[Gianni Sassanelli]

Hi
i want to add a user theme selector in my app, for example i need Blue, Green, Red, Purple...
For this i need to change in B4A code some attributes of action bar and it's elements, but i don't know how to

Now i do the following code in B4XPage_Appear

    ' Set Title of page
    ' with a specific Textcolor  -- don't require manifest and it's fine form me
    Dim cs                         As CSBuilder
    Dim ThemeTextColor         As Int 
    Dim ActionBarCaption     As String 
    ThemeTextColor             = xui.Color_White
    ActionBarCaption            = "Home"
    cs.Initialize.Size(22).Color(ThemeTextColor).Append(ActionBarCaption).PopAll

    B4XPages.SetTitle(Me,cs)    
     
     ' Set BackGround of ActionBar  -- without manifest... 
     'Work fine in B4a  but Don't know if is right on B4I
    Dim cd As ColorDrawable 
    cd.Initialize(xui.Color_RGB(0,93,192),0)
    B4XPages.GetManager.ActionBar.RunMethod("setStackedBackgroundDrawable", Array(cd))
    

     'Set HomeIcon of ActionBar  -- without manifest... 
    'Work fine in B4a  but Don't know if is right on B4I

    Dim bd As BitmapDrawable
    bd.Initialize(LoadBitmap(File.DirAssets,"myGoHomeIcon.png"))
    B4XPages.GetManager.ActionBar.RunMethod("setDisplayHomeAsUpEnabled", Array(True))
    B4XPages.GetManager.ActionBar.RunMethod("setHomeAsUpIndicator", Array(bd))
    
    
     'Set HomeIcon of ActionBar  -- without manifest... 
    'Work fine in B4a  but Don't know if is right on B4
    'Force visibility of goHome Icon
    B4XPages.GetManager.ActionBar.RunMethod("setDisplayShowHomeEnabled", Array(True))

to complete my request i have 2 question :
1) how to change the menuIcon Bitmap or MenuIcon color by code
2) if the code that i have posted working in b4I also

2) Any code that accesses ActionBar will not work in B4J or B4i.
Your code will also break the built-in up icon handling.

1) Try this:

B4XPages.GetManager.ActionBar.RunMethod("setColorFilter", Array(XUI.Colors_Red, "SRC_ATOP"))

 

[Gianni Sassanelli]

setColorFilter return error

java.lang.RuntimeException: Method: setColorFilter not found in: com.android.internal.app.WindowDecorActionBar

Seems like it is not possible to change the menu color at runtime. If you find Java code that does it, I can help you port it.

Hi Erel, first of all thank you for your precious help.
I am trying to use the B4XPage mode for development of my app but I am finding different difficulties compared to the old mode
Certainly due to my gaps in knowledgebase.
For ActionBar, to overcome some Android limits I used in past Fullscreen with noTitle mode in my activities.
Each one of it contain on the top a panel in witch I put all i need and drive as I like best.
With the pages I seem to have understood that the use in fullscreen is not recommended and therefore I am trying to manage the action bar with all the problems encountered.
Today i found another that concerns the textColorPrimary attribute inserted in the Manifest to change the colors of the objects in the ActionBar.
This work fine for ActionBar but changes the foreground color for many views of the whole app.
For example the text of the msgbox also turns white, but for this I am opening a new Thread

With the pages I seem to have understood that the use in fullscreen is not recommended

???
Why isn't it recommended?

???
Why isn't it recommended?

I seem to have read this in one of the many posts that I have readed
and some problems with IME when Hide and Show keyboard for example

This is a known issue. IME will not work properly when the activity is a full screen activity: https://www.b4x.com/android/forum/t...-keyboard-with-the-ime-library.14832/#content

Everything in this thread is wrong.
The IME + full screen issue has nothing to do with B4XPages.
