我正在解析这个json并让它像这样循环。
public void addpaqs() {
try {
JSONArray array = new JSONArray(paqsresponse);
for (int i = 0; i < array.length(); i++) {
JSONObject row = array.getJSONObject(i);
tolongitude = row.getString("to_longitude");
tolatitude = row.getString("to_latitude");
creatorfirstname = row.getString("creator_first_name");
creatorlastname = row.getString("creator_last_name");
paqtype = row.getString("paq_type");
startdate = row.getString("start_date");
enddate = row.getString("end_date");
fromplace = row.getString("from_country");
toplace = row.getString("to_country");
fromcity = row.getString("from_city");
tocity = row.getString("to_city");
String price = row.getString("price");
fromlatitude = row.getString("from_latitude");
fromlongitude = row.getString("from_longitute");
tolatitude = row.getString("to_latitude");
tolongitude = row.getString("to_longitude");
Log.d("fromplace", fromplace);
double tolongdouble = Double.parseDouble(tolongitude);
double tolatdouble = Double.parseDouble(tolatitude);
Paqs paqs = new Paqs(R.drawable.cross,R.drawable.accountimage, creatorfirstname+creatorlastname,price, paqtype,startdate+"/"+enddate,fromplace+fromcity,toplace+tocity);
paqsarray.add(paqs);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
我创建了自定义适配器，以便能够将此JSON中的所有信息放入ListView，这是我的自定义适配器类;
package com.paqqy;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.List;
public class CustomAdapter extends BaseAdapter {
Context context;
protected List<Paqs> listCars;
LayoutInflater inflater;
public CustomAdapter(Context context, List<Paqs> listCars) {
this.listCars = listCars;
this.inflater = LayoutInflater.from(context);
this.context = context;
}
public int getCount() {
return listCars.size();
}
public Paqs getItem(int position) {
return listCars.get(position);
}
public long getItemId(int position) {
return listCars.get(position).getDrawableId();
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = this.inflater.inflate(R.layout.card_item,
parent, false);
holder.name = (TextView) convertView
.findViewById(R.id.tv_name_id);
holder.paqtype = (TextView) convertView
.findViewById(R.id.tv_paq_id);
holder.txtPrice = (TextView) convertView
.findViewById(R.id.tv_price_id);
holder.date= (TextView) convertView
.findViewById(R.id.tv_date_id);
holder.from= (TextView) convertView
.findViewById(R.id.tv_from_id);
holder.to= (TextView) convertView
.findViewById(R.id.tv_to_id);
holder.imgCar = (ImageView) convertView.findViewById(R.id.iv_general_id);
holder.paqsimage = (ImageView) convertView.findViewById(R.id.iv_paq_general_id);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Paqs paqs = listCars.get(position);
holder.name.setText(paqs.getFirstname());
holder.paqtype.setText(paqs.getPaqtype());
holder.date.setText(paqs.getDate());
holder.from.setText(paqs.getFrom());
holder.to.setText(paqs.getTo());
holder.txtPrice.setText(" $" + paqs.getPrice());
holder.imgCar.setImageResource(paqs.getDrawableId());
holder.paqsimage.setImageResource(paqs.getPaqsimage());
return convertView;
}
private class ViewHolder {
TextView name;
TextView paqtype;
TextView date;
TextView from;
TextView to;
TextView txtPrice;
ImageView imgCar;
ImageView paqsimage;
}
}
这是我的适配器获取列表的Paqs.class文件
package com.paqqy;
public class Paqs {
private int drawableId;
private String firstname;
private String lastname;
private String price;
private String paqtype;
private String date;
private String from,to;
private int paqsimage;
public Paqs(int drawableId,int paqsimage, String firstname, String price,String paqtype,String date,String from,String to) {
super();
this.drawableId = drawableId;
this.paqsimage = paqsimage;
this.firstname = firstname;
this.price = price;
this.paqtype = paqtype;
this.date = date;
this.from = from;
this.to = to;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public void setDate(String date) {
this.date = date;
}
public void setFrom(String from){
this.from = from;
}
public void setTo(String to){
this.to = to;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public void setPaqtype(String paqtype) {
this.paqtype = paqtype;
}
public void setPrice(String price) {
this.price = price;
}
public String getFirstname() {
return firstname;
}
public String getLastname() {
return lastname;
}
public String getFrom(){
return from;
}
public String getTo(){
return to;
}
public String getPrice() {
return price;
}
public String getPaqtype() {
return paqtype;
}
public String getDate(){
return date;
}
public int getDrawableId() {
return drawableId;
}
public void setDrawableId(int drawableId) {
this.drawableId = drawableId;
}
public int getPaqsimage() {
return paqsimage;
}
public void setPaqsimage(int paqsimage) {
this.paqsimage = paqsimage;
}
}
问题是循环之后我只在ListView内看到2个值，而且仅此而已......但是在我的JSON我有大量的值，你可以看到，所以我做错了什么在我的循环？我不知道也不知道问题是什么。谢谢你！
答案 0 :(得分：0)
所以，有一件事情可能发生，对不起，我没有＆＃39;我真的想读你所有的json，我只是猜测tolongitude = row.getString("to_longitude");这行可以抛出一个异常，就像代码中获取值的所有行一样，所以，如果没有带有该名称的字符串其中一个对象，他不会补充。 解决方案：use object.optString(name)，只需将opt添加到您的所有获取方法中，这应该可行，如果有帮助，请发布给我
