微调器的 Onitemclicklistner 如何将 id 传递给 android 中的下一个微调器
Onitemclicklistner for spinner how to pass the id to next spinner in android
嗨，下面的代码描述了微调器。在微调器中，我显示了不同类型的建筑物名称，以供调用 Api。根据响应，我将建筑物的名称设置为微调器。

现在，我的问题是，当用户从 spinner.I 中选择任何建筑物名称时，想要从微调器中获取 ID，然后将其传递给下一个微调器。
谁能帮我看看怎么做。

"Nice umang" 的回答听起来不错。
对我来说，我看得更远，我更深入。
我建了一个 class BaseTextSpinnerAdapter<T> extends ArrayAdapter
我有覆盖方法 getItemId 并使其成为我想要的 return。
@Override
public long getItemId(int position) {
if (mItems.get(position) != null) {
return mItems.get(position).getObjectId();
}
return -1;
}
首先创建一个模型Class喜欢Building
public class Building{
private String id;
private String name:
public Building(String id, String name){
this.id = id;
this.name = name;
}
public String getId(){
return id;
}
public String getName(){
return name;
}
}
然后在您的 activity 中创建一个 ArrayList 类型 Building，如下所示
// declear it in global scope
ArrayList<Building> buildingList;
// and initialize it in `onCreate`
buildingList = new ArrayList <> ();
并在您的 API 回复中使用此 arraylist，如下所示。
userCall.enqueue(new Callback<Managebuilding> () {
@Override
public void onResponse(Call <Managebuilding> call, Response <Managebuilding> response) {
if (response != null && response.code ( ) == 200 && response.isSuccessful ( )) {
Managebuilding building = response.body ();
String Lists=new Gson ( ).toJson (response.body ());
// JSONArray jsonArray=new JSONArray ();
// JSONObject jsonObject = null;
try {
JSONObject jsonObject = new JSONObject (Lists);
JSONArray result = jsonObject.getJSONArray ("list");
System.out.println (result);
//JSONArray result = jsonArray.getJSONArray ("ID");
arrayList = new ArrayList <> ();
for (int i = 0; i <result.length(); i++) {
String id=result.getJSONObject (i).getString ("ID");
String name =result.getJSONObject (i).getString ("Name");
// here you have create object of building using id and name
Building building = new Building(id, name)
buildingList.add(building);
arrayList.add(name);
}
ArrayAdapter <String> adapter = new ArrayAdapter <String> (getContext (),android.R.layout.simple_spinner_item, arrayList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
}catch (JSONException e) {
e.printStackTrace ( );
}
progressDialog.dismiss ( );
} else {
progressDialog.dismiss ( );
Log.d ("Response errorBody", String.valueOf (response.errorBody ( )));
}
}
@Override
public void onFailure(Call<Managebuilding> call, Throwable t) {
// lv.setAdapter (adapter);
System.out.println("onFailure");
System.out.println(t.fillInStackTrace());
progressDialog.dismiss();
Toast.makeText(getActivity (), "Some error occurred -> ", Toast.LENGTH_LONG).show();;
// progressDialog.dismiss();
}
});
}
现在您必须像下面那样修改您的 setOnItemSelectedListener。
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener () {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// here you can retrive you building info by positon
Building building = buildingList.get(position)
String id = building.getId();
String name = building.getName();
// Now you can use your id or name to do whatever you want.
System.out.println (id);
System.out.println (name);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
}
