我目前正在Android页面上构建数据库驱动结果列表。我已经读过，你应该用XML来构建你的内容视图，我已经完成了。我的问题是，如果我真的构建了10个空行并随时填充它们，还是应该通过在Java中构建视图来添加行？我稍后可能会添加更多行。创建表格列表，XML或编程
的数据我展示看起来像这样：右侧增加
的控制和减少分配给一个技能点的数量，因此列表/行将不得不启用一些用户控件的类型。

您想使用CursorAdapter和ListView来显示数据。这里是Android文档的一个例子。 Binding Data
这将让你显示的列表与数据库同步（如果事情被添加或删除），如果你需要复杂的布局，可以设计为XML的行您的项目模板。

我认为你只能以编程方式添加行。
