【问题描述】：
我的 JSON：
{
"response_code": 200,
"error": false,
"train_name": "KCG YPR EXP",
"train_num": "17603",
"pnr": "1234567890",
"failure_rate": 19.346153846153847,
"doj": "20-8-2015",
"chart_prepared": "Y",
"class": "SL",
"total_passengers": 2,
"train_start_date": {
"month": 8,
"year": 2015,
"day": 20
},
"from_station": {
"code": "KCG",
"name": "KACHEGUDA"
},
"boarding_point": {
"code": "KCG",
"name": "KACHEGUDA"
},
"to_station": {
"code": "YPR",
"name": "YESVANTPUR JN"
},
"reservation_upto": {
"code": "YPR",
"name": "YESVANTPUR JN"
},
"passengers": [
{
"no": 1,
"booking_status": "S7,58,GN",
"current_status": "S7,58",
"coach_position": 9
},
{
"no": 2,
"booking_status": "S7,59,GN",
"current_status": "S7,59",
"coach_position": 9
}
]
}
到目前为止我做了什么：
if(jsonStr!=null)
{
try
{
JSONObject object=new JSONObject(jsonStr);
JSONArray jsonArray=object.getJSONArray("passengers");
for (int i=0;i<=jsonArray.length();i++)
{
JSONObject o=jsonArray.getJSONObject(i);
int no= Integer.parseInt(o.optString("no").toString());
String booking_status=o.getString("Booking Status");
String current_status=o.getString("Current Status");
String coach_position=o.getString("Coach Position");
JSONObject data=o.getJSONObject("details");
String train_name = data.getString("Train Name");
int train_num = Integer.parseInt(data.optString("train number").toString());
int pnr = Integer.parseInt(data.optString("pnr").toString());
String chart_prepared = data.getString("Chart Prepared");
int total_passengers=Integer.parseInt(data.optString("total passengers").toString());
JSONObject date=data.getJSONObject("tarin_start_date");
int month=Integer.parseInt(data.optString("month").toString());
int year=Integer.parseInt(data.optString("year").toString());
int day=Integer.parseInt(data.optString("day").toString());
JSONObject co=date.getJSONObject("from_station");
String code=co.getString("code");
String name=co.getString("name");
JSONObject co1=co.getJSONObject("boarding_point");
String code1=co1.getString("code");
String name1=co1.getString("name");
JSONObject co2=co1.getJSONObject("to_station");
String code2=co2.getString("code");
String name2=co2.getString("name");
JSONObject co3=co2.getJSONObject("from_station");
String code3=co3.getString("code");
String name3=co3.getString("name");
HashMap<String,String> dtail=new HashMap<>();
dtail.put("no", String.valueOf(no));
dtail.put("Booking Staus",booking_status);
dtail.put("Current Staus",current_status);
dtail.put("Coach Positon",coach_position);
dtail.put("Train Name",train_name);
dtail.put("Train Number", String.valueOf(train_num));
dtail.put("pnr", String.valueOf(pnr));
dtail.put("chart prepared",chart_prepared);
dtail.put("total passengers", String.valueOf(total_passengers));
dtail.put("month", String.valueOf(month));
dtail.put("year", String.valueOf(year));
dtail.put("day", String.valueOf(day));
dtail.put("code",code);
dtail.put("name",name);
dtail.put("code",code1);
dtail.put("name",name1);
dtail.put("code",code2);
dtail.put("name",name2);
dtail.put("code",code3);
dtail.put("name",name3);
dataList.add(dtail);
}
}
catch (final JSONException e) {
Log.e(TAG, "Json parsing error: " + e.getMessage());
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Json parsing error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
});
}
}
else
{
Log.e(TAG, "Couldn't get json from server.");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Couldn't get json from server. Check LogCat for possible errors!",
Toast.LENGTH_LONG).show();
}
});
}
return null;
}
【问题讨论】：
-
那么你的问题在哪里？
-
在 run() 方法数组索引 0 超出范围 [0..0] 时出错
-
先修复你的代码，你有很多不同的键，在 JSIN 中你有
total_passengers但在代码中你称之为data.optString("total passengers"等等 -
那么我该怎么做，你可以通过更正它来发布代码......
