阿尔派710的刷机包 解压后 根目录的900多M的 pkg文件怎么解压
对于解压阿尔派710刷机包根目录下的pkg文件,可以考虑使用Java中的ZipInputStream类进行解压。具体操作步骤如下:
String filePath = "path/to/pkg/file";
FileInputStream fis = new FileInputStream(filePath);
ZipInputStream zis = new ZipInputStream(fis);
ZipEntry entry = zis.getNextEntry();
while (entry != null) {
if (entry.isDirectory()) {
File dir = new File("path/to/output/directory" + entry.getName());
if (!dir.exists()) {
dir.mkdirs();
}
} else {
File file = new File("path/to/output/directory" + entry.getName());
FileOutputStream fos = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int len;
while ((len = zis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
fos.close();
}
entry = zis.getNextEntry();
}
zis.close();
fis.close();
完整的代码如下所示:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class Unzip {
public static void main(String[] args) {
try {
String filePath = "path/to/pkg/file";
FileInputStream fis = new FileInputStream(filePath);
ZipInputStream zis = new ZipInputStream(fis);
ZipEntry entry = zis.getNextEntry();
while (entry != null) {
if (entry.isDirectory()) {
File dir = new File("path/to/output/directory" + entry.getName());
if (!dir.exists()) {
dir.mkdirs();
}
} else {
File file = new File("path/to/output/directory" + entry.getName());
FileOutputStream fos = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int len;
while ((len = zis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
fos.close();
}
entry = zis.getNextEntry();
}
zis.close();
fis.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
需要注意的是,如果目标解压目录不存在,则需要先创建它,否则会抛出FileNotFoundException异常。此外,在使用完输入流和ZipInputStream对象后,需要考虑关闭它们以释放资源。
