设置SurfaceView的背景图像 [英] Set the Background Image of a SurfaceView

问题描述

有没有一种方法来设置一个SurfaceView的背景图片？是否必须在XML做或者我可以做这一切在Java中 - 我已经得到的东西，看起来像这样在我的构造函数：

Is there a way to set the background image of a SurfaceView? Does it have to be done in xml or can I do it all in Java - I've got something that looks like this in my constructor:

Drawable sky = (getResources().getDrawable(R.drawable.sky));
    this.setBackgroundDrawable(sky);

但它仍然没有显示任何东西。

But it still doesn't show anything.

推荐答案

您不能设置一个SurfaceView背景绘制。你必须绘制背景在表面上你自己。

You cannot set a background drawable on a SurfaceView. You'll have to draw the background onto the surface yourself.
