android – 自定义布局通货膨胀与Robolectric中的碎片无法正常工作

在使用LayoutInflater对Fragment中的布局进行膨胀时,我收到此异常：

 ./res/layout/locations_list.xml line #-1 (sorry, not yet implemented): Error inflating class com.costum.android.widget.LoadMoreListView

我发现在充气自定义布局时会发生这种情况

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        return inflater.inflate(R.layout.locations_list, container, false);
    }

编辑这是locations_list.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    android:orientation="vertical" >

    <com.costum.android.widget.LoadMoreListView
        android:id="@+id/android:list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="0dp" />

</LinearLayout>

任何其他布局充气机工作,如在此测试中：

@Test
    public void testInflator() {
        ActivityController<SherlockFragmentActivity> activityController = CustomTestRunner
                .startActivity();
        SherlockFragmentActivity activity = activityController.get();
        LayoutInflater from = LayoutInflater.from(activity);
        View view = from
                .inflate(com.twisper.R.layout.locations_list_item, null);
        assertNotNull(view);
    }

我正在使用带有2.2-SNAPSHOT的Robolectric,现在我的问题是如何解决这个问题或者如何实现缺少的功能,robolectric文档非常稀疏,因此我很难找到任何起点.

我还在robolectrics问题跟踪器上发布了issue.

解决方法:

我想通了,如果你有这种情况,只需在XML中查找你的ID,即使这样

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

在一些示例代码中经常可以看到它必须是：

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