我想谷歌地图显示用户的位置.我尝试了这段代码,但它在Android 6上无效.

private GoogleMap map;
LocationManager lm;
LocationListener ll;
Location l;

LatLng pos;

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

    lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    ll = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            l = (Location) location;
        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {}

        @Override
        public void onProviderEnabled(String provider) {}

        @Override
        public void onProviderDisabled(String provider) {}
    };

    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.nMap);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    map = …

我想在本机谷歌地图应用程序中实现搜索工具栏.我该怎么做？可能有本地方式来实现此功能？

我制作了一个应用程序,其中我在我的位置显示了带有GPS位置标记的Google地图.此地图位于第一个选项卡上,我还有另外两个选项卡,如下图所示

现在我面临一个问题,即当我从选项卡1移动到选项卡2然后再转到选项卡1时它完美地工作,但是当我移动到选项卡3然后移回选项卡1或选项卡2时,应用程序崩溃并给出以下内容例外情况LogCat:
