Hi @corwin42
How can I change the ACSearchView btn's gravity?

What do you want to do exactly? Make ACSearchView compatible with RTL languages?

Hi Corwin,

Any chance you could take a look at a forum post of mine (link below) relating to the AppCompat lib? I think that there is an issue with the latest Support Lib from google but at teh moment can't verify. I've cut my app down to the barest minimum and the issue still appears.

Regards

Jon

Sorry my bad, although it had worked I forgot that I needed to update the libs in the custom libs folder with the newer SDK files. I'm a dumbass

3. Copy v4 and v7 support libraries from <...>\android-sdk\extras\android\support\v7\appcompat\libs to your CustomLibs folder

Hey @corwin42, with support library 23.1 setelevation method seem to not work.
This is my code: AppCompat1.SetElevation(actionbar, 4dip) where actionbar is an ACToolbarDark
if i Log appcompat1.getelevation(actionbar) i get 0
is this something you could look at?

Hi All,

I am using Theme.AppCompat.Light.NoActionBar as my parent theme. When the search view is activated, the back arrow is coming in black. I need to change the color to white. Any suggestions how to do that?

Edit : I got it

B4X:

<style name="MyAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="homeAsUpIndicator">@drawable/name  of the icon in resouce folder (the arrow image)</item>
</style>

Best,
SK

I got error this while running the sample, no error while compiling, I've read every page on this thread, follow the instruction
> update the latest sdk & android extra
> makesure the latest b4a_appcompat file by deleting old file
> copy android-support-v4.jar & android-support-v7-appcompat.jar to library folder
> use android-sdk\platforms\android-23\android.jar while compiling
but error still there, I don't know what I'm missing at

Yes, see attached project.

androh · Jan 12, 2016

I want to ripple effect on switch view. But including text, whole row.
How can I do that?

Edit: That's ok. I did that very easy with your example

Example attached.

I recently wrote that setelevation is not working with support lib 23.1 installed.
And this doesn't work either:

B4X:

actionbar.PopupTheme = actionbar.THEME_LIGHT

Does anyone have knowledge regarding this issue?

Be aware that SetElevation() does not work with every View. If it does not work with the View you want then you can put the view on a Panel and set the elevation for the Panel.

PopupTheme should work. Please provide an example project to show that it does not work. I don't have time to create a testcase myself for all bug reports.

Solved the popup theme just by changing the theme from .noactionbar to theme.appcompat.light, but about the setelevation, it doesnt even work with the toolbar, i remeber it did before.

corwin42 · Jan 14, 2016

It should work with the ToolBar. Be aware that it only works on Android 5.0 and above.

Hi All,

I want to use a drawable for the thumb of the seekbar, how should one write the xml attributes to change it? I was referring to the google doc in the below link but I am getting an xml error.

https://chromium.googlesource.com/a...pport/v7/appcompat/res/values/styles_base.xml

I am using the sample theme given in the example.

corwin42 said:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#FF9800</item>
<item name="colorPrimaryDark">#F57C00</item>
<item name="colorAccent">#FFA726</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
</resources>

Any suggestions appreciated. Need to change the seekbar thumb drawable using xml attribute

B4X:

android:thumb

Best,
SK

A workaround would be to place the Toolbar on a panel and elevate the panel.

Alisson said:

No. Everything I can say is that there is an error in your setup. Please check that really everything is up to date and that you use v23 android.jar. See the troubleshooting guide in the first post of the Appcompat library thread.

Corwin42, thanks very much!!
