获取文件夹大小以及删除指定目录下文件及目录

获取文件夹大小 public static long getFolderSize(java.io.File file){ long size = 0; try { java.io.File[] fileList = file.listFiles(); for (int i = 0; i < fileList.length; i++) { if (fileList[i].isDirectory()) { size = size + getFolderSize(fileList[i]); }else{ size = size + fileList[i].length(); } } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } //return size/1048576; return size; } 删除指定目录下文件及目录 public void deleteFolderFile(String filePath, boolean deleteThisPath) { if (!TextUtils.isEmpty(filePath)) { try { File file = new File(filePath); if (file.isDirectory()) {// 处理目录 File files[] = file.listFiles(); for (int i = 0; i < files.length; i++) { deleteFolderFile(files[i].getAbsolutePath(), true); } } if (deleteThisPath) { if (!file.isDirectory()) {// 如果是文件，删除 file.delete(); } else {// 目录 if (file.listFiles().length == 0) {// 目录下没有文件或者目录，删除 file.delete(); } } } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
