Android :: Multiple Screens In One Activity Like Home Screen?
Oct 9, 2009
I am working on an application where I wish to have multiple screens (each of full display size) attached to each other horizontally, and switch between them by using the finger (swipe right / swipe left). The home screen does exactly what I want, but its implementation seems to be more complex than I thought. What would be your preferred way to achieve this functionality? Is there any Layout or View that I could reuse? More generally, it should work with the 1.5 SDK, so the gesture interface is not available.

Two things I'd like to be able to do with my incredible.First is reduce the number of homescreens. Seven is really pointless for me, it makes finding the right screen take a little longer and there's just not enough good quality widgets that I need to use. I could do better with 5 and possibly just 3.Second is that when I'm not on a homescreen and I hit the home button, I'd like it to go back to the LAST homescreen I was on, not the center one. And if I'm already on a homescreen, once again pull up the homescreen select menu, instead of going to the center homescreen. It's a waste of a button press to always go to that center screen when pressing the home button.

Is there any way to disable the screen that shows all the 7 screens after tapping the home screen? If not disable get rid of it all together.
Or maybe an app to do so?

is there a way to move the icons without having to remove them and then pick a new place? If not - why with the nice slide functionality, can you not just slide them around on the same screen or the the next?

Most of my time with my new precious has been obsessing over how to arrange my screens.
Why the flip do the widgets lock into such ridiculous places!? Sometimes you could fit a whole other line of regular icons in the space that they leave!
So my question: Do any of you have OCD about how the screens are set up, and how do you set it up to work?

It's nothing special but I got my 5 Droid X home screens set up, for now, using LauncherPro and figured I'd take capture a few screen shots. I like to keep everything simple and clean with apps put in seperate "sections" without having a bunch of widgets in the way. Feel free to ask any questions and if you want screen caps of certain things let me know.

I had a little time with the captivate today and noticed it has 4(i think) horizontal scrolling screens for apps. What happens when you fill those? Does it automatically add another one or what?

I'm trying to do something which really ought to be quite easy, but it's driving me crazy. I'm trying to launch an activity when a home screen widget is pressed, such as a configuration activity for the widget. I think I've followed word for word the tutorial on the Android Developers website, and even a few unofficial tutorials as well, but I must be missing something important as it doesn't work.

I am desperately trying to get my head wrapped around how to implement home screen widgets. Right now, I (finally) was able to get a button on my widget respond to a button press setting up an intent filter in the manifest.
However, I cannot for the life of me figure out how to launch an activity when the button is pressed. Basically, here's the code i have...
What I really want to do, though, is start a new activity, not display a toast message. I know it has something to do with pending intents, but I can't figure out how to get that to work.

I have a widget that when clicked opens an activity from same app as the widget. When the activity is closed/dismissed via a button, the user will see the full app window IF the app was previously open/in memory. Is there a way for the activity to finish and return to the home screen and not to an existing instance of the app?
Intent i = new Intent(this,RateIt.class);
i.putExtra("com.sporadicsoftware.NetQ.movie_id",aMovie.title_id);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET|Intent.FLAG_ACTIVITY_NO_HISTORY|Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context,
0, i, PendingIntent.FLAG_UPDATE_CURRENT);
updateViews.setOnClickPendingIntent(R.id.movie_one_title, pendingIntent);

I'm writing program for Android (SDK 1.5). I would like to know how to add/register one of my program activities in "Home Screen -> Menu -> Add-> Shortcuts" (or on Hero "Home Screen -> Menu -> Add to Home-> Shortcut") so that user will be able to add it to his home screen. Is there an Intent Filter or any other way to achieve that?

I am getting my feet wet developing software for the Android. My test app will have multiple screens (each having their own layout file). The main screen will direct the user to view the other screens based on user input. I kinda see this as layers of cake. Bottom layer being main; then you add and remove layers as the user makes UI inputs. The crazy trouble is how to view a second layer. I have created a second class which has its own onCreate method, which has its on setContentView(R.layout.secondlayer).
This class extends Activity much like my primary class does. I have a click event on a button within the main layout. This button will instantiate the new second layer class which I have done. And that is where my story endsI don't know what to do from this point. This is surely a newbie question If someone has an example that would be extremely helpful teach me to fish and I will be on my way.

Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.
I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.
What advantages of multiple activities am I missing?

Has anyone been successful showing a notification, starting an activity, or loading the home screen *during* a call on the Droid? All three of these actions can be done with the emulator running 2.0, but will not run from the Droid. I don't receive any type of notification that these actions fail on the Droid. Although, every action works when a call is *not* active. Missed calls during a call *do* show up in the notification bar, so I am hoping there is a way.
I understand that the notification bar can not be accessed by users during calls, but it would be nice if a notification could at least be delivered. I also understand the security and usability concerns of displaying a window or action during phone calls. Although, there are a lot of users who would like actionable functionality based on calls.

In the Supporting Multiple Screens document in the Android Dev Guide, some example screen configurations are given. One of them states that the small-ldpi designation is given to QVGA (240x320) screens with a physical size of 2.6"-3.0". According to this DPI calculator, a 2.8" QVGA display equates to 143 dpi. However, further down the page the document explicitly states that all screens over 140 dpi are considered "medium" density.
So which is it, ldpi or mdpi? Is this a mistake? Does anyone know what the HTC Tattoo or similar device actually reports? I don't have access to any devices like this.
Also, with the recent publishing of this document, I'm glad to see we finally have an explicit statement of the exact DPI ranges of the three density categories. But why haven't we been given the same for the small, medium, and large screen size categories? I'd like to know the exact ranges for all these.

Could it be possible to make each screen have a different wallpaper while scrolling? I mean, taking as an example a case with three screens, it will be necessary to set a x3 screen width wallpaper to fit 1/3 on each screen, or directly setting different images for each screen. so the scrolling make it visually a different wallpaper on each screen rather than sliding the wallpaper a 50% each side.

I am working on an Android project where a group of buttons needs to show on the bottom of every screen (activity) in the application. The group of buttons are basically a navigation bar. I want to know the best way to do this without creating new buttons for every activity. I have been around programming (C++/C#) for many years but am pretty new to Android and Java so if someone can point me in a general direction.

I have read the topic about supporting multiple screen size as well as different DPI. I am wondering which of the following way is better in supporting multiple screens:
1. Have different layout for different screen size (stretch the images)
2. Have different set of graphics for different screen (use the same layout)
3. Have different set of graphics and different set of layout for each of the screen
Which way is the easiest? And which way is the most optical way to design? Or is there another better way?
