JAVA和C实现文件搜索（递归和文件过滤器）

  public static void findFile(File allList,String endName,List<File> filenames){               FileFilter filefilter = new ExtensionFileFilter(endName);         // 创建fileArray名字的数组  ，存储allList目录下的所有文件          File[] fileArray= allList.listFiles();             // 如果传进来一个以文件作为对象的allList 返回           if(null==fileArray){                  return ;              }           File[] files = null;        if((allList.getAbsolutePath().indexOf("sd")!=-1)||(allList.getAbsolutePath().indexOf("SD")!=-1))        {        files = allList.listFiles(filefilter);        if(files.length>0)        {        System.out.println("目录: "+files[0].getAbsolutePath());         filenames.add(files[0]);//找到所搜索文件，添加到存储器        }                }              // 偏历目录下的文件            for(int i=0;i<fileArray.length;i++){                // 如果是个目录                if(fileArray[i].isDirectory()){                 String dir = fileArray[i].getAbsolutePath();                 if(dir.length() - dir.replaceAll("/", "").length() > 3)                  break;             findFile(fileArray[i].getAbsoluteFile(),endName,filenames);   //递归               }         }         }     public static class ExtensionFileFilter implements FileFilter {    private String extension;    public ExtensionFileFilter(String extension)     {    this.extension = extension;    }          public boolean accept(File file)     {    if(file.isDirectory( ))    {    return false;    }        String name = file.getName();// find the last    return name.equals(extension);//搜索特定名称的文件        /*int index = name.lastIndexOf(".");//搜索特定后缀名文件    if(index == -1) {    return false;    }else     if(index == name.length( ) -1)     {    return false;    }     else     {    return this.extension.equals(name.substring(index+1));    }*/    }    }     public static void getpath(){    String dir = "/";    File file = new File(dir);     List<File> filenames = new ArrayList<File>();    findFile(file,"hello_sd.key",filenames);    //File[] files = (File[]) filenames.toArray();    System.out.println("file:="+filenames.get(0));//打印搜索文件，filenames中存储找到的文件信息    }

 需求一改，立马就得变换程序，orz，下面是用C实现搜索，无奈还是很笨啊

void  FindFile(const char *dirName,char* desFileName, char* desPath){    DIR* dir = NULL;    struct dirent *d_ent = NULL;    struct stat sb;char currfile[1024]={0};    dir = (DIR*)opendir(dirName);    if(dir == NULL)        return;    int i;    while ( (d_ent = readdir(dir))!= NULL )       {           if(strncmp(d_ent->d_name, ".", 1)==0 || strncmp(d_ent -> d_name,"",1) == 0)               continue;           sprintf(currfile,"%s/%s",dirName,d_ent->d_name);        //   LOGI("currfile=%s",currfile);      //     LOGI("d_ent->d_name = %s, desFileName = %s",d_ent->d_name,desFileName);           stat(currfile, &sb);      //     LOGI("sb.st_nlink = %d",sb.st_nlink);           if(S_ISDIR(sb.st_mode))//如果是目录文件，递归调用           {          // LOGI("This is dir");           if(sb.st_nlink>=6)           continue;           FindFile(currfile,desFileName,desPath);           }else if(strcmp(desFileName,d_ent->d_name) == 0)//是普通文件，比较是否是目标文件           {               LOGI("desPath = %s",dirName);               strncpy(desPath,dirName,strlen(dirName) + 1);               break;           }      }    closedir(dir);}
