我是靠谱客的博主文静钢笔，最近开发中收集的这篇文章主要介绍java通过for循环获取list中想要的内容，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

获取list有几条内容通过循环取值当i小于list.size时i加一

 List<nrbean> li=new ArrayList<nrbean>();// po=null;
		        li=dd.chakan(data);
		      String jsonObject="";
		      ///通过下面方法能取出list中想要的数值
		       for(int i=0;i<li.size();i++){   
		       int id;
		        	nrbean nb=li.get(i);
			  
			  
			   System.out.print("------------"+nb.getId());
			     //   }

i表示当前是第几条list
将第i条内容赋给对象nb

nrbean nb=li.get(i);

在通过对象nb get nb中的内容
下面是nrbean

package bean;

import java.text.SimpleDateFormat;

public class nrbean {
    private int chakancichu;
	public int getChakancichu() {
		return chakancichu;
	}
	public void setChakancichu(int chakancichu) {
		this.chakancichu = chakancichu;
	}
	private String username;
	private String nr;
	private double latitude;//纬度
	private double longitude;//经度
	private String data;
	private int id;
	private String img;
	public String getImg(){
		return img;
	}
	public void setImg(String img){
		this.img=img;
	}
	private String url;
public String getUrl() {
		return url;
	}
	public void setUrl(String url) {
		this.url = url;
	}
	//	
	private int jici;
	private String hfdate;
	private String hfusername;
	private String hfopenid;
	private String hfnr;
	private String fatieopenid;
	public String getFatieopenid() {
		return fatieopenid;
	}
	public void setFatieopenid(String fatieopenid) {
		this.fatieopenid = fatieopenid;
	}
	public String getHfnr(){
		return hfnr;
	}
	public void setHfnr(String hfnr){
		this.hfnr=hfnr;
	}
	public int getJici() {
		return jici;
	}
	public void setJici(int jici) {
		this.jici = jici;
	}
	public String getHfdate() {
		return hfdate;
	}
	public void setHfdate(String hfdate) {
		this.hfdate = hfdate;
	}
	public String getHfusername() {
		return hfusername;
	}
	public void setHfusername(String hfusername) {
		this.hfusername = hfusername;
	}
	public String getHfopenid() {
		return hfopenid;
	}
	public void setHfopenid(String hfopenid) {
		this.hfopenid = hfopenid;
	}
	
	
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getData() {
		return data;
	}
	public void setData(String data) {
		this.data = data;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getNr() {
		return nr;
	}
	public void setNr(String nr) {
		this.nr = nr;
	}
	public double getLatitude() {
		return latitude;
	}
	public void setLatitude(double latitude) {
		this.latitude = latitude;
	}
	public double getLongitude() {
		return longitude;
	}
	public void setLongitude(double longitude) {
		this.longitude = longitude;
	}
