代码片段：
ZipFile zipFile=null;
try {
zipFile = new ZipFile("test.xml");//传入的不是个压缩文件
} catch (IOException e) {
System.out.println("[ThemeResource][InputStream]error =>" + e.getMessage());
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
try {
if(null!=zipFile){
zipFile.close();//传入的不是压缩文件时，ZipFile的构造方法没有执行完zipFile=null，无法执行到这里
zipFile=null;
}
} catch (IOException e2) {
}
}
ZipFile构造方法
Zipfile构造方法代码 收藏代码
public ZipFile(File file, int mode) throws IOException {
filename = file.getPath();
if (mode != OPEN_READ && mode != (OPEN_READ | OPEN_DELETE)) {
throw new IllegalArgumentException("Bad mode: " + mode);
}
if ((mode & OPEN_DELETE) != 0) {
fileToDeleteOnClose = file;
fileToDeleteOnClose.deleteOnExit();
} else {
fileToDeleteOnClose = null;
}
raf = new RandomAccessFile(filename, "r");
<span style="color: #ff6600;">readCentralDir();//异常在这里抛出，源码上没有地方看到调用raf的close方法。</span>
guard.open("close");
}
RandomAccessFile构造方法：
public RandomAccessFile(File file, String mode) throws FileNotFoundException {
int flags;
if (mode.equals("r")) {
flags = O_RDONLY;
} else if (mode.equals("rw") || mode.equals("rws") || mode.equals("rwd")) {
flags = O_RDWR | O_CREAT;
if (mode.equals("rws")) {
// Sync file and metadata with every write
syncMetadata = true;
} else if (mode.equals("rwd")) {
// Sync file, but not necessarily metadata
flags |= O_SYNC;
}
} else {
throw new IllegalArgumentException("Invalid mode: " + mode);
}
this.mode = flags;
this.fd = IoBridge.open(file.getAbsolutePath(), flags);
// if we are in "rws" mode, attempt to sync file+metadata
if (syncMetadata) {
try {
fd.sync();
} catch (IOException e) {
// Ignored
}
}
guard.open("close");//............
}
这种问题怎么解？？ Android 压缩 zipFile
补充：移动开发 , Android
