findViewById null zurück in Fragmente Klasse

Question

• Die findViewById() kehrt null in Fragment-Klasse. Die Toast für die ImageButton zeigt etwas, aber das Objekt für Switch dh mySwitch kehrt null ... Bitte helfen ....

  public MyAdapter(Context context, List<ListItems> values) { 
  
      super(context, R.layout.list_item, values); 
  } 
  
  @Override 
  public View getView(int position, View convertView, ViewGroup parent) { 
  
      View v = convertView; 
      LayoutInflater inflater = LayoutInflater.from(getContext()); 
  
      if(v == null){ 
       v = inflater.inflate(R.layout.list_item, parent, false); 
      } 
  
      ListItems currLoc = LocationList.get(position); 
  
      TextView theTextView = (TextView) v.findViewById(R.id.list_item_textview); 
      theTextView.setText(currLoc.getLocation()); 
  
      TextView theTextView2 = (TextView) v.findViewById(R.id.list_item_textviewP); 
      theTextView2.setText(currLoc.getProfile()); 
  
      ImageView theImageView = (ImageView) v.findViewById(R.id.imageview1); 
      Toast.makeText(getActivity(), "image view="+theImageView, Toast.LENGTH_SHORT).show(); 
      theImageView.setImageResource(R.drawable.bullet); 
  
  
      Switch mySwitch=(Switch) v.findViewById(R.id.onoff); 
      Toast.makeText(getActivity(), ""+mySwitch, Toast.LENGTH_SHORT).show(); 
  
  
      return v; 
  }
