LinearLayout列表展示

步骤:
1.在layout中写一个LinearLayout布局，并且有id

                2.MainActivity中获取数据库的所有数据

3.把数据中中的数据,通过TextVew添加到LinearLayout对象

package com.sqf.sql;

import java.util.List;

import com.sqf.sql.dao.PersonDao;
import com.sqf.sql.entities.Person;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		LinearLayout llList = (LinearLayout) findViewById(R.id.ll_list);
		
		PersonDao dao = new PersonDao(this);  
		List personList = dao.queryAll(); //获取表中的所有数据
		
		if(personList != null){
			TextView tv;
			for(Person person:personList){
				//向线性布局中添加一个textView
				tv = new TextView(this);
				tv.setText(person.toString());
				tv.setTextSize(18);
				llList.addView(tv);
			}
		}
		
	}

 
}

package com.sqf.sql.entities;

public class Person {
	
	private int id;
	private String name;
	private int age;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
	}
	public Person(int id, String name, int age) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
	}
	public Person() {
		super();
	}
	
	
	
	
}
