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.


Solution

  • 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.
