Android : Don't show image in TextView by ImageSpan in Android

I want to show an image in TextView as a smiley. I have a method that gets a string and adds ImageSpans to a CharSequence that replace textual emoticons such as :-) with a graphical version.

public Spannable addSmileySpans(CharSequence text) {
    SpannableStringBuilder builder = new SpannableStringBuilder(text);

    Matcher matcher = mPattern.matcher(text);
    while (matcher.find()) {
        int resId = mSmileyToRes.get(matcher.group());
        builder.setSpan(new ImageSpan(mContext, resId),
                        matcher.start(), matcher.end(),
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    }

    return builder;
}

Then I use it on my adapter:

viewHolder.txtReceivedBody.setText(parser.addSmileySpans(message.body));

Also, here defined TextView elemnt:

<TextView
            android:id="@+id/txtReceivedBody"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@+id/imgReceivedDirection"
            android:layout_marginRight="30dp"
            android:background="@drawable/selector_conversation_received"
            android:minHeight="40dp"
            android:paddingLeft="10dp"
            android:paddingRight="10dp"
            android:paddingTop="4dp"
            android:paddingBottom="4dp"
            android:textSize="18sp"
            android:autoLink="all"
            android:gravity="right"/>

Unfortunately, didn't show image in TextView and only show a main string. What should I do to solve it?
