Hello I have a layout for my ListView and it overlaps with my toolbar when I run the program. Please find below my codes.
XML for my LIstView.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    tools:context=".CarSublist">

    <!-- TODO: Update blank fragment layout -->
     <ListView
        android:id="@+id/android:list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_gravity="start" />
    <TextView
        android:layout_width="wrap_removed"
        android:layout_height="wrap_removed"
        android:id="@+id/topText"
        android:singleLine="true"
