我正在创建一个使用两个SearchView组件的屏幕，我需要为每个组件添加建议框（SimpleCursorAdapters）。但是我的建议框遇到了问题，因为这两个提示框都已附加到在我的XML布局中创建的第一个SearchView中。
这是我的Survey Search，这是我的Site Search。
您会看到我的“问卷调查”下正在创建“网站搜索”建议框。
有人知道如何处理建议框的位置吗？
这是我的layout.xml：
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent">
<SearchView

android:iconifiedByDefault="false"

<SearchView

有人知道我在做什么错或如何处理这种行为吗？
非常感谢！
