        //要写入的内容
        @Rule
        public ActivityTestRule<MainActivity> mainActivityTestRule = new ActivityTestRule<MainActivity>(MainActivity.class);

        @Test
        public void sayhello() {
            onView(withId(R.id.editText)).perform(typeText(STRING_To_Be_TYPED), closeSoftKeyboard());
            //获取editText的id,并将值写入
            onView(withText("say hello")).perform(click());
            //通过控件的文字定位按钮,并实现点击操作
            String expectedText = "Hello," + STRING_To_Be_TYPED + "!";
            //正确的输出内容
            onView(withId(R.id.textView)).check(matches(withText(expectedText)));
            //获取TextView的id,比对控件上的文字是否一致
        }
