Android 将文件压缩成ZIP
核心API: ZipOutputStream
public static void ZipFolder(String srcFileString, String zipFileString) {//创建ZIPtry {ZipOutputStream outZip = new ZipOutputStream(new FileOutputStream(new File(zipFileString + "" + System.currentTimeMillis() + ".zip")));//创建文件File file = new File(srcFileString);//压缩ZipFiles(file.getParent() + File.separator, file.getName(), outZip);//完成和关闭outZip.finish();outZip.close();} catch (Exception e) {e.printStackTrace();}}
private static void ZipFiles(String folderString, String fileString, ZipOutputStream zipOutputSteam) {try {if (zipOutputSteam == null)return;File file = new File(folderString + fileString);if (file.isFile()) {ZipEntry zipEntry = new ZipEntry(fileString);FileInputStream inputStream = new FileInputStream(file);zipOutputSteam.putNextEntry(zipEntry);int len;byte[] buffer = new byte[4096];while ((len = inputStream.read(buffer)) != -1) {zipOutputSteam.write(buffer, 0, len);}zipOutputSteam.closeEntry();} else {//文件夹String fileList[] = file.list();//没有子文件和压缩if (fileList.length <= 0) {ZipEntry zipEntry = new ZipEntry(fileString + File.separator);zipOutputSteam.putNextEntry(zipEntry);zipOutputSteam.closeEntry();}//子文件和递归for (int i = 0; i < fileList.length; i++) {ZipFiles(folderString + fileString + "/", fileList[i], zipOutputSteam);}}} catch (Exception e) {e.printStackTrace();}}
