我有一个错误,而我尝试提取,我已经保存在我的资产文件夹中的.zip的文件,错误出现,因为我的文件有字符N。当我试图让下一个条目的错误抛出: zipIs.getNextEntry()
私人无效loadzip(字符串的文件夹,为InputStream的InputStream)抛出IOException异常
{
ZipInputStream zipIs =新ZipInputStream(InputStream的);
ZipEntry的泽= NULL;
INT I = 0;
而((泽= zipIs.getNextEntry())!= NULL){
FileOutputStream中FOUT =新的FileOutputStream(文件夹+/+ ze.getName());
byte []的缓冲区=新的字节[1024];
INT长度= 0;
而((长度= zipIs.read(缓冲液))大于0){
fout.write(缓冲液,0,长度);
}
zipIs.closeEntry();
fout.close();
}
zipIs.close();
}
使用 zip4j
私人无效loadZip(字符串zipFileName,弦乐目的地)
{
ZipFile的zip文件= NULL;
名单< FileHeader里>标题= NULL;
尝试 {
zip文件=新的ZipFile(zipFileName);
标题= zipFile.getFileHeaders();
}赶上(抛出:ZipException E){
// TODO自动生成的catch块
e.printStackTrace();
}
如果(头!= NULL)
{
的for(int i = 0; I< headers.size();我++)
{
尝试 {
zipFile.extractFile(headers.get(i)中,目的地);
}赶上(抛出:ZipException E){
// TODO自动生成的catch块
e.printStackTrace();
}
}
}
}

如果您想从资产加载(我的情况),你必须把你的拉链到SD卡文件夹中,之后将其解压缩:
私人的ArrayList<字符串> moveZipsFromAssets(字符串[] zipsAssets,弦乐目的地)
{
ArrayList的<字符串>拉链=新的ArrayList<字符串>();
的for(int i = 0; I< zipsAssets.length;我++)
{
InputStream中的InputStream =的getInputStream(zipsAssets [I]);
Log.d(标记,+ zipsAssets [I]);
档案文件=新的文件(目标+/+ zipsAssets [I]);
尝试 {
FileOutputStream中的OutputStream =新的FileOutputStream(文件);
INT读= 0;
字节[]字节=新字节[1024];
而((读= inputStream.read(字节))!= -1){
outputStream.write(字节,0,读);
}
outputStream.close();
zips.add(目的地+/+ zipsAssets [I]);
}赶上(FileNotFoundException异常E){
// TODO自动生成的catch块
e.printStackTrace();
}赶上(IOException异常E){
// TODO自动生成的catch块
e.printStackTrace();
}
}
回报拉链;
}
例如使用(我们有一个文件夹的资产/ myZipsFolder /哪里都是拉链):`的ArrayList
zipsExternos = moveZipsFromAssets(getAssets()。表(myZipsFolder),
Environment.getExternalStorageDirectory()+/ myZipsFolder);
//并加载拉链:
的for(int i = 0; I< zipsExternos.size();我++)
loadZip(zipsExternos.get(ⅰ),Environment.getExternalStorageDirectory()+/ myZipsFolder);
解决方案
您需要使用第三方库如的 zip4j 。他们ZipInputStream实现支持非UTF8的文件名。
编辑,因为 ZipInputStream(InputStream的,字符集)
是不是在Android的使用。的
I have an error while I try to extract the files of a .zip that I have stored in my assets folder, the error appear because my file have the character ñ. The error throws when I try to get next entry: zipIs.getNextEntry()
private void loadzip(String folder, InputStream inputStream) throws IOException
{
ZipInputStream zipIs = new ZipInputStream(inputStream);
ZipEntry ze = null;
int i=0;
while ((ze = zipIs.getNextEntry()) != null) {
FileOutputStream fout = new FileOutputStream(folder +"/"+ ze.getName());
byte[] buffer = new byte[1024];
int length = 0;
while ((length = zipIs.read(buffer))>0) {
fout.write(buffer, 0, length);
}
zipIs.closeEntry();
fout.close();
}
zipIs.close();
}
Using zip4j
private void loadZip(String zipFileName, String destination)
{
ZipFile zipFile = null;
List<FileHeader> headers = null;
try {
zipFile = new ZipFile(zipFileName);
headers = zipFile.getFileHeaders();
} catch (ZipException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(headers != null)
{
for(int i=0;i<headers.size();i++)
{
try {
zipFile.extractFile(headers.get(i),destination);
} catch (ZipException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
.................................................................................................................................
If you want to load from assets (my case), you have to move your zip to sdcard folder and after that extract it:
private ArrayList<String> moveZipsFromAssets(String[] zipsAssets, String destination)
{
ArrayList<String> zips = new ArrayList<String>();
for(int i=0;i<zipsAssets.length;i++)
{
InputStream inputStream = getInputStream(zipsAssets[i]);
Log.d(tag, ""+zipsAssets[i]);
File file = new File(destination+"/"+zipsAssets[i]);
try {
FileOutputStream outputStream = new FileOutputStream(file);
int read = 0;
byte[] bytes = new byte[1024];
while ((read = inputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, read);
}
outputStream.close();
zips.add(destination+"/"+zipsAssets[i]);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return zips;
}
example use (we have a folder assets/myZipsFolder/ where are all the zips): `ArrayList
zipsExternos = moveZipsFromAssets(getAssets().list("myZipsFolder"),
Environment.getExternalStorageDirectory()+"/myZipsFolder");
//and load the zips:
for(int i=0;i<zipsExternos.size();i++)
loadZip(zipsExternos.get(i),Environment.getExternalStorageDirectory()+"/myZipsFolder");
解决方案
You need to use a third-party library such as zip4j. Their ZipInputStream implementation supports non-UTF8 file names.
Edited because ZipInputStream(InputStream, Charset)
is not available in Android.
