Use two themes and set each theme to one activity:

B4X:

'For all other activities
SetApplicationAttribute(android:theme, "@style/Theme.AppCompat")

'Different themes for special activities
SetActivityAttribute(Main, android:theme, "@style/MyAppTheme1")
SetActivityAttribute(Second, android:theme, "@style/MyAppTheme2")

CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme1" parent="@style/Theme.AppCompat">
        <item name="colorPrimary">#FF9800</item>
        <item name="colorPrimaryDark">#F57C00</item>
        <item name="colorAccent">#FFA726</item>
    </style>
    <style name="MyAppTheme2" parent="@style/Theme.AppCompat">
        <item name="colorPrimary">#009800</item>
        <item name="colorPrimaryDark">#007C00</item>
        <item name="colorAccent">#00A726</item>
    </style>
</resources>

Hi @corwin42 .
Great library and thank you very much for this.
Anyway i see that using version 3.20 works without any problem on Android 5 or >. But crashes if you use Android 4 (which does not happen on the version 2 library that works on both Android version 4/5/6).
Any suggestion ?

I had this problem before and solved it with @corwin42's help on post #199
Follow the steps and it should be resolved.
particular this step

Check if the only existing folder in <SDK>\build-tools is the 23.0.3 folder.

You are right.

\build-tools is the 23.0.3 folder

This is the key.
Now work without problem Android 4 or >.
Thank you for your help

V3.30

New: Support for ActionViews in MenuItems (Needed for CustomViews in NavigationView of DesignSupport library)

With the new version of AppCompat V3.30, will it be possible to show a badge on the ACMenuItem displayed on the ToolBar as shown on the below given post ?

https://www.b4x.com/android/forum/t...cmenuitem-shown-on-toolbar.68900/#post-446042

I have seen many apps with this feature, unfortunately, till now, I could not find any other way to get this done on my app. Or am I in the wrong track to get this done ?

Regards

Hello! Is there a way to change the corner radius and elevation for ACButton?

Yes. It should be possible to put nearly every View as an ActionView to the ActionBar/ToolBar now.

You can't change the corner radius because it is in the default background drawable of the button.
You can change the Elevation of every view with the AppCompat.SetElevation() method (on some view types this won't have an effect but ACButton should work).

Any sample available demonstrating the usage of the above said.

Currently I have none. I needed the feature for the upcoming version of DesignSupport library. But because it works there it should work in the Toolbar, too.
I will create an example in near future. Maybe I will write some small tutorials for this and other new features.

Hi All,

I am using ACCheckbox and I want it to be in a custom white color. I am using the below method to set the checked color given in the link https://www.b4x.com/android/forum/threads/checkbox-checked-color.61779/#content

B4X:

'Pass the Checkbox object and Colors int values to set for each state.
Sub SetColorTintList(CB As CheckBox,Checked As Int,Enabled As Int,Disabled As Int)

    Dim States(3,1) As Int

    States(0,0) = 16842912   'Checked
    States(1,0) = 16842910    'Enabled
    States(2,0) = -16842910 'Disabled


    Dim Color(3) As Int = Array As Int(Checked,Enabled,Disabled)

    Dim CSL As JavaObject
    CSL.InitializeNewInstance("android.content.res.ColorStateList",Array As Object(States,Color))
    Dim CB1 As JavaObject = CB
    CB1.RunMethod("setButtonTintList",Array As Object(CSL))

End Sub

It works great on Android 5 and 6 but I am getting the below error in honor4x Android 4.4.4

B4X:

Exception java.lang.RuntimeException: Method: setButtonTintList not found in: android.support.v7.widget.AppCompatCheckBox

I checked the google devloper website and the method does not exists but an inherited xml from compactbutton class is present. Any idea what can be done.

Best,
SK

Instead of

B4X:

CB1.RunMethod("setButtonTintList",Array As Object(CSL))

use

B4X:

CB1.RunMethod("setSupportButtonTintList",Array As Object(CSL))

Hi corwin,
Is there a way to make material dialogs work on Android 4.x ?

PABLO2013 · Sep 10, 2016

many tks

Reids · Sep 11, 2016

Hi corwin, it seem the appacompat lib has a bug in .ButtonColor properties on version 36 google support library, which button displayed as gray button but
on previous version of 23 google support library button working nicely *this problem occured in android version 4, which not occured on version 6.
Oh if you suggest me to use .color properties the button will have bigger padding which is not elegant
your appcompat library ACbutton has .ButtonColor properties which is very cool!
I forced to use version 36 because design support require support lib of version 36

Thanks

Remove the #AdditionalRes lines except the ..\resource one.
As DonManfred said, read the first post for detailed project setup instructions.

Hi Corwin,
Love the library but have a question: How do you define other items in the theme? For example primary text color, divider color, etc?
If I add them to the manifest, compilation gives error:

Generating R file. Error
res\values\theme.xml:7: error: Error: No resource found that matches the given name: attr 'colorTextPrimary'.

Any thoughts?
Thanks heaps
