java如何将模型类parcelable对象从片段传递到活动？
我想将Parcelable模型类对象从片段传递到活动。在片段中，我正在传递AsyncTaskpostExecute()方法。在活动中，我需要在listview中附加模型类对象dat。我尝试使用arraylist和Serializableaslo，但它不起作用。请需要一个如何制作的建议
我的片段类：
public class PlantPOSearch extends Fragment {
Button go;
PlantPOModel plantPOModel = new PlantPOModel();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.plantpo_search, container, false);
go = (Button) rootView.findViewById(R.id.ordergo);
go.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MyAsyncTask myAsyncTask = new MyAsyncTask();
myAsyncTask.execute();
}
});
return rootView;
}
class MyAsyncTask extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
}
protected String doInBackground(String... params) {
InputStream inputStream = null;
HttpURLConnection urlConnection = null;
String line = "", response = "";
try
{
//int plantnum = Integer.parseInt(params[0]);
String url1="http://192.168.1.5:8002/sap/opu/odata/sap/ZMM_PO_APP_SRV/POHeaderSet?$filter=Plant%20eq%20%271000%27";
URL url = new URL(url1);
String authorizationString = "Basic " + Base64.encodeToString(("abaper" + ":" + "erp@786").getBytes(), Base64.NO_WRAP);
URL urlToken = new URL("http://192.168.1.5:8002/sap/opu/odata/sap/ZSALES_APP_SRV/");
String token = new TokenGeneration().getToken(authorizationString, urlToken);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Authorization", authorizationString);
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.setRequestProperty("Accept", "application/json");
urlConnection.setRequestProperty("X-CSRF-Token", token);
urlConnection.setRequestMethod("GET");
Log.d("Token", token);
int statusCode = urlConnection.getResponseCode();
Log.d("Response code", "" + statusCode);
if (statusCode == HttpsURLConnection.HTTP_OK) {
inputStream = new BufferedInputStream(urlConnection.getInputStream());
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
while ((line = bufferedReader.readLine()) != null) {
response += line;
}
if (null != inputStream) {
inputStream.close();
}
Log.d("Plant Response", response);
}
Gson gson = new Gson();
plantPOModel = gson.fromJson(response,PlantPOModel.class);
Log.d("company code",plantPOModel.getD().getResults()[0].getCompanyCode());
Log.d("Doc Number", plantPOModel.getD().getResults()[0].getPurchaseDocNo());
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
Intent intent = new Intent(getActivity().getApplicationContext(), POList.class);
ArrayList<PlantPOModel> arrayList = new ArrayList<>();
arrayList.add(plantPOModel);
intent.putParcelableArrayListExtra("Plant",arrayList);
startActivity(intent);
}catch (Exception e){
e.printStackTrace();
}
}
}
}
