从适配器我从行中定义的按钮获取onClick事件.在onClick方法中我得到一些id,我想传递给ListFragment做一些事情.

如何从适配器调用ListFragment中的方法showTask？

listfragment

public class TaskListFragment extends ListFragment{

    /* ... */

    @Override
    public void onCreate(Bundle savedInstanceState) {       
        super.onCreate(savedInstanceState);
        mAdapter = new TaskListAdapter(getActivity(),data);        
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) 
    {
        super.onActivityCreated(savedInstanceState);
        setListAdapter(mAdapter);
    }   

    public void showTask(long id) {

        FragmentTransaction ft = getFragmentManager().beginTransaction();

        TaskFragment taskFragment = new TaskFragment();

        Bundle args = new Bundle();
        args.putLong("id",id);
        taskFragment.setArguments(args);

        ft.replace(R.id.fragment_container,taskFragment);
        ft.commit();         
    }
}

适配器

public class TaskListAdapter extends ArrayAdapter<Task>{

    /* ... */

    private OnClickListener mOnClickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            long id = (Integer) v.getTag();
            // how can I call showTask(id) ?
        }
    };
}
