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!


Solution

  • 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 + " ";
        }
    }
    }
    }
