Custom cut/copy action bar for EditText that shows text selection handles

I figured out the answer to my own question; TextView (and therefore EditText) has a method setCustomSelectionActionModeCallback() which should be used instead of startActionMode(). Using this enables customisation of the menu used by TextView for text selection. Sample code:

bodyView.setCustomSelectionActionModeCallback(new StyleCallback());

where StyleCallback customises the text selection menu by removing Select All and adding some styling actions:

class StyleCallback implements ActionMode.Callback {

    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
        Log.d(TAG, "onCreateActionMode");
        MenuInflater inflater = mode.getMenuInflater();
        inflater.inflate(R.menu.style, menu);
        menu.removeItem(android.R.id.selectAll);
        return true;
    }

    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
        return false;
    }

    public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
        Log.d(TAG, String.format("onActionItemClicked item=%s/%d", item.toString(), item.getItemId()));
        CharacterStyle cs;
        int start = bodyView.getSelectionStart();
        int end = bodyView.getSelectionEnd();
        SpannableStringBuilder ssb = new SpannableStringBuilder(bodyView.getText());

        switch(item.getItemId()) {

        case R.id.bold:
            cs = new StyleSpan(Typeface.BOLD);
            ssb.setSpan(cs, start, end, 1);
            bodyView.setText(ssb);
            return true;

        case R.id.italic:
            cs = new StyleSpan(Typeface.ITALIC);
            ssb.setSpan(cs, start, end, 1);
            bodyView.setText(ssb);
            return true;

        case R.id.underline:
            cs = new UnderlineSpan();
            ssb.setSpan(cs, start, end, 1);
            bodyView.setText(ssb);
            return true;
        }
        return false;
    }

    public void onDestroyActionMode(ActionMode mode) {
    }
}

The XML for the menu additions is:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/italic"
          android:showAsAction="always"
          android:icon="@drawable/italic"
          android:title="Italic"/>
    <item android:id="@+id/bold"
          android:showAsAction="always"
          android:icon="@drawable/bold"
          android:title="Bold"/>
    <item android:id="@+id/underline"
          android:showAsAction="always"
          android:icon="@drawable/underline"
          android:title="Underline"/>
</menu>
