当我在我的 ListActivity 上使用 Robolectric 2.2 运行 JUnit 测试时，我收到一个 InflateException，指出 ListView 未实现。我该如何解决这个问题？我一直在调查使用 .shadowOf() 的方法，但我不确定该怎么做。
这是堆栈跟踪:

这是我的 activity_main.xml:
< ListView
android:id="@+id/android:list"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:fastScrollEnabled="true">
< TextView
android:id="@+id/android:empty"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
这里是加载activity_main.xml的onCreate()方法:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListAdapter = new ArrayAdapter(this, R.layout.route_item, R.id.list_item);
setListAdapter(mListAdapter);
showProgDialog(this, "加载路线...");
新的 GetRoutesTask().execute("http://"+ getString(R.string.la_metro_query_host)
+ getString(R.string.la_metro_route_query));
}
最佳答案
失败的根本原因是这样的:
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。
关于android - 如何使用 Robolectric 2.2 测试 ListView？它说 android.widget.ListView 还没有实现，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20584985/
