如何创建作为新Activity的拉出菜单。
是否可以像在Google的内置便携式摄像机应用程序中那样将其拉出并启动新的活动？
是否支持按钮拉出？如果没有，那怎么办？
最佳答案
请参阅更新2以获取最佳解决方案！
我想我也有同样的问题。为了更好地理解，我在图片中对此进行了描述。我希望你们能为Namratha和我提供一些帮助...
（哦，我刚刚注意到，ImageUploader弄乱了我在图片中的文字。它应该说：“我想在我的应用程序中建立一个下拉菜单。它应该像本示例一样工作。”）

感谢Janusz，他告诉了我应该寻找的东西。
由于某种原因，我总是在Eclipse Layout Preview中得到此错误：
java.lang.IllegalArgumentException: The handle attribute is required and must refer to a valid child.

这就是布局xml。我只是删除了可绘制资源指针...

更新2
刚注意到，我有一个better solution。因为SlidingDrawer窗口小部件仅支持从底部到顶部的滑动。我的第一个更新中的错误仍然存在。
