一个基于xml格式数据保存的本地缓存方案,支持对象缓存兼容列表缓存,减弱对sqlite的依赖.
MainActivity.class:
public class MainActivity extends AppCompatActivity {
// 数据列表
private ArrayList<Model> modelList;
// 数据对象
private Stu mStu;
// 列表缓存
private SpLocalCache<ListCache> listSpLocalCache;
// 对象缓存
private SpLocalCache<Stu> objectSpLocalCache;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化缓存
listSpLocalCache = new SpLocalCache<>(ListCache.class, Model.class);
objectSpLocalCache = new SpLocalCache<>(Stu.class);
// 初始化数据源
modelList = new ArrayList<>();
mStu = new Stu();
// 模拟数据
// 列表
Model mModel = new Model();
mModel.setName("张三");
mModel.setAge(18);
mModel.setAddress("北京");
modelList.add(mModel);
mModel = new Model();
mModel.setName("李四");
mModel.setAge(20);
mModel.setAddress("深圳");
modelList.add(mModel);
mModel = new Model();
mModel.setName("王五");
mModel.setAge(25);
mModel.setAddress("广州");
modelList.add(mModel);
// 对象
mStu.setStuName("庾澄庆");
mStu.setStuAge(49);
mStu.setStuAddress("**");
// 缓存List数据
ListCache<Model> mListCache = new ListCache<>();
mListCache.setObjList(modelList);
// 缓存数据
listSpLocalCache.save(this, mListCache);
objectSpLocalCache.save(this, mStu);
// 读取缓存数据
listSpLocalCache.read(this, new SpLocalCache.LocalCacheCallBack() {
@Override
public void readCacheComplete(Object obj) {
System.out.println("---------------------------list cache----------------------------------");
System.out.println("dddddddddddddddddd obj = " + obj);
if (obj != null){
ListCache<Model> mReadCache = (ListCache<Model>) obj;
if (mReadCache != null){
ArrayList<Model> modelArrayList = mReadCache.getObjList();
for(int i=0;i<modelArrayList.size();i++){
System.out.println("ddddddddddddd model[" + i + "].name = " + modelArrayList.get(i).getName());
System.out.println("ddddddddddddd model[" + i + "].age = " + modelArrayList.get(i).getAge());
System.out.println("ddddddddddddd model[" + i + "].address = " + modelArrayList.get(i).getAddress());
}
}
}
}
});
objectSpLocalCache.read(this, new SpLocalCache.LocalCacheCallBack() {
@Override
public void readCacheComplete(Object obj) {
System.out.println("---------------------------object cache----------------------------------");
System.out.println("dddddddddddddddddd obj = " + obj);
if (obj != null){
Stu stu = (Stu) obj;
System.out.println("ddddddddddddd stu.name = " + stu.getStuName());
System.out.println("ddddddddddddd stu.age = " + stu.getStuAge());
System.out.println("ddddddddddddd stu.address = " + stu.getStuAddress());
}
}
});
