Question

当导航抽屉包含带有图像和文本视图的行列表时，如何单击导航抽屉项？

我使用了以下的Espresso测试源示例：git / testapp_test / src / main / java / com / google / android / apps / common / testing / ui / testapp / DrawerActionsTest.java

我从贡献中检索了DrawerActions和DrawerMatchers，并将它们放在我的测试项目中。

导航抽屉行为：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="48dp" 
    android:background="@drawable/list_selector">

    <ImageView
        android:id="@+id/icon"
        etc ... />

    <TextView
        android:id="@+id/title"
        etc.... />

</RelativeLayout>

导航项目是：

public class NavDrawerItem {
    public String title;
    public int icon;
    ....

    // a matcher
    @Override
    public boolean equals( Object mob2) {
        String otherName = ((NavDrawerItem) mob2).title;
        return( title.equals( otherName));
    }
}

NavigationDrawerAdapter填充导航抽屉视图。

Espresso测试源打开抽屉，关闭它，重新打开它......但我找不到第一个“导入”项目的匹配项。因此，测试会在执行点击时停止。

代码是：

public LearnerAppAutoTest() {
    super(MainActivity.class);
}
@Override
protected void setUp() throws Exception {
    super.setUp();
    getActivity();
}

public void testOpenAndCloseDrawer() {
    openDrawer(R.id.drawer_layout);
    closeDrawer(R.id.drawer_layout);

    openDrawer(R.id.drawer_layout);
    onView(withId(R.id.drawer_layout)).check(matches(isOpen()));

    String rowContents = "Import";

    // Option 1: too many lists having an "Import" string
    onData( allOf( is( instanceOf( String.class)), is( rowContents))).perform(click());

    // Option 2: selecting on NavDrawerItem.class and a matcher
    //    ... still all matches, also in other lists match. Why? They don't have NavDrawerItems. 
    onData( allOf( is( instanceOf( NavDrawerItem.class)), is( rowContents))).perform(click());

    // Option 3: custom matcher
    //   ... still all matches, also in other lists match. Why?
    onData( allOf( instanceOf( NavDrawerItem.class), navDrawerItemHavingName( rowContents))).perform( click());

  }

所以，无论我编程什么，都有多个匹配器......甚至来自没有NavDrawerItem类的列表。

Answer 1

试试这个：

Espresso.onView(Matchers.allOf(ViewMatchers.withId(R.id.drawerItemNameTextView), ViewMatchers.hasSibling(ViewMatchers.withText(((NavDrawerItem)item).getItemName())))).perform(ViewActions.click());
