Android - GUI not found

I'm working on my first Android App using the Android SDK for Eclipse and the eclipse plugin (ADT) Recently I've encountered an error while trying to build an UI in XML with the GUI. Any time I try to open a layout XML file, I can't find the graphical interface (No Layout TAB, just the source and the design tabs).

I have to write all the XML code. I think that graphical editor is broken and I don't know what I have to do. Anyone else have the same problem or any suggestions?

did you try to re install the ADT Plugin ?? if it doesn't work , you can use this website , it is very useful , and then just copy/paste your code :

May be you have already try it, but try to remove then reinstall eclipse android plugin. For me it worked when I had a similar issue. If not work, witch version of Eclipse do you have (Not only the number version, but also give if you dowload eclipse for java developer, ...) and witch Android SDK do you use ? JHelp
