How to replace the comma with a space when I use the "MultiAutoCompleteTextView"

I'm doing a simple program using

MultiAutoCompleteTextView
to prompt the common words when I input several letters.

code:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_dropdown_item_1line,
ary);
MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView) findViewById(R.id.editText);
textView.setAdapter(adapter);

textView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

private String[] ary = new String[] {
"abc",
"abcd",
"abcde",
"abcdef",
"abcdefg",
"hij",
"hijk",
"hijkl",
"hijklm",
"hijklmn",
};


Now,when I input 'a' and choose "abcd" but the result become to "abcd,". How to replace the comma with a space?

Thank you!

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;
}

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 + " ";
    }
}
}
}
