setContentView(R.layout.main);               TextView textView  = (TextView) findViewById(R.id.textview);  
            SpannableString ss = new SpannableString("abc");  
            Drawable d = getResources().getDrawable(R.drawable.icon32);  
 
 
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());  
            ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);  
            ss.setSpan(span, 0, 3, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);  
 
 
            textView.setText(ss);
