Android - Espresso - 长选项菜单 - 单击不可见的选项菜单项

Question

Espresso如何点击长选项菜单中尚未显示的(选项)菜单项？

打开选项菜单很简单:

openActionBarOverflowOrOptionsMenu( getInstrumentation().getTargetContext());

我试过例如scrollTo,但它没有成功:

onView( withText("Option menu item text")).perform( scrollTo(), click());

onView( withText( R.id.optionMenuId)).perform( scrollTo(), click());

onView( withId( is( R.id.appOptionMenu))).perform( swipeDown()); // where SwipeDown is a simple utility method on GeneralSwipeAction.

onData( anything()).inAdapterView( withId(R.id.wpeOptionMenu)).atPosition( 12).perform(click()); // I guess because it is not an adapter

你有一个很好的解决方案吗？

ActionBar溢出菜单是一个包含ListView的PopUpWindow.

scrollTo()仅适用于ScrollView的后代,因此在此处不起作用.

因为您想要的视图位于AdapterView中,所以您需要使用onData.

数据对象是AdapterView,类型为MenuItem,您希望匹配Menu项的标题.像这样的东西:

onData(allOf(instanceOf(MenuItem.class), withTitle(title))).perform(click());

static MenuItemTitleMatcher withTitle(String title) {
    return new MenuItemTitleMatcher(title);
}

class MenuItemTitleMatcher extends BaseMatcher<Object> {
    private final String title;
    public MenuItemTitleMatcher(String title) { this.title = title; }

    @Override public boolean matches(Object o) {
        if (o instanceof MenuItem) {
            return ((MenuItem) o).getTitle().equals(title);
        }
        return false;
    }
    @Override public void describeTo(Description description) { }
}
