Android Question change Activity menu icon after added

[John Decowski]

Hi i have created a menu icon using Activity.AddMenuItem3 I would like to know how to modify the icon created from this method.

Activity.AddMenuItem3("Notify", "Notify",LoadBitmap(File.DirAssets, "notify9.png"),True)

Thanks in advance.

I'm not aware of any way to do this in B4A code, but you might be able to do it using Java. Try Googling something like "Android change activity menu item at runtime" & see what you can find.

Use AppCompat.

This is a good example to start with AppCompat.
AppCompat with ToolBar - minimal example

Hello,

When i try to use the example AppCompat with ToolBar - minimal example :
from : https://www.b4x.com/android/forum/attachments/appcompatexample-zip.85601/

with : B4X 3.9 / AppCompat : 3.52 / SlidingMenuWrapper : 1.10 (the Android SDK BuildTools is: 27.0.1)

I get the Error at Activity.LoadLayout("1") :

with : B4X 3.9

Update B4A, use V9.8 - It is free now. I don´t think you´ll successfully get a App working on newer devices with this old B4A Version.

AppCompat : 3.52

Use Appcompat 4.0

 

[ALBRECHT]

sorry, i m wrong with the version of the Core: i m using Version 9.80 (not 3.80)
Great, all is ok with : AppCompat 4.00
Thanks
