我想用齐射从这个json获取所有请求
最佳答案
您可以使用Gson相当轻松地完成操作，而在这里youtube tutorial
这是一个小代码示例
public void getFromServer(){
final String url =YOUR URL HERE
final ArrayList<ElementEntity> arrayOfCities = new ArrayList<>();
// prepare the Request
final JsonArrayRequest getRequest = new JsonArrayRequest(Request.Method.GET,url,null,
new Response.Listener<JSONArray>()
{
@Override
public void onResponse(JSONArray response) {
// display response
Log.d("Response", response.toString());
for(int i = 0; i< response.length();i++){
try {
JSONObject jresponse = response.getJSONObject(i);
YourObject yourObject = gson.fromJson(jresponse.toString(),YourObject .class);
arrayOfYourObject.add(yourObject);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
Log.d("Error.Response", "error");
}
});
// add it to the RequestQueue
queue.add(getRequest);
}
