[android-developers] How to mark an element visually in ListView the user clicked on?
I have a ListView with a custom adapter. I'd like to visually mark the list element the user clicked on by changing it's background permanently (until the user clicks on another element that is). How do I achieve that? I believe that there's a built-in feature inside LisView for this, but I had no luck finding it yet. By default ListView animates the background color of the list-element clicked, I just want that modified color to stay. I've already set the ListView's ChoiceMode to single choice, but it doesn't affect it visually.

[android-developers] Re: How to mark an element visually in ListView the user clicked on?
Thanks, I was looking for this 'activated' state. The methods and states related to selecting elements from the list completely confused me. It turned out that the in ListView's context, selecting an element means that the user navigates the focus around in the list with the d-pad... And yes, I'm using Honeycomb, so my list needs to stay on screen, and display the previously selected element. So currently I'm setting the selected element's view activated, and assigned a custom selector with a distinct background color for the activated state for the row's layout.

On Honeycomb, your desired look is achieved by setting the activated state on the row Views. On phones, since the ListView is not usually on the same screen as other stuff, your desired pattern isn't really part of the framework.

Welcome to the club. Several threads were discussing this problem, without any result. At least someone from the Android dev-team could tell us that it's a know issue, or whatever. Quite frustrating.

[android-developers] FragmentPager component?
During the Android 3.0 UI design talk on IO 2011, it was mentioned that we'll get a FragmentPager component soon. I'd like to know a bit more about this component, when'll this be released and what'll it be able to do? I'm quite curious, because it awfully sounds something that I'm working on right now. Is it about some kind of left-to-right fragment paging mechanism that's used in the Honeycomb Gmail app? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Fragment animation as in Honeycomb Gmail app - how to do that?
I'd like to achieve similar fragment behaviour as in the Honeycomb Gmail app. So I have three fragment next to each other: A, B and C. Initially, A and B is displayed, and when the user selects something from B, it triggers an sliding-animation/fragment-transaction so that B and C are visible. B showing the selected item, C showing the desired content. Any ideas how the Gmail app does this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How does the ActivityStack behave when it contains thousands of Activities?
In my app I have a about a dozen of different Activities. These Activities are connected (can call each other with startActivity()) in such a way, that the user can theoretically keep running in circles - always jumping to the next Activity, never going back. Also, I really need to maintain a proper Activity history: if the user presses the back button, the app returns to the previous Activity, with the previous content. Question: Suppose the user's using the app for an extended amount of time, going in circles between Activites as mentioned above, resulting an ever-growing ActivityStack. Every Activity saves some state on onSaveInstanceState() too. - Is this a problem? (I'm afraid it is, I guess it's a memory leak to have tens of thousands of Activity records on the stack, especially if these save their state). - Is there a way to limit the size of the default Android ActivityStack's size? (size limit is X, we delete the oldest record if it gets filled up) Any suggestions / alternative solutions are welcome. -- You received this message because you are subscribed to the Google Groups Android Developers group.
