Application force close, lors de la tentative de définition d'un TextView sur customListAdapter

Je veux définir du texte dans TexView, en fait je stocke le nombre dans la liste de tableau, mais il force toujours la fermeture. donc, j'essaie juste de le régler manuellement, il force quand même. Je n'ai aucune idée pourquoi d'autres textview en mesure de définir, mais amountStr ne peut pas être défini.Application force close, lors de la tentative de définition d'un TextView sur customListAdapter

Merci d'avance pour votre suggestion.

Voici un code:

ActActivity.class

public class ActActivity extends ListActivity { 

    private CustomListAdapter listAdapter; 
    private String[] activities_list; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_list); 

     activities_list = getResources().getStringArray(R.array.Activities_array); 

     listAdapter = new CustomListAdapter(this,R.layout.list_item_choose_activities,activities_list);  

     setListAdapter(listAdapter); 

    } 

    private class CustomListAdapter extends ArrayAdapter<String>{ 

     private String[] items; 
     public CustomListAdapter(Context context, int textViewResourceId, 
       String[] items) { 
      super(context, textViewResourceId, items); 
      this.items = items; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      View v = convertView; 
      if(v == null){ 
       LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       v = vi.inflate(R.layout.list_item_choose_activities, null); 
      } 

      TextView actNameStr = (TextView)v.findViewById(R.id.list_act_txt); 
      ImageView actLogo = (ImageView)v.findViewById(R.id.act_logo); 
      TextView amountStr = (TextView)findViewById(R.id.amount_text); 

      actNameStr.setText(items[position]); 
      // i wanna set text number here, actually i store number in array list but,it always force close. so, i try just set manually though, it still force close. 
      amountStr.setText("5"); 


      //Set icon of activity on each list items 
      switch (position) { 
      case 0: 
       actLogo.setBackgroundResource(R.drawable.a01_ofroad); 
       break; 
      case 1: 
       actLogo.setBackgroundResource(R.drawable.a02_bungeejump); 
       break; 
      case 2: 
       actLogo.setBackgroundResource(R.drawable.a03_art); 
       break; 
         default: 
       actLogo.setBackgroundResource(R.drawable.nologo); 
       break; 
      } 
     return v; 
    } 

    } 
}

TextView amountStr = (TextView)findViewById(R.id.amount_text); vous devez peut-être changer pour: TextView amountStr = (TextView)v.findViewById(R.id.amount_text);

LOL. quel stupide je suis? Mon cerveau + les yeux ont besoin de repos. Merci quand même –

Il vous manque une référence à v dans

TextView amountStr = (TextView) findViewById (R.id.amount_text);

devrait-il pas être

TextView amountStr = (TextView) v.findViewById (R.id.amount_text);
