Custom Listview'i fragment içinde kullanımı

İyi günler custom listview oluşturup fragmentte kullanıcam sonra bu fragmenti mainactivity içine çağıracam kodun neresinde hata var sürekli aynı yerde hata veriyor

Kisi.class

`public class Kisi { private String isim; private boolean kadinMi;

public Kisi(String isim, boolean kadinMi) {
    super();
    this.isim = isim;
    this.kadinMi = kadinMi;
}

@Override
public String toString() {
    return isim;
}

public String getIsim() {
    return isim;
}

public void setIsim(String isim) {
    this.isim = isim;
}

public boolean isKadinMi() {
    return kadinMi;
}

public void setKadinMi(boolean kadinMi) {
    this.kadinMi = kadinMi;
}

}`

OzelAdapter.class

public class OzelAdapter extends BaseAdapter { private LayoutInflater mInflater; private List<kisi> mKisiListesi;

public OzelAdapter(Activity activity, List<Kisi> kisiler) {
    //XML'i alıp View'a çevirecek inflater'ı örnekleyelim
    mInflater = (LayoutInflater) activity.getSystemService(
            Context.LAYOUT_INFLATER_SERVICE);
    //gösterilecek listeyi de alalım
    mKisiListesi = kisiler;
}

@Override
public int getCount() {
    return mKisiListesi.size();
}

@Override
public Kisi getItem(int position) {
    //şöyle de olabilir: public Object getItem(int position)
    return mKisiListesi.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

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

    satirView = mInflater.inflate(R.layout.satir_layout, null);
    TextView textView =
            (TextView) satirView.findViewById(R.id.isimsoyisim);
    ImageView imageView =
            (ImageView) satirView.findViewById(R.id.simge);

    Kisi kisi = mKisiListesi.get(position);

    textView.setText(kisi.getIsim());

    return satirView;
}
