这是我们程序的一小部分，用于列出目录中的文件夹和文件。但我想只显示指定的文件夹及其文件。"/sdcard/folder name/"。我该怎么办。我需要一些帮助。希望这个网站能帮助我

只需添加条件

if ( dir && dir.getName().equals("foldername"))
                  {                  
                      Date lm =new Date(curFile.lastModified());    
                      String filedate = new SimpleDateFormat("dd-MM-yyyy'_'HH:mm:ss").format(lm);   
                           msg +="<b>";                                        
                           msg +="<tr>";                                  
                           msg +="<td>";
                           String path="/sdcard/temp/includes/fold.png";
                           //String p = "/Filemanager/res/drawable-hdpi/ic_launcher.png";
                           msg +="<a "+extra + " href=\"" + encodeUri( uri + files[i] ) + "\">"  +"<img src=\""+ path +"\">"+  

                                   "<span class=\"fontf fcolor_black fsize\">"+ files[i] + "</span></a></td><td>";      
                           msg +="<td class=\"fcolor bfont\">";
                           msg +=filedate;
                           msg += "</font></td>";
                           msg +="<td><input type=\"checkbox\" name=\"chkfolder\" value=" + files[i] + " /></td> ";
                           msg +="</tr>";
                           msg += "</b>";                           


         }

使用for循环，列出所有文件夹和文件。我想只显示所有列出的文件夹中的指定文件夹（sdcard）
