我对Android完全陌生，我决定创建一个类似Siri外观的应用程序，工作正常，我在询问之前进行了搜索，但我无法让它工作：{{3 }}
所以我想在我的Android应用程序中隐藏弹出窗口，但我现在真的不知道如何正确地做到这一点。如果有人能帮助我这样做，我会很高兴。我已在Android Manifest中添加了正确的权限...

第1步
在Android Manifest.xml中，添加权限。
<uses-permission android:name="android.permission.RECORD_AUDIO" />
第2步 在布局屏幕中，我使用切换按钮来开始/停止语音聆听。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
.......
<ToggleButton
android:id="@+id/toggleButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="26dp"
android:text="ToggleButton" />
......
</RelativeLayout>
第3步 - 活动类
