如何在Espresso中与alertdialog对话框交互？

// 导入所需的类
import androidx.test.espresso.Espresso;
import androidx.test.espresso.matcher.ViewMatchers;
import androidx.test.espresso.action.ViewActions;
import androidx.test.espresso.assertion.ViewAssertions;

// 在测试方法中执行交互操作
@Test
public void testAlertDialogInteraction() {
    // 点击按钮以触发AlertDialog的显示
    onView(ViewMatchers.withId(R.id.button_show_dialog)).perform(ViewActions.click());

    // 在AlertDialog中输入文本
    onView(ViewMatchers.withId(android.R.id.input)).perform(ViewActions.typeText("Hello"));

    // 点击AlertDialog中的确认按钮
    onView(ViewMatchers.withId(android.R.id.button1)).perform(ViewActions.click());

    // 验证AlertDialog已关闭
    onView(ViewMatchers.withId(android.R.id.button1)).check(ViewAssertions.doesNotExist());

    // 验证文本是否显示在TextView中
    onView(ViewMatchers.withId(R.id.text_view_result)).check(ViewAssertions.matches(ViewMatchers.withText("Hello")));
}
