*注意点：

---

• NavigationView不设置android:fitsSystemWindows=”true”
• CoordinatorLayout设置android:fitsSystemWindows=”true”
• values-v21下设置Theme属性android:statusBarColor为透明

Activity代码

使用SystemBarTintManager（https://github.com/jgilfelt/SystemBarTint），设置状态栏颜色

注：
5.0以上Android版本会自动适配，theme主题中的属性，不需要额外适配。

if(Build.VERSION.SDK_INT==Build.VERSION_CODES.KITKAT){            SystemBarTintManager systemBarTintManager=new SystemBarTintManager(this);            systemBarTintManager.setStatusBarTintEnabled(true);         systemBarTintManager.setStatusBarTintResource(statusBarColor);            systemBarTintManager.setNavigationBarAlpha(0.2f);        }

如果当前Android版本等于4.4，使用SystemBarTintManager适配。
