Answer 1

This code for change settings of MultiAutoCompleteTextView

ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,codeKeyWords);
MultiAutoCompleteTextView autoCompleteTextView1 = (MultiAutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
autoCompleteTextView1.setAdapter(adapter);
autoCompleteTextView1.setThreshold(1);
autoCompleteTextView1.setTokenizer(new this.CommaTokenizer());

And below that code for make spliting words by space char and \n charactes.. (Why we need this code? Because Normal multiAutoComplete.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); like that and it make spliting the words by ',' character, But our code help you to make that spliting by these characters ' ' and '\n' )

/**
         * This simple Tokenizer can be used for lists where the items are
         * separated by a comma and one or more spaces.
         */
    public static class CommaTokenizer 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) == '\n') {
                i++;
            }

            return i;
        }

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

            while (i < len) {
                if (text.charAt(i) == '\n') {
                    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 + "\n");
                    TextUtils.copySpansFrom((Spanned) text, 0, text.length(),
                                            Object.class, sp, 0);
                    return sp;
                } else {
                    return text + " ";
                }
            }
        }
