将 android-misc-widget 'Panel' 集成到 Android 项目中

Question

我在尝试从android-misc-widgets 集成面板小部件时遇到ClassCastException。

我已将 org.miscwidgets.widget 和 org.miscwidgets.interpolator 包复制到我的项目中，但无法在图形布局中查看面板显示。 xml 看起来像这样 -

<LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:panel="org.miscwidgets.widget"..

<FrameLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:paddingLeft="37dip"
    android:paddingRight="37dip"
>
    <org.miscwidgets.widget.Panel
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:id="@+id/topPanel" 
        android:paddingBottom="4dip"
        panel:handle="@+id/panelHandle"
        panel:content="@+id/panelContent"
        panel:position="top"
        panel:animationDuration="1000"
        panel:linearFlying="true"
        panel:openedHandle="@drawable/top_switcher_expanded_background"
        panel:closedHandle="@drawable/top_switcher_collapsed_background"

    >
        <Button
            android:id="@+id/panelHandle" 
            android:layout_width="fill_parent" 
            android:layout_height="33dip" 
        />
        <LinearLayout
            android:id="@+id/panelContent" 
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
        >
            <CheckBox
                android:layout_width="fill_parent" 
                android:layout_height="60dip" 
                android:gravity="center"
                android:text="top check box"
                android:background="#688"
            />
            <TextView
                android:layout_width="fill_parent" 
                android:layout_height="wrap_content" 
                android:gravity="center"
                android:text="Bounce\nInterpolator"
                android:textSize="16dip"
                android:padding="4dip"
                android:textColor="#eee"
                android:textStyle="bold"
                android:background="#323299"
            />
        </LinearLayout>
    </org.miscwidgets.widget.Panel>
    </FrameLayout>...

堆栈跟踪是：

只是想在android中实现一个自上而下的滑动抽屉。

有人可以帮我弄清楚我做错了什么吗？

Answer 1

开头LinearLayout标签中的那一行——

xmlns:panel="org.miscwidgets.widget"

应该是

xmlns:panel="http://schemas.android.com/apk/res/name.of.the.package.that.contains.java.file.that.uses.this.layout.file"

希望这对某人有所帮助。
