SpannableStringBuilder的用法

String reply="小明";SpannableStringBuilder builder = new SpannableStringBuilder(reply);ForegroundColorSpan yellowSpan = new ForegroundColorSpan(context      .getResources().getColor(R.color.red_text));builder.setSpan(yellowSpan, 0, builder.length(),      Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

TextView tv = new TextView(context);

tv.append(“笑话”).append(builder);

结果为笑话小明；
