这是我的JSON结果，我需要获取textin duration数组。如何获得？
{
"routes" : [
{
"bounds" : {
"northeast" : {
"lat" : 19.0759817,
"lng" : 80.27071789999999
},
"southwest" : {
"lat" : 12.5100381,
"lng" : 72.8776544
}
},
"copyrights" : "Map data ©2015 Google",
"legs" : [
{
"distance" : {
"text" : "1,334 km",
"value" : 1333618
},
"duration" : {
"text" : "17 hours 43 mins",
"value" : 63762
},
"end_address" : "Mumbai, Maharashtra, India",
"end_location" : {
"lat" : 19.0759817,
"lng" : 72.8776544
},
"start_address" : "Chennai, Tamil Nadu, India",
"start_location" : {
"lat" : 13.0826782,
"lng" : 80.27071789999999
},
我已经尝试过使用此代码，因此我可以获得整个distance数组，但是我只需要其中的text元素。
JSONArray one = reader.getJSONArray("routes");
for (int i = 0; i < one.length(); i++) {
JSONObject two = one.getJSONObject(i);
JSONArray three = two.getJSONArray("legs");
for (int j = 0; j < three.length(); j++) {
JSONObject four = three.getJSONObject(j);
String str_long_name=four.getString("distance");
}
}
所以我尝试像这样修改代码
JSONArray one = reader.getJSONArray("routes");
for (int i = 0; i < one.length(); i++) {
JSONObject two = one.getJSONObject(i);
JSONArray three = two.getJSONArray("legs");
for (int j = 0; j < three.length(); j++) {
JSONObject four = three.getJSONObject(j);
JSONArray five = four.getJSONArray("distance");
for (int k= 0; k < five.length(); k++) {
JSONObject six = five.getJSONObject(k);
String str_long_name=six.getString("text");
}
}
}
但它不起作用。它也没有显示任何错误。
该行JSONArray five = four.getJSONArray("distance");是错误的。"distance"是一个JSONObject。
试试下面的代码。
JSONObject five = four.getJSONObject("distance");
String str_long_name=five.getString("text");
System.out.println(str_long_name);
这是测试的完整代码
import org.json.JSONArray;
import org.json.JSONObject;
public class Test {
public static void main(String[] args) {
String str = "{\"routes\":[{\"bounds\":{\"northeast\":{\"lat\":19.0759817,\"lng\":80.27071789999999},\"southwest\":{\"lat\":12.5100381,\"lng\":72.8776544}},\"copyrights\":\"Map data ©2015 Google\",\"legs\":[{\"distance\":{\"text\":\"1,334 km\",\"value\":1333618},\"duration\":{\"text\":\"17 hours 43 mins\",\"value\":63762},\"end_address\":\"Mumbai, Maharashtra, India\",\"end_location\":{\"lat\":19.0759817,\"lng\":72.8776544},\"start_address\":\"Chennai, Tamil Nadu, India\",\"start_location\":{\"lat\":13.0826782,\"lng\":80.27071789999999}}]}]}";
JSONObject reader = new JSONObject(str);
JSONArray one = reader.getJSONArray("routes");
for (int i = 0; i < one.length(); i++) {
JSONObject two = one.getJSONObject(i);
JSONArray three = two.getJSONArray("legs");
for (int j = 0; j < three.length(); j++) {
JSONObject four = three.getJSONObject(j);
JSONObject five = four.getJSONObject("distance");
String str_long_name=five.getString("text");
System.out.println(str_long_name);
}
}
}
}
