How to create a suggestion list for custom searches in Android

I have implemented custom content provider suggestions based on this guide ; it works, however i have a problem with making a list of suggestions. The suggestion list I have has a black background and white text. I want to change it to white background and black text. I did a web search and tried something like this in the styles.xml file:

<style name="MySearchViewStyle" parent="Widget.AppCompat.SearchView">
    <item name="suggestionRowLayout">@layout/list_item_search_suggestion</item>
</style>
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="searchViewStyle">@style/MySearchViewStyle</item>
</style>

      

        
        
        
      

    

My list_item_search_suggestion looks like this:

    <?xml version="1.0" encoding="utf-8"?>
<TextView
    android:id="@android:id/text1"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/white"
    android:gravity="center_vertical"
    android:minHeight="56dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:textColor="@android:color/black"
    tools:text="Blah blah blah"/>

      

        
        
        
      

    

However, when I launch the application and search for something, it crashes until the suggestion list appears. I am getting NullPointerException from newView method in SuggestionsAdapter. This adapter offers from the SDK, I am not implementing my own adapter. I just embed the content provider and set it in the searchable.xml file. Also the stack track looks like this:
