我正在创建一个从服务器接收JSON数据的应用程序，用户将从Spinner中选择一个值，如0,1,2 ...依此类推，在数字选择的基础上，JSON将返回用户定义的数据索引像0,1 ..我不知道如何解析Android中的内部JSON数据
json = new JSONObject(JSONParser.Result);
JSONArray jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
Log.d("JSON Algo Result", json.toString());
if (jArray!=null) {
for (int i = 0; i < jArray.length(); i++) {
jsonarray = jArray.getJSONArray(i);
if (jsonarray != null) {
for (int j = 0; j < jsonarray.length(); i++){
if(i==0) {
jsonarray = jArray.getJSONArray(j);
_stop.setName(jsonarray.getString(0));
StopElement.Stop_name_list.add(_stop.getName());
}
}
} else {
break;
}
}
} else {
return null;
}

我像这样解决了我的问题
try {
int count = 0;
if (success == 1) {
json = new JSONObject(JSONParser.Result);
jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
for (int i = 0; i < jArray.length(); i++) {
count = count + 1;
// Log.d("Counter", String.valueOf(count));
get_path.add(String.valueOf(count));
jsonarray = jArray.getJSONArray(i);
Log.d("path Array", jsonarray.toString());
if (getitemno>0) {
getpath = jArray.getJSONArray(getitemno);
for (int j = 0; j < getpath.length(); j++) {
getresult = getpath.getJSONArray(j);
_stop.setName(getresult.getString(0));
_map.setLat(getresult.getDouble(1));
_map.setLng(getresult.getDouble(2));
