I do not know how to determine real size the widget 4x4 in dp. It seems that it can be determined only by knowing the specific device.
我不知道如何在dp中确定小部件4x4的实际大小。似乎只有知道具体的设备才能确定。
You can scroll by fixed number of rows.
您可以按固定的行数滚动。

The only pre 3.0 example with source I know of is the ScrollableContacts project on Google Code. It features a scrollable list in a home screen widget and works from 2.1. However, the widget requires a home replacement - see the project description. The source can be viewed here.
我所知道的唯一一个具有源代码的pre 3.0示例是关于谷歌代码的ScrollableContacts项目。它在主屏幕小部件中提供了一个可滚动列表，可以从2.1开始工作。但是，小部件需要一个家庭替换—请参阅项目描述。源代码可以在这里查看。
