Apps I'm not sure how to refresh an activity with new information.

I have several textviews in an activity. I then have a button that I want to be able to click that will update the textview.

I want to do this without having to create multiple activities.
How do I go about I guess refreshing the current screen with new information?

I was thinking that using something like TextSwitcher was the answer but I can't really find any good examples of it.

Where is the information coming from?

The information is coming from the current activity. A method in that class does the calculations and I just want to be able to keep updating the activity with the new calculations whenever a button is pressed.

in your onClick() method, just reperform the calculations and then set the text of the TextViews to the new values.

Cool that works.

I thought I had tried that before and it didn't work. I think it's because I was telling the button to go to that method in the xml file maybe? Instead of using the onClick() method

I was just doing androidnClick="method"

Or should both of those do the same thing?

 

[jonbonazza]

in your xml method, do you also set the text of the textviews or is that done outside the method?

 

[emblemboy]

I set the text of the textview in the method where I do the calculations.

Hmm.. Odd.. I am not sure why the xml implementation didn't work then. at any rate, I prefer the code implementation anyway.
