java - 如何从位置适配器RecyclerView获取值

Question

我有 2 个数据项，其中数据具有不同的 id。当我单击单选按钮时，然后按位置获取 id。

示例:我有 2 个数据项，第一个 id 是 57，第二个 id 是 59。当我单击第一个数据时，它必须获得值 57，或者当我单击第二个数据时，它必须获得值共 59 条。

private String convertAddressID;
private int previousSelected = -1;
private boolean isRadioChecked;

@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {
    ModelGetAddress adapterAddress = modelGetAddressList.get(position);

    convertAddressID = String.valueOf(adapterAddress.getId());
}

public class ViewHolder extends RecyclerView.ViewHolder {
    private RadioButton radioButton;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);

        radioButton = itemView.findViewById(R.id.radioButton);

        radioButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                previousSelected = getAdapterPosition();
                notifyItemRangeChanged(0, modelGetAddressList.size());

                Toast.makeText(getContext, convertAddressID, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

Answer 1

@覆盖 public void onBindViewHolder(@NonNull 最终 ViewHolder 持有者，最终 int 位置) { ModelGetAddress适配器地址 = modelGetAddressList.get(position);

    convertAddressID = String.valueOf(adapterAddress.getId());
}

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    private RadioButton radioButton;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);

        radioButton = itemView.findViewById(R.id.radioButton);
        itemView.setOnClickListener(this);


    }

    @Override
    public void onClick(View view) {
        int position=getAdapterPosition();
        Toast.makeText(conext, ""+modelGetAddressList.get(position).getId(), Toast.LENGTH_SHORT).show();

    }
}
