B4A Library [B4X] B4XGifView - Cross platform animated gif view

1591098949811.png


I was missing a cross platform, animated gif view, so created one.

Usage is simple:
Add with the visual designer and call SetGif to set the gif file.


The B4i implementation depends on FLAnimatedImage open source project: https://github.com/Flipboard/FLAnimatedImage
The FLAnimatedImage library was uploaded to the hosted builders. If you are using a local Mac then download FLAnimatedImage-Mac and copy the files to the Libs folder.
The B4A implementation is based on this open source project: https://github.com/koral--/android-gif-drawable
The two dependent aars are attached. Copy them to B4A additional libraries folder.

Updates:

1.12 - SetGif2 - Allows loading an animated gif from an array of bytes.
1.11 - GIF image ratio is preserved.
1.10 - New B4A implementation based on Android GIF Drawable. It provides better performance. Note that the Activity_Resume method has been removed. Don't miss the B4A-Dependencies zip file.

You need to download B4A-dependencies.zip, unzip it and copy the files to the additional libraries folder. It is attached to the first post.

Hi Erel, do you think you can add a click event to this library?
Thank you!

I tried editing the source code and added:

B4X: 
#Event: Click

Private Sub iv_Click
    If xui.SubExists(mCallBack,mEventName&"_Click",0) Then
        CallSub(mCallBack,mEventName&"_Click")
    End If
End Sub

Nothing happens when I click the view. I think I might be doing something wrong?

it could be other languages I am used to but
mEventName&"_Click"
in a continuous line looks odd to me
does
mEventName & "_Click" work?

I tried to format it correctly but nothing happens when I click. Maybe the view that is being returned isn't the one that is actually being clicked on?

Sorry I cant help much I've never dived into the source code of any of the controls before but I think you may be on the right track.
They are usually made up of a few control and IV is like the base for getting at the other controls, so yeah, dig a bit deeper, the click event of some of the other controls may yield a result. Good luck

Also, it's best not to post questions directly at Erel, as we are all here to help if we can.
plus @klaus will tell you off ;)

I know there are many great talented people here, I just assumed since Erel created it, I should direct the attention of the person writing the library.

The wrong thing is that you should also set the event name when the ImageView is initialized, within the DesignerCreateView routine:
B4X: 
Public Sub DesignerCreateView (Base As Object, Lbl As Label, Props As Map)
    mBase = Base
    Tag = mBase.Tag
    mBase.Tag = Me
    #if B4J
    iv.Initialize("iv") '<--------- here
    mBase.AddView(iv, 0, 0, mBase.Width, mBase.Height)
    #Else If B4i
    Dim no As NativeObject
    AnimatedImageView = no.Initialize("FLAnimatedImageView").RunMethod("new", Null)
    mBase.AddView(AnimatedImageView, 0, 0, mBase.Width, mBase.Height)
    Dim iv As ImageView = AnimatedImageView
    iv.ContentMode = iv.MODE_FIT
    #Else If B4A
    iv.Initialize("iv") ' <--------- here
    mBase.AddView(iv, 0, 0, mBase.Width, mBase.Height)
    #End If
End Sub
As you can see I did it and it works but I couldn't do it for B4i.

I'm attaching a version (1.12) that works with B4A and B4J; Erel will probably be able to fix it to work with B4i as well.

Ahh of course, there is no event name so there is no _click event for the iv. ?‍♂️

It works for B4J and B4A.
I tried to make it work with B4i but no success.
In B4i, when I don't have an image loaded, the click event is fired but once I loaded a Gif file, the click event is not fired.
