谷歌地图不能在片段视图中工作

Question

我试图在我的片段视图中显示一个mapview，我在谷歌控制台devoloper中创建密钥，我在我的电脑和所有athers步骤中生成密钥，但是我alwys得到了w格伦斯科伦，我该如何解决这个问题。

代码：

家fragment.java

package com.malek.sos.sosdepanage; 


import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

import com.google.android.gms.common.GooglePlayServicesNotAvailableException; 
import com.google.android.gms.maps.CameraUpdate; 
import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.MapView; 
import com.google.android.gms.maps.MapsInitializer; 
import com.google.android.gms.maps.model.LatLng; 


/** 
* A simple {@link Fragment} subclass. 
*/ 
public class HomeFragment extends Fragment { 

    MapView mapView; 
    GoogleMap map; 
    public HomeFragment() { 
     // Required empty public constructor 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View v = inflater.inflate(R.layout.fragment_home, container, false); 

     mapView = (MapView) v.findViewById(R.id.mapview); 
     mapView.onCreate(savedInstanceState); 
     map = mapView.getMap(); 
     /* map.getUiSettings().setMyLocationButtonEnabled(false); 
     map.setMyLocationEnabled(true); 
*/ 
     // Needs to call MapsInitializer before doing any CameraUpdateFactory calls 

      MapsInitializer.initialize(this.getActivity()); 


     // Updates the location and zoom of the MapView 
     /* CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10); 
     map.animateCamera(cameraUpdate);*/ 
     return v; 
    } 

} 

片段家居布置

<FrameLayout 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@color/white" 
    tools:context="com.malek.sos.sosdepanage.HomeFragment" 
    android:name="com.google.android.gms.maps.SupportMapFragment" > 

    <!-- TODO: Update blank fragment layout --> 
    <com.google.android.gms.maps.MapView 
     android:id="@+id/mapview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" /> 

</FrameLayout> 

的manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

      </intent-filter> 
     </activity> 
    </application> 

</manifest> 

Answer 1

活动类

public class MapActivity implements OnMapReadyCallback { 

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

     initMap(); 
    } 

    private void initMap() { 
     MapFragment map = (MapFragment) getFragmentManager().findFragmentById(R.id.map); 
     map.getMapAsync(this); 
    } 

    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     // get latitude & longitude from somewhere 
     googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude))); 
    } 

} 

布局xml文件

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <fragment 
     android:id="@+id/map" 
     class="com.google.android.gms.maps.MapFragment" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     map:cameraTargetLat="-38.004635" 
     map:cameraTargetLng="-57.541511" 
     map:cameraZoom="14" 
     map:mapType="normal" 
     map:uiCompass="false" 
     map:uiRotateGestures="false" 
     map:uiScrollGestures="false" 
     map:uiTiltGestures="false" 
     map:uiZoomControls="false" 
     map:uiZoomGestures="false" 
     tools:ignore="MissingPrefix" /> 

</LinearLayout> 

重要的部分是：

• 实施OnMapReadyCallback
• 片段中的XML定义
类属性
