I'm having trouble creating a layout with two backgrounds that tile in the x direction but not y.
I've mocked up what I'm trying to create here...
http://img153.imageshack.us/img153/6008/cnbackground.png
So the top section repeats horizontally, then there's a flat creen section in the middle in which I will center my content, then there's some horizontally repeating grass along the bottom.

I am trying to launch an activity from another activity .. Within the com.android.SingleLauncher..
I have activity launch code as ..
CODE:...........
I have set the android:multiprocess="true" in the AndroidManifest.xml of TargetSL I don't seem to see the multiple instances of TargetSL, which i am expecting ..
All i see is 2 process, where i was hoping to see an instance of TargetSL, for each launch that was invoked by the singleLauncher!
Any programs to change the background of the phone every few days automatically?
View 5 Replies View RelatedI have two questions about wallpapers on my nexus one. First off, is there anyway to take a custom image that I have and I am using and put it into the list of "default" backgrounds so that when I change it I don't have to go through that resize hassle and everything and I can have it in a more organized location. Also are there any applications or tools out there to get great looking wallpapers for the nexus one. Sometimes when using an image it doesn't look that good and the selection thing when doing it from the gallery is annoying because of the selection has to be a square yet my screen is 800x480.
View 2 Replies View RelatedAre 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?
So I have an app with Activity A. The layout on the activity is dynamic genearted. So it's possible that on Activity A a user hits a button that goes to "A" and the new page looks different, then a user clicks another button to go to "A" again. Now I have 2 Activities in the history stack. A, A, and currently on A. Is it possible that if a user clicks a button that the whole Activity stack is cleared in a scenario such as this?

It seems that they store preferences as "default" preferences only. I would like to use a PreferenceScreen as my configure activity for an AppWidget, but I need to be able to store distinct preferences for each widget.

View 1 Replies View RelatedI want to create multiple instances of an activity in the same process. Should I use FLAG_ACTIVITY_NEW_TASK flag like the code below?
CODE:...............
This code is executed in class A to create another instance of activity A.
This question, will this code create another task? As I understand is a process can only have one task. Does it mean the two activities will exist in different tasks? That's what I want. I want the two activities to be in the same process.
I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity.
I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack.
Could this be from both onPostExecute()s executing simultaneously and both checking the flags each other set at the exact same time? This seems extremely unlikely since two processes would have to be running line-by-line in parallel...
A lot removed from this question since I was way off in what I thought was wrong. Nonetheless I found the answer here quite useful, so I have edited the question to reflect the useful parts.
I want to have multiple listviews in single activity. But only one listview should be displayed at one time. The listviews will be loaded dynamically. So, how can I fill all the four listviews at the same time and display only one?
View 4 Replies View RelatedI have been trying to get a specific layout for more than two days now and really struck with it, what am trying to achieve is: To have a layout like the following
LISTVIEW A

LISTVIEW B

LISTVIEW C
(VIEWS are basically for headers) Can any one help to sort out this task?
I want to have multiple listviews in my activity. Every listview will have a different adapter and every item in the listview must be clickable (other actions for every listview).
So my problem now is that I can't create multiple clickable listviews. I have one listview like this <ListView android:id="@android:id/ list".. and the other listview looks like this <ListView android:id="@+id/ flightList"
The first listview looks like this in my activity hotelList = (ListView)findViewById(android.R.id.list);
the second: listView = (ListView) findViewById(R.id.flightList);
I can click on the first list and it does what it has to do, but i cant do anything with the second list.. probably because it hasn't the android:id/list declaration. does someone knows how I can solve this problem or other suggestions how I can get multiple lists in 1 activity.
I've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handleMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? Code...
View 1 Replies View RelatedI was wondering is it possible to create multiple instances of a single Activity in Android?
I currently start my own inCall screen for a Voip Test by using the following code...
This allows me to start the Activity fine. However when I call it for a second it just returns to the Activity already created rather than creating a new Activity and placing it on the stack.
I would like to be able to create the activity multiple times so that I have two or 3 Activities on the stack and the user can switch between them, using Home, Back buttons etc... Is this possible and if so what am I doing wrong?
I want to know if we can display multiple activities in a single activity using ActivityGroup.Can anyone please help me out with this?
View 1 Replies View RelatedI 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.

View 12 Replies View RelatedThis question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnable. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ?
I'm new to Android.My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data).
My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide.
I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method.The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this.
A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completely new, so I lose information about currently sending images and so on. How I could design in a appropriate way.

I added an intent filter to one of my activities, so that when a user clicks a URL like "www.mysite.com", and if my app is installed, my registered activity can be launched. It works well.
I see that this creates a new instance of my registered activity though, every time a link is clicked. Is there any way to prevent multiple instances from being created - just recycle an existing instance if one already exists?
I'm struggling with my app that launches multiple instances of the same Activity using the same intent. My main activity is of class type A and it does a startActivity() of two children that are of the same class type B. So we have B1 and B2 launched. If B1 and B2 are both paused (by pushing back button and making sure finish() is not invoked on them so they are truly paused), how can A uniquely bring either B1 or B2 to the foreground again? I do want to launch a new B activity. I want to uniquely bring B1 or B2 to the foreground.
so both B1 and B2 were created like this... Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);
Now I want A to bring B1 (or B2) to the foreground/front so I use the below code, but how do I distinguish B1 or B2 when starting the activity? This only brings the last instance of B that was on top to the foreground.
Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivity(intent);
I've tried keeping around references to B1 and B2 and doing something like this, but this also only goes to the last instance of activity class B that was on top...
Intent intent = new Intent(B1context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); B1context.startActivity(intent);
I even tried this, but it still doesnt get me my unique B1 or B2... Intent intent = B1.getIntent(); // i.e. the original intent that started me startActivity(intent); // still only brings to front the last B that was on top.
I downloaded AK Notepad because I needed an app to quickly jot down things, and it also came with an alarm, which is nice, but it only alerts you one time with one little noise. First of all, is there a way to change this to a repeating alarm? If not, what is the best app for an alarm clock that continues to ring after 1 ring?

I'm trying to run a background task which runs every minute or so for an android application but I am struggling to ensure that the task actually runs every minute. I've tried a variety of approaches from using SystemClock.sleep() to the AlarmManager (both repeating alarm and a fixed alarm) but it seems that unless the device is charging any kind of repeating system has a variable repeat rate once the device is unplugged. Is there any way to run a stable consistently repeating service?
