Android 沉浸式改变小米魅族状态栏颜色的实例代码

这个是基于SystemBarTintManager更改的

增加一个方法:用于更改MIUIV6系统上的状态栏字体颜色 ,目前我仅仅只发现MIUIV6上可以更改,在android5.0上以及其它4.4以上系统没有发现可以更改字体颜色的代码

核心代码:   

 public void setStatusBarDarkMode(boolean darkmode, Activity activity) { 
  if (sIsMiuiV6) { 
   Class<? extends Window> clazz = activity.getWindow().getClass(); 
   try { 
   int darkModeFlag = 0; 
   Class<?> layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams"); 
   Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE"); 
   darkModeFlag = field.getInt(layoutParams); 
   Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class); 
   extraFlagField.invoke(activity.getWindow(), darkmode ? darkModeFlag : 0, darkModeFlag); 
   } catch (Exception e) { 
   e.printStackTrace(); 
   } 
  } 
 }
