String text = " my font1 , font 2 ";   
Typeface font,font1;
font = Typeface.createFromAsset(getAssets(), "font.TTF");
font1 = Typeface.createFromAsset(getAssets(), "font1.TTF");
Spannable s = new SpannableString(text);
s.setSpan(new CustomTypefaceSpan("", font), curpos, endpos, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
s.setSpan(new CustomTypefaceSpan("", font1), curpos, endpos, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
.
.
.
.
//want to chage variable text here !

Try using the SpannableStringBuilder class. "This is the class for text whose content and markup can both be changed." It sounds like you need a mutable class.

It's unclear precisely how you want to change the text, but I use SpannableStringBuilder like this to insert additional text at the beginning of some text that is html. Once you have your string builder object there are sufficient methods available to modify things.

 Spanned spHtml = Html.fromHtml(myHtmlString, Html.FROM_HTML_MODE_LEGACY);
 SpannableStringBuilder sb = new SpannableStringBuilder(spHtml);
 sb.insert(0, "text to be inserted");

Can you try something like this :

public void updateTextView(String toThis) {
    TextView textView = (TextView) findViewById(R.id.textView);
    textView.setText(toThis);
// Put here your span, ...
}

And call this function when you want update your textView
