Fixing and Extending the Library

Some days ago, I started building a Setting Screen for my Android app. Everything was fine, until I opened it on an older Android version. The overview screen had no material design, a thing I would have accepted, if there weren’t those completely destroyed dialogs: Android’s internal preferences are using Android’s internal app.AlertDialogs. Those dialogs in combination with the AppCompat Dialog Theme, which I had applied to them, resulted in a dialog with two frames on older devices (One system default dialog and a material frame around it).
So I decided to switch to the library, only to face a lot more issues.

This tutorial series should help you, to fix the numerous design issues in the v7.preference library and to build custom preferences.

This part of the tutorial was updated to use the latest version (v28.0.0) of the support library. It still contains the information on how to fix issues with some older versions.

Building The Preference Screen

Creating the Preferences


android:title="Category 1">

android:title="Switch Preference"
android:summary="Switch Summary"
android:defaultValue="true" />

android:title="EditText Preference"
android:summary="EditText Summary"
android:dialogMessage="Dialog Message"
android:defaultValue="Default value" />
android:title="CheckBox Preference"
android:summary="CheckBox Summary"


The v7.preference library provides some preferences we can use: CheckBoxPreference, SwitchPreferenceCompat, EditTextPreference and a ListPreference (and a basic Preference). If we need more than these predefined preferences, we have to build them on our own.

Creating the Preference Fragment

import;class SettingsFragment: PreferenceFragmentCompat() {    override fun onCreatePreferences(bundle: Bundle?, s: String?) {
// Load the Preferences from the XML file

We can add this SettingsFragment (, like any other Fragment (e.g. with a FragmentTransaction) to an Activity.

Applying the Preference Theme

The result should look like this. In this example the Activity’s parent theme is Theme.AppCompat and the background is set with android:windowBackground. We can change the color of the CheckBox, the Switch and the PreferenceCategory title by changing the colorAccent in our Activity’s theme. If you specifically want to customize the theme of the preferences, you can do so by overriding the following attribute in your Activity’s theme and extending the predefined ThemeOverlay:

<style name="Theme.App" parent="Theme.AppCompat">
<item name="preferenceTheme">@style/Theme.App.Preferences</item>
<style name="Theme.App.Preferences" parent="PreferenceThemeOverlay">

Using Older Versions of the Support Library

The App might crash with an IllegalStateException if you do not specify the preferenceTheme attribute in you Activity’s theme. To resolve this issue, just add it as mentioned above.

You might also experience some design issues similar to the following. As you can see, it has an oversized font and a horizontal line below the category title. This is definitely not following the material design guidelines. It more looks like a mixture of material design for the CheckBox and Switch widgets on the right and an old design for everything else.

This happens because older versions of the support library do not directly include the necessary material themes. They are included in the v14.preference library. It is an addition to the v7.preference library that requires a higher minimum SDK version. This means for us, that we have to add one more line to our dependencies.

Now we have access to two more themes: PreferenceThemeOverlay.v14 and PreferenceThemeOverlay.v14.Material. To use the material theme, we simply change the preferenceTheme in our Activity’s theme.

<item name="preferenceTheme">

After applying this, the font should not be oversized anymore and also the horizontal line below the category title should have disappeared.

A side effect of including the v14.preference library is that we can use a new preference called MultiSelectListPreference (it requires the v7.preference library to work).

This was only the first step to create a material design Settings Screen. As soon as you open the Alert Dialog of the EditText preference, you will find more design issues. The next parts of this tutorial will include how to solve the design issues and how to build custom preferences.

The second Part of this tutorial series is available below.

You can have a look at the project files on GitHub.

Thanks for reading and happy coding 💻.
