首先,要获取嵌套GET响应的数据,我们需要创建一个异步任务(AsyncTask)。在这个任务中,我们将使用HTTPURLConnection对象来获取嵌套响应。我们可以在onPostExecute()方法中解析响应并将它们添加到列表或使用它们进行其他操作。
以下是这个过程的代码示例:
public class GetNestedData extends AsyncTask
@Override
protected String doInBackground(Void... params) {
String response = null;
try {
URL url = new URL("http://example.com/api/nested-data");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.connect();
InputStream stream = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
StringBuilder builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
response = builder.toString();
reader.close();
stream.close();
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
@Override
protected void onPostExecute(String response) {
if (response != null) {
try {
JSONObject jsonObject = new JSONObject(response);
// Get the nested data
JSONArray array = jsonObject.getJSONArray("nested_data");
// Loop through the array and get the required data
for (int i = 0; i < array.length(); i++) {
JSONObject nestedObject = array.getJSONObject(i);
String name = nestedObject.getString("name");
String address = nestedObject.getString("address");
// Do whatever you want with the data here
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
在这个例子中,我们从服务器获取了一个包含嵌套数据的JSON响应。我们使用HttpURLConnection来获取数据,然后在doInBackground()方法中解析它们。在onPostExecute()方法中,我们可以使用嵌套的响应数据进行操作。 您可以按需修改此示例以满足您
