在Android的ListView的多种细胞类型 [英] Multiple Cell Types in Android ListView

问题描述

我想要做的是显示一些数据一本书像标题，作者和封面，而这些数据的下方，有包含可点击的章节列表一个ListView。

What I'm trying to do is to show some data for a book like Title, Author, and a Cover, and beneath these data, to have a ListView containing a list of clickable chapters.

我想过将有不同类型的细胞，其中第一个将包含数据的一个ListView，和他们的其余部分将是包含章节简单细胞的一种方式。 ListView控件绑定到实现NewView的（...）和bindView（...）方法，我不知道如何才能返回基于细胞的位置不同类型的细胞自定义定制CursorAdapter的。

One way I've thought would be to have a ListView with different type of cells, where the first would contain the data, and the rest of them would be simple cells containing the chapters. The ListView binds to a custom CursorAdapter that implements the newView(...) and bindView(...) methods, which I don't know how to customise in order to return different types of cells based on the cell's position.

@Override
public void bindView(View view, Context context, Cursor cursor) {

    TextView title = (TextView) view.findViewById(R.id.title);
    title.setText(cursor.getString(cursor.getColumnIndex(Constants.TITLE)));
    ..
}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View v = inflater.inflate(R.layout.bookcell, parent, false);
    bindView(v, context, cursor);
    return v;
}

我应该怎样做呢？

How should I do that?

谢谢！

推荐答案

您可以做到这一点：

1. 重写 getViewTypeCount（）并返回不同的行布局的数量


2. 重写 getItemViewType（）并返回该行布局的从零开始的索引被用于给定位置


3. 调整 NewView的（）和 bindView（）来使用基于位置的右排型（例如， NewView的（）膨胀根据位置）
不同的行布局

1. Overriding getViewTypeCount() and returning the number of distinct row layouts
2. Overriding getItemViewType() and returning a 0-based index of the row layout to be used for a given position
3. Adjusting newView() and bindView() to use the right row type based on the position (e.g., newView() inflates different row layouts based on position)

或者，你可以尝试从组装件适配器，使用像我 MergeAdapter 。

Or, you can try assembling your adapter from pieces, using something like my MergeAdapter.
