我有一個類來解壓縮文件，它工作正常時，沒有任何文件夾裏面。如果這樣做，那麼它只是拋出錯誤。爲什麼我的解壓縮類不能創建目錄？
赫斯我的課：
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();
}
}
這裏是我的logcat：
