适用于沉浸状态栏，该代码需要放置于设置沉浸状态栏后面，代码详见：

如果隐藏状态栏

/**

 *
 * @param context
 */
public static void hideStatusLan(Activity context) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        context.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        context.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        VirtualKeyUtils.getInstance().noBarResizeChildOfContent();
    }

}
