Android TextView 实现文字大小不同和文字颜色不同

效果图如下：

关键代码如下：

[java] view plaincopy

1. StringBuffer sb = new StringBuffer();  
2.                 if(day > 0) {  
3.                     sb.append("<a href=\"1\">");  
4.                     sb.append(""+day);  
5.                     sb.append("</a>");  
6.                     sb.append(""+Global.getString(R.string.unit_Day2));  
7.                 }  
8.   
9.                 sb.append("<a href=\"2\">");  
10.                 if(hour > 9) {  
11.                     sb.append(" "+hour);  
12.                 } else {  
13.                     sb.append(" 0"+hour);  
14.                 }  
15.                 sb.append("</a>");  
16.                 sb.append(""+Global.getString(R.string.unit_Hour2));  
17.   
18.                 sb.append("<a href=\"3\">");  
19.                 if(minute > 9) {  
20.                     sb.append(" "+minute);  
21.                 } else {  
22.                     sb.append(" 0"+minute);  
23.                 }  
24.                 sb.append("</a>");  
25.                 sb.append(""+Global.getString(R.string.unit_Minute2));  
26.   
27.                 sb.append("<a href=\"4\">");  
28.                 if(second > 9) {  
29.                     sb.append(" " + second);  
30.                 } else {  
31.                     sb.append(" 0" + second);  
32.                 }  
33.                 sb.append("</a>");  
34.                 sb.append(""+Global.getString(R.string.unit_Second));  
35.   
36.                 int end = sb.length();  
37.                 SpannableString ss = new SpannableString(Html.fromHtml(sb.toString()));  
38.                 URLSpan[] urls = ss.getSpans(0, end, URLSpan.class);  
39.   
40.                 String resultStr = sb.toString();  
41.                 Pattern p_html = Pattern.compile(REGEX_HTML, Pattern.CASE_INSENSITIVE);  
42.                 Matcher m_html = p_html.matcher(resultStr);  
43.                 resultStr = m_html.replaceAll(""); // 过滤html标签  
44.                 SpannableString span = new SpannableString(resultStr);  
45.                 for (URLSpan url : urls) {  
46.                     int startIndex = ss.getSpanStart(url);  
47.                     int endIndex = ss.getSpanEnd(url);  
48.                     // 原字两倍大小  
49.                     span.setSpan(new AbsoluteSizeSpan(Global.dpToPx(24)), startIndex, endIndex,  
50.                             Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  
51.                     // 设置样式2  
52.                     span.setSpan(new ForegroundColorSpan(Color.WHITE),  
53.                             startIndex, endIndex,  
54.                             Spannable.SPAN_EXCLUSIVE_INCLUSIVE);  
55.                     // 设置样式3  
56.                     span.setSpan(new StyleSpan(Typeface.BOLD),  
57.                             startIndex, endIndex,  
58.                             Spannable.SPAN_EXCLUSIVE_INCLUSIVE);  
59.                 }  
60.   
61.                 mBottomLL2_Detail.setText(span);  

说明：

1.主要原理为使用SpannableString来做多样式的String给TextView显示

2.用到<a href>标签的原因是为了做到国际化，因为span是按照index来多样化的，所以需要用href来标识多样化的index
