这是我启用位置按钮的方式,以便可以在地图上单击它:
map.setMyLocationEnabled(true);
我的问题是,如何找到此按钮并将其存储在变量中,以便根据我的应用程序的逻辑显示或不显示它?谢谢!

您可以通过MapFragment
根视图上的findViewWithTag("GoogleMapMyLocationButton")
来获取它。使用这样的代码:
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
...
private GoogleMap mGoogleMap;
private MapFragment mMapFragment;
private View mMyLocationButtonView = null;
...
@Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
if (locationPermission != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String [] {Manifest.permission.ACCESS_FINE_LOCATION}, LOCATION_PERMISSION_REQUEST_CODE);
} else {
mGoogleMap.setMyLocationEnabled(true);
mGoogleMap.getUiSettings().setMyLocationButtonEnabled(true);
mMyLocationButtonView = mMapFragment.getView().findViewWithTag("GoogleMapMyLocationButton");
mMyLocationButtonView.setBackgroundColor(Color.GREEN);
}
}
}
}
您会得到类似的东西:

您可以通过调用UiSettings.setMyLocationButtonEnabled(false)
来阻止“我的位置”按钮出现。
