Question

我是Android的新手，我正在使用http://code.google.com/p/android-dateslider/组件，我想将其添加到我的视图中而不是弹出对话框中。

这意味着我将在视图顶部设置对话框滑块，通过滑动它将会显示下面选定日期的其他信息。

有没有办法做到这一点，或者我只能使用对话框表格。（我知道对于datepicker我可以在视图中使用xml声明位置，但我真的很喜欢使用datespinner，因为它非常棒:)）

编辑：//

我通过以下方式通过xml声明尝试了它：

   <com.googlecode.android.widgets.DateSlider.SliderContainer
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/dateSliderContainer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/button1">

        <com.googlecode.android.widgets.DateSlider.ScrollLayout
            style="@style/Scroller"
            app:childWidth="90dp"
            app:labelerClass="com.googlecode.android.widgets.DateSlider.labeler.MonthYearLabeler"
            app:labelerFormat="%tb %tY" >
        </com.googlecode.android.widgets.DateSlider.ScrollLayout>

        <com.googlecode.android.widgets.DateSlider.ScrollLayout
            style="@style/Scroller"
            app:childWidth="45dp"
            app:labelerClass="com.googlecode.android.widgets.DateSlider.labeler.DayDateLabeler"
            app:labelerFormat="%td %ta" >
        </com.googlecode.android.widgets.DateSlider.ScrollLayout>

        <include layout="@layout/dialogbuttons" />
    </com.googlecode.android.widgets.DateSlider.SliderContainer>

当我启动应用程序时，我可以看到日期滑动，但是当我触摸它时，应用程序崩溃：应用程序已经意外停止。抛出此异常：

所以我想应该创建SliderContainer实例......但是在哪里？
