状态栏着色，也就是我们经常听到的沉浸式状态栏，关于沉浸式的称呼网上也有很多吐槽的，这里就不做过多讨论了，以下我们统称状态栏着色，这样我觉得更加容易理解。
从Android4.4开始，才可以实现状态栏着色，并且从5.0开始系统更加完善了这一功能，可直接在主题中设置<item name="colorPrimaryDark">@color/colorPrimaryDark</item>或者getWindow().setStatusBarColor(color)来实现，但毕竟4.4+的机器还有很大的占比，所以就有必要寻求其它的解决方案。
一般通过Android Studio新建项目时就实现了状态栏着色功能，不过只能在API>19的机型上正常显示。下面是通过Android studio新建项目时的默认样式代码：
styles.xml
colors.xml
AndroidManifest.xml
而本文想要实现的效果是在API>19和API<19的机型上都兼容状态栏着色效果。
| API>19 | API <=19 |
|
|
在values、values-v19、values-v21目录下分别创建相应的主题，然后在AndroidManifest.xml中给Application设置该主题。
android:fitsSystemWindows="true"属性 我们使用android:fitsSystemWindows="true"属性，不让布局延伸到状态栏，这时状态栏就是透明的，然后添加一个和状态栏高、宽相同的指定颜色View来覆盖被透明化的状态栏。
