android spinner не может выбрать пункт

Question

У меня есть мой пользовательский базовый адаптер, и я пробую адаптироваться в своем счетчике.

RelativeLayout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="47dp" 
    android:background="#ffffff" > 

    <TextView 
     android:id="@+id/spinnertxt" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_centerVertical="true" 
     android:layout_marginLeft="24dp" 
     android:text="TextView" 
     android:textColor="#777777" 
     android:textSize="17dp" /> 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="5dp" 
     android:layout_height="47dp" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" 
     android:background="#00b827" /> 

</RelativeLayout> 

Spinner:

<Spinner 
    android:id="@+id/pirsaxeobaspinner" 
    android:layout_width="match_parent" 
    android:layout_height="47dp" 
    android:background="@android:color/transparent" 
    android:drawSelectorOnTop="true" 
    android:popupBackground="#ffffff" /> 

BaseAdapter:

public class CustomSpinnerAdapter extends BaseAdapter { 
    private Context mContext; 
    private final ArrayList<String> menu_items_id; 
    UserHolder holder = null; 

    // private final int[] Imageid; 

    private static LayoutInflater inflater = null; 

    public CustomSpinnerAdapter(Context context, ArrayList<String> names) { 
     mContext = context; 

     // this.Imageid = Imageid; 
     this.menu_items_id = names; 
     inflater = (LayoutInflater) mContext 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

    @Override 
    public int getCount() { 

     return menu_items_id.size(); 
    } 

    @Override 
    public Object getItem(int position) { 

     return null; 
    } 

    @Override 
    public long getItemId(int position) { 

     return 0; 
    } 

    @SuppressLint("ViewHolder") 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     View row = convertView; 
     holder = new UserHolder(); 

     if (row == null) { 
      holder = new UserHolder(); 
      row = inflater.inflate(R.layout.custom_spinner_adapter, null); 

      holder.textView = (TextView) row.findViewById(R.id.spinnertxt); 

     } else { 
      holder = (UserHolder) row.getTag(); 
     } 

     holder.textView.setText(menu_items_id.get(position)); 


     row.setTag(holder); 

     return row; 
    } 

    public class UserHolder { 

     public TextView textView; 

    } 

} 

Главный код Java:

public class MyFragment extends Fragment { 
    public final static String TAG = MyFragment.class.getSimpleName(); 

    private Spinner pirsaxeobaspinner; 
    private ArrayList<String> custom_adapter; 
    private CustomSpinnerAdapter my_adapter; 

    public static MyFragment newInstance() { 
     return new MyFragment(); 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.ganayopiereba_fragment, container, 
       false); 
     pirsaxeobaspinner=(Spinner)rootView.findViewById(R.id.pirsaxeobaspinner); 
     custom_adapter=new ArrayList<String>(); 
     custom_adapter.add("Door"); 
     custom_adapter.add("Home"); 



     my_adapter=new CustomSpinnerAdapter(getActivity(), custom_adapter); 
     pirsaxeobaspinner.setAdapter(my_adapter); 

     pirsaxeobaspinner.setOnItemSelectedListener(new OnItemSelectedListener() { 

      @Override 
      public void onItemSelected(AdapterView<?> parent, View view, 
        int position, long id) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onNothingSelected(AdapterView<?> parent) { 
       // TODO Auto-generated method stub 

      } 
     }); 



     return rootView; 
    } 
} 

Я могу адаптировать мой ArrayList в Spinner but Я не могу выбрать элемент из ArrayList.

Вы должны изменить это:

@Override 
public Object getItem(int position) { 

    return menu_items_id.get(position); 
} 

@Override 
public long getItemId(int position) { 

    return position; 
}
