当我使用"MultiAutoCompleteTextView"时如何用空格替换逗号

Question

MultiAutoCompleteTextView当我输入几个字母时,我正在做一个简单的程序来提示常用词.

码:

    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",
    };

现在,当我输入'a'并选择"abcd"但结果变为"abcd"时.如何用空格替换逗号？

谢谢!

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 + " ";
    }
}
}
}
