我定义的扩展了的LinearLayout的功能的自定义的ViewGroup：

I've defined a custom ViewGroup that extends the functionality of a LinearLayout:

public class TestLayout extends LinearLayout {

    public TestLayout(Context context, AttributeSet attrs) {
        super(context, attrs);

        LayoutInflater inflater = (LayoutInflater)context.getSystemService
                  (Context.LAYOUT_INFLATER_SERVICE);

        inflater.inflate(R.layout.testlayout, this, true);
    }

}

布局它膨胀（ testlayout.xml ）看起来是这样的：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:gravity="center">

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"/>

</LinearLayout>

终于我现在在用这个自定义组件我的 main.xml中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <my.test.namespace.TestLayout
        android:id="@+id/testLayout1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
    </my.test.namespace.TestLayout>

</LinearLayout>

在看我在布局编辑器main.xml中，日食引发错误：的 my.test.namespace.TestLayout失败的实例。的

When viewing my main.xml in the layout editor, eclipse throws an error: my.test.namespace.TestLayout failed to instantiate.

和堆栈跟踪：

    at android.view.LayoutInflater.inflate(LayoutInflater.java:407)

0x7F030001 指向R.java布局xml文件。我试图清理我的项目，但什么也没做。我使用的LayoutInflater错了，或者是怎么回事呢？

0x7F030001 points to the layout xml file in R.java. I tried cleaning my project, but that did nothing. Am I using the LayoutInflater wrong, or what is going on here?
