Android的谷歌地圖V2所致com.google.android.gms.maps.SupportMapFragment不能轉換到android.app.Fragment

我有這個在我的課Android的谷歌地圖V2所致com.google.android.gms.maps.SupportMapFragment不能轉換到android.app.Fragment

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 

import com.coffeeandcookies.ushuaiamovil.R; 

public class LayMapa2 extends FragmentActivity 
{ 
    @Override 
    protected void onCreate(Bundle arg0) 
    { 
     setContentView(R.layout.lay_mapa2); 
     super.onCreate(arg0); 
    } 
}

這在我的XML

<?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" 
    android:name="com.google.android.gms.maps.SupportMapFragment" />

這在我manifiest

<uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="17" /> 

    <uses-feature android:glEsVersion="0x00020000" 
       android:required="true"/>

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

我有谷歌，播放services_lib如圖書館proyect在我的工作區和Android的支持，v4.jar

開關super.onCreate第一，然後的setContentView。

這是因爲super.onCreate調用框架的Activity.onCreate分配膨脹任何佈局所需要的資源。因此，必須在膨脹任何佈局之前調用xml/programmatic。

更改您這樣的代碼：

public class MainActivity extends FragmentActivity { 

    private GoogleMap map; 
    private LatLng ltlng; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

      super.onCreate(savedInstanceState); 

      setContentView(R.layout.activity_main); 

     } 
}

檢查Bhavesh Patadiya的答案，https://stackoverflow.com/a/18227605/2684720

如要擴展FragmentActivity這表明你正在使用支持庫V4與Android的低版本兼容。用xml文件中的SupportMapFragment替換MapFragment。 SupportMapFragment是與Android支持包一起使用的。 MapFragment適用於本地API級別11版本的片段。
