如何使用Robolectric 2.2测试ListView？它说android.widget.ListView尚未实现

标签： android listview android-listview robolectric

当我在ListActivity上使用Robolectric 2.2运行JUnit测试时，我得到一个InflateException，表明ListView没有实现。我该如何解决这个问题？我一直在调查使用.shadowOf（），但我不知道该怎么做。

这是堆栈跟踪：

        android.view.InflateException: XML file ./res/layout/activity_main.xml line #-1 (sorry, not yet implemented): Error inflating class android.widget.ListView

这是我的activity_main.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/android:list"
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:layout_weight="1"
        android:fastScrollEnabled="true" >
    </ListView>

    <TextView
        android:id="@+id/android:empty"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity" > <ListView android:id="@+id/android:list" android:layout_width="match_parent" android:layout_height="0dip" android:layout_weight="1" android:fastScrollEnabled="true" > </ListView> <TextView android:id="@+id/android:empty" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout>

这是加载activity_main.xml的onCreate（）方法：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mListAdapter = new ArrayAdapter<String>(this, R.layout.route_item, R.id.list_item);
    setListAdapter(mListAdapter);

    showProgDialog(this, "Loading routes...");
    new GetRoutesTask().execute("http://" + getString(R.string.la_metro_query_host)
          + getString(R.string.la_metro_route_query));
}

2 个答案:

答案 0 :(得分：0)

失败的根本原因是：

java.lang.StringIndexOutOfBoundsException: String index out of range: -9

我怀疑Robolectric没有正确解析android:id引用。尝试将ID更改为项目中生成的内容，例如android:id="+id/list"，并查看您的测试是否有效。

答案 1 :(得分：0)

正如Justin Muller评论我原来的问题，还有另一个问题正确地说明了ListView的id应该是

android:id="@android:id/list"
