Question

我有一个包含自定义行的自定义适配器。在这些自定义行中，我有一个imageview，我必须根据某些东西调整其图像资源。没关系。但是当在第一行中更改此图像视图图像资源时，它会影响在转换视图之后的行不是空的＆＃39;。在我第四排后的情况。我知道它从convertview引用并快速构建，但我怎样才能克服它？（holder.image3）

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.image3 = (ImageButton) convertView.findViewById(R.id.button7);
            holder.tv3 = (TextView) convertView.findViewById(R.id.textView4);
            holder.tv4 = (TextView) convertView.findViewById(R.id.textView8);
            holder.buton1 = (ImageButton) convertView.findViewById(R.id.button7);
            holder.buton2 = (ImageButton) convertView.findViewById(R.id.button8);
            holder.buton3 = (ImageButton) convertView.findViewById(R.id.imageButton7);
            Log.i("tago", "tagtagatagtagtagatg");
        }
        if (!kanal.official) {
            convertView = lala.inflate(R.layout.normalkanal, null);
            holder.image1 = (ImageView) convertView.findViewById(R.id.imageView5);
            holder.tv1 = (TextView) convertView.findViewById(R.id.textView4);
            holder.tv2 = (TextView) convertView.findViewById(R.id.textView8);
            Log.i("tago", "tagtagtag");
        }

        convertView.setTag(holder);
    }else{
        holder = (KanalHolder)convertView.getTag();
    }
        if(kanal.official){
            Drawable a = ContextCompat.getDrawable(context , R.drawable.taylanprof);
            holder.image2.setBackground(a);

            holder.image2.setOnClickListener(new View.OnClickListener() {

                    kanaladi = channelbaba.get(position).getKanaladi();
                    Log.i("tago", kanaladi);
                    kEE = new KanalaElemanEkle();

我只想到解决方案，对不起快速提问。对于新手来说，这需要重新安排：

if(channelbaba.get(position).getLikedurumu()== 1){
                holder.image3.setImageResource(R.mipmap.heartson);
                Log.i("tago" , "likedurumu1");
            }else{
                holder.image3.setImageResource(R.mipmap.heartsonn);
                Log.i("tago", "likedurumu2");
            }
            final ImageButton image1 = holder.image3;
            holder.image3.setOnClickListener(new View.OnClickListener() {
                public void onClick(View view) {
                    channelbaba.get(pozisyon).setLikedurumu(1);
                    image1.setImageResource(R.mipmap.heartson);
                    image1.setClickable(false);
                    Log.i("tago" , "butona tıklanıldı");
                    String channelid = channelbaba.get(pozisyon).getId();
                    Log.i("tago" , "channel id= " + channelid);
                    officialkanalilikela(channelbaba.get(pozisyon).getId());
                }
            });
