I also encountered this problem with a spinner I solved it like this

child xml.

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#839096"
android:orientation="vertical" >

<TextView
    android:id="@+id/itemChildTitle"
    android:layout_width="match_parent" <== and this
    android:minWidth="500dp"  <=== add this
    android:layout_height="wrap_content"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge"
    tools:ignore="HardcodedText" />

 </LinearLayout>
