How to add more options to Android default Contextual Action Bar

Question

As we know, by default, after selecting some text on views, android displays Contextual Action Bar (CAB) with some default options, such as: copy, cut, select all...

Now, I want to have an application (that has only 2 options: ON/OFF), If I turn it ON, Some other options will be added to default CAB. If I turn it OFF, my custom options will be removed from Android default CAB.

My question is: Is it possible to Add/Remove some options to this default CAB? How can I make above application?

Thank you!

You'll have to use the setCustomSelectionActionModeCallback on each of your TextViews.

You can have a boolean:

boolean on = true;

Then create a method that actually edits the CAB like so:

private void editContextualActionBar(ActionMode actionMode, Menu menu) {
    if (on) {
        // adds a new menu item to the CAB
        // add(int groupId, int itemId, int order, int titleRes)
        menu.add(0, R.id.action_to_be_performed, 1, R.string.action_name);
    } else {
        // removes the new menu item
        menu.removeItem(R.id.action_to_be_performed);
    }
}

Finally, call the Callback on your TextView with the editContextualActionBar method in onCreateActionMode and perform the menu action in onActionItemClicked:

textView.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            editContextualActionBar(mode, menu);
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {

            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            switch (item.getItemId()) {
                case R.id.action_to_be_performed:
                    // perform action
                    return true;
                default:
                    break;
            }
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {

        }
    });
