Fragment Absturz durch Set Adapter mit getActivity

Question

Ich verstehe nicht etwas über Fragmente. Wenn ich einen Adapter mit getActivity() oder getContext(). GetApplicationContext() setze und ich starte die App, stürzt die App ab. mein Testprojekt (ohne Fragmente mit dem gleichen Code) funktioniert.

Fragment:

public class RecipesFragment extends Fragment { 

public RecipesFragment() { 
    // Required empty public constructor 

} 

ArrayList<RecipesData> recipesDatas; 
static RecipesAdapter adapter; 
ListView listView; 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    View view; 
    view = inflater.inflate(R.layout.fragment_recipes, container, false); 


    recipesDatas = new ArrayList<>(); 
    listView = (ListView) view.findViewById(R.id.list_recipes); 

    recipesDatas.add(new RecipesData("test","test","test",30)); 
    recipesDatas.add(new RecipesData("test","test","test",30)); 
    recipesDatas.add(new RecipesData("test","test","test",30)); 
    recipesDatas.add(new RecipesData("test","test","test",30)); 
    recipesDatas.add(new RecipesData("test","test","test",30)); 

    adapter = new RecipesAdapter(recipesDatas, getActivity()) ; 

    listView.setAdapter(adapter); 

    return view; 
} 

} 

CustomAdapter:

public class RecipesAdapter extends ArrayAdapter<RecipesData> { 

private ArrayList<RecipesData> dataSet; 
Context mContext; 


private static class ViewHolder { 
    TextView txtName; 
    TextView txtType; 
    TextView txtCarbo; 
    TextView txtTime; 
} 


public RecipesAdapter(ArrayList<RecipesData> data, Context context) { 
    super(context, R.layout.row_recipes, data); 
    this.dataSet = data; 
    this.mContext = context; 
} 


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

    RecipesData recipesData = getItem(position); 

    ViewHolder viewHolder; 

    final View result; 

    if (connvertView == null) { 

     viewHolder = new ViewHolder(); 
     LayoutInflater inflater = LayoutInflater.from(getContext()); 
     connvertView = inflater.inflate(R.layout.row_recipes,parent,false); 
     viewHolder.txtName = (TextView) connvertView.findViewById(R.id.name); 
     viewHolder.txtType = (TextView) connvertView.findViewById(R.id.type); 
     viewHolder.txtCarbo = (TextView) connvertView.findViewById(R.id.carbo); 
     viewHolder.txtTime = (TextView) connvertView.findViewById(R.id.time); 

     result = connvertView; 

     connvertView.setTag(viewHolder); 
    }else { 
     viewHolder = (ViewHolder) connvertView.getTag(); 
     result = connvertView; 
    } 

    viewHolder.txtName.setText(recipesData.getName()); 
    viewHolder.txtType.setText(recipesData.getType()); 
    viewHolder.txtCarbo.setText(recipesData.getCarbo()); 
    viewHolder.txtTime.setText(recipesData.getTime()); 

    return connvertView; 
} 


}

Answer 1

Problem ist, mit

viewHolder.txtName.setText(recipesData.getName()); 
viewHolder.txtType.setText(recipesData.getType()); 
viewHolder.txtCarbo.setText(recipesData.getCarbo()); 
viewHolder.txtTime.setText(recipesData.getTime()); 

setTextint als resource id nehmen kann, so dass, wenn einer Ihrer get Methode int Rückkehr Ihr es mit String.valueOf(i)

tun sollten
