SlidingDrawer ID引发的错误 ava.lang.IllegalArgumentException: The handle attribute is must refer to a

在xml文件中定义如下：

01	<? xml version = "1.0" encoding = "utf-8" ?>

02	< LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"

03	android:orientation = "vertical"

04	android:layout_width = "fill_parent"

05	android:layout_height = "fill_parent"

06

07	< SlidingDrawer

08	android:layout_width = "fill_parent"

09	android:layout_height = "fill_parent"

10	android:id = "@+id/sliding"

11	android:handle = "@+id/name"

12	android:content = "@+id/layout"

13

/>

14	< ImageView

15	android:id = "@+id/name"

20	< LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"

21	android:orientation = "vertical"

22	android:id = "@+id/layout"

23	android:layout_width = "fill_parent"

24	android:layout_height = "fill_parent"

25

26

27	</ LinearLayout >

Activity没做任何修改，运行后出现错误：

02-28 14:18:55.887: ERROR/AndroidRuntime(354): java.lang.RuntimeException: Unable to start activity ComponentInfo{yang.slidingdrawer03/yang.slidingdrawer03.SlidignDrawer03}: java.lang.IllegalArgumentException: The handle attribute
is must refer to an existing child.

不好意思，发漏了，完整代码是这样的，：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<SlidingDrawer

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:id="@+id/sliding"

android:handle="@+id/name"

android:content="@+id/layout"

/>

<ImageView

android:id="@+id/name"

android:src="@drawable/icon"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

/>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:id="@+id/layout"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

</LinearLayout>

</LinearLayout>

还是出现上面的错误，Activity没做修改

ImageView,LinearLayout是SlidingDrawer子控件，引用SlidingDrawer的android:handle，android:content的id。

奇怪的是，我写另一个布局文件

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<SlidingDrawer

android:id="@+id/sd"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:orientation="horizontal"

android:handle="@+id/name"

android:content="@+id/content"

>

<Button

android:id="@+id/name"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:background="@drawable/icon"

/>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/content"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

</LinearLayout>

</SlidingDrawer>

</LinearLayout>

却正常运行

你对比下我上面贴的代码，ImageView和LinearLayout是不是包含在SlidingDrawer里面。(7个月前

已检查出来，第一个SlidingDrawer中，应该是<SlidingDrawer > 而不是<SlidingDrawer/>

你多写了一个命名空间-xmlns

在你的第二个linearlayout中不用再写xmlns！
