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

Viewed 13007

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 + " ";
    }
}
}
}

I have used Kotlin for a white space tokenizer. This also caters tabs, trailing spaces and line feeds.

object : Tokenizer {
            override fun findTokenStart(text: CharSequence, cursor: Int): Int {
                val spaceIndex = text.indexOfFirst { Character.isWhitespace(it) }
                return if (spaceIndex > cursor)
                    spaceIndex
                else cursor
            }

            override fun findTokenEnd(text: CharSequence, cursor: Int): Int {
                val lastSpaceIndex = text.indexOfLast { Character.isWhitespace(it) }
                return if (lastSpaceIndex > cursor)
                    lastSpaceIndex
                else cursor
            }

            override fun terminateToken(text: CharSequence): CharSequence {
                val i = text.length

                return if (i > 0 && text[i - 1] == ' ') {
                    text
                } else {
                    if (text is Spanned) {
                        val sp = SpannableString("$text ")
                        TextUtils.copySpansFrom(
                            text as Spanned?, 0, text.length,
                            Any::class.java, sp, 0
                        )
                        sp
                    } else {
                        "$text "
                    }
                }
            }

        }
