搜索栏搜索listView

Question

我制作了一个应用程序，其中包含使用listView的保险公司列表。使用数组适配器填充listView。我希望能够使用搜索栏搜索此列表，并且只返回搜索到的保险公司。我已经完成了一个教程，但它没有过滤保险公司。有人能告诉我哪里出错了吗

到目前为止，这是我的代码

insurance.xml

    <EditText
        android:layout_width="400dp"
        android:layout_height="60dp"
        android:id="@+id/editText"
        android:layout_marginBottom="50dp"

/>
    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginTop="107dp">
    </ListView>
