Is it possible to convert R.java into layout file xxx.xml..
In some project which I got from internet the layout file is missing and all I have now is R.java.
So is there any way that I can create/extract information from R.java file to make the layout xml file.
That is not possible. the R class only handles references to content (like layouts), not the content itself.
R.Java is the pretty much the only file that you don't need. This file is automatically generated when your project is compiled.
Because of this, you should not edit this file in any way.
Therefore, if all you have is the R.java file... Well, you have nothing.
you can't do that, if R.java deleted your only way is add the xml again. i think create layout programmatically in android better than with xml. because the R doesn't need to generate. but the weakness of programmatical layout is you must declare id by your self. generate or manual which one do you like :)

I'm trying to programmatically set the ID of a TextView simply using the line
titleView.setId(R.id.installedTitle);
but I get an error at this line that states:
"installedTitle cannot be resolved or is not a field"
What could be wrong here?
You have (maybe) not cleaned your Project, so it may be possible that your R File has not been generated. You may also have some errors in your Project (xml files) so the R wont get generated aswell. You may also not have used setContentView() before and loaded the Layout and/or the ID is not in your layout.
I have a couple of xml files in my layout folder but when I use them in my class the template proposals doesn't show my layout files but shows android default proposals. There seem to be no error in any of my files at all. I tried deleting the R.java file and rebuilding and restarting eclipse but nothing seems to be working. PLease help. I need to get this done asap :(
Thanks,

This may be because, when you try to use your xml layouts, the default android R file is imported.
import com.android.R
Check that. If it is there, delete that import and import the correct R file which starts with your package name.
First look are you setting xml name fine like
e.g
you have your.xml
Then in onCreate
super.onCreate(savedInstanceState);
setContentView(R.layout.your);
Then clean your project.
if you have design multiple xml with same name then you must have to place them in appropriate folder using hdpi etc
Further details available here
or you can write
import.R.layout
It will work for sure
I tried to organized my layout.xml files, and made a directory
/res/layout/content/
Then I tried to point to a file there from the code like this:
setContentView(R.layout.content.product_strategy);
but I get an error that the content is not a field that can be resolved.
What am doing wrong?
Thanks!
You can't make your own resource folder in android.
Please take a look at this link provding information about resource folders:
http://developer.android.com/guide/topics/resources/providing-resources.html
R.java doesn't create references to subdirectories in resources. That's the reason. So you need to use the single level default directory structure.
Is there a way to easily rename XML files in Eclipse while developing for Android so that these changes are reflected in source code?
Right-clicking on the file in package view and selecting refactor->rename changes the file's name, but does not alter references to the file within the .java source files.
I realise this is an old post, but i was trying to do the same and just came up with a solution to this in eclipse:
Search -> File Search -> Replace...
Replace:Current.Style.Name
With: New.Style.Name
Thats it! Nice and easy, i didn't want to deal with the hassle of going into all my xml layouts and changing them.
I do not think such a thing exists for Android resources directory let alone layouts. You have to change the references manually.
I am beginner in android so some beginer problems is occured. I create second activiy and second layout xml file named getNearest.xml. The code section to show this file is
setContentView(R.layout.getNearest)
But eclipse cannot be find getNearest. It only shows .main. So what is the problem with this?
You need to build at least once to have the R.layout values updated when you create a new layout. Also make sure you saved the layout file and that it exists under the res\layout folder.
