Question

In my application, there is a registration screen, where i do not want the user to be able to copy/paste text into the EditText field. I have set an onLon

Answer 1

I am able to disable copy-and-paste functionality with the following:

textField.setCustomSelectionActionModeCallback(new ActionMode.Callback() {

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

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

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

    public void onDestroyActionMode(ActionMode actionMode) {
    }
});

textField.setLongClickable(false);
textField.setTextIsSelectable(false);

Hope it works for you ;-)

@Zain Ali, your answer works on API 11. I just wanted to suggest a way to do in on API 10 as well. Since I had to maintain my project API on that version, I was constantly playing with the functions available in 2.3.3 and got a possibility to do it. I have share the snippet below. I tested the code and it was working for me. I did this snippet on an urgency. Feel free to improve the code if there are any changes that can be done..

// A custom TouchListener is being implemented which will clear out the focus 
// and gain the focus for the EditText, in few milliseconds so the selection 
// will be cleared and hence the copy paste option wil not pop up.
// the respective EditText should be set with this listener 
// tmpEditText.setOnTouchListener(new MyTouchListener(tmpEditText, tmpImm));

public class MyTouchListener implements View.OnTouchListener {

    long click = 0;
    EditText mEtView;
    InputMethodManager imm;

    public MyTouchListener(EditText etView, InputMethodManager im) {
        mEtView = etView;
        imm = im;
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            long curr = System.currentTimeMillis();
            if (click !=0 && ( curr - click) < 30) {

                mEtView.setSelected(false);
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mEtView.setSelected(true);
                        mEtView.requestFocusFromTouch();
                        imm.showSoftInput(mEtView, InputMethodManager.RESULT_SHOWN);
                    }
                },25);

            return true;
            }
            else {
                if (click == 0)
                    click = curr;
                else
                    click = 0;
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mEtView.requestFocusFromTouch();
                        mEtView.requestFocusFromTouch();
                        imm.showSoftInput(mEtView, InputMethodManager.RESULT_SHOWN);
                    }
                },25);
            return true;
            }

        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            mEtView.setSelected(false);
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    mEtView.setSelected(true);
                    mEtView.requestFocusFromTouch();
                    mEtView.requestFocusFromTouch();
                    imm.showSoftInput(mEtView, InputMethodManager.RESULT_SHOWN);
                }
            },25);
            return true;
        }
        return false;
    }

If you don't wan't to disable long click because you need to perform some functionality on long click than returning true is a better option to do so.

Your edittext long click will be like this.

edittext.setOnLongClickListener(new View.OnLongClickListener() {
      @Override
      public boolean onLongClick(View v) {
            //  Do Something or Don't
            return true;
      }
});

As per documentation Returning "True" will indicate that long click have been handled so no need to perform default operations.

I tested this on API level 16, 22 and 25. Its working fine for me. Hope this will help.

Here is a hack to disable "paste" popup. You have to override EditText method:

@Override
public int getSelectionStart() {
    for (StackTraceElement element : Thread.currentThread().getStackTrace()) {
        if (element.getMethodName().equals("canPaste")) {
            return -1;
        }
    }
    return super.getSelectionStart();
}

Similar can be done for the other actions.

If you want to disable ActionMode for copy/pasting, you need to override 2 callbacks. This works for both TextView and EditText (or TextInputEditText)

import android.view.ActionMode

fun TextView.disableCopyPaste() {
  isLongClickable = false
  setTextIsSelectable(false)
  customSelectionActionModeCallback = object : ActionMode.Callback {
    override fun onCreateActionMode(mode: ActionMode?, menu: Menu) = false
    override fun onPrepareActionMode(mode: ActionMode?, menu: Menu) = false
    override fun onActionItemClicked(mode: ActionMode?, item: MenuItem) = false
    override fun onDestroyActionMode(mode: ActionMode?) {}
  }
  //disable action mode when edittext gain focus at first
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    customInsertionActionModeCallback = object : ActionMode.Callback {
      override fun onCreateActionMode(mode: ActionMode?, menu: Menu) = false
      override fun onPrepareActionMode(mode: ActionMode?, menu: Menu) = false
      override fun onActionItemClicked(mode: ActionMode?, item: MenuItem) = false
      override fun onDestroyActionMode(mode: ActionMode?) {}
    }
  }
}

This extension is based off above @Alexandr solution and worked fine for me.

Best method is to use:

etUsername.setLongClickable(false);
