회 전자를 사용하여 항목을 선택하고 새로 고칩니다.회 전자 항목을 사용할 때 어댑터가 새로 고쳐지지 않습니다.
예 : 전체를 선택하면 모든 항목이 표시됩니다. "Sell In"을 선택하면 항목에 대한 판매 만 표시됩니다. 따라서 스피너 선택에 따라 항목이 필터링되어 표시되어야합니다.
필터링을 시도했지만 제외하지 않았습니다. 어댑터가 항목을 새로 고치지 않습니다.
다음은 코드입니다.
MainActivity :
public class Activities extends BaseActivity {
private RecyclerView recyclerView;
private Spinner spinner;
String[] countriesList = {"All", "Sell In", "Registrasi", "Re-Registrasi"};
ActivitiesListAdapter adapter;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
contentView = inflater.inflate(R.layout.activity_activities_list, null);
insertPoint.addView(contentView);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
spinner = (Spinner) findViewById(R.id.spinner);
adapter = new ActivitiesListAdapter(getData(), this);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this, OrientationHelper.VERTICAL, false);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setAdapter(adapter);
CustomSpinnerAdapter customAdapter=new CustomSpinnerAdapter(this,countriesList);
spinner.setAdapter(customAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String items = adapterView.getItemAtPosition(i).toString();
// adapter.getFilter().filter(items);
final List<RetailerActivities> filteredModelList2 = adapter.filter2(getData(), items);
//adapter.setFilter(filteredModelList2);
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}
//the first item to be compared in Spinner.
public static List<RetailerActivities> getData() {
List<RetailerActivities> list = new ArrayList<>();
list.add(new RetailerActivities("Sell In", "Selli Cell", "13/06/2017 09:10", R.drawable.ic_tag));
list.add(new RetailerActivities("Registrasi", "Farras Cell", "13/06/2017 09:10", R.drawable.ic_registrasi));
list.add(new RetailerActivities("Re-Registrasi", "Farras Cell", "13/06/2017 09:10", R.drawable.ic_registrasi));
list.add(new RetailerActivities("POSM & Visibility", "Farras Cell", "13/06/2017 09:10", R.drawable.ic_poms));
list.add(new RetailerActivities("Sell In", "Selli Cell", "13/06/2017 09:10", R.drawable.ic_tag));
return list;
}

회 전자 항목을 선택한 경우 어디에서 결과를 표시 하시겠습니까? –
예 @vikaskumar 답변을 편집했습니다. 당신이 지금 그것을 얻을 수 있기를 바랍니다. 드롭 다운에서 값을 선택하면 어댑터를 필터링해야합니다. – Shiv
