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:

不要紧,什么是我的DrawerLayout,但如果它layout_height还是layout_width被设置为硬编码的一些其他的东西,它会抛出此运行时异常.
我试图在图形布局工具中渲染输出时看到很多关于此错误的报告,但在运行时错误中找不到任何报告.
我有最新的支持库,刚刚更新到版本 21.0.2
如果可能的话,我想避免硬编码我的身高和宽度.
文件的开头看起来像这样.这样,它就会粉碎.
