沉浸式状态栏 设置状态栏颜色
方式一：使用系统API
这个特性是andorid4.4支持的，最少要api19才可以使用。
1、隐藏标题栏等
在代码中设置
requestWindowFeature(Window.FEATURE_NO_TITLE);//隐藏标题栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);//窗口透明的状态栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);//
窗口透明的
导航栏
setContentView(R.layout.activity_main);
或者在整个应用的样式中设置
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">style>
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowNoTitle">trueitem>
<item name="android:windowTranslucentStatus">trueitem>
<item name="android:windowTranslucentNavigation">trueitem>
style>
resources>
此时效果为
2、在布局中第一个元素中添加如下属性
android:clipToPadding="true"
android:fitsSystemWindows="true"
属性的含义：
- clipToPadding：控件的绘制区域是否在padding里面，值为true时绘制的区域就包括padding区域；
- android:fitsSystemWindows：具体的作用就是你的contentview是否忽略actionbar、title、屏幕的底部虚拟按键，将整个屏幕当作可用的空间。正常情况，contentview可用的空间是去除了actionbar、title、底部按键的空间后剩余的可用区域，这个属性设置为true，则忽略，false则不忽略。简单来说，设置为true后，你的可用屏幕是整个屏幕，所以要注意，你的第一个控件是从状态栏那里开始布局的。
此时效果为
方式二：使用开源框架[废弃了]
