How can I remove formatting from text that is pasted into a SearchView?

I discovered that pasting a selection of SpannableString into a SearchView preserves the string's spans. What's the best way to strip away all of that formatting when the string is pasted into the SearchView?

Here's an example of what's happening:

pasted spanned string into searchview

The text above was colored grey, italicized, and superscript'd prior to being pasted.

I'm not sure if there is way to detect if the text is pasted or hand-input directly in the SearchView query listeners, but you can bypass it like:

  1. Obtain the TextView from the search_plate layout of the SearchView
  2. Keep that reference (as public, perhaps)
  3. Add the OnQueryTextListener
  4. Remove any span from the string
  5. Use the TextView reference to re-set the text that has no span.

Please try it and let me know.

 int searchTextViewId = mSearchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
            mSearchTextView = (TextView) mSearchView.findViewById(searchTextViewId);
        mSearchView.setOnQueryTextListener(new OnQueryTextListener(){

            @Override
            public boolean onQueryTextChange(String arg0) {
                if(!TextUtils.isEmpty(arg0)){
                    arg0 = removeSpan(new SpannableString(arg0));
                    mSearchView.setOnQueryTextListener(null);
                    mSearchTextView.setText(arg0);
                    mSearchView.setOnQueryTextListener(this);
                }
                return false;
            }

            @Override
            public boolean onQueryTextSubmit(String query) {
                // TODO Auto-generated method stub
                return false;
            }});
        }


    private String removeSpan(Spannable s){
          s.setSpan(new StyleSpan(android.graphics.Typeface.NORMAL),    0, s.length(),    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
          return s.toString();
    }

Also here is how to obtain last copied text from the Clipboard:

private boolean isTextPasted(Context context, String text){
        ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE); 
        if(!clipboard.hasPrimaryClip()) 
            return false;

        ClipData clipData = clipboard.getPrimaryClip();
        String lastClipText = clipData.getItemAt(clipData.getItemCount()-1).coerceToText(context).toString();
        return !TextUtils.isEmpty(lastClipText) && lastClipText.equals(text);
    }

Which you might add to the condition in OnQueryTextListener.
