Android BaseAdapter Fragmanı

Question

Bu kod derlenemiyor ve çalıştırılamıyor. lv.setAdapter(new VcAdapter (this)); numaralı telefondan sorun yaşanıyor. (this)'u geçmemeye çalışırsam, kod derleme işlemi tamamlanır, ancak içeriğin listview olması gerektiğini belirten bir hatayla karşılaşılması gerekir.

Answer 1

Değişim

lv.setAdapter(new VcAdapter (this)); 

lv.setAdapter(new VcAdapter(getActivity())); 

için Sen aktivite bağlamı geçmeleri gerekiyor.

getActivity()

geri bu fragman ilişkilendirilmiş olduğu Etkinlik

.

Answer 2

de (yeni VcAdapter (getActivity())) lv.setAdapter ile bu

@Override 
    public long getItemId(int i) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

için

@Override 
    public long getItemId(int i) { 
     // TODO Auto-generated method stub 
     return i; 
    }
