline comment.
