Android Question selectively hide edtxt i/p

[Laurie]

I have an array of edtxt.text boxes in a scrollview.
Is it possible to selectively make some of them invisible?

 

[Andrew (Digitwell)]

Yes it is.
You will need some way of identifying the views you want to make invisible, maybe hold them in an external list.
you can then do something like:

...
for each ed as b4xview in listofviews
 ed.visible = showthisview(ed)
next
...

private sub showthisview(ed as b4xview) as boolean

'    return true or false based on some criteria
end sub

Did you want to also hide the gaps? It may be better to use a CustomListview rather than a scrollview.

I had been trying to use
EdTxt.Visible=False
within a for next loop

That didn't work, but isn't your suggestion essentially the same?
Also within the loop were (non input examples) par(i).visible=false which works fine??

Not exactly, the key was the line, hold them in an external list.

Take a read of this for pointers.

[B4X] I need 100 <custom view here>s. How to add programmatically?

Custom views are designed to be added with the designer. It is however very simple to create a layout file with the custom view and load it multiple times. Tip: remove the call to AutoScaleAll from the designer script. Complete example: Sub Globals Private B4XSwitch1 As B4XSwitch End...

The key thing to remember is that if you load a layout multiple times, the variables only point to the last instance created, which is why you need to create a list of them on creation.

Don't waste your time with ScrollView. Use xCustomListView. It is based on ScrollView and it adds many useful features. And it is cross platform.

Ok, thank you both for your suggestions - I'll get down to it.
