Android TextView 支持BBCode的显示

BBCode：
BBCode的解释请看这里https://en.wikipedia.org/wiki/BBCode
如何能是Android TextView支持BBCode呢，首先是需要将包含BBCode的字符串转换成Html的形式，然后TextView来显示Html String。网上也有开源库支持BBCode转Html，如kefirbb library，试过之后发现都是转成了style标签，但是Android TextView是不支持style标签的，无奈只能借鉴大神们的方法，自己来写。关于Android TextView显示Html，以及支持的Html tags，请看上一篇http://blog.csdn.net/u010057266/article/details/46972253
新建BBCodeMaps类，在这里获取BBCode的Maps列表，你也可以添加自己需要的Tag

新建解析类BBCodeParse，其实就是字符串替换的工作，为了支持
List Tag: [list] [*]Entry 1 [*]Entry 2 [/list] or [list] *Entry 1 *Entry 2 [/list]
做了一些额外的处理。
public class BBCodeParse { public static String bbcode2Html(String text) { String html = text; Map<String, String> bbMap = BBCodeMaps.getBBcodeMap(); for (Map.Entry entry : bbMap.entrySet()) { if (entry.getKey().toString().contains("\\[list\\](.+?)\\[/list\\]")) { html = bbcodeListParse(html); } html = html.replaceAll(entry.getKey().toString(), entry.getValue().toString()); } return html; } /** * Parse List Tag: [list] [*]Entry 1 [*]Entry 2 [/list] or [list] *Entry 1 *Entry 2 [/list] * @param html html text * @return html */ private static String bbcodeListParse(String html) { String listTagStart = "[list]"; String listTagEnd = "[/list]"; String asteriskTag1 = "[*]"; String asteriskTag2 = "*"; int pos = 0; // Only replace * which contains in [list]...[/list] while (html.indexOf(listTagStart, pos) != -1) { int sPos = html.indexOf(listTagStart, pos); int ePos = html.indexOf(listTagEnd, sPos) + listTagEnd.length(); pos = ePos; boolean isAsteriskTag = false; String str1 = html.substring(sPos, ePos); String str2 = html.substring(sPos, ePos); // This must be first step if (str1.contains(asteriskTag1)) { while (str1.contains(asteriskTag1)) { str1 = str1.replaceAll("\\[\\*\\](.+?)\\[", "<li>$1</li>\\["); } isAsteriskTag = true; } if (html.contains(asteriskTag2)) { str1 = str1.replaceAll("\\*", asteriskTag1); while (str1.contains(asteriskTag1)) { str1 = str1.replaceAll("\\[\\*\\](.+?)\\[", "<li>$1</li>\\["); } isAsteriskTag = true; } if (isAsteriskTag) { html = html.substring(0, html.indexOf(str2)) + str1 + html.substring(html.indexOf(str2) + str2.length(), html.length()); } } return html; }}
