一个textview实现两种文字大小以及文字颜色

上边是实现效果，下边是实现代码



tv = (TextView) findViewById(R.id.tv_title);

String text = String.format(“¥%s 门市价：¥%s”, 18.6, 22);

int z = text.lastIndexOf(“门”);

SpannableStringBuilder style = new SpannableStringBuilder(text);

style.setSpan(new AbsoluteSizeSpan(64), 0, 1, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

style.setSpan(new ForegroundColorSpan(Color.parseColor(“#ff0000”)), z, text.length(), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);//

style.setSpan(new AbsoluteSizeSpan(32), z, text.length(), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

tv.setText(style);
