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();
  }
 }
}
