Setting place type filters for PlaceAutocomplete

suggest change

In some scenarios, we might want to narrow down the results being shown by PlaceAutocomplete to a specific country or maybe to show only Regions. This can be achieved by setting an AutocompleteFilter on the intent. For example, if I want to look only for places of type REGION and only belonging to India, I would do the following:

MainActivity.java

public class MainActivity extends AppComatActivity {
    
    private static final int PLACE_AUTOCOMPLETE_REQUEST_CODE = 1;
    private TextView selectedPlace;
    
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        selectedPlace = (TextView) findViewById(R.id.selected_place);
        try {
            AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                    .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS)
                    .setCountry("IN")
                    .build();

            Intent intent =
                    new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                            .setFilter(typeFilter)
                            .build(this);
            startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

        } catch (GooglePlayServicesRepairableException
                | GooglePlayServicesNotAvailableException e) {
            e.printStackTrace();
        }
}

protected void onActivityResult(int requestCode,
                                int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        final Place place = PlacePicker.getPlace(this, data);
        selectedPlace.setText(place.getName().toString().toUpperCase());
    } else {
        Toast.makeText(MainActivity.this, "Could not get location.", Toast.LENGTH_SHORT).show();
    }
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/selected_place"/>

</LinearLayout>

The PlaceAutocomplete will launch automatically and you can then select a place from the results which will only be of the type REGION and will only belong to the specified country. The intent can also be launched at the click of a button.

Found a mistake? Have a question or improvement idea? Let me know.
