在活动全屏幕的背景图像 [英] Full screen background image in an activity

问题描述

我看到，使用全屏图像作为背景多种应用。 这是一个例子：

I see many applications that use a full-screen image as background. This is an example:

我想用这个项目中，我发现，到目前为止，做到这一点是使用图像具有大尺寸，把它放在一个的ImageView 和使用安卓adjustViewBounds =真正的来调整页边距

I want to use this in a project, the best way I've found so far to do this is to use an image with a large size, put it in a ImageView and use android: adjustViewBounds="true" to adjust the margins

的问题是，如果具有非常高的分辨率的屏幕，所述图像属于短

The problem is that if a screen with a very high resolution, the image falls short.

我想到了另一种选择是使用图像中的的FrameLayout ，与 match_parent 在宽度和高度作为背景...这绵延的形象，但我觉得结果不是很好。

Another option I thought of is to use the image in a FrameLayout, with match_parent in width and height as background... this stretches the image, but I think the result is not very good.

我可以问你会怎么做呢？

I can ask how would you do it?
