I don't get this. I've searched everywhere and no one's answers have solved this for me.
Why does this keep happening? I can't do anything! The XML Code is still there, but it doesn't show anything in the Graphical Editor. The Palette comes up if I change it to "4in WVGA (Nexus S)" or some other configuration, but I still can't see anything and the Theme drop down menu is unselectable. All my XML documents are like that.
Just delete any custom device screen configuration you have added . It will solve the issue :)
That just happen to me and after some attempts I found the reason.
When I first opened the project in eclipse I found some errors related with the version of Java. I changed the JDK compliance to 1.6 (Project->Properties->Java Compiler) and all errors dissapear but all graphical layouts went blank.
I uncheked "Enable project specific settings" (Project->Properties->Java Compiler) and now all the graphical layouts are working.
When everything fails, close eclipse and start it all over again, it solved my problem.
I also had that problem, it happened to me when i imported my project. after some time I came to reason just change the workspace of eclipse to folder, which contains your folder.
I changed workspace on opening eclipse, there can be some other way as well
hope this will solve it
If it has never worked for you (or something went wrong upgrading your SDK, as in my case), you may need to install an extra package. For me the issue was fixed when I installed Android Native Development Tools under NDK Plugins (SDK version 20).
I had this problem since I switched the option Show previews in the palette. I switched to show only icons, everything is ok now.

I had several layouts for various size devices and at each orientation. Somehow, they've all disappeared and only the original layout shows again, no matter which device type or size or orientation I select in Android Studio's renderer.
I've upgraded Android Studio. I've renamed the parent folder the source project and files were in. I've upgraded the sdk. Also, Although my app is not a Gradle project, I did something the IDE kept bugging me to do... I believe I moved something from AndroidManifest to build.gradle.
I don't know which step caused me to lose my layouts, as I didn't notice as I worked on other things.
Does anyone have any idea what I might have done that would cause my layouts to disappear?
Thanks.
They have not disappeared and you have not lost them!
Click on the drop down which I have circled (It probably says Android for you) and choose "Project" view which is what you were used to before the update.
since I updated my Android SDK today I get some strange Lint errors in my project. The activity contains amongst others a textview. Everything works fine, but if I want to change the text size of the view within the code with .setTextSize(float size), I get in other lines (and also other independent methods) errors that a call requires a certain API level. But that are calls like string.isEmpty(), which is available since API level 1.
What am I missing? And I know, I can set the text size also in the xml-file, but I want to change it during runtime.
Any ideas?
Thanks!
Best regards

I think I got into something similar some time ago (nonsense Lint errors)...
Are you working with Eclipse?
If so, you can try the following:
Restart Eclipse
Clean your project (Project->clean...)
Click the button "Runs Android Lint..." (it's in the toolbar, between the "Virtual device manager" and the "new project wizard")
I don't remember exactly what did I do to solve the problem, I hope it works though
Good luck!
With the latest release, I've had a few times where the lint errors were just incorrect. (missing semicolon on a line with a semicolon, etc).
In such cases, you can right-click on lint error warning, or on the numberings on the left side, and select "Clear All Lint Markers".
This will allow you to compile the file once, and if that works, Lint seems to start acting normally again.
This is the error I'm getting in my layout XML files:
error!
NotFoundException: null
Exception details are logged in Window > Show View > Error Log
The following classes could not be found:
- TextView (Change to android.widget.TextView, Fix Build Path, Edit XML)
This happened after updating my SDK tools in Eclipse. However, I can still compile my code, I just can't see the graphical part of my layout.
Recently, I also added the RootTools library, could that also be the cause?
Thank you!
I had the same problem. And it turned out to be a very strange thing.
In my strings.xml file I had a line
<string name="email_seperator_char">\#</string>
And this was causing the problem. Even if I use the escape character for # sign preview was not working after SDK update.
SOLUTION:
I just added a space in front of it and voila, it worked.
<string name="email_seperator_char"> \#</string>
I know it is strange and it may not be acceptable for some apps to have an space infront of it. But that was ok for my app. Hope this helps.
And in design mode, in graphical layout, you have a new icon, (android icon), click and select 8 minimum.
I'm not sure it helps in your case, but I found out what was the problem with mine. To support older Android devices, I lowered my project build target to API level 7 (Android 2.1) from the previous value of API Level 8 (Android 2.2).
There might be an issue with the 2.1 layout renderer, it kept crashing on my TextView's property android:textAppearance="?android:attr/textAppearanceMedium". Even when I removed it, rendering was working but had a strange appearance (grey background, tiny black text). Switching the API level back fixed the layout editor straight away.
To change it, go to your project properties, select Android on the right, then tick the box next to your desired API level under Project Build Target.
I ve got the same issue just a minutes ago, try to lower the API level, press the andorid green icon in the layout editor screen and on the dropdown menu select API 7. I think it would be work out.
I've been having similar issues. After reading a number of these posts, I've found that there is probably a bug in the layout renderer for Android 4.0.3. An error message is listed (ROOT
Exception details are logged in Window > Show View > Error Log) even when all parts of the project are set to Android 4.0.3 and SDK 15.
If I set the layout renderer to Android 2.2 and leave everything else set to Android 4.0.3, SDK 15, then it all appears to work just fine.
I hope this is useful.
there is something wrong in your TextView
one time I wrote this which cause the problem
android:textAppearance="#android:attr/textAppearanceLarge"
the Eclipse can`t tell that is wrong but the design view crashes,when I realized that,I change # to ?
android:textAppearance="?android:attr/textAppearanceLarge"
then all comes to normal
My situation is: I once made an android project(2.2 version) but soon needed to format my computer. After formatting, I downloaded eclipse again but when I imported my project, I wasn't able to use the 'graphical layout' menu for xml. It doesn't show me anything like the picture below.

