【问题描述】：

RecyclerView 项目不可见我正在使用字符串数组名称项测试并将其传递给字符串数组列表，我之前使用过相同的想法并且工作正常

    listItemsTest = new ArrayList<>(Arrays.asList(itemsTest));
    recyclerView = findViewById(R.id.RecycleViewTest);
    recycleViewAdapterTest = new RecycleViewAdapterTest(this,listItemsTest);
    recyclerView.setAdapter(recycleViewAdapterTest);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));

我的适配器

public class RecycleViewAdapterTest extends 
RecyclerView.Adapter<RecycleViewAdapterTest.MyViewHolder> {

private ArrayList<String> ListTest;
Context context;

public RecycleViewAdapterTest(Context context, ArrayList<String> listTest) {

    this.ListTest = listTest;
    this.context = context;
}

@NonNull
@Override
public RecycleViewAdapterTest.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.test_list,parent,false);
    MyViewHolder holder = new MyViewHolder(view);

    return holder;
}

@Override
public void onBindViewHolder(@NonNull RecycleViewAdapterTest.MyViewHolder holder, int position) {

}

@Override
public int getItemCount() {
    return ListTest.size();
}

public static class MyViewHolder extends RecyclerView.ViewHolder {

    LinearLayout linearLayout;
    TextView textView;

    public MyViewHolder(@NonNull View itemView) {
        super(itemView);
        linearLayout = itemView.findViewById(R.id.LLTest);
        textView = itemView.findViewById(R.id.textViewTest);

    }
}

【解决方案1】：

@Override
public void onBindViewHolder(@NonNull RecycleViewAdapterTest.MyViewHolder holder, int position) {
    String value = this.ListTest.get(position);
    holder.textView.setText(value);// Try to make the textView public
}

【解决方案2】：

因为您需要在 OnBindViewHolder 中为 viewholder 的 textview 设置列表值。 :(
