Android 使用QuickReturn的自定义适配器中出现ArrayList索引越界异常

首先，我有一个可以正常工作的自定义适配器。然后我为我的listview实现quickreturn。现在适配器类给了我一个越界异常。我尝试更改getCount返回值，但仍然出现错误

我的适配器类：

public class KanalAdapter extends BaseAdapter {

Context context;
String charset;
String query;
String kanaladi;
String veritabani_id;
ArrayList<OfficialKanal> officialKanals;
ArrayList<NormalKanal> normalKanals;
ArrayList<Object> kanallar = new ArrayList();
ArrayList<Kanal> channelbaba;
int OFFICIAL_KANAL = 0;
int NORMAL_KANAL= 1;
LayoutInflater lala;
KanalaElemanEkle kEE;
public KanalAdapter(Context context , ArrayList<OfficialKanal> officiallar , ArrayList<NormalKanal> normaller
        , ArrayList<Kanal> channelbaba){
    this.context = context;
    officialKanals = officiallar;
    normalKanals = normaller;
    this.channelbaba = channelbaba;

    for(int i = 0 ; i < officiallar.size() ; i++){
        kanallar.add(officiallar.get(i));
    }
    for(int i = 0 ; i < normaller.size() ; i++){
        kanallar.add(normaller.get(i));
    }
    Log.i("tago" , "tagtag");
    veritabani_id = SharedIdCek();
    lala = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

private String SharedIdCek() {
    SharedPreferences sp = context.getSharedPreferences("kullaniciverileri", Context.MODE_PRIVATE);
    String veritabani_id = sp.getString("veritabani_id", "default id");
    return veritabani_id;
}

public int getCount() {
    Log.i("tago" , "getCount ="+(channelbaba.size()+1));
    return (channelbaba.size()+1);
}

public Object getItem(int i) {
    Log.i("tago" , "getItem = " + channelbaba.get(i));
    return channelbaba.get(i);
}

public long getItemId(int i) {
    Log.i("tago" , "getItemId =" + i);
    return i;
}

public int getItemViewType(int position) {
    Object item = getItem(position);
    Kanal kanal = (Kanal)item;
    if(kanal.official){
        return OFFICIAL_KANAL;
    }else if(!kanal.official){
        return NORMAL_KANAL;
    }
    return -1;
}

    return 2;

    KanalHolder holder = null;
    final int pozisyon = position;
    Object currentKanal = getItem(position);
    Kanal kanal = (Kanal) currentKanal;
    if(convertView==null) {
        holder = new KanalHolder();
        if (kanal.official) {
            convertView = lala.inflate(R.layout.officialkanal, null);
            holder.image2 = (ImageView) convertView.findViewById(R.id.imageView5);
            holder.tv3 = (TextView) convertView.findViewById(R.id.textView4);
            holder.tv4 = (TextView) convertView.findViewById(R.id.textView8);

        }

        convertView.setTag(holder);
    }else{
        holder = (KanalHolder)convertView.getTag();
    }
        if(kanal.official){

                    context.startActivity(intent);
                }
            });
        }
    return convertView;

我怎样才能解决这个问题

public int getCount() {
 Log.i("tago" , "getCount ="+(channelbaba.size()+1)); 
return (channelbaba.size()+1); 
}

尝试重新键入

kanal.size（）

如果kanal和channelbaba的大小相同，请尝试删除+1
