java - Share code between fragments -

i have 2 listfragments needs share code. basic creating abstract fragment extending listfragment , let 2 fragments both extend abstract fragment.

however, need third fragment use code abstract fragment. however, third fragment not listfragment gridfragment.

is there way solve problem?

as java won't support multiple inheritance either seperate generic code in fragment super class or make static methods.

or

simply write fragmentutil class.
