<h3>一、前言：</h3>
<p>如果是<strong>系统级应用</strong>，也就是手机厂家植入的应用，比较简单，修改<code>frameworks</code>里代码， 可以参考：<a href="https://blog.csdn.net/qq_35981307/article/details/73843704" target="_blank" rel="nofollow">基于Android6.0源码修改屏蔽系统下方的虚拟按键以及上方的状态栏</a>。但是如果是在应用层上的，这里使用<code>StatusBarManager</code>实现此功能，<code>StatusBarManager</code>是<code>Android</code>许多隐藏<code>Service</code>中的其中之一，该<code>Service</code>不对外提供，如果我们要使用的话可以通过<strong>反射</strong>来获取其方法。因为权限问题无法使用（如果一定要使用必须具有<strong>系统签名</strong>），只能做在定制机上，如果你想做在第三方应用上发布，其设备是没有办法使用隐藏的方法</p>
<hr>
<h3>二、准备：</h3>
<ul>
<li>签名文件</li>
<li>APP程序</li>
</ul>
<hr>
<h3>三、实现步骤：</h3>
<h5>1.在AndroidManifest.xml中添加权限</h5>

<p><strong>注意：</strong><code>0x00010000</code>和<code>0x00000001</code>是不同版本下禁止下拉的整形标识，如果我们想还原下拉，只需要将整形标识改为<code>0x00000000</code>即可</p>
<h5>3.签名</h5>
<p>需要签名，属于系统操作，特定签名文件如下:</p>
<br>
<div class="image-package">
<div class="image-container" style="max-width: 383px; max-height: 180px; background-color: transparent;">
<div class="image-container-fill" style="padding-bottom: 47.0%;"></div>
