Example Analysis of FrameLayout in Android

This article will explain in detail the example analysis of FrameLayout in Android. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Overview

FrameLayout layouts components in a cascading manner: only one of them can be displayed at a time. Similar to playing cards, only the top card can be seen when stacked together. FrameLayout provides a XML configuration property for components laid out in it: Android:layout_gravity. With this property, components laid out in FrameLayout can specify their center of gravity in the container, such as left, right, and so on, and all controls are displayed in the upper left corner of the screen by default.

Properties defined globally by FrameLayout
