I have a regular layout file : Res/layout/test.xml
And another layout for tablets : Res/layout-large-land/test.xml
This line is used in my Activity to declare the layout : setContentView(R.layout.test);
I'm using an Eclipse AVD emulator with the customer resolution of 1024x600 (Which according to the android site is a standard 7-inch tablet size). I've declared in my Manifest <supports-screens> with both normal and large as "true".
My problem is that the layout is always the original one, the different, larger layout never gets shown (even though the conditions would suggest it should?). Essentially the difference is the regular layout is a ListView and the large landscape one is a Table.
I've tried finding examples of how to get this online and in text books, but I can't find any that show what else to do. From what I've read, Android should make a conscious decision to pick the layout-large-land file over the regular layout one?
Thanks in advance for your help.
EDIT: I've been playing around with the layout, I've tried layout-land (which works fine), and changed the resolution of the emulator to be 854x480, still with no luck.
A simple solution might work for you:::
change res/layout-large-land to res/layout-xhdpi.

I am getting very confused on how to support all different Android screen sizes. I have already checked this answer, this site, the official documentations and many other answers but still I am confused so please don't mark this as Duplicate.
I already created layout-sw120dp, layout-sw160dp, layout-sw240dp, layout-sw320dp, layout-sw480dp (I only need to support up to 6 inches so I don't create layout-sw600dp).
What do I have to do is just have one layout and just copy it in each different folder so Android will do the selection on its own or I also need to change values in each layout?

You start by deleting the layout-sw120dp, layout-sw160dp, layout-sw240dp, layout-sw320dp, and layout-sw480dp directories that you created. Or, at least, ignore them for now.
You then start implementing your UI, putting layout resources in res/layout/.
Then, for those layouts that need to be different in certain scenarios, you then create a directory representing the size when you want a different layout. Copy the layout from res/layout/ into the new directory, and then modify that copy to reflect whatever changes you want.
In other words, one copy of every layout is in res/layout/, and you override where needed with additional, modified copies in specific directories where you need the UI to change.
If you want to use the same layout for each and every screen density, you don't need to create different folders. Use just one simply called "layout" and the system will interpret it for every density. However, this could lead to strange layouts on certain physical devices depending on their screen size and density...
Another point you have to be aware of, if your application supports orientation changes, is that you have to design layouts for portrait and lanscape orientations. This is done by duplicating a folder used for a density and add "-port" or "-land" to inform the systen which one must be used according to the actual orientation of the device your app is currently running on.
If you want to precisely define your app look and feel, you have to customize your layout for each density. And if you use bitmaps, you will have to customize them either (for example, your app icon should be defined with different sizes to keep a good looking for each screen density). Just as for the layout, you have to create "drawable-..." folders to contain the corresponding versions of your bitmaps.
This is an answer that's been an issue from old ages and for which you'll see lot many answers but which is not a one fit all type still. What I did come up with though when faced with the same issue was to use PercentRelativeLayout. This is a relatively new feature that was started from Android support version 23.0 (android sdk manager), and one of the big game changers according to me, since it allowed
developers to specify their blocks relative to the layout size Percentage-wise. And since it is in terms of percent, this fits all screen sizes with varying dimensions, but while maintaining the ratio.
Ofcourse this method involves some trial and error and a lot of experimenting, but I found this method to be the easiest to implement and which took out the headache of maintaining the dimensions for various screen sizes.

I'm working on the layout of an android application. But I have a question about the layout. Once i have created a layout and then go to another screen (for instance 4 inches to 5 inches) all my buttons and text boxes are messed up..
Is there a method to make everything static, so that my layout works on every mobile phone..
What kind of layout are you using, could it be RelativeLayout? that might be your problem in this particular instance.
Anyway, in android there are many screen sizes, each of them you should handle with different layouts depending on orientation, size and density. There is no magic formula as far as I know, but 9-patch images can help a lot. Another thing you should do is make sure that you understand how match_parent and wrap_content values work for height and width.
Check this out: Suppoting different screens
You have to create folders for different types of screens take a look at android developers training
This document contains everything you need.
Instead of having everything fixed, it shows how to design a layer that adapts to the various screens you may encounter.
I have three layout files for an activity:
layout-small-ldpi
layout-normal-mdpi
layout (for the rest)
When visiting the activity with a normal-hdpi mobile, Android pulled the layout from normal-mdpi/. Then I put the generic layout into a new configuration: layout-normal-hdpi/ which seems to do the trick of pulling that layout for sizes>=normal && density>=hdpi. It also seems to pull the normal-hdpi layout with devices of large-mdpi configuration which is fine by me.
Will this solution cause me any troubles? Is there any better way for keeping the number of layout folders to a minimum of 3? I have read the docs but it's nice to have a second opinion.
If I understand you correctly, you want to support as many screen sizes as possible with as little layouts as possible. Here is a good link to a PDF that should help you out.
Scaling Android Apps with White Paper
I want to create an app with pixel-perfect graphics for each resolution (I'm going to support only 3 or 4 of them). In my main activity I created new layout and selected 800x600 from available qualifiers. I edited it and then I created folder "layout-1280x720" for another resolution. I copied activity_main.xml from "layout-800x600" to "layout-1280x720" and edited new copy. But now when I run it in android emulator at 1280x720 I see layout from 800x600.
How can I create different layouts for each exact resolution?

You can see there a proper approach for your issue.
It's actually close to impossible to do that, because android doesn't have percent dimensions, of course you can use weight coefficients, but it won't be the solution. I will recommend you to use this app, which overlays your template over everything. It makes layout creating much easier and faster.
I am currently writing a remote control program to control a robot on all android devices.
I am trying to display the layout to fill the screen fully on different sizes. My first try was on a samsung 10.1' tablet and it was working well but when I port it to smaller devices like 4.3' the layout goes wrong. I am thinking of creating several layouts to match with different screen sizes but how do I check which layout to set according to screen sizes?
I have tried getwidth and getheight but it only works after you have set the layout.
Please give me a short sample code if possible as I am very new to this.
If there are any other better ways please advice me on it.
Please note that I am using API level 8, android 2.2.
Go through this and this. Basically, you create layout for various screen, each with same name. They are put in different folders (each named according to factors like- landscape, portrait, screen density and screen size). OS will decide on it's own about which layout to use.
This is great article about that. But in overall, never expect the screen to be any static size. But if you're deciding to create layout for each size, you don't have to worry about choosing the best layout, android will do it for you if you provide multiple versions of same layout.
You do not have to check the screen dimensions. Just create your layouts, and Android will automatically pick the correct one for your screen size, orientation, API level, etc. See here for more details: http://developer.android.com/guide/practices/screens_support.html
