Android:为RelativeLayout设置背景图片？

Question

我在运行时下载了一张图片。现在我想将它设置为 RelativeLayout 的背景。可能吗？

Answer 1

查看 setBackgroundDrawable ，或者可能是 createFromPath在 Drawable 类中。

   RelativeLayout rLayout = (RelativeLayout) findViewById (R.id.rLayout);
   Resources res = getResources(); //resource handle
   Drawable drawable = res.getDrawable(R.drawable.newImage); //new Image that was added to the res folder

    rLayout.setBackground(drawable);
