    我需要在地图上添加谷歌地图标记的帮助。我希望地图显示我的移动设备的当前位置,并希望它使用标记显示位置。

    现在我的问题是,显示设备当前位置的代码与我之前在另一个项目中使用的代码完全相同,它在那里工作没有问题,但当我在这里使用它时,它会给我带来问题。

    下面是我的代码和Logcat中的信息。

    代码: 

    private void displayLocation() {
    try
    {
        // check if permission are granted
        if (ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        {
            return;
        }
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if(mLastLocation != null)
        {

            final double latitude = mLastLocation.getLatitude();
            final double longitude = mLastLocation.getLongitude();

            // update to the firebase database
            geoFire.setLocation(FirebaseAuth.getInstance().getCurrentUser().getUid(), new GeoLocation(latitude, longitude), new GeoFire.CompletionListener(){
                @Override
                public void onComplete(String key, DatabaseError error) {
                    // add marker to the map
                    if(mUserMarker != null)
                    {
                        mUserMarker.remove(); // removes the already existing marker
                    }

                    mUserMarker = mMap.addMarker(new MarkerOptions()
                            .position(new LatLng(latitude,longitude))
                            .title("You are here"));
                    // move the map camera to the current location of the user
                    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude,longitude),15.0f));

                }
            });
            Log.d("location Updates",String.format("Your location was changed :%f/%f",latitude,longitude));

        }
        else
        {
            Log.d("Location Error","Cannot get your current location");
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }


}

    根据您提供的logcat输出,您需要解决的第一件事是 mMap 变量为空。

    我猜你不是在打电话 displayLocation() 在 onMapReady(...) 回调已启动,或者您的类根本无法处理回调。

    如果您使用的是Google地图片段,基本方法如下:

    在您的 onCreate(...) 方法:

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

    确保类实现 com.google.android.gms.maps.OnMapReadyCallback .

    然后,覆盖 onMapReady(GoogleMap googleMap) 方法并设置 mMap公司 变量 

    @Override
public void onMapReady(GoogleMap googleMap){

mMap = googleMap;

//Do whatever else you need to with the map...
}

    确保您不使用 mMap公司 直到它被设置好,你应该能够添加你的标记,并做其他事情没有问题。
