eclipse 使用 SlidingDrawer 的图形布局中的 Eclpse 3.5 和 3.6 中的 ClassCastException

ClassCastException in Eclpse 3.5 and 3.6 when in Graphical Layout with a SlidingDrawer

提问by EraserheadIRL

Has anyone got the Graphical Layout working correctly in either Eclipse 3.5 or 3.6 when using a Sliding Drawer?

当使用滑动抽屉时，有没有人让图形布局在 Eclipse 3.5 或 3.6 中正常工作？

I keep getting the following error in both:

我不断收到以下错误：

error!
ClassCastException: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup Exception details are logged in Window > Show View > Error LogThe following classes could not be found: - SlidingDrawer

错误！
ClassCastException: com.android.layoutlib.bridge.MockView 无法转换为 android.view.ViewGroup 异常详细信息记录在窗口 > 显示视图 > 错误日志中找不到以下类：- SlidingDrawer

I get this error with my code and any example code you can find around:

我的代码和您可以找到的任何示例代码出现此错误：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#8CB69C">

    <SlidingDrawer
        android:id="@+id/drawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:handle="@+id/handle"
        android:content="@+id/content">

    <ImageView
        android:id="@id/drawerhandle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/drawerhandle"/>

    </SlidingDrawer>
</FrameLayout>  

When I run the app on a device it works fine without any problems so it's got to be a problem with either Android SDK 8, Eclipse 3.5 and 3.6 or my workspace, I've know idea yet. If it works fine for others then it's got to be something local.

当我在设备上运行该应用程序时，它运行良好，没有任何问题，因此它一定是 Android SDK 8、Eclipse 3.5 和 3.6 或我的工作区的问题，我已经知道了。如果它对其他人很好，那么它必须是本地的。

I got the same error but it turned out that I had mistaken the custom component class path in the XML file. So, check that SlidingDrawer class is in the same package or - better - fully qualify the class. For example, try:

我遇到了同样的错误，但结果是我弄错了 XML 文件中的自定义组件类路径。因此，请检查 SlidingDrawer 类是否在同一个包中，或者 - 更好地 - 完全限定该类。例如，尝试：

<com.some.class.path.SlidingDrawer android:id="@+id/drawer"

<com.some.class.path.SlidingDrawer android:id="@+id/drawer"

3.2 resolve the issue, there is still a warning "The graphics preview in the layout editor may not be accurate: * Different corner sizes are not supported in Path.addRoundRect" but at the editor is completely usable.

3.2 解决问题，仍然提示“布局编辑器中的图形预览可能不准确：* Path.addRoundRect 中不支持不同的角尺寸”但在编辑器中完全可用。

In all your xmlfiles, use strings as in the @string/command. When I replaced the @string/with a text string I got above error again.

在所有xml文件中，使用@string/命令中的字符串。当我用@string/文本字符串替换时，我再次出现上述错误。

I noobed it up and had a Buttoninside of my SurfaceView. In which case, the exception message is helpful.

我 noobed 并Button在我的SurfaceView. 在这种情况下，异常消息很有帮助。

android.view.*SomeView* cannot be cast to  android.view.ViewGroup

making the Buttona sibling of the SurfaceViewin my layout xml file resolved this issue.

使我的布局 xml 文件中的Button的同级SurfaceView解决了这个问题。

You don't have the layout defined completely

您没有完全定义布局

<SlidingDrawer
    android:id="@+id/drawer"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:handle="@+id/handle"
    android:content="@+id/content">

Notice how the android:handle="@+id/handle"points at "handle", and android:content="@+id/content"points at content, however, you don't have any of those in SlidingDrawer. I guess you should define something like this:

请注意android:handle="@+id/handle"“句柄”处的android:content="@+id/content"点和内容处的点，但是，您在 SlidingDrawer 中没有任何这些点。我想你应该定义这样的东西：

<SlidingDrawer
    android:id="@+id/drawer"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:handle="@+id/handle"
    android:content="@+id/content">

    <Button
        android:id="@+id/slideButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#fff" >
    </Button>

    <LinearLayout
        android:id="@+id/contentLayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#000"
        android:gravity="center"
        android:orientation="vertical"
        android:padding="10dip" >
    </LinearLayout>
</SlidingDrawer>

Yes even i got the same error and after searching for it over the net came to the conlcusion that its the Eclipse ADT plugin issue.

是的，即使我遇到了同样的错误，在网上搜索后得出的结论是它的 Eclipse ADT 插件问题。
