我试图让纬度地图的中心和纬度。我使用的片段显示地图就是

I was trying to get latitude and longitude of center of the map. I am using Fragment to show map that is,

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
                                    .findFragmentById(R.id.mapID);
if (fm != null) {
    googleMap = fm.getMap();
}
LatLng loc = googleMap.getCameraPosition().target;

我打印这个禄和我得到的价值为0.0，0.0。我没有得到我要去的地方错了。

I am printing this loc and i am getting value as 0.0, 0.0. I am not getting where i am going wrong.

我试图用 VisibleRegion 也得到纬度地图，甚至是中心没有帮助和经度。

I tried to use VisibleRegion also to get latitude and longitude of center of map but even that did not help.

推荐答案

您所请求的摄像机位置时，地图上还没有装，因此相机指向0.0，0.0。相反，使用这样的：

You are requesting the camera position when the map was not yet loaded, therefore the camera is pointing to 0.0, 0.0. Instead use this:

googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
    @Override
    public void onMapLoaded() {
        Log.e("TAG", googleMap.getCameraPosition().target.toString());
    }
});
