How do I take into account form widgets eg Editbox, checkbox being different sizes in different android themes when designing my forms?
I am using proper relative layouts, but when I have several widgets in the table layout for example, and change the theme, some drop off the bottom!
Thanks
Well, for the "dropping off the bottom", all you need to do is add a ScrollView.
If you don't know how to use it, you can look it up here.
If your aim is to change the sizes of your widgets based on the phone, all that you will need to do is give a different layout file for your activity for each ldpi,mdpi,hdpi,xhdpi. with those specifications.
Look up "Providing different layout for different screen sizes" here

I want the same application to be delivered 2 different set of layouts. Ie the functionality is same but the graphics will be different for two different versions of the app. So i want to keep the same code and based of some variables want to decide which layout to be set for each activity. SO for each activity i will define two different layout.
This is my requirement. What is the best way to implement this. I can have an if else in each activity and define which layout to be set. Is that the right and best way. Please give your options on this
Take a look at this answer. It's about accessing a resource file from identifier, ie file name. You can do this with any type of resource (I think).
How to use getResource.getIdentifier() to get Layout?
Basically, you can do an if-else statement and assign the id of the layout you wish to use to a variable then load the layout using the identifier.
Actually there are many ways for ex you can change your layout based upon the orientation i.e landscape or portrait or you can change your layouts using languages for ex- you can create various folders for different languages.
Please explain your requirement briefly and if possible post some code also.
You can follow below links also.

Language Specific layout for android
http://www.c-sharpcorner.com/UploadFile/0e8478/supporting-different-languages-layouts-in-an-android-appli/
In this article http://developer.android.com/guide/practices/tablets-and-handsets.html
we use res/layout/main.xml with one fragment for handsets and res/layout-large/main.xml with two fragments for tablets. We must check if second fragment is in the layout to define if app runs on tablet or on phone.
I have 4 layout (2 for phone and 2 for tablet):
layout-port
layout-land
layout-sw600dp-port
layout-sw600dp-land
I check screen orientation to define if display is in portrait or landscape mode and check if layout contains a fragment to define if it is tablet or phone.
Is there any better way to work with layouts and fragments?
Is it possible to use one layout if we have two fragments for example http://i.stack.imgur.com/FtzKs.png and if a phone display doesn't fit both of them to show only the first one?
Thanks in advance! :)
What you're showing there is indeed possible! That is something called a Master Detail Flow (if you're developing in Eclipse with adt, check out he new activity wizard, which provides this as a template option).
This layout is basically just two fragments inside an activity (or, now, as of android 4.2, they can be nested in another fragment as well!) that interact with each other in a certain way. To create the layouts you linked to, one would detect whether the device is a phone or a tablet, and then set the visibility of the two fragments in different situations accordingly.
You will find a number of methods for detecting screen size here, whether you want to use screen size in inches, pixels, or the manufacturers' default categories.
And properties like visibility and sizing can be set programmatically using Layout Params and its various subclasses.
In any particular case, whether you choose to use multiple layouts to support different screen sizes or to do more of it programmatically is up to you. Personally, I think that it is always a good practice to design your code modularly and then use layouts to put all the pieces together (it'll save you a lot of headaches down the line if you decide you want to change things up). But either way, supporting more devices will always require more code, and there are no two ways around that...one of the curses of android development :P
When I place things like text boxes they are fixed in one position and I can't move them around easily.
How can I edit the style and maybe put an image at the top of the text boxes and give the app a neat and pretty little layout?
Thanks
Use RelativeLayouts instead of LinearLayouts (i assume that you are using them) which allow free positioning.
To modify the theme/colors, read Applying Styles and Themes.
Create 9-patch graphics and assign them as backgrounds.
I am unsure if this is what you are looking for,but you can arrange the object on the layout from the xml files in res/layouts/ folder.Do not forget to follow the UI guidelines provided by google for android development. Also you can create custom themes for you app if you do not like the default template.
From this this link i knew that if i want to create android resolution for all the device then i've to use Supporting Multiple Screens but how i can setcontentview for that?
You give equivalent layouts the same file name within each resolution folder. Hence they have the same ID. You pass that ID to setContentView(int layoutResID) and the Android system picks the right one for the device.
You don't have to use multiple layouts though. If you design your layout carefully, so that the views stretch or scroll in a sensible way, you may be able to use just the one.
we are confused with designing interface file for android,we have made user interface with Absolute layout and used "dip" instead of "px" (for different screen size issue) ,but it looks like,Absolute layout has been depreciated,and developer.android, recommends not to use Absolute layout
So other option we have is to use
1.Linear layout
2.Frame layout
3.Table Layout
But we are unable to bring Combination of above layouts so,that we can make button/widgets to proper position we need
How do we make widgets to desired position of screen with above said layouts and making them compatible with different screen sizes we have in android devices
would like to get a generic answer about same,
Tools used are: DrawDroid
The best layout to use if you were considering an AbsoluteLayout is a RelativeLayout.
Check out the Android Common Layout Objects page and its explanation of how to use a RelativeLayout.
Without more information on what you are trying to do, expanding this answer anymore is useless.
