第一个案例为大家分享了Android遍历特定目录下所有文件,包含子目录的,并删除最新创建的。
private boolean deleteLastFromFloder(String path) {boolean success = false;try {ArrayList<File> images = new ArrayList<File>();getFiles(images, path);File latestSavedImage = images.get(0);if (latestSavedImage.exists()) {for (int i = 1; i < images.size(); i++) {File nextFile = images.get(i);if (nextFile.lastModified() > latestSavedImage.lastModified()) {latestSavedImage = nextFile;}}Log.e("brady", "images = " + latestSavedImage.getAbsolutePath());success = latestSavedImage.delete();}} catch (Exception e) {e.printStackTrace();}return success;}private void getFiles(ArrayList<File> fileList, String path) {File[] allFiles = new File(path).listFiles();for (int i = 0; i < allFiles.length; i++) {File file = allFiles[i];if (file.isFile()) {fileList.add(file);} else if (!file.getAbsolutePath().contains(".thumnail")) {getFiles(fileList, file.getAbsolutePath());}}}
第二个案例介绍了文件夹遍历Android代码,供大家参考,具体内容如下
package com.once; import java.io.File;import java.util.ArrayList;import java.util.LinkedList;/** * 文件夹遍历 * @author once * */public class DirTraversal { //no recursionpublic static LinkedList<File> listLinkedFiles(String strPath) {LinkedList<File> list = new LinkedList<File>();File dir = new File(strPath);File file = dir.listFiles();for (int i = 0; i < file.length; i++) {if (file.isDirectory())list.add(file);elseSystem.out.println(file.getAbsolutePath());}File tmp;while (!list.isEmpty()) {tmp = (File) list.removeFirst();if (tmp.isDirectory()) {file = tmp.listFiles();if (file == null)continue;for (int i = 0; i < file.length; i++) {if (file.isDirectory())list.add(file);elseSystem.out.println(file.getAbsolutePath());}} else {System.out.println(tmp.getAbsolutePath());}}return list;}//recursionpublic static ArrayList<File> listFiles(String strPath) {return refreshFileList(strPath);} public static ArrayList<File> refreshFileList(String strPath) {ArrayList<File> filelist = new ArrayList<File>();File dir = new File(strPath);File files = dir.listFiles(); if (files == null)return null;for (int i = 0; i < files.length; i++) {if (files.isDirectory()) {refreshFileList(files.getAbsolutePath());} else {if(files.getName().toLowerCase().endsWith("zip"))filelist.add(files);}}return filelist;}}
