BarUtils是一个栏相关工具类
功能:
1. 设置状态栏颜色
2.为滑动返回界面设置状态栏颜色
3.设置状态栏纯色 不加半透明效果
4.设置状态栏颜色(5.0以下无半透明效果,不建议使用)
5.使状态栏半透明
6.针对根布局是 CoordinatorLayout, 使状态栏半透明
7.设置状态栏全透明
8.使状态栏透明(5.0以上半透明效果,不建议使用)
9.为DrawerLayout 布局设置状态栏变色
10.为DrawerLayout 布局设置状态栏颜色,纯色
11.为DrawerLayout 布局设置状态栏变色
12.为DrawerLayout 布局设置状态栏变色(5.0以下无半透明效果,不建议使用)
13.为 DrawerLayout 布局设置状态栏透明
14.为 DrawerLayout 布局设置状态栏透明(5.0以上半透明效果,不建议使用)
15.为头部是 ImageView 的界面设置状态栏全透明
16.为头部是 ImageView 的界面设置状态栏透明(使用默认透明度)
17.为头部是 ImageView 的界面设置状态栏透明
18.为 fragment 头部是 ImageView 的设置状态栏透明
19.为 fragment 头部是 ImageView 的设置状态栏透明
20.为 fragment 头部是 ImageView 的设置状态栏透明
21.添加半透明矩形条
22.生成一个和状态栏大小相同的彩色矩形条
23.生成一个和状态栏大小相同的半透明矩形条
24.设置根布局参数
25.设置透明
26.使状态栏透明
27.创建半透明矩形 View
28.获取状态栏高度
29.计算状态栏颜色
30.设置透明状态栏(api大于19方可使用)
31.隐藏状态栏
32.判断状态栏是否存在
33. 获取ActionBar高度
34.显示通知栏
35.隐藏通知栏
36.反射唤醒通知栏
