java - 一些 Recyclerview 项目相互影响

Question

我有很多项目的回收 View 。这是我的应用程序的屏幕截图，显示了我的回收 View 的第一项。 pict of my page

但是当我更改第五项的选择时，第一项的选择也会更改。知道为什么会发生这种情况吗？我该怎么办？

这是我的适配器:

public class SkoringAdapter extends RecyclerView.Adapter<SkoringAdapter.SkoringViewHolder>{
private List<Skoring> skoringList;
private Context context;
public SkoringAdapter(final Context context) {
    this.skoringList = new ArrayList<>();
    this.context = context;
}
public void setSkoringList(List<Skoring> skoringList){
    this.skoringList.clear();
    this.skoringList.addAll(skoringList);
    notifyDataSetChanged();
}
static class SkoringViewHolder extends RecyclerView.ViewHolder{
    Context context;
    TextView tvSoal, tvKe, tvTotal, tvProses;
    RadioGroup rgPilihan;
    RadioButton rb1, rb2, rb3, rb4, rb5, rb6;
    SkoringViewHolder(View itemView, final Context context) {
        super(itemView);
        this.context = context;
        tvSoal = itemView.findViewById(R.id.tvSoal);
        ...etc
    }
}
@NonNull
@Override
public SkoringViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_skoring, parent, false);
    return new SkoringViewHolder(itemView,context);
}
@Override
public void onBindViewHolder(@NonNull final SkoringViewHolder holder, final int position) {
    final Skoring tg = skoringList.get(position);
    holder.tvSoal.setText(tg.getSoal());
    holder.tvKe.setText(Integer.toString(position + 1));
    holder.tvTotal.setText(Integer.toString(skoringList.size()));
    holder.rgPilihan.setVisibility(View.GONE);
    holder.rb1.setVisibility(View.GONE);
    holder.rb2.setVisibility(View.GONE);
    holder.rb3.setVisibility(View.GONE);
    holder.rb4.setVisibility(View.GONE);
    holder.rb5.setVisibility(View.GONE);
    holder.rb6.setVisibility(View.GONE);
    String[] kunci = tg.getKunci().split("`");
    String[] pilihan = new String[kunci.length];
    String[] isi = new String[kunci.length];
    String[] skor = new String[kunci.length];
    for (int i=0; i<kunci.length; i++){
        String[] pisah = kunci[i].split("~");
        if(pisah.length == 3){
            pilihan[i] = pisah[0]; isi[i] = pisah[1]; skor[i] = pisah[2];
        }
    }
    holder.rgPilihan.setVisibility(View.VISIBLE);
    if(kunci.length > 0){
        holder.rb1.setText(isi[0]);
        holder.rb1.setVisibility(View.VISIBLE);
        if(kunci.length > 1){
            holder.rb2.setText(isi[1]);
            holder.rb2.setVisibility(View.VISIBLE);
            if(kunci.length > 2){
                holder.rb3.setText(isi[2]);
                holder.rb3.setVisibility(View.VISIBLE);
                if(kunci.length > 3){
                    holder.rb4.setText(isi[3]);
                    holder.rb4.setVisibility(View.VISIBLE);
                    if(kunci.length > 4){
                        holder.rb5.setText(isi[4]);
                        holder.rb5.setVisibility(View.VISIBLE);
                        if(kunci.length > 5){
                            holder.rb6.setText(isi[5]);
                            holder.rb6.setVisibility(View.VISIBLE);
                        }}}}}}}}

这是我的 item_skoring.xml

Answer 1

通过在我的 java 类中添加此解决方案:

MyrecyclerView.setItemViewCacheSize(100);
