Question

我有一个解压缩文件的类，当zip里面没有任何文件夹时，它可以正常工作。如果确实如此，则只会抛出错误。

她的课程：

public class Decompress
{
private String _zipFile;
private String _location;
ZipEntry ze = null;

public Decompress(String zipFile, String location)
{
    _zipFile = zipFile;
    _location = location;

    _dirChecker("");
}

public void unzip()
{
    try
    {
        FileInputStream fin = new FileInputStream(_zipFile);
        ZipInputStream zin = new ZipInputStream(fin);
        while ((ze = zin.getNextEntry()) != null)
        {
            Log.v("Decompress", "Unzipping " + ze.getName()); 

            if (ze.isDirectory())
            {
                _dirChecker(ze.getName());
            }
            else
            {
                FileOutputStream fout = new FileOutputStream(_location + ze.getName());
                for (int c = zin.read(); c != -1; c = zin.read())
                {
                    fout.write(c);
                }

                zin.closeEntry();
                fout.close();
            } 

        }
        zin.close();
    }
    catch (Exception e)
    {
        Log.e("Decompress", "unzip", e);
    }

}

private void _dirChecker(String dir)
{
    File f = new File(_location + dir);

    Log.d("Decompress", f.getAbsolutePath().toString());

    if (!f.isDirectory())
    }
        f.mkdirs();
    }
}

这是我的logcat：

我修复了这个重写代码的问题。我真的不知道发生了什么，因为它的代码相同。但现在它工作得很好。

为什么我的解压缩类不会创建目录？
