android - 可搜索微调器使我的应用程序在多任务处理时崩溃

Question

我在图书馆工作 Searchable Spinner ，但是如果我在打开微调器时按下 android 主页按钮或多任务按钮，应用程序会崩溃并在屏幕上打印:“不幸的是，Appname 已停止。”

我的 fragment Activity :

public class buscadorFragment extends Fragment implements View.OnClickListener {


public Button BotonRecargar;
public IndeterminateRoadRunner UCargando;
public TextView TextoPrueba;
public TextView TextoError;


private OnFragmentInteractionListener mListener;

public SearchableSpinner SpCateg;
public SearchableSpinner SpUbic;

String[] CategoriasArray = {"Categorias"};
String[] UbicacionesArray ={"Ubicaciones"};

ArrayAdapter<String> CatspinnerAdapter;
ArrayAdapter<String> UbicspinnerAdapter;



public buscadorFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_buscador, container, false);
CatspinnerAdapter = new ArrayAdapter<>(getContext(), android.R.layout.simple_spinner_item, CategoriasArray);
    CatspinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    SpCateg.setAdapter(CatspinnerAdapter);
    CatspinnerAdapter.notifyDataSetChanged();


    UbicspinnerAdapter = new ArrayAdapter<>(getContext(), android.R.layout.simple_spinner_item, UbicacionesArray);
        UbicspinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    SpUbic.setAdapter(UbicspinnerAdapter);
    UbicspinnerAdapter.notifyDataSetChanged();



    SpCateg.setTitle("Categoría");
    SpCateg.setPositiveButton("Cancelar");

    SpUbic.setTitle("Ubicación");
    SpUbic.setPositiveButton("Cancelar");

    return view;    
} 

我的 fragment 布局:

只添加

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:weightSum="2">

        <com.toptoche.searchablespinnerlibrary.SearchableSpinner
            android:layout_width="match_parent"
            android:layout_height="45dp"
            android:layout_weight="1"
            android:id="@+id/Category_Spinner" />

        <com.toptoche.searchablespinnerlibrary.SearchableSpinner
            android:layout_width="match_parent"
            android:layout_height="45dp"
            android:layout_weight="1"
            android:id="@+id/Ubication_Spinner" />


    </LinearLayout>

有 logcat:

仅当微调器打开时崩溃，否则应用程序继续运行。我是新手，想学习，所以在此先感谢。

看起来这是库的问题，因为其他用户在 Github 上报告了同样的问题。要解决此问题，您可以关闭 onPause() 方法中的 searchableListDialog。

于是在SearchableListDialog.java中编写如下代码

@Override
    public void onPause()
    {
        super.onPause();
        dismiss();
    }
