如何靠近工具栏Espresso

Question

我有使用coordinatlayout,AppBarLayout和CollapsingToolbarLayout的布局.我想写一个点击列表中最后一项的测试.我滚动列表直到结束,然而,espresso中隐藏了所需的项目.要滚动列表,我使用:
onView(withId(R.id.widget_recycler_view)).perform(RecyclerViewActions.scrollToPosition(3)); 要隐藏,滚动工具栏,我尝试了以下代码:

onView(withId(R.id.coordinator_layout)).perform(swipeUp());
onView(withId(R.id.toolbar)).perform(swipeUp());

但是这段代码只隐藏了工具栏的一半,但这还不够.这是布局的代码:

我附上我的考试.如果你滚动手,它的工作原理:)但它是必要的机器人化过程.

    @Test
    public void addNewPhone(){
        onView(withId(R.id.widget_recycler_view)).perform(RecyclerViewActions.scrollToPosition(3));
        onView(withId(R.id.coordinator_layout)).perform(swipeUp());
        putDelay(2500);
        onView(withId(R.id.layout_add_phone)).perform(click());
        onView(withId(R.id.edit_letay_phone)).perform(replaceText("9586222922"));
        closeSoftKeyboard();
        onView(withText(R.string.add)).perform(click());
        closeSoftKeyboard();
        onView(withId(R.id.edit_code_letay_phone)).perform(replaceText("52461"));
        onView(withId(R.id.bt_code_request)).perform(click());
    }

我的问题是:滚动列表或布局时如何完全隐藏工具栏？

Answer 1

我在测试中使用以下自定义视图操作:

 public static ViewAction collapseAppBarLayout() {
    return new ViewAction() {
        @Override
        public Matcher<View> getConstraints() {
            return isAssignableFrom(AppBarLayout.class);
        }

        @Override
        public String getDescription() {
            return "Collapse App Bar Layout";
        }

        @Override
        public void perform(UiController uiController, View view) {
            AppBarLayout appBarLayout = (AppBarLayout) view;
            appBarLayout.setExpanded(false);
            uiController.loopMainThreadUntilIdle();
        }
    };
}

用法:

onView(withId(R.id.app_bar_layout)).perform(CustomViewActions.collapseAppBarLayout());

请注意,您需要在设备设置中禁用动画,否则,Espresso将不会等到它完全崩溃,然后才能继续下一步.
