Android EditTextPreference style

Question

In my app in setings I use EditTextPreference , and on android API uder 11 edittext field has black background and black text color. How can I chenge EditTextPreferences background color ?

I tried: in theme :

<item name="android:editTextPreferenceStyle">@style/EditTextAppTheme</item>

in style:

<style name="EditTextAppTheme" parent="android:Widget.EditText">
      <item name="android:background">@drawable/edit_text_holo_light</item>
      <item name="android:textColor">#000000</item>
  </style>

If I set style to :

<style name="EditTextPreferences" parent="android:Preference.DeviceDefault.DialogPreference.EditTextPreference">
      <item name="android:background">@drawable/edit_text_holo_light</item>
      <item name="android:textColor">#FF0000</item>
  </style>

And theme to :

<item name="android:editTextPreferenceStyle">@style/EditTextPreferences</item>

I got error:

error: Error retrieving parent for item: No resource found that matches the given name 'android:Preference.DeviceDefault.DialogPreference.EditTextPreference'.

I have been trying to figure this out as well for the past couple of days. I've found that all the EditTextPrefence extends is AlertDialog and EditText. So if you can style both of those in your theme, you will find the result you are looking for in a EditTextPreference. Here's what I'm working with:

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

<style name="LightTheme" parent="android:Theme.Light">
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@color/greyscale2</item>
    <item name="android:textColor">@color/greyscale16</item>
    <item name="android:textViewStyle">@style/LightTextView</item>
    <item name="android:buttonStyle">@style/LightButton</item>
    <item name="android:editTextStyle">@style/LightEditText</item>
    <item name="android:alertDialogTheme">@style/LightDialog</item>
    <item name="android:dialogPreferenceStyle">@style/LightDialog</item>
    <item name="android:colorBackground">@color/greyscale2</item>
    <item name="android:colorBackgroundCacheHint">@color/greyscale1</item>
</style>

<!-- TextView -->
<style name="LightTextView" parent="android:Widget.TextView">
    <item name="android:textColor">@color/greyscale16</item>
    <item name="android:background">@android:color/transparent</item>
</style>

<!-- Button -->
<style name="LightButton" parent="android:Widget.Button">
    <item name="android:textColor">@color/greyscale16</item>
    <item name="android:background">@drawable/light_button_background</item>
    <item name="android:gravity">center_vertical|center_horizontal</item>
</style>

<style name="LightCheckBox" parent="android:Widget.CompoundButton.CheckBox">
    <item name="android:background">@color/greyscale2</item>
</style>

<style name="LightEditText" parent="android:style/Widget.EditText">
    <item name="android:background">@color/greyscale1</item>
    <item name="android:editTextBackground">@color/greyscale2</item>
    <item name="android:textColor">@color/greyscale16</item>
    <item name="android:button">@style/DarkButton</item>
    <item name="android:inputType">number</item>
</style>

<style name="LightDialog" parent="@android:style/Theme.Dialog">
    <item name="android:background">@color/greyscale2</item>
    <item name="android:textColor">@color/greyscale16</item>
    <item name="android:textViewStyle">@style/LightTextView</item>
    <item name="android:buttonStyle">@style/LightButton</item>
    <item name="android:divider">@color/greyscale14</item>
</style>

Notice the <item name="android:dialogPreferenceStyle">@style/LightDialog</item> attribute in my base theme. I found the styleable resource here, more specifically alertDiaolg here (Note: These can also be found in your SDK directory on your computer)

I hope this at least heads you in the right direction, I have been struggling to figure this out (my first theme in my apps). Happy Coding!
