ListView inside QustomDialog cut the bottom

[Shadie6]

I set the ContentView of a QustomDialog with a ListView, but when I scroll down, the last element isn't showing properly.

My layout is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="600dp"
    android:layout_height="400dp"
    android:orientation="vertical">

    <ListView
        android:id="@+id/dialog_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbarStyle="insideOverlay"
        android:dividerHeight="1dp" />

</LinearLayout>

is there something missing?
