StatusBarUtil.setLightMode(this) => Toolbar goes behind statusBar about statusbarutil HOT 1 OPEN

I find this question too. The question is this util change your theme in this two func. You could change this func in util like this.
`
@TargetApi(Build.VERSION_CODES.M)
public static void setLightMode(Activity activity) {
setMIUIStatusBarDarkIcon(activity, true);
setMeizuStatusBarDarkIcon(activity, true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int visibility = activity.getWindow().getDecorView().getSystemUiVisibility();
if (visibility != (visibility | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR)) {
visibility = visibility | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;
}
activity.getWindow().getDecorView().setSystemUiVisibility(visibility);
}
}

@TargetApi(Build.VERSION_CODES.M)
public static void setDarkMode(Activity activity) {
    setMIUIStatusBarDarkIcon(activity, false);
    setMeizuStatusBarDarkIcon(activity, false);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        int visibility = activity.getWindow().getDecorView().getSystemUiVisibility();
        if (visibility == (visibility | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR)) {
            visibility = visibility ^ View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;
        }
        activity.getWindow().getDecorView().setSystemUiVisibility(visibility);
    }
}`
