Android将list数据通过LitePal保存到本地（集合保存到本地） Android将list数据通过LitePal保存

【Android将list数据通过LitePal保存到本地（集合保存到本地）】有时候我们需要将list集合保存到本地，自己写起来太麻烦，就找到了强大的框架LItePal，git地址https://github.com/LitePalFramework/LitePal

导入jar包就可以使用了，直接上代码：

package com.sdufe.litepal; import java.util.ArrayList; import java.util.List; import org.litepal.crud.DataSupport; import org.litepal.tablemanager.Connector; import android.app.Activity; import android.database.sqlite.SQLiteDatabase; import android.os.Bundle; import android.widget.TextView; import com.sdufe.litepal.model.Student; /** * @author 子墨 * * 2014-10-30 */ public class MainActivity extends Activity { private SQLiteDatabase db; private List list; private Student student; private TextView mInformation; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mInformation = (TextView) findViewById(R.id.student_information); // 生成student表 db = Connector.getDatabase(); initDate(); //保存 DataSupport.saveAll(list); //查找 student = DataSupport.find(Student.class, 3); mInformation.setText("姓名:" + student.getName() + "学号:" + student.getNumber() + "性别:" + student.getSex()); //更新 student=new Student(); student.setName("吸血鬼"); student.update(4); //删除 DataSupport.delete(Student.class, 4); } /** * 表中数据赋值 */ private void initDate() {list.add(new Student(5, "20100854213", "klaus", "男")); list.add(new Student(6, "20100854213", "klaus", "男")); list.add(new Student(7, "20100854213", "klaus", "男")); list.add(new Student(8, "20100854213", "klaus", "男")); list.add(new Student(9, "20100854213", "klaus", "男")); }}

都很简单,主要是人家源码太强大,直接抓来用就好,我的list保存主要是通过saveall实现

还有一点要注意的就是在assets文件夹下新建litepal.xml,不要忘记去配置它:
