android 使用surfaceview 内存泄漏，大神帮忙看一哈

xml：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/loading_bg"
    android:orientation="vertical">    <FrameLayout
        android:id="@+id/lLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@drawable/loading_bg"
        android:orientation="vertical">        <com.xxx.xxx.app.web.MySurfaceView 
            android:id="@+id/sv"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">
        </com.xxx.xxx.app.web.MySurfaceView >
......
java 代码：              
         .....                   mSurfaceView = (MySurfaceView) mMainView.findViewById(R.id.sv);
          SurfaceHolder sh = mSurfaceView.getHolder();
          sh.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
          sh.addCallback(this);
.....          
MySurfaceViewpublic class MySurfaceView extends SurfaceView {
private  static  final  String TAG ="BesTVSurfaceView";
public MySurfaceView (Context context) {
super(context);
} public MySurfaceView (Context context, AttributeSet attrs) {
super(context, attrs);
}

public MySurfaceView (Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

private void initView() {
Log.d(TAG,"initView");
}
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
initView();
}
}
