文件中添加如下方法
//get the icon of the  file
    public Drawable getFileIcon1(FileInfo fileInfo) {
        String mAPKFilePath="";
    File apkFile=fileInfo.getFile();
       mAPKFilePath=apkFile.getPath();
        if(mContext==null){
        return null;
    }
            mPm=mContext.getPackageManager();
            PackageInfo info = mPm.getPackageArchiveInfo(mAPKFilePath,
                PackageManager.GET_ACTIVITIES);
            if (info != null) {
                   ApplicationInfo appInfo = info.applicationInfo;
                    appInfo.sourceDir = mAPKFilePath;
                appInfo.publicSourceDir = mAPKFilePath;
                   try {
                        return appInfo.loadIcon(mPm);
                  } catch (OutOfMemoryError e) {
                        System.out.println("Fail loadIcon : " + e);
                    }
            }
        return null;
   }
在getIcon（**）方法中添加如下语句：

if(!fileInfo.isDirectory()){
             String filename=fileInfo.getFileName();
             if(filename.endsWith(".apk")){
                    Drawable apkIcon=getFileIcon1(fileInfo);
                  if(apkIcon!=null){
                         Bitmap.Config config=apkIcon.getOpacity()!=PixelFormat.OPAQUE?Bitmap.Config.ARGB_8888:Bitmap.Config.RGB_565;  //将Drawable转变为Bitmap
                 Bitmap bitmap=Bitmap.createBitmap(48,48, config);
                         Canvas canvas=new Canvas(bitmap);
             apkIcon.setBounds(0, 0, 48, 48);
                         apkIcon.draw(canvas);
                         icon= bitmap;          
                     }
             }   
    }          
fileInfo.isDirectory()  //判断文件是否是目录
