In addition to the setCustomSelectionActionModeCallback, and disabled long-click solutions, it's necessary to prevent the PASTE/REPLACE menus from appearing when the text selection handle is clicked, as per the image below:

The solution lies in preventing PASTE/REPLACE menu from appearing in the show() method of the (non-documented) android.widget.Editor class. Before the menu appears, a check is done to if (!canPaste && !canSuggest) return;. The two methods that are used as the basis to set these variables are both in the EditText class:

• isSuggestionsEnabled() is public, and may thus be overridden.
• canPaste() is not, and thus must be hidden by introducing a function of the same name in the derived class.
