Android: How to TOTALLY disable copy and paste function in Edittext

I am quite new to Android developing area and recently I hv encountered a tough problem.

I was trying to make a Edittext which should NOT ALLOW user to copy content from or paste content to it. I hv googled a lot and find there seems to be 2 popular ways of doing so:

1st way, to set it in the layout file:


2nd way, to programmatically set it:

myEdittext.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;

public void onDestroyActionMode(ActionMode mode) {


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

public boolean onActionItemClicked(ActionMode mode,
MenuItem item) {
return false;

But I just found that whichever way I chose, the edittext area could only be disabled from long clickable, which then prevents user from accessing the "select all, copy and paste" menu through long clicking. But both the 2 solution DID NOT prevent the user from accessing the "paste" function through just a simple tap on the cursor.

So my question is: how could I TOTALLY block user from copy and paste function in a certain Edittext. Is anyone help? Thx a lot


There is one possibility, by disabling the cursor handler. You won't get the paste button, but you will also not be able to move the cursor with touch.

public boolean onTouchEvent(MotionEvent event) {
    if (event.getActionMasked() == MotionEvent.ACTION_UP && mDisableCursorHandle) {
        // Hack to prevent keyboard and insertion handle from showing.
    return super.onTouchEvent(event);
