Android : How Might One Create A Large Bitmap In Droid

Aug 10, 2010

I am trying to build an Android application which can take several photos taken by the camera, and merge them into one giant image. For example, I might take three photos and arrange them in a vertical stack for output as a single image. Ideally, I'd like to be able to keep the images at the original size. Unfortunately, using Bitmap.createBitmap() causes an OutOfMemoryException before even approaching the size of one photo of camera dimensions. Is this possible? Or do I just need to resort to scaling the photos before trying to merge them into a single Bitmap?

Android :: Moving Background Image For Game

Nov 11, 2010

I'm currently developing an Android game where the user controls a plane and evades obstacles. I'm using simple draw commands into a Canvas.

I want to know what is the best way to move a background image to give a sense of speed to the game. Is there a way to make the background- image repeat endlessly or should I load the image twice and move them one behind the other one. Can anyone guide me on this one?

Android :: Draw Background Image With Moving Foreground Graphics?

Aug 28, 2010

I would like to know what the best way would be to draw a background image (this would be pretty much static) and a foreground object which would move depending on user input in Android?

Sort of like a side-scroller game (when the foregroudn object needs to animate and change a lot more than the background).

Android :: Moving Cursor Adapter Cursor Creation To Background Thread

Mar 29, 2010

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

Android :: Create Background Loop Method

Aug 31, 2010

I want to call a method every X minutes, if my method got a result it ´should inform the user by vibrating or showing a alertbox. if the method doesn't get a result it should wait for X minutes and restart. What is important, this should also work when the phone turns to sleep. Which means I want to wake the phone from sleep to run my method. Actualy I can activate my method via a Button, and it is working like I want it to be except the background loop thing.

I already searching for a solution here in the group or also on google but I think I don't got the right search terms to find a solution for my problme. I already read about the AlarmManager and broadcast receiver but I'm not sure if this is right for my problem.

Android :: How To Create Toast From Background Operation?

May 1, 2009

what is a good way to signal an error from a thread that is not the UI thread and you don't know which activity/handler is currently active? Can I somehow get eleto the current UI thread? Can I somehow use the MainLooper from the application context? I use notification for serious events where the user needs to take action, e.g. a login failed, but here I am looking for a transient notification with a toast and it would be ok if the toast is not seen in some cases.

Android :: Create View With Background That Wraps Up All Content?

Mar 5, 2009

I'm trying to create a listview containing conversations in chat bubbles, and each chat bubbles are rows in the list view. So what I have is an avatar on the left, and a chat bubble on the right. Then in the chat bubble, I have a textview for name, a textview for content, and a textview for time. The problem is, I cannot adjust the height of the chat bubble such that the bottom edge is just below the textview for time. In the chatBubble, I have this line that does not work android:layout_alignBottom="@+id/timeLabel" because timeLabel is a textview created after chatBubble. If I place chatBubble tags right below timeLabel, the height of chatBubble will be just right because lf the layout_alignBottom, but chatBubble covers all the text created before it.

Is there a way I can create the chatBubble last, and bring the view to the background? Or is there a better way to do this?....................

Android :: Need To Create A Background Service That Listens For Actions

Aug 26, 2010

I'm new to the android platform, and I need to create a background service that listens for actions from different applications, the home activity, menu items in different apps, etc. Is it enought to call several event listeners and pass the different home activity events (and events from other activities) to the listeners? If so, what exactly to I pass to my event listener? Is the home activity an object that I can call? What is it and how do I pass it? Otherwise how to I listen for user interaction with variouse elements of a given view/activity? I need the listeners to trigger an activity that occurs before the event they asked for. For example. 1. They press the arrow button on the homescreen. Before it pops up, a picture pops up on the screen.

Android : How To Tell A Finger Is Down On Screen

Nov 17, 2010

I understand calling onTouchEvent from views to get the location of the last touch as a motion event. How the heck can I tell that a figure is down on the screen and has not been lifted and when the finger is lifted?
For instance there is onKeyDown and onKeyUp for use when you are dealing with keyboard input. So how can I find out when on fingureUp happens?

Android : Detect Finger Going Off Screen?

Jan 3, 2010

I have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.

How can I detect that the user's finger has left the screen?

I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.

Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?

Android : How To Switch Between Views Following A Finger

Apr 15, 2010

I can't find a tutorial on Google for my problem. I'm french and i don't find the best "google keywords" for to describe my goal. I decided to ask the question here.

I want to do an animation between views like on the Home or on the Calendar in week mode. I want the switch between the views follows the finger. As I have not released the pressure, I see a part of the current view an a part of the next view.

Currently, I use a AnimatorView and 2 gestures. But the change happens when the pressure is released, and it's not good.

Can someone explain to me how to do or where to find a tutorial that explain? ps : please, don't laugh about my english, it's worst when I speak with my very french accent :P

Android :: Enable Fingerpainting Not Only With Finger Touch

Nov 11, 2009

I was checking the possibility to allow painting on the screen of a surface (i.e. API demo Fingerpainting example), however when I checked it, this technic apparently only allows painting with the tip of your finger, if you try to use any other object (pencil, thick pen, etc.) it does not draw anything on the surface. Am I missing something here? Is there a way to allow other objects to draw things on a surface? Is this achievable and how should I proceed?

Android :: Logic Different Between Using Keypad - With Finger Tapping?

Jun 19, 2009

I have a ListView. When I click a row Item (which are just TextView instances) I want them to remain hilighted (default orange color). The default behavior is that they flash orange.

Strangely, if I use the key pad (arrow up/down) to move between items, it has the exact behavior I want. Why is the logic different between using the keypad or with finger tapping?
