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:
