android - Start Action Mode from custom CursorAdapter within ListFragment -

i trying start action mode contextual action bar, i'm having issues. using custom cursoradapter class extends listfragment contained class extends actionbaractivity.

structure
gamelistactivity (actionbaractivity)
---- gamelistfragment (listfragment)
---- ---- custom_adapter (cursoradapter)

i'm trying start action mode in onclick listener within custom_adapter. currently, have actionmode.callback in actionbaractivity:

public static final actionmode.callback anactionmode = new actionmode.callback() {     // standard funcs (oncreateactionmode, etc) } 

i feel though better suited in listfragment, i've tried no better luck.

in custom cursoradapter, have function:

private void set_action_mode() {     if (checked_count > 0)         if (!is_action_mode_showing)             ((gamelistactivity) m_context).startactionmode(gamelistactivity.anactionmode); } 

the error getting is:

error:(142, 47) error: method startactionmode in class activity cannot applied given types; required: android.view.actionmode.callback found: android.support.v7.view.actionmode.callback reason: actual argument android.support.v7.view.actionmode.callback cannot converted android.view.actionmode.callback method invocation conversion 

both classes import (what think) proper class:

import android.support.v7.view.actionmode; 

i original following this link, implementation doesn't appear work me either.

is there anyway i'm doing?

i think should use

startsupportactionmode

instead of

startactionmode

hope helpful!

ps: take of sintaxis. java convention says name of variables, objects or methods must start lowercase , no underscores allowed. seems you're using style of c naming. can find more info @ oracle tutorials , here.
