Q:

Not getting content assistant/ intellisense in Eclipse

I having issue that content assistant / intellisense is working in methods such as onCreate but when I am calling it inside onClick method its not working.
I have attached screen shots of both scenarios.

Above image show its working when I call it using ctrl + space in oncreate method

Above image its not working
Also I am getting this error "The method onCreate(Bundle) of type ACTIVITY NAME must override or implement a supertype method"
shown in image 

But activity is already overriding super method.
This is only happening in  this activity, other activities content assistant is working.

A:

Have you tried to Reset To Default Option in : 
Windows -> Preferences -> Java -> Editor -> Content Assist -> Advanced
In that "Api Proposal tools" is Main.
Then it will work, in that above window all options are for intellisense ( Ctrl + Space) only,  just have a look, if gets confusing then just set it to Default and ya that's it.
