我的应用程序具有MainActivity，该框架具有充当容器的framelayout。

在屏幕之间导航时，我使用此容器填充不同的片段。现在，在这些片段之一中

主要活动：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <include layout="@layout/toolbar" />


    <android.support.v4.widget.DrawerLayout
        android:layout_width="match_parent"
        android:id="@+id/drawerLayout"
        android:layout_height="match_parent">

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <!-- Framelayout to display Fragments -->
            <FrameLayout
                android:id="@+id/frame_container"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>


        </FrameLayout>



        <!-- navigation drawer -->
        <RelativeLayout
            android:layout_gravity="left"
            android:layout_width="match_parent"
            android:background="#fff"
            android:layout_height="match_parent">

            <ListView
                android:id="@+id/left_drawer"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#fff"
                android:dividerHeight="1dp"
                android:divider="@drawable/transparent"
                />
        </RelativeLayout>

我想在此选择带有espresso的storiesCommentsLinLayout或storiesBodyOnlyTextLayout。

我尝试使用onData（withClild（anyOf（withText（“ mySampleText”）））））并收到错误

android.support.test.espresso.PerformException: Error performing 'load adapter data' on view 'is assignable from class: class android.widget.AdapterView'.

在android.app.Instrumentation $ InstrumentationThread.run（Instrumentation.java:1970）

当使用onData语句时，您将使用数据类（如io.newfaces.bo.Story您所见），而不是使用Views。因此，您应该定义io.newfaces.bo.StoryonData中的匹配项，然后可以在与该数据相对应的View上执行必要的操作。

像这样的东西：

onData(allOf(is(new BoundedMatcher<Object, Person>(Person.class) {
    @Override
    public void describeTo(Description description) {
    }
    @Override
    protected boolean matchesSafely(Story story) {
        return story.id == 123;
   }
})))

我在这里期望您的Story对象具有一个ID（例如）。
