How to restrict to particular city results using Places API android
问题
我有一个需求，如果假设城市是海得拉巴，那么我需要使用地点搜索API仅在搜索时获取海得拉巴的地点。但是我在搜索时只得到了一些地点。如何获取与海得拉巴城市相关的所有地点。请问是否有人可以帮助我。

```java
if (!Places.isInitialized()) {
Places.initialize(getApplicationContext(), "apikey");
}
final AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
getSupportFragmentManager().findFragmentById(R.id.autofill);
autocompleteFragment.setCountry("IN");
final Button closeBtn = dialog.findViewById(R.id.close_btn);
dialog.show();
autocompleteFragment.setLocationRestriction(RectangularBounds.newInstance(
new LatLng(17.387140, 78.491684),
new LatLng(17.440081, 78.348915)));
autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME, Place.Field.ADDRESS, Place.Field.LAT_LNG));
autocompleteFragment.setTypeFilter(TypeFilter.ADDRESS);
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: 获取所选地点的信息。
if (place.getAddress() != null) {
Log.e("Place", "Place: " + place.getName() + " , " + place.getId() + " , " + place.getAddress() + " , " + place.getLatLng());

}
String aa = addresses.get(0).getAddressLine(0);
Log.e("aa:", aa);
String[] ad = aa.split(",");
