If you need to provide contacts search functionality in your application, you can do so using SearchView and contact content provider. As user types into search view, you can query contact content provider, get contacts matching the search string and display the results as suggestions dropdown or in ListView.
On clicking one of the search results in suggestion dropdown or list view, you can display contact details. In this tutorial, you can learn how to implement contact search functionality in android.
Read contact content provider and reading and writing data to it article for more information on contact content provider.
To know more about SearchView and how to implement search, read implementing search in android using search view and implementing search dropdown suggestion articles.
