 String imagename="1.png";      
    mSendText.getText().insert(cursorPosition, index);
    if (index.contains(imagename)) {
        index.replace(cs,":-)");
        mSendText.setText(index);

    } else {

String is immutable in Java. If you want to replace something in a String, you have to use this:

index = index.replace(cs,":-)");

i have to ask one more thing.,can we convert spannble object into string?? – User11 May 12 '14 at 08:47
Spannable has a `toString()` method likje every other Java class, so yes you can. However I do not know the output you will get. But since you are talking about emoticons, have you looked at this question? http://stackoverflow.com/questions/14900449/storing-spannable-to-a-string – Axel May 12 '14 at 10:13
