Material Design兼容性控件的使用(三)_untreatedlistsrl.setonrefreshlistener-优快云博客

本文介绍如何使用 AppCompat-V7 库中的兼容控件来确保 Android 应用在不同版本和 ROM 间保持一致的用户体验。涵盖 AlertDialog、SwipeRefreshLayout、PopupWindow 等组件的使用方法，并提供代码示例。

在Material Design中，尤其是在appcompat-V7里面有很多为兼容而生的控件这样就可以做到高低版本和不同的ROM之间体验一致！还可以配合appcompat的主题使用达到体验一致性

例如：

1.android.support.v7.app.AlertDialog
2.进度条样式设置
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
3.SwipeRefreshLayout下拉刷新
4.PopupWindow
ListPopupWindow
PopupMenu
....
5.android.support.v7.widget.LinearLayoutCompat

好了！开始上代码

首先引入依赖：

 compile 'com.android.support:appcompat-v7:23.4.0'

activity_main.xml:
