Robolectric，与点击列表项问题 [英] Robolectric, Problems with clicking list items

问题描述

我一直在努力奋斗着这个问题了一下，我觉得我没有得到一些有关Robolectric根本。通常一些谷歌搜索可以帮助我得到这个类型的问题的底部，但之间在看样品code，我没有找到使用的东西。

I have been struggling with this problem a bit, and I think I am not getting something fundamental about Robolectric. Usually some google searches can help me get to the bottom of this type of problem, but between that and looking at the sample code I am not finding anything of use.

我试图模仿一个列表视图项的点击，并检查一个活动后，点击启动。我一直得到回来，目前的活动我测试的是产生的活动。我试图消除所有的列表项单击code和检查所产生的活动，这回来的，我测试InstallationListActivity。于是，我来到了该列表视图项目不被点击的结论，我只是不知道为什么。我已经设置了下面的测试code的系统日志，我希望他们是价值观。该列表是13项内容，并且getChildAt（0）返回的标题。我认为，获得第一项（getChildAt（1）），并在其上​​或其子文本视图中调用performClick将推出我的预期活动，但似乎并不如此。总之，这里是robolectric /测试code我使用的：

I am trying to emulate a click on a list view item and check that an activity is launched after the click. I keep getting back that the current activity I am testing is the resulting activity. I tried removing all of the list item clicking code and checking the resulting activity, and this came back as the InstallationListActivity that I am testing. So I came to the conclusion that the list view item is not being clicked, and I am just not sure why. The system logs that I have set up in the testing code below are the values that I expect them to be. The list is 13 items, and the getChildAt(0) returns the header. I would think that getting the first item (getChildAt(1)) and calling performClick on it or its child text view would launch my expected activity, but that doesn't seem to be the case. Anyway, here is the robolectric/testing code I am using:

    @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()));
    }
}

下面是布局的我用来生成列表视图：

Here is the layout's I am using to build the list view:

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>

这里是code初始化列表：

And here is the code that initializes the list:

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);
            }
        });

任何帮助是非常AP preciated！由于一吨！

Any help is much appreciated! Thanks a ton!

推荐答案

尝试辅助方法performItemClick：

Try the helper method performItemClick:

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