RecyclerView显示的TextView在顶端 [英] RecyclerView Display TextView At Top

问题描述

我使用RecyclerView与CardView显示卡不同的文字，看起来像这样

I am using RecyclerView with CardView to display different text in cards that looks like this

但我想在顶部有一个文本视图显示只有一个这样的时间

But I want a Text View at the top that displays only one time like this

我应该做一个独立布局的TextView并调用它在相同的活动？我认为，不推荐

Should I make a separate layout with TextView and call it in same Activity? I think that's not recommended

推荐答案

你应该尝试的适配器内部的getItemType

you should try the getItemType inside the adapter

private static final int TYPE_HEADER = 0;
private static final int TYPE_CELL = 1;

@Override
public int getItemViewType(int position) {
    if (position == 0)
        return TYPE_HEADER;
    else
        return TYPE_CELL;
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View convertView;
    switch (viewType) {
        case TYPE_HEADER:
            convertView = LayoutInflater.from(context).inflate(R.layout.myTextView, parent, false);
            return new MyTextViewViewHolder(convertView);
        case TYPE_CELL:
            convertView = LayoutInflater.from(context).inflate(R.layout.myCell, parent, false);
            return new CellViewHolder(convertView);
    }
    return null;
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    switch (getItemViewType(position)) {
        case TYPE_HEADER:
            ((MyTextViewViewHolder) holder) ...
            break;
        case TYPE_CELL:
            ((CellViewHolder) holder) ...
            break;
    }
}
