Allow user to search and scroll to the ListView

Question

I have a custom ListView set up in my app.

I am not sure how or if it's possible to do but I want to know how can I have the Android search icon to allow user to search within the ListView. So as the search becomes relevant, the ListView scrolls to that position and changes the background drawable.

I am looking to implement the search inside the ActionBar like this:

You need to implement the content provider component for your application. The "private" content provider will allow you to do "custom search" like you desire. As per documentation:

However, you do need your own provider to provide custom search suggestions in your own application.

The NotePad example can provide you with a good starting point on implementing a "private" content provider. By "private", i mean that you are not sharing the ListView data with any other app or process running on your device or remotely.

1. You need to implement a Filter simply by implements Filter to your ListView adapter.
2. Write how you will filter your results inside performFiltering(CharSequence constraint) method.
3. All you need is to make a call inside your SearchView query text listeners.
4. Invalidate the ListView with filtered results. Or get position of relevant item inside the Adapter data, and scroll using mListView.smoothScrollToPosition(int position)
