Android Question Keyword Cloud

[ykucuk]

I'm currently working on a project where I need to incorporate a keyword cloud, similar to the one pictured in the attached image. I've been looking for suitable libraries to create this, but so far I haven't been successful.

Could anyone provide me with some guidance on how to implement this?

You could use a free word cloud generator, such as this website, download the output image and show it in your app.

I want to do it in B4X.

Yes you can:

Sub keywordsCloud
    Dim lst As List
    lst.Initialize
    lst.AddAll(Array As String("Erel","B4X","Hamied","Newyork","Sana'a","Dubai","ykucuk","toby","Egypt","Frankfourt","Erel","B4X","Hamied","Newyork","Sana'a","Dubai","ykucuk","toby","Egypt","Frankfourt"))
    For i=0 To lst.Size-1
        Dim lbl As Label
        lbl.Initialize("")   
        lbl.TextColor=Colors.Green   
        lbl.Text=lst.Get(i)
        lbl.TextSize=Rnd(8,30)
        Panel1.AddView(lbl,Rnd(0,Panel1.Width),Rnd(0,Panel1.Height),100dip,40dip)       
    Next
End Sub

Curious...

1. Are you talking about a general algorithm to create these clouds on the fly?
2. Are you planning to develop a library for this yourself?
3. Are you aware of the complexity involved?
- the science of creating metrics for 'importance'
- the science of optimal packing rectangles in a rectangle or oval
- the art of composition
