Listview hatası: "İçeriğinizin id özniteliği" android.R.id.list "olan bir ListView olmalıdır"

Question

Logcat'ta bir hata alıyorum "İçeriğinizin kimliği özniteliği 'olan bir ListView olmalıdır. R.id.list '". Kodumu derler ve çalışır, ancak liste görüntüleme etkinliğimi başlattığımda güç kapanır. Birçok benzer soruyu kontrol ettim, genel bir sorun gibi görünüyor ama hala kodumu düzeltemiyorum.

Beyanı:

private ListView lv; 
    Context mContext; 
    List mList; 
    String[] testcontacts; 

    MessageView aa = null; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.firstlist); 
     testcontacts = getResources() 
       .getStringArray(R.array.testcontacts_array); 

     aa = new MessageView(); 
     lv = getListView();/*(ListView) lv.findViewById(R.id.list); Had to comment out, it cannot find list*/ 
     lv.setAdapter(aa); 
     lv.setTextFilterEnabled(true); 

     lv.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
       // When clicked, show a toast with the TextView text 
       Toast.makeText(getApplicationContext(), 
         ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 
class MessageView extends ArrayAdapter<String> { 
     MessageView() { 
      super(FirstLoginActivity.this, android.R.layout.activity_list_item, 
        testcontacts); 
      // TODO Auto-generated constructor stub 
     } 

     public View getView(int position, View convertview, ViewGroup parent) { 
      Log.d("Ebz", "inside getView method"); 
      ViewHolder holder; 
      View v = convertview; 
      if (v == null) { 
       Log.d("Ebz", "if v == null"); 
       LayoutInflater inflater = getLayoutInflater(); 
       v = inflater.inflate(R.layout.list_items, null); 
       holder = new ViewHolder(); 
       holder.firstLine = (TextView) v.findViewById(R.id.firstLine); 
       holder.secondLine = (TextView) v.findViewById(R.id.secondLine); 
       holder.icon1 = (ImageView) v.findViewById(R.id.icon1); 
       holder.icon2 = (ImageView) v.findViewById(R.id.icon2); 
       v.setTag(holder); 
      } else { 
       holder = (ViewHolder) v.getTag(); 
      } 
      holder.firstLine.setText(testcontacts[position]); 
      holder.secondLine.setText(testcontacts[position]); 
      holder.icon1.setImageBitmap(null); 
      holder.icon2.setImageBitmap(null); 
      // call the images directly? 
      return v; 
     } 

     class ViewHolder { 
      TextView firstLine; 
      TextView secondLine; 
      ImageView icon1; 
      ImageView icon2; 

     } 
    } 
}

Answer 1

Muhtemelen ListActivity kullanıyor. Sende

için id yerine firstlist.xml: id/listeye:

<ListView 
    android:id="@android:id/list" 
... 

ListActivity @android olan xml sen id R.android.id.list arar.
