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

Question

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

Answer 1

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);
}

Answer 2

best programmatically way is:

myEdittext.setLongClickable(false);

Or, just in xml

android:longClickable="false"

Answer 3

You can totally hide "select all, copy and paste" menu and also "paste" function which pop up when simple tap on the cursor.

For that you have to create a custom EditText class. Here is an example...

// Custom EditText class
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) {}
    }
} 

Use this EditText in your layout. Now, it will not show any copy/paste menu. It will show only blue handle but when you click on that you will not get any pop up of paste option.

Hope this helps...

the solution is very simple

public class MainActivity extends AppCompatActivity {

EditText et_0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    et_0 = findViewById(R.id.et_0);

    et_0.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            //to keep the text selection capability available ( selection cursor)
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            //to prevent the menu from appearing
            menu.clear();
            return false;
        }

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

        @Override
        public void onDestroyActionMode(ActionMode mode) {

        }
    });
   }
}
