B4A Library Preferences - Material Design Preferences

This library provides a framework to create nice looking Material Design Preferences down to API9. It uses this GitHub project to fix some bugs in the android support preferences stuff. It also adds some nice features like simple icon tinting, simple menu list preferences and a color picker.

For a guide on how to implement settings for Material Design read this.

Installation:
  • Extract all of the PreferencesLibX_XX.zip file to your additional libraries folder. These are .xml, .jar, 4 .aar files.
  • Requires AppCompat library.
  • Requires B4A 6.31+
minimum SDK Version: 14
Needs support library 27

If you are updating you can delete the old library aar files.

Your Support:

Creating libraries and wrappers for existing library projects is a lot of work. The use of this library is totally free and you even don't need to mention in your app that you use it.

Usage:

You need to use AppCompat Library together with this library.
Don't forget to add the Preference library to your project.

1. Enhance your theme in manifest editor
Add a preferenceTheme item and the two items for the IconTint:
B4X: 
CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">#0098FF</item>
        <item name="colorPrimaryDark">#007CF5</item>
        <item name="colorAccent">#FF5522</item>
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="preferenceTheme">@style/PreferenceThemeOverlay.Material</item>
        <item name="asp_preferenceIconTint">?colorAccent</item>
        <item name="asp_preferenceDialogIconTint">?asp_preferenceIconTint</item>
        <item name="windowActionModeOverlay">true</item>
    </style>
</resources>
)

2. Extend from AppCompatPreferenceActivity
B4X: 
#Extends: de.amberhome.preferences.AppCompatPreferenceActivity

3. Add PreferenceView to your Layout (with designer or by code)
DesignerPreferenceView.png

4. Load the Layout in Activity_Create() as normal

5. Create your Preference elements in PreferenceView_Ready() event.

See the example for detailed usage.

The example has minSdkVersion set to 14. This is because the MaterialDateTimePicker needs this. The Preference library itself will work with a minimal SDK version of 9.

The example projects additionally needs MaterialDateTimePicker, XMLLayoutBuilder and DateUtils libraries.

Running into something strange. I added a second Edit.InputType, the first being set to INPUT_TYPE_DECIMAL_NUMBERS and the second set to INPUT_TYPE_DECIMAL_Text. The correct keyboard comes up for both. The EditTextPreference set to INPUT_TYPE_DECIMAL_NUMBERS I can see update in the log. The EditTextPreference set to INPUT_TYPE_DECIMAL_Text does not update in the log. Any ideas?

Thanks for this library.

Is it possible to use divider lines to group together related settings?

I can confirm this. I will try to update the original library. Hopefully this will fix the problem. The author says that Version 2.3.2 is compatible with AndroidX. My wrapper still uses 2.2.0.

In "tools..." I don't have a "b4a_local" Folder. This is only available in the root directory "Extras". Even in an older backup.

While we are waiting, if you want to update your SDK and want this library to work, then avoid updating Androidx.Preference.Preference

Thanks for the tip. Now I have updated my SDK again after the backup. Great.

You will find library version 3.0 in the first post which should fix the issue with the latest androidx support library.

I could only fix this issue removing the RingtonePreference. RingtonePreference is not supported anymore in AndroidX libraries. You need to create a custom preference and work with Phone.RingtoneManager to work around this.
