I am facing problem with eclipse that is when I am using the Android xml layout file to design a screen, I try to add attribute to an element that I have already created. I used to type two letters of the attribute then tap ctrl+space so it will show list of all available attribute by IntelliSense. Now it is not showing anything, instead it is showing a message at the bottom of the screen like below image.
Anybody faced the problem and solved it?
Appreciate your help because it is slowing down my work.

Answer Updated:
Here it goes,
I guess you are trying to access
Parameter Hints (Ctrl+Shift+Space)Instead of DefaultContent Assist (Ctrl+Space).If we press
(Ctrl+Shift+Space)in the java file it will gives you the detailed parameter description with the particular list of method names.If we press
(Ctrl+Shift+Space)in the xml file , it will gives the following errors,(a.) Element or or anything is unknown.
(b.) Content assist not available at the current location.
(c.) No completions available.
Old Answer:
According to the Eclipse content assist documents ,
the
Element Unknownerrors are because of,The
Element, we are looking for is not definedin-scope schema definitions.XML Content Assistwill be loaded from theschemafiles and the belongingxmlfile descriptions.So mostly no chances to be missed
Elementsinandroid sdk.Check whether any thing missed out in the following
preferences,Window-preferences-XML-XML Files-Editor- Content Assist Check the
prioritiesor reset it.I guess, You may missed somewhere, because i noticed that in your attached image,
Graphical Layout.xmlis your layout name. It cannot be named like that,In
android, it should be without any space and should “Starts with lower case”.If you give the detailed *error report*, then it is possible for somebody to tackle it.
You mentioned that , for all of the
layoutfiles you are getting the same error,so you can create a simple sample layout and paste with your question.
So my suggestion is, please check whether do you went wrong in somewhere in the xml file by
defining and providing open with priorities or not.
And do check the
XML Content Assistin the Window-Preferences menu.
