>为surfaceview添加父视图组,将背景颜色设置为此视图组而不是surfaceview;

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/holo_blue_dark">

    <com.example.surfacetest.MySurface
        android:id="@+id/surface"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

>为SurfaceView实例添加以下内容;

surfaceView.setZOrderOnTop(true);
surfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);

现在你得到你想要的背景颜色,而surfaceview是tanslucent.
