我有一个文件夹/mnt/sdcard/Bluetooth
,其中包含多个zip
个文件。每个zip文件只包含一个文件。如何将每个zip文件的内容提取到一个新文件中,其中包含每个zip文件的内容?这就是我到目前为止所做的:
public class Main extends Activity {
Object[] arrayOfRarFiles;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String path = "/mnt/sdcard/Bluetooth";
String nameOfFiles;
File folder = new File(path);
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
nameOfFiles = listOfFiles[i].getName();
if (nameOfFiles.endsWith(".zip")
|| nameOfFiles.endsWith(".ZIP")) {
try {
extractFile(nameOfFiles);
} catch (FileNotFoundException e) {
Log.e("EXTRACTFILE SAYS: ", e.getMessage());
}
}
}
}
}
public void extractFile(String path) throws FileNotFoundException {
String zipFileName = "/mnt/sdcard/Bluetooth/" + path;
String extractedFileName = getApplicationContext().getFilesDir()
.getPath().toString()
+ "Finger.FIR";
ZipInputStream inStream = new ZipInputStream(new FileInputStream(
zipFileName));
OutputStream outStream = new FileOutputStream(extractedFileName);
Toast.makeText(getApplicationContext(), zipFileName,
Toast.LENGTH_SHORT).show();
}
最后一个toast,在extractFile
方法中输出每个zip文件的名称。 zip文件夹中的文件是.FIR
个文件
答案 0 :(得分:1)
我认为您可以使用我在另一个SO question中找到的以下功能。
注意根据需要正确设置路径和文件名参数。
public void extractFile(String path) throws FileNotFoundException {
String zipFileName = "/mnt/sdcard/Bluetooth/" + path;
String extractedFileName = getApplicationContext().getFilesDir()
.getPath().toString()
+ "Finger.FIR";
ZipInputStream inStream = new ZipInputStream(new FileInputStream(
zipFileName));
OutputStream outStream = new FileOutputStream(extractedFileName);
unpackZip(path ,zipFileName)
/*Toast.makeText(getApplicationContext(), zipFileName,
Toast.LENGTH_SHORT).show();*/
}
private boolean unpackZip(String path, String zipname)
{
InputStream is;
ZipInputStream zis;
try
{
String filename;
is = new FileInputStream(path + zipname);
zis = new ZipInputStream(new BufferedInputStream(is));
ZipEntry ze;
byte[] buffer = new byte[1024];
int count;
while ((ze = zis.getNextEntry()) != null)
{
// zapis do souboru
filename = ze.getName();
FileOutputStream fout = new FileOutputStream(path + filename);
// cteni zipu a zapis
while ((count = zis.read(buffer)) != -1)
{
fout.write(buffer, 0, count);
}
fout.close();
zis.closeEntry();
}
zis.close();
}
catch(IOException e)
{
e.printStackTrace();
return false;
}
return true;
}
