Question

Hey I Have some Problem to Find Exact Imotion(Facebook) for That Smily Code..
I put my Snippat Code :

private static final HashMap<String, Integer> smilyRegexMap = new HashMap<String, Integer>();

static{
        smilyRegexMap.put( ":-)" , R.drawable.fb_smile);
        smilyRegexMap.put( ":)",R.drawable.fb_smile);
        smilyRegexMap.put( ":-]" , R.drawable.fb_smile);

        smilyRegexMap.put( ":-(", R.drawable.fb_frown);
        smilyRegexMap.put( ":(" , R.drawable.fb_frown);
        smilyRegexMap.put( ":-[" , R.drawable.fb_frown);

        smilyRegexMap.put( ":-P" , R.drawable.fb_tounge);
        smilyRegexMap.put( ":p", R.drawable.fb_tounge);

        smilyRegexMap.put( ":-D" , R.drawable.fb_grin);
        smilyRegexMap.put( ":D" , R.drawable.fb_grin);

        smilyRegexMap.put( ":-O" , R.drawable.fb_gasp);
        smilyRegexMap.put( ":*" , R.drawable.fb_gasp);

        smilyRegexMap.put( ";-)" , R.drawable.fb_wink);
        smilyRegexMap.put( ";)" , R.drawable.fb_wink);
        smilyRegexMap.put( ":putnam:" , R.drawable.fb_putnam);   
    }

//=========================================================

public static CharSequence addSmileySpans(Context ch, CharSequence your_recieved_message)
{
    //smilyRegexMap = new HashMap<Integer, String>();

    System.out.println("==In Spannable Function..........");
    SpannableStringBuilder builder = new SpannableStringBuilder(your_recieved_message);

    System.out.println("==================Size of Smily  : "+ smilyRegexMap.size());
    @SuppressWarnings("rawtypes")
    Iterator it = smilyRegexMap.entrySet().iterator();
    while (it.hasNext()) {
        @SuppressWarnings("rawtypes")
        Map.Entry pairs = (Map.Entry) it.next();

        Pattern mPattern = Pattern.compile((String) pairs.getKey(),Pattern.CASE_INSENSITIVE);
        Matcher matcher = mPattern.matcher(your_recieved_message);

        while (matcher.find()) {
            Bitmap smiley = BitmapFactory.decodeResource(ch.getResources(), ((Integer) pairs.getValue()));
            builder.setSpan(new ImageSpan(smiley), matcher.start(), matcher.end(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
}   
    return builder;
}

And I have Call This Function :

addSmileySpans(this,"Hi i m Happy :-)  ;-)  :p   :putnam:  ");

===>> My Problem is That when i Enter :putnam: then this get Result like

Hi i m Happy

//===========================================

Ookeyyy… Now i Use this Code :::

Bitmap smiley = BitmapFactory.decodeResource(ch.getResources(), ((Integer) pairs.getValue()));
Object[] spans = builder.getSpans(matcher.start(), matcher.end(), ImageSpan.class);
if (spans == null || spans.length == 0) {
   builder.setSpan(new ImageSpan(smiley), matcher.start(), matcher.end(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

But its Give Some Error ::

When Enter :putnam:
its Result is utnam:

1. You should sort you smiles in order from “biggest smile code” to “smallest smile code”.
2. When you find next pattern just check, if this piece of text already covered with span:

Object[] spans = builder.getSpans(matcher.start(), matcher.end(), Object.class);
if (spans == null || spans.length == 0) {
    //add new image span here
}
