Contextual action bar with Adapter
I am trying to use contextual action bar for the first time and I have this design problem: In my main activity I have set an adapter to my list:
// Create an adapter
Adapter = new ToDoItemAdapter(this,
R.layout.list_date_item,
toDoListCursor,
from,
to,
toDoDBAdapter);
List.setAdapter(Adapter);
Now I need to setOnLongClickListener to each list item. where can I do that cause if I write it in my activity I don't have access to each 'view' like I have in the Adapter but if I write it in the Adapter class I don't have access to ActionMode.Callback or more important - to my logical methods such as - RemoveItem, ShareItem etc.
I would like to know what is the best practice to do this.
Solution
I have Done this in item click of ListView.
Note: i have used actionbarsherlock library.
check this code:

i have used OnClickListener same way you have to use OnLongClickListener
public OnLongClickListener longclick = new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
mMode = startActionMode(new AnActionModeOfEpicProportions());
Log.d("you are click on Ratings", "you are click on Ratings");
return true;
}
};
EDIT: without actionbarsherlock
using AppCompart Support Lib use
startSupportActionMode
without AppCompart
startSupportActionMode
