需要修改关机弹窗界面，当前界面我已经按照客户需求去掉emergency

但是客户需要按其他区域可以实现返回，也就是点击黑色背景取消dialog

嗑代码发现黑色布局为：

<node index="0" text="" resource-id="com.android.systemui:id/global_actions_grid_root" class="android.widget.LinearLayout" package="com.android.systemui" content-desc="" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[0,200][1536,1964]"/>
</node>

监听它并取消弹窗：
