How to disable copy paste from to EditText

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 onLongClickListener on each EditText so that the context menu showing copy paste inputmethod  and other options does not show up  So the user won t be able to copy  paste into the Edit fields    OnLongClickListener mOnLongClickListener   new OnLongClickListener               Override         public boolean onLongClick View v                   prevent context menu from being popped up  so that user                cannot copy paste from into any EditText fields              return true                     But the problem arises if the user has enabled a third-party keyboard other than the Android default  which may have a button to copy paste or which may show the same context menu  So how do i disable copy paste in that scenario    Please let me know if there are other ways to copy paste as well   and possibly how to disable them   Any help would be appreciated

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:

Text selection handle with paste menu

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.

Read the Clipboard  check against the input and the time the input is  typed   If the Clipboard has the same text and it is too fast  delete the pasted input

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

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  gt   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

You can do this by disabling the long press of the EditText  To implement it  just add the following line in the xml -  android longClickable  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
