我一直在努力解决这个问题，我认为我没有得到关于 Robolectric 的基本知识。通常一些谷歌搜索可以帮助我深入了解这类问题，但在此之间并查看示例代码我没有找到任何有用的东西。

我正在尝试模拟单击列表视图项并检查单击后是否启动了活动。我不断地回想我正在测试的当前活动是结果活动。我尝试删除所有列表项单击代码并检查结果活动，这作为我正在测试的 InstallationListActivity 回来了。所以我得出的结论是列表视图项没有被点击，我只是不知道为什么。我在下面的测试代码中设置的系统日志是我期望的值。该列表有 13 个项目，getChildAt(0) 返回标题。我认为获取第一个项目 (getChildAt(1)) 并在其上调用 performClick 或其子文本视图会启动我预期的活动，但似乎并非如此。反正，

    @Before
    public void setUp() {
        mAppLaunch = new ApplicationLaunchActivity();
        mAppLaunch.onCreate(null);
        mActivity = new InstallationListActivity();
        mActivity.onCreate(null);
    }

    @Test
    public void shouldHaveNonEmptyInstallationList() throws Exception {
        assert(mActivity.installationListCount() > 0);
    }

    @Test
    public void shouldHaveSameNumberOfElements() throws Exception {
        ListView installationListView = (ListView) mActivity.getListView();

        ShadowListView shadowListView = shadowOf(installationListView);

        assert(shadowListView.getChildCount() == mActivity.installationListCount());
    }

    @Test
    public void pressingTheFirstItemInTheListShouldLaunchVenueListActivity() {
        ListView installationListView = (ListView) mActivity.findViewById(android.R.id.list);

        System.out.println("qty: " + installationListView.getChildCount());
        System.out.println("class: " + installationListView.getChildAt(0).getClass());
        System.out.println("class: " + installationListView.getChildAt(1).getClass());
        System.out.println("class: " + installationListView.getChildAt(2).getClass());
        System.out.println("class: " + installationListView.getChildAt(3).getClass());
        System.out.println("class: " + installationListView.getChildAt(4).getClass());

        LinearLayout firstItemLayout = (LinearLayout) installationListView.getChildAt(1);
        TextView firstItem = (TextView) firstItemLayout.getChildAt(0);

        ShadowTextView shadowFirstItem = shadowOf(firstItem);
        ShadowLinearLayout shadowLayout = (ShadowLinearLayout) shadowOf(firstItemLayout);

        shadowLayout.performClick();
        shadowFirstItem.performClick();

        clickOn(firstItem);
        clickOn(firstItemLayout);

        System.out.println("class: " + firstItemLayout.getChildAt(0).getClass());
        System.out.println("Layout shadow" + shadowOf(firstItemLayout).getClass());
        System.out.println("First Item Text: " + shadowFirstItem.getText());

        ShadowActivity shadowActivity = shadowOf(mActivity);
        Intent startedIntent = shadowActivity.getNextStartedActivity();
        assertNotNull(startedIntent);
        ShadowIntent shadowIntent = shadowOf(startedIntent);

        assertThat(shadowIntent.getComponent().getClassName(), equalTo(VenueListActivity.class.getName()));
    }
}

这是我用来构建列表视图的布局：

This is list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent">
    <ListView android:id="@android:id/list"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:cacheColorHint="#00000000"
              android:background="@drawable/background"/>
</LinearLayout>

list_item.xml


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/list_item"
              android:layout_height="fill_parent"
              android:layout_width="fill_parent">
    <TextView android:id="@+id/list_item_text"
              style="@style/tw_list_font"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:textAppearance="?android:attr/textAppearanceLarge"
              android:gravity="center_vertical"
              android:paddingLeft="6dip"
              android:minHeight="?android:attr/listPreferredItemHeight" />
</LinearLayout>

这是初始化列表的代码：

InstallationListActivity.java

setContentView(R.layout.list);
        final ListView installationListView = getListView();
        LayoutInflater inflater = getLayoutInflater();
        ViewGroup header = (ViewGroup) inflater.inflate(R.layout.header, installationListView, false);
        TextView headerText = (TextView) header.findViewById(R.id.header_text);
        headerText.setText("Installations On Live"); // TODO: This should not be hardcoded
        installationListView.addHeaderView(header, null, false);

        setListAdapter(new ArrayAdapter<Installation>(this, R.layout.list_item, R.id.list_item_text, mInstallations));

        // Click event
        installationListView.setClickable(true);
        installationListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long arg1) {
                Installation installationClicked = (Installation) installationListView.getItemAtPosition(position);
                if (LOCAL_LOG) {
                    Log.d(LOG_TAG, "Installation: " + installationClicked.toString() + " clicked.");
                    Log.d(LOG_TAG, installationClicked.toString() + " has installationDirectory: " +
                            installationClicked.rootDir);
                }
                AppState.installation = installationClicked;
                AppState.serverInstallationName = installationClicked.rootDir;
                Intent venueListIntent = new Intent(InstallationListActivity.this, VenueListActivity.class);
                startActivity(venueListIntent);
            }
        });

任何帮助深表感谢！万分感谢！

尝试辅助方法 performItemClick：

Robolectric.shadowOf(listView).performItemClick(position);
