public void afterTextChanged(Editable s) {
    edittext.removeTextChangedListener(this);

    String newstr=oldstr.replaceAll("\\s+","@");

Have a look here.

You should be able to replace all the spaces with something like ' @'.

Just call

string = string.replace(" ", " @"); 

in your listener.

Of course, you should also take care of the first word, which (typically) should not have any space before. You could use a placeholder to do so, like

<string name="converted_string">@%1$s</string>

then in java

your_textView.setText(getString(R.string.converted_string, yourNewReplaceString));
