Complex ListView example with complex data and complex layout of each row?
提问by Eno
Im pulling a list of product objects from a database call and I want to build a ListView of the data in my activity with a non-scrolling header and footer. Each row will consist of a product thumbnail, some data and a button arranged horizontally. I understand that using the ListView I can inflate each row using a separate layout.
我从数据库调用中提取了一个产品对象列表，我想在我的活动中构建一个带有非滚动页眉和页脚的数据的 ListView。每行将包含一个产品缩略图、一些数据和一个水平排列的按钮。我知道使用 ListView 我可以使用单独的布局来增加每一行。
Most of the examples Ive seen using ListView just show a simple array of strings that fill the whole view of the activity, but most real-world examples will be more complex and I can't find any good examples that explain how all these pieces fit together.
我见过的大多数使用 ListView 的示例只显示了一个简单的字符串数组，它们填充了整个活动的视图，但大多数现实世界的示例会更复杂，我找不到任何好的示例来解释所有这些部分是如何适合的一起。
Does anyone have any pointers to sample code with a good explanation ?
有没有人有任何指向示例代码的指针并有很好的解释？

private static class CustomCursorAdapter extends CursorAdapter {
protected ListView mListView;
protected static class RowViewHolder {
public TextView mTitle;
public TextView mText;
}
public CustomCursorAdapter(Activity activity) {
super();
mListView = activity.getListView();
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
// do what you need to do
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View view = View.inflate(context, R.layout.row_layout, null);
RowViewHolder holder = new RowViewHolder();
holder.mTitle = (TextView) view.findViewById(R.id.Title);
holder.mText = (TextView) view.findViewById(R.id.Text);
holder.mTitle.setOnClickListener(mOnTitleClickListener);
holder.mText.setOnClickListener(mOnTextClickListener);
view.setTag(holder);
return view;
}

The easiest way to have a complex row in a ListView is via a SimpleAdapter. There are a number of examples around for that.
在 ListView 中拥有复杂行的最简单方法是通过 SimpleAdapter。有很多这样的例子。
To force the ListView to fill the remaining portion of the screen, set the properties as follows:
要强制 ListView 填充屏幕的剩余部分，请按如下方式设置属性：
Use a LinearLayout.
使用线性布局。
On the list view:
在列表视图中：
android:layout_height="fill_parent",
android:height="0dp",
android:layout_weight="1"
On all other widgets:
在所有其他小部件上：
android:layout_height="wrap_content"
Do not set a height or layout_weight
不要设置高度或 layout_weight
