如果你希望你的新记录在列表视图刷新

然后u有记录的音频/视频后运行这些代码块每次的。 while（fs.getfetchstatus（）！= true）{my_shares = fs.findSongs（Environment.getExternalStorageDirectory（））;

 } 
     if (mySongs != null) { 
      dialog.dismiss(); 
     } 

     mySongs = fs.getsonglist(); 

     items = new String[mySongs.size()]; 
     for (int i = 0; i < mySongs.size(); i++) { 
      items[i] = mySongs.get(i).getName().toString().replace(".3gp", "");

所以将此代码复制并粘贴在私人无效stopRecording（）{}在结束.. 可能会工作...
