Android实现文件或文件夹压缩成.zip格式压缩包
本文实例为大家分享了Android压缩文件和文件夹的方法，供大家参考，具体内容如下
/**
* 压缩文件和文件夹
*
* @param srcFileString 要压缩的文件或文件夹
* @param zipFileString 压缩完成的Zip路径
* @throws Exception
*/
public static void ZipFolder(String srcFileString, String zipFileString) throws Exception {
//创建ZIP
ZipOutputStream outZip = new ZipOutputStream(new FileOutputStream(zipFileString));
//创建文件
File file = new File(srcFileString);
//压缩
LogUtils.LOGE("---->"+file.getParent()+"==="+file.getAbsolutePath());
ZipFiles(file.getParent()+ File.separator, file.getName(), outZip);
//完成和关闭
outZip.finish();
outZip.close();
}
/**
* 压缩文件
*
* @param folderString
* @param fileString
* @param zipOutputSteam
* @throws Exception
*/
private static void ZipFiles(String folderString, String fileString, ZipOutputStream zipOutputSteam) throws Exception {
LogUtils.LOGE("folderString:" + folderString + "\n" +
"fileString:" + fileString + "\n==========================");
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);
}
}
}
