我正在尝试将DrawerLayout添加到我的导航应用程序中,并且我正在使用Robolectric测试我的应用程序(我已经在Robolectric 2.1.1和2.1-SNAPSHOT中看到了这个问题 - 2.2-20130712.161723-17)

我使用以下xml作为抽屉布局的基础.当我将andioid:layout_width或android:layout_height设置为抽屉布局上的"match_parent"时,我在Robolectric中遇到错误.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    <!-- The navigation drawer -->
    <ListView android:id="@+id/left_drawer"
        android:layout_width="250dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="#D8D8D8"
        android:dividerHeight="1dp"
        android:background="#F2F2F2"/>
</android.support.v4.widget.DrawerLayout>

这是我遇到的错误的堆栈跟踪:
