如何在SearchView中将查询提示文本垂直居中

<style name="CustomSearchView" parent="Widget.AppCompat.SearchView">
    <item name="android:searchViewTextAppearance">@style/CustomSearchViewTextAppearance</item>
</style>

<style name="CustomSearchViewTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textSize">16sp</item> <!-- 根据需要设置文本大小 -->
    <item name="android:gravity">center_vertical</item> <!-- 设置文本垂直居中 -->
</style>

<androidx.appcompat.widget.SearchView
    android:id="@+id/searchView"
    style="@style/CustomSearchView"
    ... />

SearchView searchView = findViewById(R.id.searchView);
searchView.setQueryHint("查询提示文本");
