整合Android的其它的小部件「面板」爲

Question

我遇到一個ClassCastException試圖將面板元件從android-misc-widgets整合時的Android項目。

我抄org.miscwidgets.widget和org.miscwidgets.interpolator包到我的項目和我有麻煩觀看面板中的圖形佈局顯示。該XML看起來是這樣的 -

<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>... 

堆棧跟蹤爲：

只是想實現一個自上而下的android系統中滑動抽屜。

有人可以幫我找出我做錯了什麼？

Answer 1

在開幕LinearLayout標記線 -

xmlns:panel="org.miscwidgets.widget"

應該

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

希望這可以幫助別人。
