Custom ListVIew is not showing up

I'm trying to create a custom ListView. In another project I created an xml row_client and in the ListView I put tools:listitem="@layout/row_cliente" , however it does not appear in my custom list, but the default list. Does anyone know why?

Custom ListView:

ListViewCode:

<ListViewandroid:id="@+id/listViewCliente"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:listitem="@layout/row_cliente">

Customer row code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:orientation="horizontal" >

    <TextView
        android:text="TextView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:id="@+id/textView3"
        android:paddingLeft="100dp"
        android:layout_weight="1"
        android:textAppearance="@style/TextAppearance.AppCompat.Large" />

    <ImageView
