android - Compilation error creating an adapter in a fragment -

i have fragment contains several views including listview. in order set adpater listview, thought i'd recycle old (working) code i'd written in activity. code in activity looked this:

adapter = new myadapter(             this,             list_of_things,             r.layout.custom_row_view,             new string[] {"label","day","time"},             new int[] {r.id.text1,r.id.text3, r.id.text2}             ); 

where myadapter method within activity's class, defined so...

public class myadapter extends simpleadapter {  

now tried put same myadapter method inside fragment class , called

adapter = new myadapter(             this,             list_of_things,             r.layout.custom_row_view,             new string[] {"label","day","time"},             new int[] {r.id.text1,r.id.text3, r.id.text2}             ); 

but compile time error:

the constructor mytestfragment.myadapter(mytestfragment, arraylist<hashmap<string,string>>, int, string[], int[]) undefined 

i don't know whether bug minor typo - or whether more fundamental, not being allowed adapters within fragments.

use getactivity() instead of in myadapter

adapter = new myadapter(             getactivity(),             list_of_things,             r.layout.custom_row_view,             new string[] {"label","day","time"},             new int[] {r.id.text1,r.id.text3, r.id.text2}             ); 

because this in myadapter referencing fragment , not activity.
