Individuelle Adapter für Listview innerhalb Fragment

-1

So wurde nach ich die Antwort von @AndiGeeky auf custom adapter for listview in fragment Android Individuelle Adapter für Listview innerhalb Fragment

Aber es hat nicht funktioniert. Hier ist mein Code.

public class TabLectura extends Fragment implements View.OnClickListener { 

private View view; 
private ListView list_calllog; 
private static final String ARG_SECTION_NUMBER = "section_number"; 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
{ 
    if(view==null) 
    { 
     view=inflater.inflate(R.layout.tab_lectura, container,false); 
    } 
    else 
    { 
     ViewGroup parent = (ViewGroup) view.getParent(); 
     parent.removeView(view); 
    } 

    ClassOrdenDetalle detalle = new ClassOrdenDetalle(123,"321",15,15); 
    ArrayList<ClassOrdenDetalle> ordeness = new ArrayList<>(); 
    ordeness.add(detalle); 
    MyTableAdapter adapter=new MyTableAdapter(getActivity(),R.layout.list_item_table,ordeness); 
    list_calllog=(ListView)view.findViewById(R.id.tableArticulosView); 
    list_calllog.setAdapter(adapter); 
    return view; 
} 



public static TabLectura newInstance(int sectionNumber) { 
    TabLectura fragment = new TabLectura(); 
    Bundle args = new Bundle(); 
    args.putInt(ARG_SECTION_NUMBER, sectionNumber); 
    fragment.setArguments(args); 
    return fragment; 
} 

@Override 
public void onClick(View v) { 

} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    if (requestCode == 0) { 
     if (resultCode == getActivity().RESULT_OK) { 

      String contents = intent.getStringExtra("SCAN_RESULT"); 
      String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); 

      Toast.makeText(getActivity(),"SCAN_RESULT --- >>> " + contents , 
        Toast.LENGTH_LONG).show(); 
      // Handle successful scan 

     } else if (resultCode == getActivity().RESULT_CANCELED) { 
      Toast.makeText(getActivity(),"Error" , 
        Toast.LENGTH_LONG).show(); 
     } 
    } 
} 

class MyTableAdapter extends ArrayAdapter<ClassOrdenDetalle> { 

    Context context; 
    int layoutResourceId; 
    ArrayList<ClassOrdenDetalle> data = null; 

    public MyTableAdapter(Context mContext, int layoutResourceId, ArrayList<ClassOrdenDetalle> data) { 

     super(mContext, layoutResourceId, data); 

     this.layoutResourceId = layoutResourceId; 
     this.context = mContext; 
     this.data = data; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 


     LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     view=inflater.inflate(layoutResourceId, parent,false); 
     ClassOrdenDetalle item = data.get(position); 
     Holder holder=new Holder(); 
     holder.text_cantidad=(TextView)view.findViewById(R.id.txtcantidad); 
     holder.text_codigo=(TextView)view.findViewById(R.id.txtarticulo); 
     holder.text_codigo.setText(item.getCod_articulo()); 
     holder.text_cantidad.setText(item.getCantidad()+""); 
     return view; 
    } 

    public class Holder 
    { 
     TextView text_codigo; 
     TextView text_cantidad; 
    } 

}}

Dies ist der Zeilenfehler

holder.text_codigo.setText(item.getCod_articulo());

Weil holder.text_codigonull ist.

Vielen Dank im Voraus für Hilfe und Entschuldigung für schlechte Einrückung (nur in stackoverflow) ich bin neu zum Erstellen von Post.

Es sieht aus wie Sie für 'article_code' und' article_count' im 'getView()' Methode (statt 'txtcantidad' und' txtarticulo') suchen sollte, wie die Textviews sind Sie haben im Layout definiert, dass sich jede Zeile im ListView aufbläst. –

'TabLectura.java: 120' welche Zeile 120 von TabLectura.java? –

Wow, ich habe das nicht überprüft danke ich wurde verrückt !!! –

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 

    View view = convertView; 
    Holder holder; 
    if (view == null) { 
     LayoutInflater inflater= LayoutInflater.from(parent.getContext()); 
     view = inflater.inflate(layoutResourceId, parent, false); 

     holder = new Holder(); 
     holder.text_cantidad=(TextView) view.findViewById(R.id.article_count); 
     holder.text_codigo=(TextView) view.findViewById(R.id.article_code); 

     view.setTag(holder); 
    } else { 
     holder = (Holder) view.getTag(); 
    } 


    ClassOrdenDetalle item = data.get(position); 
    holder.text_codigo.setText(item.getCod_articulo()); 
    holder.text_cantidad.setText(item.getCantidad()+""); 

    return view; 
}

Wie ich in einer anderen Antwort den gleichen Fehler sagte, ConvertView hat MainActivity Wert ist es das ok? –

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 

    Context context = activity.getApplicationContext(); 
    if (convertView == null) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = inflater.inflate(layoutResourceId, null); 
    } 

    ClassOrdenDetalle item = data.get(position); 
    Holder holder=new Holder(); 
    holder.text_cantidad=(TextView)convertView.findViewById(R.id.txtcantidad); 
    holder.text_codigo=(TextView)convertView.findViewById(R.id.txtarticulo); 
    holder.text_codigo.setText(item.getCod_articulo()); 
    holder.text_cantidad.setText(item.getCantidad()+""); 
    return view; 
}
