Android Question Switching Activities

[Paul Boyle]

Newbie here.

Just cant get the hang of these activities commands.

In VB.Net if i press a button on a form and it loads another from I can code something like

OldForm.Hide
NewForm.Load

What's the equivalent of this using activities in B4A ? For e.g.. if I have an Exit button and want to hide/close the current activity and open the main activity?

Many Thanks.

Suppose your button is in the main Activity and you want to pause main and go to the second activity. If the 2nd activity is called Boyle, you do this:

Sub MyButton_Click
      StartActivity(Boyle)
end sub

First layout loaded is:

'Load Layout
Activity.LoadLayout("lay_Home")

I hit a button on this activity, it triggers:
'Load Layout
Activity.LoadLayout("lay_Plyr")

I then hit a button (Exit_Click) and want it to close "lay_Plyr" and go back to "lay_Home". This is where its not working for me.

What is the ponit of asking some really basic if you dont even know how an Android App works?

First read the Android Process and activities life cycle

Then, all the basics are covered here

Look at chapter 13.2 Program with 3 Activities (ThreeActivityExample.b4a) in the Beginner's Guide.
Look at Two activities example.
Look at Different examples with 2 layouts.