I cleaned the project and updated the Android SDK, however, none of these seemed to work well. What could be causing this?
Try restarting Eclipse. Usually that solves the problem for me when that happens.
Right click on your layout xml file and select Open With -> Android Layout Editor. It will force eclipse to open file in android's layout editor mode
None of above worked for me. what worked for me is:
1- Select a Google APIs Project Build Target rather than one of the Android X.X ones. This setting is in right click on project -> Properties->Android.
2- Make a change in XML and save it. Now switch back to "Graphical Layout" and it will show the layout.
For some, only 2nd step works.
This Question was asked 3 year ago, I am sure that you have get your solution, however i was also facing the same problem but got the solution in eclipse, here it is:-
1)Goto help->AboutEclipse->Installation details.
2)check the version of Android DDMS, Android development tool, Android hierarchy viewer, Android native development tool, Android trace view and tracer for openGl ES in installed software tab.
3)If they have different version than you have to update all of them.
4)Goto help->check for update in eclipse and follow the instruction.
5)Then restart eclipse.
This solve my problem.
The topic seems a little bit cold, but I wanted to add it nonetheless.
I had a similar problem with my layouts recently. When i create a project it automatically creates the layouts in the latest version of Android (eclipse shows it as version 22 of android as of today). But i can't see anything. So i just change the version to, say 18, and it shows ok. Furthermore if i want to change it back to version 22 it throws and exception, saying that a class can't be instantiated. (I am probably missing a class or a library on my system.)
Therefore if you cant see the layout it might be a good idea to switch back to earlier versions for development. cheers.
After upgrading the Android SDK through the AVD manager, I cannot preview XML layouts any longer in eclipse for Android 2.2 previews. Eclipse says, "LayoutLib is too recent. Update your tool!"
Using the drop-down and choosing any other platform works fine. Why is this happening for Android 2.2 previews?
I have also updated the ADT plugin for ecplise as well. Any suggestions?
This is a bug: http://code.google.com/p/android/issues/detail?id=17369
Updating from 10.0.1 to 12.0.0 resolved this issue for me.
In Eclipse, Help --> Check for updates
You'll likely see three items to be updated to 12.0.0+. Install, restart Eclipse, and the layout view should display without error.
More of a fix than an answer, or a fix with no explanation: r-click on the res\layout*.xml file you want to open, select Open with, then select Android Layout Editor. That should open the .xml in the graphical layout/design view you're used to.
For whatever reason, after updating from 10.0.1 to 12.0.0, my layout viewer default changed to XML Editor (one of the options under the context menu referenced above), and I have to manually open with different editor. Opening manually selecting Android Layout Editor seems to set ALE as the default for that .xml file going forward.
I had the same issue. Went in Eclipse->Help->CheckforUpdates. Selected everything there and hit next. Keep hitting next until finish. The update will start at the bottom right hand corner. Will also ask for permission. Press "OK". Will restart eclipse and problem is solved. I guess there was a bug with ADT but whatever this update fixed it.
