如何将拉出式菜单创建为新的Activity。

是否可以在Google的内置摄像机应用程序中提供一个可以拉出的按钮并开始新的活动？

按钮是否支持拔出？如果没有，那会是什么？

我想我有同样的问题。为了更好地理解，我在这里用图片描述了它。我希望你们能为Namratha和我提供一些帮助......

（哦，我刚注意到，ImageUploader搞砸了我在图片中的写作。它应该说“我想在我的应用程序中构建一个下拉菜单。它应该像这个例子一样工作。”）

感谢Janusz，他告诉我应该寻找什么。

出于某种原因，我总是在Eclipse布局预览中遇到此错误：

java.lang.IllegalArgumentException: The handle attribute is required and must refer to a valid child.

那是布局xml。我刚删除了可绘制的资源指针...... 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/LinearLayoutTesting"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  android:gravity="bottom">
  <SlidingDrawer
    android:layout_width="wrap_content"
    android:id="@+id/SlidingDrawer"
    android:handle="@+id/slideHandleButton"
    android:content="@+id/contentLayout"
    android:padding="10dip"
    android:layout_height="250dip">
    <Button

      <Button

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

  </SlidingDrawer>

</LinearLayout>

更新2

注意到，我有一个better solution。因为SlidingDrawer Widget仅支持从底部到顶部滑动。我第一次更新的错误仍然存​​在。

用于此类布局的窗口小部件是Sliding Drawer。您只需要为句柄定义一个布局，为抽屉的内容定义一个布局。现在你可以听一些事件，比如抽屉被打开，滚动或关闭。
