If you are getting red line below setOnItemClickListener and OnItemClickListener that means you are not importing proper classes so try to first import all required classes (in eclipse that is ctrl+shift+o in eclipse(windows)).

But one thing that you are telling is that you also getting red line below HelloGridView ,however this should not happen(because this is class name and HelloGridView .this will be context(this is very basic but as you said you are new I am telling you)) kindly check your class whether it is extending to Activity or not like this

HelloGridView extends Activity

If you have done this thing also, kindly check for required jar files that your application needs, you can check this by right click your project Java Build Path ->Order and export
select your api(contains jar file,if not selected) press select all button and press OK and you are done then.

If still you do not get classes that you required you clean your project that is Project -> clean
