java - 更改 Google Maps API 的 "My location"按钮的位置

Question

我正在使用 Google Maps Android API v2，我需要一种方法来确定“我的位置”按钮的位置。

我得到这样的“我的位置”按钮:

GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
final GoogleMap map = ((SupportMapFragment) getSupportFragmentManager()
        .findFragmentById(R.id.map)).getMap();

// This gets the button
map.setMyLocationEnabled(true);

Answer 1

您可以获取“我的位置”按钮并移动它，例如:

public class MapFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View mapView = super.onCreateView(inflater, container, savedInstanceState);   

    // Get the button view 
    View locationButton = ((View) mapView.findViewById(1).getParent()).findViewById(2);

    // and next place it, for exemple, on bottom right (as Google Maps app)
    RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
    // position on right bottom
    rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
    rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
    rlp.setMargins(0, 0, 30, 30);
    }
}
