B4A Library [Class] ActionBar

Informatix · Aug 23, 2012

Hi,

This class allows to create Action Bars.

There was already a good library to do that (AHActionBar) but I needed more features and more flexibility. So here is my version.

Tutorials: How they do #2, How they do #3

v1.1:
Fixed a bug in RemoveButton
Added ReplacePressedDrawable
Fixed a bug in the demo

v1.2:
New functions:
- ReplaceDividerDrawable(Drawable As Object)
- SetIconAsWideAsText(Enabled As Boolean)
Updated the demos

v1.3:
Fixed a bug in ResizeButton (the text height was not correctly computed)
New function: FillParent
Removed the limitation of SetFixedWidth (there's no longer minimum width)

v1.4:
Optimized the loading of drawables
Added the Drag&Drop feature
New functions:
- getLeftPosition(Btn As View) As Int
- getRightPosition(Btn As View) As Int
- StartDragAndDrop(Btn As View, ViewToBlock As Object, OnAfterDropSub As String)
- AbortDragAndDrop
- MoveButtonTo(Btn As View, NewPosition As Int)
Renamed ID to Btn in function parameters

v1.41:
Fixed an issue with JellyBean.
Fixed a visual bug with successive Drag&Drops.

v1.42:
Fixed the computation of the text size of buttons;
No more warnings with B4A v2.7.

v1.43:
Fixed a bug (division by zero).

Enjoy,
Fred

Has anyone got an error when using action bar class under Lollipop 5.0.0?

I got an error :
java.lang.IllegalArgumentException: unknown bitmap configuration

The error raised when call to functions

B4X:

AB.SameWidthForAll(True)
AB.AddButton(Null, "System", 5, 1, "SysClick", "")

But change the codes to this

B4X:

AB.SameWidthForAll(False)
AB.AddButton(Null, "System", 5, 1, "SysClick", "")

No error raised. Tested it under an Genymotion Emulator. Don't have a change to test it on real device cause don't have device with Lollipop.

Tested with 5.1 on a Nexus 7: no error.
Do you use the latest version?

hi, if i set the height panel at 50 the icon dimension is 50 , how to reduce only dimension icon? Thanks

It is a class so you can modify it on ur own...

Hi,

Great work.

Just one question: is there a way to change the tab color? I've tryed:

B4X:

pnlAB.Color = Colors.ARGB(255,204,204,204)

but it didn't work...

Kind regards,

Kepler

Do you mean, the "line", orange or gray, at the base of the tab? If it is what you mean then the class uses png files to set them.

I misread your question. You can change the panel color this way:

B4X:

  pnlAB.AsPanel.Color = Colors.ARGB(255,204,204,204)

Hi Informatix

I've got a question. The Action Bar doesn't work if we compile the B4A app in the obfuscated mode code release.

Any ideas how to handle this problem?

Kind regards,

Kepler

I use only the obfuscated mode when I develop with B4A, so I'm sure that the class works fine in this mode.

kepler · May 7, 2015

Hi,

Not quite... I've remembered the rules for obfuscating. I was calling one of the menus like this:

B4X:

AB.AddButton(LoadBitmap(File.DirAssets, "home.png"), "", 4, 1, "Home", "")

The action parameter "Home" is turned into a string - so it's not assumed as the defined action. If we, however, put "Home_m" (notice the "_", no blank spaces) as the action, the string is not modified, and everything goes right

Kind regards,

Kepler

??? I don't understand what you mean.
This parameter is the event name (the complete name of the sub handling the event) so you have to name it like an event name, e.g. Home_Click. Look at the demo. If you name it only "Home", it is not properly named and it won't work with obfuscation.

kepler · May 7, 2015

Hi,

Yes, I've realized that. But it's not necessary to put, for instance, the "_Click" text.
I was using it - wrongly - calling a routine like this:

B4X:

Sub Home (ActionBar As ClsActionBar, Btn As View)

And it worked with no obfuscation.

Now, I'm calling:

B4X:

Sub Home_m (ActionBar As ClsActionBar, Btn As View)

And it works aswell - obfuscated or not.

Either way, the action must not have any white spaces, otherwise it won't work if the code is obfuscated - that's my assumption.

Kind regards,

Kepler

I've come across underscore (_) issues previously too, but with WebViewExtra. I was going to mention adding an underscore as explained by @wonder in another post, I also believe that @Erel has explained about this too. I was not 100% sure if adding an underscore would work for you though, so I never posted a response @kepler.

kepler said:

Absolutely. You can name it like you wish, but as it is an event name, the underscore is mandatory for obfuscation and recommended for clarity of code (it's a good habit to have so any other B4A developer recognizes that's an event handler sub).

kepler · May 7, 2015

Yep.

Well...problem solved

Kind regards,

Kepler

How do I change the color text of the other buttons when not active?
I know AB.SetText(Btn, "Q-List", Colors.Yellow, -1 ) will set the color for that button but what about make the others white?

Thanks

Memorize each button reference returned by AddButton in a global variable so you can access any button anywhere.

Hi @Informatix can you give me an example code please?
