Bal2Bjl - Deprecated - see post #1

[stevel05]

Following on from Erel and @Filippo 's work, I have spent a little time and added some functionality to the code. I have tried it with some very old and complex B4a layouts and it seems to work, but I'm sure there will be some issues along the way.

If it doesn't work first time, try saving the B4a layout with a newer version.

If the layout contains custom views, don't forget to create the custom view class module. It can be empty until you are ready to rewrite it, but it needs to be there for the layout to display.

There is still some logging in the code, which I will leave for now.

Let me know if it works for you.

Hope it helps.

Update 0.2 added a missing Drawable variant.

Note: this utility is now redundant as you can copy and paste layouts between IDE's on different platforms which is much easier.


0.2 : 54

Fixed Scrollview Implementation and added default entries for MaterialIcons and FontAwesome

Hi Steve. Following on from our conversation on this thread https://www.b4x.com/android/forum/threads/bal2bjl-with-source.68428/#post-544397, I can confirm that the latest version has corrected the issue. Thanks again for making this available!

Is it a new layout or from an old project?

 

[Robert Valentino]

I am using 7.01 of B4A and just verified that I edited the screen and saved it to make sure it was updated.

Still same crash

 

[stevel05]

This may take some time, there is something on the layout that is not being parsed correctly. The easiest way to find it will be to remove the views one at a time until it starts to work. I am not going to have much time for programming this weekend, if you would like to try it then feel free. If not, I will have a go probably on Tuesday.

 

[Robert Valentino]

Will see what I can do.

 

[Robert Valentino]

Well, turns out I had Padding checked on 2 label fields and set to 5, 0, 0, 0

Padding doesn't exist - NOT sure how to modify the program to handle padding.

 

[stevel05]

Easiest thing would be to remove the padding, it would be ignored on the import anyway. You'll probably have to set it using cssutils.

 

[Robert Valentino]

Exactly what I did. But for the future it would be nice if the program did that.

But works GR8

Thanks

 

[stevel05]

I'll take a look, but I'm not sure how to do that. It's Erel's code that parses the layout.

nice work @stevel05. can it also do bjl2bal ? just finished a b4j project and would like to convert the layouts to bal files.
thanx

 

[stevel05]

No I'm afraid not.

 

[stevel05]

@Erel Please add this to your list of posts to archive it may help to avoid confusion.

Thanks

 

[Erel]

Done. Thank you.
