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();
   }
  }
 }

  fwRootLayout.setFitsSystemWindows(true);//需要把根布局设置为这个属性 子布局则不会占用状态栏位置
  fwRootLayout.setClipToPadding(true);//需要把根布局设置为这个属性 子布局则不会占用状态栏位置
  }
  tintManager = new SystemBarTintManager(this);// 创建状态栏的管理实例
  tintManager.setStatusBarTintEnabled(true);// 激活状态栏设置
  tintManager.setNavigationBarTintEnabled(true);// 激活导航栏设置
  tintManager.setStatusBarTintColor(getResources().getColor(R.color.blue500));//设置状态栏颜色
  tintManager.setStatusBarDarkMode(false, this);//false 状态栏字体颜色是白色 true 颜色是黑色
