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 .

Within one of my methods, I want to switch layouts into a secondary one. But for some reason, the setContentView can't see the layout in the folder. The following images show this:
My layout folder
I then ran the code
setContentView(R.layout.saveg_w_name) //I know this name is correctly spelled and everything since I clicked the createLayout
And yet it still gives the cannot resolve symbol error. Is this a bug with android studio or am I doing something wrong
Just restart your android studio and again check.
If it still doesn't solve your issue, try invalidating caches.
click File(Menu)->Invalidate Caches/Restart
I'm not sure if my question is worded correctly, but it's easier to show an image to explain my question.
In the XML editor, some values are replaced with the actual values that was defined for that entry. However, I don't want Android Studio showing me the actual values. Instead, I still prefer that it showed the reference names. So, how do you disable the editor from previewing in this manner?
In the image below, android:text="#string/sign_up", but the editor is showing it as android:text="Sign up...", as well as other attributes, and the reference name only shows up when I mouseover the attribute.
How to disable this feature permanently via Android Studio setting/configuration?
Update: Same thing is happening in .java files. Enums or R.string constants are being replaced by their actual values.
For Java files you can go to Preferences->Editor->General->Code Folding and uncheck "Android string references" but this only applies to code not to xml layouts

I fought with this for hours! Having the values show up instead of the references is great, in most cases, but I was working with a project imported from AIDE and its layouts were a mess. I need to see the references, not the values. I found the "possible duplicate" link above, mentioned by zombie, but it didn't work (or so I thought).
Finally, after reading this post, I tried unchecking the "Android string references" again, but this time I restarted Studio after (even though I wasn't prompted). If you have the same problem, the solution above should work, but save yourself (possibly) hours of aggravation and:
Restart Studio after unchecking the "Android string references" setting!
BTW, I would have added this as a simple comment, but SO wouldn't let me!
Is there any quick way to know if an image is referenced or used in a Java class or XML layout? For example like if an image.9.png is used in a certain layout. Thanks.
in Eclipse you cam make Search Like below Step .
First Click your Current Project in which you would like to Search .
Now Press Ctrl+H in windows that will open Search Dialog Window.
Now you want to check bg.png used in your Project ,Search like below in
#drawable/bg
This will search for all Layout and xml file which use this image.
Now for Search in java file you need to search with it's id which you give in xml file.
R.id.yourimageId
Now in your case you can search your #drawable/image by Ctrl+h Dialog in Eclipse.
EDIT In ADT updated version Like ADT 16 we have lint tool it will give all warning for unused Resource .
Issue: Looks for unused resources
you will find this warning in lint check .
for More about Lint Refer this Link Lint Checker SO
There's no way to do it via code. However, in Eclipse, if you delete the image (make sure you make a copy first) and build the project, you'll know the spots where you are missing it :)
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.
I'm fairly new to eclipse and android development, and I'm having what must be a pretty simple error to fix. I've done some development on my laptop and never encountered these errors. (I currently only have access to public computers, and have eclipse and the SDK installed on a USB drive.)
The first strange thing I noticed when editing the main layout was that there is no properties window to allow easy editing of various layouts and objects. (There was on my old computer) I have not been able to figure out how to get this window to appear.
So after adding one textView and modifying its properties by hand, I receive the following two errors when I attempt to run the program. (No code has even been added yet, just one textView)
http://i.stack.imgur.com/9VGT0.png (Link to screenshot of error, only have 6 rep)
All I've done is change the textView to have center gravity, fill_parent layout width, and a textSize of 22sp. I've tried googling the errors to figure out what I'm doing wrong but have been unsuccessful. Anybody encounter this before? Also, if anybody knows how to make the properties window appear it would be a great help.
Thanks in advance
When compiling Android stuff in Eclipse, you have to press the "Run" button with a .java file open, not with .xml file open. No idea why, but the glitch is there and you'll soon remember to avoid it.
To fix the current state, delete the 'main.out.xml' file (it was automatically created on compile). Then in the 'Problems' tab (the one on your screenshot), manually delete each problem it shows you. After that, press Run again with a .java file open and it should solve whatever is there now.
You get the properties window back from the "Show View" dialog, which is accessible from the "Window" -> "Show View" -> "Other ..." menu.
Once the dialog is open, look in the "General" folder for "Properties".
right click the .xml file and go to Open With... there are many ways to open it. I prefer the xml editor but there is also a layout editor available.
Your XML is not well-formed, e.g. mismatched elements, mismatched quotes, etc. Show your XML for more specific assistance.
