How to Disable Copy/Paste From/To Edittext

How to disable copy/paste from/to EditText

If you are using API level 11 or above then you can stop copy,paste,cut and custom context menus from appearing by.

edittext.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;
            }
        });

Returning false from onCreateActionMode(ActionMode, Menu) will prevent the action mode from being started(Select All, Cut, Copy and Paste actions).

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

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.

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

EditText: Disable Paste/Replace menu pop-up on Text Selection Handler click event

Solution: Override isSuggestionsEnabled and canPaste in EditText.

For the quick solution, copy the class below - this class overrides the EditText class, and blocks all events accordingly.

For the gritty details, keep reading.

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.

So incorporating these updates into a class that also has the setCustomSelectionActionModeCallback, and the disabled long-click, here is the full class to prevent all editing (but still display the text selection handler) for controlling the cursor:

package com.cjbs.widgets;

import android.content.Context;
import android.util.AttributeSet;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;


/**
 *  This is a thin veneer over EditText, with copy/paste/spell-check removed.
 */
public class NoMenuEditText extends EditText
{
    private final Context context;

    /** This is a replacement method for the base TextView class' method of the same name. This 
     * method is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup
     * appears when triggered from the text insertion handle. Returning false forces this window
     * to never appear.
     * @return false
     */
    boolean canPaste()
    {
       return false;
    }

    /** This is a replacement method for the base TextView class' method of the same name. This method
     * is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup
     * appears when triggered from the text insertion handle. Returning false forces this window
     * to never appear.
     * @return false
     */
    @Override
    public boolean isSuggestionsEnabled()
    {
        return false;
    }

    public NoMenuEditText(Context context)
    {
        super(context);
        this.context = context;
        init();
    }

    public NoMenuEditText(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        this.context = context;
        init();
    }

    public NoMenuEditText(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        this.context = context;
        init();
    }

    private void init()
    {
        this.setCustomSelectionActionModeCallback(new ActionModeCallbackInterceptor());
        this.setLongClickable(false);
    }


    /**
     * Prevents the action bar (top horizontal bar with cut, copy, paste, etc.) from appearing
     * by intercepting the callback that would cause it to be created, and returning false.
     */
    private class ActionModeCallbackInterceptor implements ActionMode.Callback
    {
        private final String TAG = NoMenuEditText.class.getSimpleName();

        public boolean onCreateActionMode(ActionMode mode, Menu menu) { return false; }
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) { return false; }
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) { return false; }
        public void onDestroyActionMode(ActionMode mode) {}
    }
}

I've tested this in Android v4.4.2 and v4.4.3.
