B4A Library Preferences - Material Design Preferences

corwin42 · Jan 22, 2017

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.

But if you use this library in your projects and you think it is useful to you please consider to make a donation:

Thanks very much for your support.

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)

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.

Hi,

I have the same problem after upgrade to B4A 9.80.

Erel · Feb 24, 2020

Note that it is not related to B4A version. It is related to the SDK change from Android Support to AndroidX.

Are you using the latest version (v3.00) ?

woniol · Feb 24, 2020

I know it is directly related to AndroidX rather then B4A version.
I get the error message using version 3 of PreferencesLib.

It is also with the example from first post.

woniol said:

You are wrong. It has nothing to do with B4A version. You can use the old Android Support SDK and it will work.

BTW, you can use B4XPreferencesDialog instead.

woniol · Feb 24, 2020

Thats what I meant. It is AndroidX problem not B4A.

Think, I'll have to switch to B4XPreferencesDialog but this will require some additional work.

I have no idea what you are doing wrong. I can't reproduce the problem.

Which android.jar are you using? Are you sure you have the 3.0 library version installed? Have you jetified everything? Have you tried to clean the project?

woniol · Feb 25, 2020

Hi,

I managed to solve it with the following steps:
1. Fresh install of B4A (9.80)
2. New Additional Libraries folder creation (out of Program Files for permissions)
3. Fresh download of the additional libraries (latest versions) needed for my project.
4. Jetified (Tools - Jetifier)
5. Clean project (Tools - Clean project)
and it works......

So it was definitely related to my installation, which was not refreshed for a long time.
I think it is a good idea to have fresh install after switching to AndroidX.

Thanks for your help

Hello
How can I add a profile item to the top of the page?
Please provide a source and an example.

Toky Olivier · May 14, 2023

Hello all and @corwin42,
I'm having the same issue but cleaning all and restart from new installation hasn't solved my case.
The main issue is likely "Didn't find class "androidx.preference.XpPreferenceManager""
Switch to B4XPreference dialog may be a solution even if I have to modify many thing but what will replace PreferenceManager class from @corwin42 Preferences library?

Thank you
