对于这样的数据：

首先我们把从服务器取到的数据，里面有个主要的对象mblog,我们用一个对象来存储:
public class MBlog implements Serializable {//保证这个对象是可以序列化的
private static final long serialVersionUID = -3514924369786543050L;
public String uid;
public String favid;
public String mblogid;
public String nick;
public String portrait;
public boolean vip;
public String content;
public String rtrootuid;
public String rtrootid;
public String rtrootnick;
public boolean rtrootvip;
public String rtreason;
public int rtnum;
public int commentnum;
public Date time;
public String pic;
public String src;
public String longitude;// 经度
public String latitude;// 纬度
public boolean equals(Object o) {
if (o == null) return false;
if (o == this) return true;
Class> cla = o.getClass();
if (cla == getClass()) {
MBlog other = (MBlog) o;
if (other.mblogid.equals(mblogid)) return true;
}
return false;
}
public int hashCode() {
return mblogid.hashCode() * 101 >> 12;
}
}
在Activity取到缓存的Path:mCacheDir = this.getCacheDir().getPath();
一般是/data/data/com.example.weibotest/cache
这个是save方法:
public static void save(Object obj, String path) {
try {
File f = new File(path);
/*if(f != null){
f.mkdirs();
f.createNewFile();
}*/
FileOutputStream fos = new FileOutputStream(f);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(obj);
oos.flush();
oos.close();
}
catch (IOException e) {
}
}
读取方法:
public static Object load(String path) {
Object obj = null;
File file = new File(path);
try {
/*if(file != null){
file.mkdirs();
}*/
if (file.exists()) {
FileInputStream fis = new FileInputStream(file);
ObjectInputStream ois = new ObjectInputStream(fis);
try {
obj = ois.readObject();
}
catch (ClassNotFoundException e) {
}
ois.close();
}
}catch (IOException e) {
}
return obj;
}
这样来调用:
public void parseAssertData() {
InputStream is = null;
try {
is = this.getAssets().open("11.xml", Context.MODE_PRIVATE);
int length = is.available();
byte[] buffer = new byte[length];
is.read(buffer);
String temp = new String(buffer);
try {
Object[] array = ParseData.getMBlogList(temp);
List list = (List)array[1];
FileUtils.save(list, mCacheDir+'/'+"001_fav");
List list1 = (List)FileUtils.load(mCacheDir+'/'+"001_fav");
MBlog blog = list1.get(1);
System.out.println("===size="+blog.src);
} catch (Exception e) {
e.printStackTrace();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
