我应该如何使用截击从 android 中的 sourceJson 获取数据?
How should i get the data from sourceJson in android using volley?
下面是我得到的响应我想从“SourceJson”获取数据我无法理解为什么我在源中得到“”json请帮助我
{
"incomingOrder": [
{
"Namw": 8510,
"Surname": "00",
"mob": "00",
"phone": "000",
"SourceJson": "{\"cart_gst\":30.21,\"instructions\":\"\",\"order_packing_charges\":30,\"cart_igst_percent\":0,\"cart_sgst\":15.1038,}",
"test": "NotSynced",
"test": "DPA",
}]}
试试这个代码:
requestQueue = Volley.newRequestQueue(this);
JsonObjectRequest obreq = new JsonObjectRequest(Request.Method.GET, JsonURL,
// The third parameter Listener overrides the method onResponse() and passes
//JSONObject as a parameter
new Response.Listener<JSONObject>() {
// Takes the response from the JSON request
@Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("incomingOrder");
JSONObject jsonObject = jsonArray.getJSONObject(0);
JSONObject objSourceJson=jsonObject.getJSONObject("SourceJson");
Log.i("IvaSourceJson",objSourceJson.toString());
String cart_gst=objSourceJson.getString("cart_gst");
String instructions=objSourceJson.getString("instructions");
}
// Try and catch are included to handle any errors due to JSON
catch (JSONException e) {
// If an error occurs, this prints the error to the log
e.printStackTrace();
}
}
},
// The final parameter overrides the method onErrorResponse() and passes VolleyError
//as a parameter
new Response.ErrorListener() {
@Override
// Handles errors that occur due to Volley
public void onErrorResponse(VolleyError error) {
Log.e("Volley", "Error");
}
}
);
// Adds the JSON object request "obreq" to the request queue
requestQueue.add(obreq);
由于JSONArray数据是列表类型,最好不要使用jsonArray.getJSONObject(0);
。
使用此代码可获得多个结果,
StringRequest request = new StringRequest(Request.Method.GET, "", new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d("Response", response);
try {
JSONObject object = new JSONObject(response);
JSONArray array = object.getJSONArray("incomingOrder");
for (int i = 0; i < array.length(); i++){
JSONObject object1 = array.getJSONObject(i);
String name = object1.getString("Namw");
String surname = object1.getString("Surname");
String mob = object1.getString("mob");
String phone = object1.getString("phone");
String sourceJson = object1.getString("SourceJson");
String test = object1.getString("test");
String test1 = object1.getString("test");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("Error", error.getMessage());
}
});
Context context;
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
queue.add(request);
在任何方法中对此进行编码,并在需要操作的地方调用该方法。
