android - 如何从 Espresso 重复使用的 Fragment 中获取多个相同 ID 的 EditText View ？

Question

我正在尝试使用 onView() 获取位于 fragment 内部的 EditText View ，但每个 fragment 中的每个 EditText 都具有相同的 ID。

给定这个伪代码:

<Activity>
    <Fragment>
         <EditText android:id="@+id/input" />
    </Fragment>
    <Fragment>
         <EditText android:id="@+id/input" />
    </Fragment>
    <Fragment>
         <EditText android:id="@+id/input" />
    </Fragment>
</Activity>

在我的测试用例中，我在做

onView(withId(R.id.input)).perform(typeText("foo"));

运行时，我得到 id: com.foo.bar.foobar:id/input' 匹配层次结构中的多个 View 。。 View 层次结构如下:(为了便于阅读，我将“MATCHES”移到了元素之前)

我试过:

EditText input = mActivity.getSupportFragmentManager()
            .findFragmentByTag("foo")
            .getView()
            .findViewById(R.id.input);

onView(withId(input)); 

但我也遇到了问题。我还没有找到任何解决这个特定问题的方法。任何帮助将不胜感激。

Answer 1

根据我的理解，您必须以某种方式区分 TextView。假设第一个 fragment 的 ID 为“fragment1”，第二个 fragment 的 ID 为“fragment2”，依此类推。

那么你可以使用

onView(allOf(withParent(withId(R.id.fragment1)),instanceOf(EditText.class))).perform(typeText("foo"));

仅选择该 fragment 中的单个 TextView 并在您的测试用例中使用它。
