Anyway to append to the activity stack without doing a StartActivity?

I would handling the back press. Just use a flag within your activity that tells you in which view you are (so back within the detailed view shows you the overview view) Another way would be to save the values in your applicationContext. Much easier way to do it than database usage.

Take a look at an answer here: Android: How to declare global variables? But I would definitely go with handling back presses. I have a solution similar to this where I use the same listview in the layout and instead I use different adapters depending on which detailed view the user is in.

BTW. I went ahead with the back button solution and a history manager implementation to do a user friendly back action implementation. Will post these details soon.

Thanks for your reply – mays Aug 3 at 14:21 Sorry, but I have updated that code and removed that. I had a boolean variable to know which view I was in. Overriding the onKeyBack I just checked the value of that variable and either quit the activity or change the adapter by just putting listview.

Handling back press is the easiest way to go. Else you could also pass the information to view as Intent extra to the second activity. Another possibility is to have a local service running in the background and in charge of loading your XML and offering access to its information in a convenient way.

You can also stuff the XML content in an Application object of your own. However I have had not so great experience with that option in some projects.

Calling a new activity means parsing the xml again for the app. I would love to avoid that. – mays Jul 21 at 13:24 Answer edited ... – MarvinLabs Jul 21 at 13:58 offering access to its information in a convenient way -> do you mean caching it on a static member?

Any other ideas? Stuff the XML content -> not a possible option for this project – mays Aug 3 at 14:18.

I would use a second activity. Pass additional data (like contact list, message details, etc. ) to it and display it. How you keep parsed XML in memory is up to you to decide (static member?

Yuck! But it works). Now back to original Activity.

Does your source XML change a lot? Maybe you can parse it and put all data into a DB so that you could retrieve necessary (and hierarchical) data quicker. This way you do not need to deal with storing lots of data in memory, re-parsing and you could perform search faster.

Didn't want to do the second activity, also the DB approach. Settled with the layout hide/show and back button approach. Thanks for your reply – mays Aug 3 at 14:22.

On click event of this list I don't want to load a new activity with a bundle, parse the same xml and show detailed view, while I have the required data in activity A itself. Cache the parsed XML in a static data member. Your activities that need the data look at the static data member first, then kick off the parsing if and only if that cache is not there.

IOW, this is not an activity problem, but a data model problem. Do a better job with your data model, and your activities can behave naturally.

Agree with this. Looks more like a data handling problem. Also using another activity may be better IMO.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
