Question

This might be a general mvp places and activities question, but the show case I’m trying to understand here is this gwtphonegap-showcase-gwt example.

How do I pass a parameter to a view from another one?

For example, let’s say I want that when a user clicks on any cell on the OverviewActivity, it will take them to the same place everytime (AboutPlace), but the text should be different (let’s say it contains the cell number).

I added a setText(String text) to the AboutDisplay interface with the corresponding label and setText() in the AboutDisplayGwtImpl, but I have no idea where to call it. I tried calling it in AboutActivity start() method and ClientFactoryGwtImpl getAboutDisplay() method, but they seem to be called only once when the app first loads, so I end up with the same text each time.

Answer 1

you should not use a view directly for that.

You can add a field on a place and set your value there and access the same value in the next activity.
