The way to do it would be to implement your own <a href="http://developer.android.com/intl/fr/reference/android/widget/MultiAutoCompleteTextView.Tokenizer.html" rel="nofollow noreferrer">Tokenizer</a>. The reason the comma comes up is because you're using <a href="http://developer.android.com/intl/fr/reference/android/widget/MultiAutoCompleteTextView.CommaTokenizer.html" rel="nofollow noreferrer">CommaTokenizer</a>, which is designed to do exactly that. You can also look at <a href="http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob_plain;f=core/java/android/widget/MultiAutoCompleteTextView.java;hb=HEAD" rel="nofollow noreferrer">the source code for CommaTokenizer</a> if you need a reference for how to implement your own SpaceTokenizer.

I have used Kotlin for a white space tokenizer. This also caters tabs, trailing spaces and line feeds.
<pre><code>object : Tokenizer {
 override fun findTokenStart(text: CharSequence, cursor: Int): Int {
 val spaceIndex = text.indexOfFirst { Character.isWhitespace(it) }
 return if (spaceIndex &gt; cursor)
 spaceIndex
 else cursor
 }

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

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

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

I'm doing a simple program using <code>MultiAutoCompleteTextView</code> to prompt the common words when I input several letters. 

code:

<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>

Now,when I input 'a' and choose "abcd" but the result become to "abcd,". How to replace the comma with a space?

Thank you!
