在Android中定义RelativeLayout视图的Z顺序 [英] Defining Z order of views of RelativeLayout in Android

问题描述

我想在 Android 中定义一个 RelativeLayout 的视图的 z 顺序.

I would like to define the z order of the views of a RelativeLayout in Android.

我知道一种方法是调用 bringToFront.

I know one way of doing this is calling bringToFront.

有没有更好的方法来做到这一点?如果我可以在布局 xml 中定义 z 顺序就好了.

Is there are better way of doing this? It would be great if I could define the z order in the layout xml.

推荐答案

最简单的方法就是注意将视图添加到 XML 文件的顺序.在文件中较低意味着在 Z 轴上较高.

The easiest way is simply to pay attention to the order in which the Views are added to your XML file. Lower down in the file means higher up in the Z-axis.

这在此处和此处.(感谢@flightplanner)

This is documented here and here on the Android developer site. (Thanks @flightplanner)
