问题描述
我创建了一个自定义对话框类
i have created a custom dialog class
public class NewPost extends Dialog
{
// functionality
}
现在我的要求是在其中创建列表视图.我知道我们可以在其中创建文本框、按钮、下拉列表.
now my requirement is to create listview inside it. i know we can create textboxes,buttons,dropdown list inside it.
但是为了创建列表视图，我们应该从 listActivity 类继承我们的类
but in order to create list view we should inherit our class from listActivity class
您的建议是否可能，如果是，那么如何使用任何接口或什么来实现这一点?
what you suggest is it possible or not if yes then how to achieve this using any interface or what?
推荐答案
您真的不必为了使用列表视图而扩展 listActivity.
You don't really have to extend listActivity in order to use listviews.
扩展 listActivity 将免费为您提供一些功能，例如 getListView() (如果我没记错方法名称)，但也可以这样做手动使用 findViewById() 就像任何其他视图一样.
Extending listActivity will give you some functionality for free, such as getListView() (if I recall the method name correctly), but that can just as well be done manually with findViewById() just as any other view.
