谷歌地图显示完美，googleplayservices 也存在，但我右上角的位置按钮在谷歌地图 api v2 中不起作用，我的 wifi 和 gps 都打开了。请帮助。我正在我的手机上测试它。我不知道为什么它不起作用

mainActivity.java

package com.example.mapexample;

import android.app.Dialog;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.widget.Toast;

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;

public class MainActivity extends FragmentActivity{

    final int RQS_GooglePlayServices = 1;
    private GoogleMap myMap;
    private LocationManager locationManager;


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


         // Do a null check to confirm that we have not already instantiated the map.
        if (myMap == null) {

            myMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
  // Check if we were successful in obtaining the map.
            if (myMap != null) {
                // The Map is verified. It is now safe to manipulate the map.
                setUpMap();
            }
        }

    }


    @Override
     protected void onResume() {
      // TODO Auto-generated method stub
      super.onResume();

      int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

      if (resultCode == ConnectionResult.SUCCESS){
       Toast.makeText(getApplicationContext(), 
         "isGooglePlayServicesAvailable SUCCESS", 
         Toast.LENGTH_LONG).show();
      }else{
       GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices);
      }

     }


    private void setUpMap(){
        myMap.setMyLocationEnabled(true);

    }

}

mainifest 文件在这里具有适当的权限。 主要节日

尝试在位置访问设置中关闭 GPS 卫星。如果已启用但无法到达 GPS，则我的位置按钮会静默失效；通过将其关闭，它显然会强制该功能使用网络提供商。
