Question

我在我的项目中使用NavigationDrawer并且我正在实施Google maps，但由于getSupportFragmentManager()我无法做到这一点，它始终给出错误：

方法getSupportFragmentManager()未定义类型MapView。

这是代码：

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

import android.annotation.SuppressLint;
import android.app.Fragment;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

@SuppressLint("NewApi")
public class MapView extends Fragment {


    private Context context = getActivity();

    public MapView(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.map_view, container, false);

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

        int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
        Log.e("Maps", "Result int value::" + result);
        switch (result) {
        case ConnectionResult.SUCCESS:
            Log.e("Maps", "RESULT:: SUCCESS");          
            break;

        case ConnectionResult.DEVELOPER_ERROR:
            Log.e("Maps", "RESULT:: DE");           
            break;

        case ConnectionResult.INTERNAL_ERROR:
            Log.e("Maps", "RESULT:: IE");           
            break;

        case ConnectionResult.INVALID_ACCOUNT:
            Log.e("Maps", "RESULT:: IA");           
            break;

        case ConnectionResult.NETWORK_ERROR:
            Log.e("Maps", "RESULT:: NE");           
            break;

        case ConnectionResult.RESOLUTION_REQUIRED:
            Log.e("Maps", "RESULT:: RR");           
            break;

        case ConnectionResult.SERVICE_DISABLED:
            Log.e("Maps", "RESULT:: SD");           
            break;

        case ConnectionResult.SERVICE_INVALID:
            Log.e("Maps", "RESULT:: SI");           
            break;

        case ConnectionResult.SERVICE_MISSING:
            Log.e("Maps", "RESULT:: SM");           
            break;
        case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
            Log.e("Maps", "RESULT:: SVUR");         
            break;
        case ConnectionResult.SIGN_IN_REQUIRED:
            Log.e("Maps", "RESULT:: SIR");          
            break;      

        default:
            break;
        }
        gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        gMap.setMyLocationEnabled(true);
        Log.e("Maps", "------EOC-------");

        return rootView;
    }

}

Answer 1

import fragment from android.support.v4.app.Fragment;
and just change 

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

    to 

    GoogleMap gMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

在Fragment中调用谷歌地图
