Android layout 在机器人分光计中，我如何绕过抽屉布局必须用测量方法进行测量，特别是精确误差？

我正在尝试向我的应用程序添加抽屉布局以进行导航，我正在使用Robolectric测试我的应用程序（我在Robolectric 2.1.1和2.1-SNAPSHOT-2.2-20130712.161723-17中都看到了这个问题）

我使用以下xml作为抽屉布局的基础。当我将抽屉布局上的andioid:layout\u width或android:layout\u height设置为“match\u parent”时，我在Robolectric中遇到了错误

<?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>

我已经尝试将这些设置为硬编码值（比如400dp），这就解决了测试中的问题。然而，我很难让宽度和高度与安装在手机上的应用程序的父项匹配。有什么方法可以设置我的机器人装置的宽度和高度吗？或者有没有人遇到过这种情况，并想出了一些其他的解决办法

它似乎与此问题有关：注意，此问题的另一个副作用是设计视图被破坏

经过一番挖掘，我找到了一个解决办法。看来，机器人分子在某种程度上计算错误的度量，这导致了这个问题。在我的例子中，我可以通过扩展抽屉布局并覆盖onMeasure（）来解决这个问题：

---

更新您的支持库jar：

并确保您的项目引用了最新的项目：

---

库的示例路径：[adt bundle windows]\sdk\extras\android\support\v4\android-support-v4.jar

只需在android设备上运行程序即可。它运行得很好。我想这只是Eclipse中的一些问题。

如果您扩展抽屉布局并确保测量规格是正确的。。。如果你愿意试试的话，因为我在同一个问题上，我刚刚找到了你的答案joecks。。。尝试从抽屉布局视图的一部分片段启动意图时遇到此问题。。。快把我逼疯了。。非常感谢你！这在运行时仍然是一个问题，尽管谷歌声称已经在Android支持库第19版（2013年10月）中修复了这一问题。这项技术比我以前的技术好得多。
