Question

我有以下适配器，它使用包含一个TextView的CardView项填充RecyclerView。它使用String数组中的数据填充这些TextView。但是，现在我想在我的CardViews中添加另一个TextView并用一个单独的数据阵列填充它，我想知道如何才能最好地实现这一点：

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
private String[] mDataset;

public static class ViewHolder extends RecyclerView.ViewHolder {

    public TextView mTextView;
    public ViewHolder(View itemView) {
        super(itemView);
        mTextView = (TextView)itemView.findViewById(R.id.grade);
    }
}

public RecyclerAdapter(String[] myDataset) {
    mDataset = myDataset;
}

@Override
public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                               int viewType) {

    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.card_item, parent, false);

    ViewHolder vh = new ViewHolder(v);

    return vh;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    holder.mTextView.setText(mDataset[position]);

}

@Override
public int getItemCount() {
    return mDataset.length;
    }
}

所有帮助一如既往地受到赞赏！

只需在CardLayout XML TextView

中添加其他R.layout.card_item或任何其他视图

然后

public TextView mTextView;
public TextView mTextView1;
public TextView mTextView2;
public TextView mTextView3;

 public ViewHolder(View itemView) {
    super(itemView);
    mTextView = (TextView)itemView.findViewById(R.id.grade);
    mTextView1 = (TextView)itemView.findViewById(R.id.grade1);
    mTextView2 = (TextView)itemView.findViewById(R.id.grade2);
    mTextView3 = (TextView)itemView.findViewById(R.id.grade3);
  }

最后将数据设置为所有想要的文本视图

    @Override
 public void onBindViewHolder(ViewHolder holder, int position) {
     holder.mTextView.setText("String");
     holder.mTextView1.setText("String");
     holder.mTextView2.setText("String");
     holder.mTextView3.setText("String");
    }

在RecyclerView中使用多个视图和数据集
