Android 如何在同一屏幕中添加两个SimpleCorsorAdapter？

我正在创建一个使用两个SearchView组件的屏幕，对于每个组件，我都需要添加建议框（SimpleCursorAdapters）。但是我的建议框面临一个问题，因为它们都连接到在我的XML布局中创建的第一个SearchView

这是我的，这是我的

正如您所看到的，正在“我的调查搜索”下创建“我的网站搜索建议”框

有人知道如何处理建议箱的位置吗

这是my 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"

    <SearchView

        android:iconifiedByDefault="false"
        android:layoutDirection="rtl"
        android:queryHint="Search Survey Here"
        app:layout_constraintTop_toTopOf="parent"
        tools:layout_editor_absoluteX="0dp" />

    <SearchView
        android:id="@+id/site_search_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentEnd="true"
        android:layout_marginTop="176dp"
        android:background="@drawable/search_box_border"
        android:clickable="true"
        android:iconifiedByDefault="false"
        android:layoutDirection="rtl"

        app:layout_constraintTop_toTopOf="parent"
        tools:layout_editor_absoluteX="0dp">
    </SearchView>
