TextView动态改变部分内容和颜色

很简单的东西，怕自己记不住，记录一下~

<string name="title_total_record">核验人数共计:%1$s人</string>tv_count.setText(String.format(getString(R.string.title_total_record), count));// 改变数字颜色SpannableStringBuilder builder = new SpannableStringBuilder(tv_count.getText().toString());  int start = 7;int end = tv_count.getText().length() - 1;//ForegroundColorSpan 为文字前景色，BackgroundColorSpan为文字背景色  ForegroundColorSpan blueSpan = new ForegroundColorSpan(Color.BLUE);builder.setSpan(blueSpan, start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  tv_count.setText(builder);
