Android Question reuse Activity

[SamuelP]

Hello,

in my main-Activity I use this code:

Sub listview1_ItemClick (Position As Int, Value As Object)
    CallSubDelayed2(Monatseingabe, "SetKlient", listview1.GetItem(Position))
End Sub

This should (and does) show the "Monatseingabe"-Activity and fill it with data from the database.
When I hit the back-button to return to the Main-Activity and to select another listview-Item, the Monatseingabe-Activity is completly loaded agin (needs long time because it contains a lot of labels).

Is there a way to keep the Monatseingabe-Activity cached? So that I only have to change the content of the views without loading them again?

Samuel

You can use two panels in the Main activity and set the visible property to False and True.

Do you mean I should use two panels instead of two activites? This would mean, I can use only one bal-File?
Is there no other solution ?

Yes they are options : not caching the Activity but the variables used to fill the views. Services (and especially the Starter service) are useful for that task.
For example : the list that fills ListView1 could be created in a service and applied to ListView1 in Activity_Resume.

Note: myself, I do often use a Process_Globals list variable associated to an Activity Globals list variable where I put the Activity's views to be able to manage them directly from inside the services. But that's a bit tricky, not clean at all and outside the range of that simple task (see previous paragraph)

Yes.

No ! You can use two layout files one for each Panel.
