XMPP群聊截图后在历史消息中显示图片

截图后保存到xml中是用图片的信息来进行保存的，只需要通过图片的路径在本地找到对应的图片，加载到历史消息显示面板中即可。

代码如下

Java代码  

1. String[] strs = body.split(" ");  
2.                         for(int i = 0; i < strs.length; i++){  
3.                             //表情  
4.                             if(strs[i].contains(":") || strs[i].contains("(") || strs[i].contains(")") ){  
5.                                 try{  
6.                                 URL emoticon_url = emoticonManager.getEmoticonURL(emoticonManager.getEmoticon(strs[i]));  
7.                                 String emoticon_path = emoticon_url.getPath();  
8.                                 emoticon_path = "file:///C|/" + emoticon_path.substring(emoticon_path.indexOf(":/") + 2);  
9.                                 strs[i] = "<img src='"+ emoticon_path + "'/>";  
10.                             }catch (Exception e) {  
11.                             }finally{  
12.                             }  
13.                             }  
14.                             //截图  
15.                             if(strs[i].contains("Tmp://")){  
16.                                    String tmpPath = strs[i].substring(strs[i].indexOf("Tmp://") + 6, strs[i].indexOf("#"));  
17.                                    File rootPath =  new File(Spark.getSparkUserHome(), "/tempImages");  
18.                                     File f = new File(rootPath.getAbsolutePath(), tmpPath);  
19.                                     URL fileURL=null;  
20.                                     try {  
21.                                         fileURL = f.toURI().toURL();//本地URL  html可识别  
22.                                     } catch (MalformedURLException e) {  
23.                                         // TODO Auto-generated catch block  
24.                                         e.printStackTrace();  
25.                                     }  
26.                                     String file_path=fileURL.getPath();  
27.                                     file_path = "file:///C|/" + file_path.substring(file_path.indexOf(":/") + 2);  
28.                                     if(f.exists()){  
29.                                         strs[i] = "<img src='"+ file_path + "'/>";  
30.                                     }else{  
31.                                         strs[i] = "<img src='"+ f.getAbsolutePath() + "'/>";  
32.                                     }  
33.                                       
34.                             }  
35.                             if(strs[i].contains("<img>")){//自定义的标签<img>  
36.                                 strs[i]= strs[i].substring(0,strs[i].indexOf("<img>"));  
37.                             }  
38.                             builder.append(strs[i]);  
39.                         }  

 效果如图所示：
