Thanks Erel

it works.



But, is there a way to customize this action view, i need to change some properties like font color, background color, top, fixed width and left position.

I need something like this:



This second was created with another tool, and is not a native action bar, its something like a panel with views in b4a.

Have you tried to change the view properties?
Yes

I set up the properties :

B4X:
dim edtTeste as EditText
edtTeste.Initialize("")
edtTeste.Width = 100dip
edtTeste.Hint = "Search !"
edtTeste.TextColor = Colors.White
Dim jo As JavaObject = actionBar
jo = jo.GetField("bar")
jo.RunMethod("setDisplayShowCustomEnabled", ArrayAsObject(true))
jo.RunMethod("setCustomView", ArrayAsObject(edtTeste))
But when i try setup the width or left position i get a java.lang.NullPointerException

As pointed out, it's only supported by Android 4+.

Can't you (possibly through 'support' library) make it available down to 3+ ?

I'we seen 'StdActionBarHelper' by corwin42, but using that is one more brick on top of another, and usually i'm avoiding that if possible.

I managed to use ActionBarCompat from the support library with B4A. It works with some tricks (like modifying the generated Java code in #CustomBuildActions etc.) but it is quite complicated to use and it's a really dirty hack.

I can understand Erel that he (currently) don't want to add support for it because it would make the ActionBar feature quite complicated to use (like adding resource files etc.) and it will need differently generated java code depending on weather ActionBarCompat is used or not. And with a dropping userbase of less than 20% it may be not worth the effort.

Before you ask. Sorry, I won't make my solution public because every new version of B4A may break it totally and I can't do the support for such a dangerous hack.
