Android Tutorial Setting value for a text label

Hi,

Sorry for the silly question.

I have created a layout with a single label called jbox.
I simply want to set the text of the label in the program but cant seem to do it.

My code ..

Sub Activity_Create(FirstTime As Boolean)
activity.LoadLayout("Layout1")
jbox.Text="test"

When I compile, it complains that I am using a varible without setting it?

Help!

Many thanks.

Jason

just define jbox

dim jbox as label

You can also use the Generate members tool to do it.
See the IDE tips tutorial: http://www.b4x.com/forum/basic4android-getting-started-tutorials/6546-ide-tips.html

Thanks for your replies - all sorted now.

I wish there was a consolidated manual for this, its hard to find the right information when it is spread around so many different pages etc.

Cheers,

Jason

In the meantime I recommend you to start with these tutorials: Basic4android - Android programming with Gui designer

I just had this same problem, and indeed defining the view (eg dim jbox as label) within Activity_Create solves it. However, I had already previously used the Generate Members tool, and the declaration already appeared in Global. Why was that declaration not relevant if it was already a Global declaration?

There is no need to redeclare a variable that is already declared in Sub Globals.
I'm not sure what exactly happened in your case. You can upload your code and I'll check it.
