这是我使用Foursquare API获得的JSON响应。在这里，我能够使用＆＃34; name＆＃34;提取不同场地的名称。标记并显示为列表视图。但是，问题是我无法从＆＃34; location＆＃34;中提取数据。 JSON响应中给出的标记。
这就是我得到场地名称的方式：
jsonResponse = new JSONObject(json.toString());
jsonResponse = jsonResponse.getJSONObject("response");
// products found
// Getting Array of Products
cinemas = jsonResponse.getJSONArray(TAG_PRODUCTS);//response
// looping through All Products
for (int i = 0; i < cinemas.length(); i++) {
JSONObject venueObject = cinemas.getJSONObject(i);
// String id = venueObject.getString(TAG_PID);
String name = venueObject.getString(TAG_NAME);
prgmName.add(name);
}
JSON回复：

您可以使用getJSONObject again on venueObject`：
试试这个例子：
jsonResponse = new JSONObject(json.toString());
jsonResponse = jsonResponse.getJSONObject("response");
// products found
// Getting Array of Products
cinemas = jsonResponse.getJSONArray(TAG_PRODUCTS);//response
// looping through All Products
for (int i = 0; i < cinemas.length(); i++) {
JSONObject venueObject = cinemas.getJSONObject(i);
String name = venueObject.getString(TAG_NAME);
JSONObject location = venueObject. getJSONObject(TAG_LOCATION);
String countryCode = location.getString("cc");
prgmName.add(name);
}

location是结果数组中的json对象，因此您必须修改代码： -
for (int i = 0; i < cinemas.length(); i++)
{
JSONObject venueObject = cinemas.getJSONObject(i);
String name = venueObject.getString(TAG_NAME);
JSONObject find_location=venueObject.getJSONObject("location");
String lat = find_location.getString("lat");
String lon = find_location.getString("lng");
prgmName.add(name);
}
答案 3 :(得分：1)
jsonResponse = new JSONObject(json.toString());
jsonResponse = jsonResponse.getJSONObject("response");
cinemas = jsonResponse.getJSONArray(TAG_PRODUCTS);//response
for (int i = 0; i < cinemas.length(); i++)
{
JSONObject venue = cinemas.getJSONObject(i);
String name = venue.getString(TAG_NAME);
JSONObject loc = venue. getJSONObject(TAG_LOCATION);
String countryCode = location.getString(3);
String lat = loc.getString("lat");
String lon = loc.getString("lng");
prgmName.add(name);
}

请尝试这种方式，希望这有助于您解决问题。
