I am working on an app built upon an example from a tutorial. Now the different widget IDs no longer reflect their purpose so I would like to rename them. However, this seems quite a task as the IDs are used in multiple files.
Is it possible somehow to rename the IDs so the changes are migrated into the other files in the project? That is pretty much similar to refactor source code names, but for widget IDs.
I don't think a tool like that exists in Eclipse. The easiest way to do it manually is to rename an item in the XML layout and then track down the errors in the Java classes. If you do it one-by-one then you should have it cleaned up in a minute or two.
You can try to use the Find/Replace function is Eclipse. I have found this useful several times when changing ID's or something to that effect. Let us know what you end up doing.
In eclipse:
Go to the xml layout -> Graphical Layout -> Properties then click the ... button near the desired field:
In case anyone stumbles across this problem now, you can rename the ID from the visual layout editor and it will do all the hard work automatically.

This issue started happening when I copied a layout into another and tried to refactor the ID in the new file. It tends to refactor the ID in the source file also.
This is quite frustrating as the layout I've designed for a particular activity gets change everytime I try to update several IDs of its views.
I'm a super beginner in Android Studio and any kinda help/guidance would be really appreciated! Thanks!!
every time you refactor something, it will change everything related to that particular item or field, if you want to refactor an ID of an item it will change it in everywhere this ID is being used.
in order to change the name you can right click and choose refactor and rename or you can press SHIFT+F6 for a shortcut, it will ask you if you want t search it in comments and strings also check that box in order to really change it everywhere that this item is being used.
If you want to rename only the ID in the xml without it being changed in the java file, you'll have to change it by hand 1 by 1 b/c the refactor option will change it everywhere it is being used in your current project.
I have a lot of views in a lot of layout files with some common properties that I need to remove. For the sake of argument let's say I have one layout file with 10 views with one common property which is android:minWidth that I need to remove. Is there a more efficient way in the android studio or from the XML file to find and delete them altogether instead of removing them one by one.
If I try the good old ctrl+f to find all occurrences of android:minWidth and then try to delete all of them from XML it still wouldn't be efficient because then I'll have to delete the values assigned to the said property one by one because those values are uncommon so cannot be used in find.
I am suggesting you this is not best practice to implement all the parameters in layout.
There is one concept in android style for common attributes. We should use style for best practice.
I think you have to remove that parameter using ctrl+f and replace by space one by one.
Click on find and replace button in your android studio and file all android:minWidth and replace it with blank or with what you want to replace. Try this it will help you.
To my understanding, the content file is just the xml files contents...but in a separate file. Whats the point?
I've seen
What is the role of content_main.xml in android studio 1.4?
and there doesn't seem to be much documentation about content_XXX.xml, so I was wondering, why did the new update include the default creation of this file?
Why divide the code into two files, why not just put all of the contents in its own xml file, I've tried it...and it works. I fail to understand why the content_main file is generated on creation of a new project.
Can someone give me a list of benefits of why I should be using the content file?
Thanks,
Ruchir
activity_main.xml is used to display coordinatorLayout, tabLayout, floatingActionButton, viewPager etc.
content_main.xml is used to display your stuff i.e. what you want to display to users.
for more details check my answer here.
Update after conversation in comments below: The point of doing this is to bring in more organization in the code. We can always go forward with the old way of putting everything in one file. Android Studio is just giving us a start with keeping the layouts in a more organized way to allow easy comprehension of code and reuse wherever possible, by segregating related stuff.

I'm not sure why the 'totalPlus' id won't show up.
I've fixed the mismatch naming problem that the picture shows. Still no luck.
Have you tried cleaning the project or even restarting Eclipse itself?
Also, there may be some other problems/errors in your res folder that can affect the proper R.java auto-generation.
If those do not work, try to insert your textviews via the Graphical Layout and then rename them by right-clicking on them and select "Edit ID". This should do a proper re-factoring.
You can also take a look at the official Layout guide here .
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.
