如果要在设计预览中显示它们，则需要在ImageViews中指定Assertions.assertThat(planRepository.findAllBy(planA.getId())) // assert result size .hasSize(2) // extract a field to assert .extracting(ViewPlanDetailDto::getPlanDetail) // extract still finer fields to assert .extracting(PlanDetail::getId, p -> p.getModule().getName(), p -> p.getModule().geDescription(), ... other fields to assert) // declare values expected .containsExactly(Tuple.tuple(planDetailA.getId(), "CSS", "CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.", planDetailB.getId(), "HTML", "Hypertext Markup Language is the standard markup language for creating web pages and web applications.", ... other expected tuples ));。
如果您仅在Activity类中设置Image，例如

android:src="@..."

在程序执行之前它们不会显示。
