整理代码如下:

小米:

public void setStatusBarDarkMode(boolean darkmode, Activity activity) {
    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();
    }
}

魅族:

public static boolean setStatusBarDarkIcon(Window window, boolean dark) {
    boolean result = false;
    if (window != null) {
        try {
            WindowManager.LayoutParams lp = window.getAttributes();
            Field darkFlag = WindowManager.LayoutParams.class.getDeclaredField("MEIZU_FLAG_DARK_STATUS_BAR_ICON");
            Field meizuFlags = WindowManager.LayoutParams.class.getDeclaredField("meizuFlags");
            darkFlag.setAccessible(true);
            meizuFlags.setAccessible(true);
            int bit = darkFlag.getInt(null);
            int value = meizuFlags.getInt(lp);
            if (dark) {
                value |= bit;
            } else {
                value &= ~bit;
            }
            meizuFlags.setInt(lp, value);
            window.setAttributes(lp);
            result = true;
        } catch (Exception e) {
            Log.e("MeiZu", "setStatusBarDarkIcon: failed");
        }
    }
    return result;
