Question

I need help… I got errors with my android xml… Here’s the code:

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

<CheckBoxPreference 
    android:key="music"
    android:title="Music"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:summary="Play Music for each screen"
    android:defaultValue="true" />

<CheckBoxPreference
    android:key="hints"
    android:title="Hints" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:summary="Enable hints during gameplay"
    android:defaultValue="true" />

</PreferenceScreen>

Here is the error messages:

com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
You must supply a layout_width attribute.
You must supply a layout_height attribute.

Thanks in advance..

    <PreferenceCategory android:title="CheckBoxPreference">

             android:title="Music"

        <CheckBoxPreference
