Google maps already has a location button that zooms the camera to the users location. Though I'm assuming that's not what you're looking for

I'm going to describe how to use the android widget SearchView to input text, but you'll need to use Geocoder to find the location from that text.

First, to use the search view, you must declare it in your XML file.

    <SearchView
        android:id="@+id/searchview_map_search"
        android:width="fill_parent"
        android:height="wrap_content" />

This creates a search view bar that expands when a user clicks on it, you can also use an EditText field to allow a user to input a searchable string. I'll continue with SearchView

In your MapFragment or Activity where you will be searching from, set a QueryListener to the searchView

    SearchView searchView = (SearchView) item.getActionView().findViewById(R.id.serchview_map_search);

    searchView.setOnQueryTextListener(new OnQueryTextListener() {

        @Override
        public boolean onQueryTextSubmit(String query) {
            // Do something when user his enter on keyboard
            view.clearFocus();
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            // Do something while user is entering text
            return false;
        }
    });

String query is the input string that the user has typed. You can use that string the then move the camera to the location of the typed string. Doing this though requires another class or system. The easiest way to convert the name of a location to the LatLng coordinates of the location is to use the Geocode class: http://developer.android.com/reference/android/location/Geocoder.html I won't go into that, there are plenty of StackOverflow questions on that topic
