文件夹是文件未压缩

Question

我已经实现了压缩文件夹或文件然后下载并将其保存到内存中。我的问题是，下载没有任何错误，但我没有收到 Zip 文件，如果我点击下载的文件，它会显示：

Can't show

或

Can't display message.

我的代码：

String fileName = tvtitle.getText().toString();
        String fileExtension = tvtype.getText().toString();
        File imageDirectory = new File(Path);
        imageDirectory.mkdirs();
        int fileLength = connection.getContentLength();
        String _path = Path;
        input = connection.getInputStream();
        File outputFile = new File(_path, fileName + fileExtension);
        FileOutputStream fos = new FileOutputStream(outputFile);
        ZipOutputStream zos = new ZipOutputStream(fos);
        File srcFile = new File(input.toString());
        byte[] buffer = new byte[1024];
        zos.putNextEntry(new ZipEntry(srcFile.getName()));
        int length;
        while ((length = input.read(buffer)) > 0) {

            zos.write(buffer, 0, length);

        }
        zos.closeEntry();
        input.close();
        zos.close();

就是不知道这个变量的类型是什么"input"

我认为您应该将 FileInputStream（读取源文件）与 FileOutputStream（设置为 destination/zip 文件）配对。

这行代码：

File outputFile = new File(_path, fileName + fileExtension);

你的输出一定是 .zip 文件吧？所以，应该是：

File outputFile = new File(_path, fileName + ".zip");

或类似的东西

而且会是这样

String fileName = tvtitle.getText().toString();
String fileExtension = tvtype.getText().toString();
File imageDirectory = new File(Path);
FileInputStream fis = new FileInputStream(imageDirectory);
ZipEntry zipEntry = new ZipEntry(fileName);

FileOutputStream fos = new FileOutputStream("test.zip");
ZipOutputStream zos = new ZipOutputStream(fos);
zos.putNextEntry(zipEntry);
byte[] bytes = new byte[1024];
int length;
    while ((length = fis.read(bytes)) >= 0) {
        zos.write(bytes, 0, length);
    }
zos.closeEntry();
fis.close();
zos.close();
fos.close();
