Android : Portrait-oriented Menu In Lanscape-oriented View In Droid?
Aug 19, 2010How can I have a portrait-oriented menu in my lanscape-oriented view in Android?
I'm building an application with some items that must be landscape-oriented. Everything else (menu, view for editing the item, list of item...) should change orientation according to the orientation of the device. To do that I set android:screenOrientation="landscape" in the AndroidManifest.xml for the activity showing my items. Now, how can I create a portrait-oriented menu for that activity?
I'm also wondering if setting the screen orientation of the activity is the only way? Isn't it possible to set the screenOrientation for each view?
Samsung I7500 :: Is Programming For Android Completely Different Fron Programming For IPhone?
Dec 24, 2009I have made apps for the iPhone, but want to also code for the Android but want to know if it is first worth my time, second worth my having to learn another language, and third worth the effort in the sense that am I going to make a profit from this. Also if in any way Android code is similar, then will it be hard to bring the iPhone (Xcode) files, or copy and paste my iPhone code into the Android code.

Jan 22, 2010I'm wondering if anyone has figured out yet what the best resolution and/or aspect ratio is for custom contact photos? Most of my contact photos come from Facebook, but some I will edit on my PC and load onto the phone's SD card. I know there are issues with decent photos becoming low-res pixelated, so I'm wondering if I start with the best size and/or aspect ratio, maybe the phone won't have to resample the photos itself.

View 6 Replies View RelatedAndroid :: Using TabActivity In Object-oriented Manner
Oct 7, 2010I'm fairly new to object-oriented programming, and I'm really interested in learning it correctly. My problem is this:I am trying to create a TabActivity which plots the user's data over time in each tab's content. Then only thing the tabs are going to control is the timespan of the graph. (i.e. one tab for 'past year', one for 'past month', one for 'all time', etc). As you can see, the layout used for each tab will be identical. The code used for each tab will only differ by a couple lines... (the starting and ending date of the x-axis).
I'm not sure how I can pull this off in a well-designed, object-o fashion. Any ideas?
Android :: How To Scale An Image In ImageView To Keep Aspect Ratio?
Mar 26, 2010In android, I defined an ImageView's layoutWidth to be 'fill_parent' (which takes up the full width of the phone). My question is if the Image i put to ImageView is bigger than the layoutWidth, android will scale it, right? But what about the height? when android scale it, will it keeps the aspect ratio? What I find out is, there is some 'white space' at the top/bottom of the ImageView when android scales an image which is bigger than the ImageView. Is that true? If yes, how can I eliminate that white spaces?

Jan 25, 2010We can set the pixel values in custom views by multiplying them with

This is ok when the screen aspect ratio is normal means not long
But how can we set the pixels along Y-axis when the aspect ration is long.
Android :: How To Return Non-table-oriented Data From A Content Provider
Mar 27, 2009I'm writing a content provider that returns data about game sessions. This data comes from an SQLite table. However, the client that consumes it will also want summary data: total wins, current/best winning streak, and so on. I'm not sure which approach to use.
* Possible Approach 1: Do nothing, let the client calculate what it needs.
The client could step through the whole table and calculate statistics itself. However, it's inefficient to send the entire database over the content provider link if the client only wants the summaries; this may also be prone to bugs because each client has to reimplement the summary calculations.
* Possible Approach 2: Separate content URIs for summary data.
The client could ask for a URI like content://myapp/summary/totalwins and get back a text/plain stream containing the number of wins. This seems like a big hassle to implement on both ends, though. Or it could ask for a URI like content://myapp/summary and get back an XML stream containing all the summary data, but this isn't much simpler.
* Possible Approach 3: A phony table.
The client could ask for a URI like content://myapp/summary and get back a cursor over a single row, with each summary value having its own column. This would not be an SQLite cursor but a custom in-memory cursor. It seems a little unnatural to use a table metaphor when there's always exactly one row, though.
* Possible Approach 4: The extras bundle.
Cursor has a getExtras() method that returns a bundle. The client could make a request for the main URI, content://myapp/sessions, and then just look at the extras bundle instead of reading any rows. However, there's no setExtras() method, so I'm stuck with whatever bundle object SQLite puts in there - and if it's Bundle.EMPTY, I'm out of luck.

Oct 13, 2010Five years ago I used to program in SAS. Since then I've been doing software QA of various types. Mostly manual (video games + web apps) testing with a tiny bit of automation.
I'd really like to shift careers back into programming. Specifically the Android platform has caught my attention. These are the books I've been reading and working through.
Learning Java, Third Edition - O'Reilly
Beginning Android 2 - Mark Murphy
Hello, Android - Ed Burnette
However, I think I need something that looks at programming from a less language dependent standpoint. Something that takes a bird's eye view if that makes sense.
It's very easy to see how particular functions work, but I'm looking to get a better sense of how all the pieces fit together. How does one split up an app into individual classes and packages? Do I have a method in main that shuffles my deck of cards (object) or does the class deck of cards have a method I can call to shuffle itself?
I think I'm looking for a book on object oriented design? I've also been working through the tutorials and examples at http://developer.android.com/resources/index.html and also in the three books I've been reading so far. Maybe I just need to spend more time coding though?

General :: Change Aspect Ratio / Resolution On MK802 IIIS?
Apr 24, 2013I want to use my MK802 IIIS with a projector but I am having aspect ratio/resolution issues. Namely my projector supports 800x600 and 1024x768 but on my Android stick I get chose 1920x1080, 1280x720 or 720x480 (Settings->Display->HDMI modes). The stick has only HDMI output and I am using a cheap chinese adapter to connect it to the projectors vga input. For example with 720x480 I do get the picture but at left side a slice of it is cut off.
Ideal would be if I could set the video output to 1024x768 (with 4:3 aspect ratio).So, how could I change it?
Is there any Xorg like solution, that is, add resolutions by editing some conf file?I should create a custom ROM, build custom firmware...

Android :: How Much Java Should I Have Learnt Before Trying Droid Programming
Jun 5, 2010I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet?
Of course I can keep going in Java, but have been itching to begin programming Android apps.
Any definitive answer here about how much Java I need to know before Android?
General :: Allwinner A20 Tv Box - Change Screen Res / DPI / Aspect Ratio - System GUI Always Stops
Mar 23, 2014I have an Allwinner A20 tv box, I trying to use it on a device with an old, low res, 4:3, 5" screen. It works but I have a few problems - firstly the box has "pal" and ntsc" settings for use with AV out, but when connected the picture is squashed inwards so circles are represented as ovals. I ve tried to mod the aspect ratio/resolution but nothing works, the picture is always distorted.
On top of that everything is too small for the screen, it is readable but things really need to appear bigger, so I also played about with the dpi, this does make things bigger and a better match for the screen, even though the device doesnt actually have a screen itself.
I ve done both these mods with several apps and modding the build prop and I always get "sorry systemGUI has stopped", constantly - when you close it, it opens again straight away. Clearly settings doesnt like these mods, so I m trying to work what I need to change so it DOES accept them.
How I can successfully mod the setting.db and get this working at the correct aspect ratio and a dpi that is suitable for use on a low res screen ?
