SupportMapFragment - 二進制xml文件行＃2：錯誤充氣類片段

Question

我有一個主類繼承FragmentActivty和CustomMapFragment，它擴展了SupportMapFragment，當我將這個customMapFragment調用到FragmentActivity中時，我在logCat中看到這個錯誤。

logcat的結果：

MainActivity：

public class MainActivity extends FragmentActivity { 


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

      ... 

    CustomMapFragment fragment = new CustomMapFragment (getApplicationContext(),this); 
     getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit(); 

      ...  
} 

CustomMapFragment：

public class CustomMapFragment extends SupportMapFragment implements ConnectionCallbacks,OnConnectionFailedListener,LocationListener { 

private LocationClient locationClient; 
private LocationRequest locationRequest; 
private GoogleMap map; 
FragmentActivity activity; 
private Context context; 
View view; 

public CustomMapFragment (Context context,FragmentActivity activity){ 
    this.context = context; 
    this.activity = activity; 
} 

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

    super.onCreateView(inflater, container, savedInstanceState); 

    try { 
     view = inflater.inflate(R.layout.map_layout, container,false); 


     SupportMapFragment suppFragManager = (SupportMapFragment)activity.getSupportFragmentManager().findFragmentById(R.id.map); 
     map = suppFragManager.getMap(); 

     locationClient = new LocationClient(context,this,this); 

     locationRequest = LocationRequest.create(); 
     locationRequest.setInterval(9000); 
     locationRequest.setFastestInterval(900); 
     locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 

     return view; 
    } catch (Exception e) { 
     Log.d("ERROR", e.getMessage()); 
     e.printStackTrace(); 
    } 

    return null; 

} 

... 

map_layout：

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.SupportMapFragment" />

的AndroidManifest.xml：

<uses-sdk

    <meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="***" /> 

    ... 

</application> 

注：我用android.support.v4 LIB在這個類

Answer 1

public class CustomMapFragment extends SupportMapFragment 

所以，CustomMapFragment是SupportMapFragment ...

view = inflater.inflate(R.layout.map_layout, container,false); 

。 ..其中你試圖膨脹另一個SupportMapFragment。

這將無法正常工作。

要麼已經CustomMapFragment延長SupportMapFragment（並刪除其onCreateView()加map_layout.xml）或使用map_layout.xml。不要這樣做。

Answer 2

在你的情況下，一切是完美的只是檢查是否在清單文件

添加了兩個關鍵如果一切沃金同谷歌的代碼，那麼請查一下我的情況下，清單文件我添加地理鍵和地圖密鑰，該密鑰爲什麼發生異常時，

注意 - 不要在清單文件中刪除地圖項中添加兩個鍵

meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="@string/google_maps_key"/> 

以上代碼，並且添加此代碼。

<meta-data 
     android:name="com.google.android.geo.API_KEY" 
     android:value="@string/auto_location"/> 

<meta-data 
     android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version"/>
