Android Question A question asked by an expert beginner ^_^

[LucaMs]

Since I have not used actionbars (I used B4A as if he were VB.Net )

I have a "nice" Exit button in every activity, which, in reality, is a "back".

So, to return to the Main, sometimes the user must repeatedly press "Exit".

In some activity I could add a "Home" button or "Main", but in this case, what do I do? One startActivity (Main) (including Activity.Finish in the current one)? Do not remain suspended all previous calls to the acitivities?

If you're finishing activities every time you enter a new one, then there should be no problem at all.

Ok, many thanks mc

When I go from one activity to another I rarely use Activity.Finish because in most cases I want to go back to the calling Activity and for this the Back button of the system does it, no need for an extra button. This is the 'standard' way Android works.
I use Activity.Finish only when I don't want to go back to the calling Activity.

I "locked" the back button on all the activities.
Sometimes the user wants to go back to the calling, sometimes he might prefer to go at the main;
I wanted to ask if, in this second case, I could have execute StartActivity(Main) without affecting anything (probably there will be a queue of calls)

In the second case you can have a button and use in the Click event.
Activity.Finish
StartActivity(Main)

Activity.Finish
StartActivity(Main)

Yes, thanks Klaus.
May be i'll decide to change all and use an actionbar (but, thinking, i'll must do the same, lol)

Klaus, does that work ?

I mean, can we have the activity.finish and code statements ater that will execute ?

I never actualy tried it, as I thought it wouldn't work

You're right, it seems very strange, a Start something AFTER activity.finish, but it works!

always learning...This will come handy in a lot of situations I can see.
