調用AndEngine查看簡單活動

我有andEngine surfaceview及其對應的活動。現在我想在簡單的活動中稱這個andengine View爲例，我不想通過intent調用andEngine活動。就像Custome查看調用AndEngine查看簡單活動

**XML View:** 

<?xml version="1.0" encoding="UTF-8"?>

**MySimple Activity:(Main Launcher Activity)** 



public class TestActivity extends Activity { 
/** Called when the activity is first created. */

super.onCreate(savedInstanceState); 
this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.xmlLayout); 

} 
}

logcat的觀點：

我想這一點，但它給錯誤：

不要延長SimpleBaseGameActivity。用LayoutGameActivity類來擴展。實現以下方法：

@Override 
protected int getLayoutID() 
{ 
    return R.layout.my_layout; 
} 

@Override 
protected int getRenderSurfaceViewID() 
{ 
    return R.id.xml_rendersurfaceview; 
}

my_layout內容：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

    <org.anddev.andengine.opengl.view.RenderSurfaceView 
    android:id="@+id/xml_rendersurfaceview" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"/> 

    <RelativeLayout 
    android:layout_width="fill_parent" 
    android:layout_height="50dip" 
    android:layout_alignParentTop="true"> 


    </RelativeLayout> 

</RelativeLayout>

，並在此佈局添加您的版面內容。
