Eclipse luna and automatic support

I have installed Eclipse Luna but there is a problem because it not give me any help for automatic complete function. In android, with eclipse standard, if I extend a class if you want can automatically insert all methods that the class can use. For example if I write
class pView extends Ui.WatchFace{
..
..
..
}


If I click with right mouse button I should be able to automatically insert the method :
- Initialize
- onEnterSleep
- onExitSleep

Why Luna not give me this possibility ?
