title: How to replace the comma with a space when I use the "MultiAutoCompleteTextView"
body: <p>I'm doing a simple program using <code>MultiAutoCompleteTextView</code> to prompt the common words when I input several letters. </p>
  
  <p>code:</p>
  
  <pre><code>    ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(
              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",
      };
  </code></pre>
