我有很多物品的recyclerview。这是我的应用程序的屏幕快照,显示了recyclerview的第一项。 pict of my page
但是当我更改第五项的选择时,第一项的选择也正在更改。知道为什么会这样吗?那我该怎么办?
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

答案 0 :(得分:0)
解决了将其添加到我的java类中的问题:
MyrecyclerView.setItemViewCacheSize(100);
