我正在尝试在 Google 地图中添加此按钮。单击后，它将显示该地点的位置。但是，当我运行它时，它给了我一个强制关闭错误。

我现在要让它工作的按钮是“CITY”按钮的另外两个，我还没有设置它。

这是我的 logcat 错误。

这是我的编码。

MainActivity.java

public class MainActivity extends  FragmentActivity  {

    private final LatLng LOCATION_BURNABY = new LatLng(49.27645, -122.917587);
    private final LatLng LOCATION_SURREY = new LatLng(49.187500, -122.849000);

    private GoogleMap map;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
    }

    public void onClick_City(View v){
        CameraUpdate update = CameraUpdateFactory.newLatLng(LOCATION_BURNABY);
        map.animateCamera(update);
    }

    public void onClick_Burnaby(View v){

    }

    public void onClick_Surrey(View v){

    }
}

你应该使用getSupportFragmentManager()

SupportMapFragment fm = (SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map);
map = fm.getMap();
