如何创建拉出菜单作为新活动

发布于 2024-09-09 03:50:38 字数 131 浏览 9 评论 0原文

如何创建拉出菜单作为新的Activity。

是否有可能有一个按钮，您可以像 Google 内置的摄像机应用程序一样拉出一个按钮，然后启动一个新的活动？

按钮支架是否拉出？如果不是，那是什么？

原文

How do you create a pull out menu as a new Activity.

Is it possible to have a button that you can pull out as in the Google's built in camcorder app and have that start a new activity?

Does a button support pull out? If not, what does?

请参阅更新 2 以获得最佳解决方案！

我想我也有同样的问题。为了更好地理解，我用图片来描述它。我希望你们能为 Namratha 和我提供一些帮助...

（哦，我刚刚注意到， ImageUploader 搞乱了我在图片中的书写。它应该说“我想在我的应用程序中构建一个下拉菜单。它应该像这个示例一样工作。”）

更新

谢谢Janusz，他告诉我应该寻找什么。

由于某种原因，我总是在 Eclipse 布局预览中收到此错误：

That's the layout xml。我刚刚删除了可绘制资源指针...

        android:text="Content"></Button>
    </LinearLayout>

  </SlidingDrawer>

</LinearLayout>

更新2

刚刚注意到，有一个对我来说更好的解决方案。因为SlidingDrawer Widget只支持从下往上滑动。我第一次更新时出现的错误仍然存​​在。

See Update 2 for best solution!

I guess I have the same problem. For better understanding, I described it here in a picture. I hope u guys can provide Namratha and me some help...

(Oh I just noticed, the ImageUploader messed up my writing in the picture. It shall say "I'd like to build a drop down menu into my app. It should work just like this example.")

Udpate

Thanks to Janusz, who told me what I should look for.

For some reason I always get this error in my Eclipse Layout Preview:

        android:layout_height="wrap_content"
        android:text="Content"></Button>
    </LinearLayout>

  </SlidingDrawer>

</LinearLayout>

Update 2

Just noticed, there is a better solution for me. Because the SlidingDrawer Widget only supports sliding from bottom to the top. The error from my first Update is still existing.

用于这种布局的小部件是 滑动抽屉。您只需为手柄定义​​一种布局，并为抽屉的内容定义一种布局。现在您可以监听一些事件，例如抽屉被打开、滚动或关闭。

The widget used for this kind of Layout is a Sliding Drawer. You just have to define a layout for the handle and one for the content of the drawer. Now you can listen to some events like the drawer was opened, scrolled or closed.
