String s2 = String.valueOf((EditText) findViewById(R.id.editText));
editText2 = ((TextView) findViewById(R.id.editText2));
button1 = (Button) findViewById(R.id.button1);
rg1= (RadioGroup) findViewById(R.id.radioGroup2);
button1.setOnClickListener(this);
public void onClick(View v) {
int selectedId=rg1.getCheckedRadioButtonId();
rb1=(RadioButton)findViewById(selectedId);

void OnClick(View v){
StringTokenizer s1 = new StringTokenizer(s2,"");
while (s1.hasMoreTokens()) {
}
editText2.setText((CharSequence) s2);

This would be best moved to the developers forum.
That was what I was thinking, except that I wasn't certain that it was about development. Since the OP hasn't responded, it's down to the two of us, and I think we're both agreed about it. Over it goes. :)

I have used this before for autocompletetextView in my notepad application. Example below of space tokenizer :
public class SpaceTokenizer implements Tokenizer {

public int findTokenStart(CharSequence text, int cursor) {
int i = cursor;

while (i > 0 && text.charAt(i - 1) != ' ') {
i--;
}
while (i < cursor && text.charAt(i) == ' ') {
i++;
}

return i;
}

public int findTokenEnd(CharSequence text, int cursor) {
int i = cursor;
int len = text.length();

while (i < len) {
if (text.charAt(i) == ' ') {
return i;
} else {
i++;
}
}

return len;
}
You may find similar inspiration at Android development tutorial

public CharSequence terminateToken(CharSequence text) {
int i = text.length();

while (i > 0 && text.charAt(i - 1) == ' ') {
i--;
}

if (i > 0 && text.charAt(i - 1) == ' ') {
return text;
} else {
if (text instanceof Spanned) {
SpannableString sp = new SpannableString(text + " ");
TextUtils.copySpansFrom((Spanned) text, 0, text.length(),
Object.class, sp, 0);
return sp;
} else {
return text + " ";
}
}
}
}
