我的应用的Reyclerview是“ android.support.v7.widget.RecyclerView” 我用的是androidx的意式浓缩咖啡。
我向我的gradle中添加了依赖项，如下所示：
androidTestImplementation 'androidx.annotation:annotation:' + rootProject.androidxLibVersion;
androidTestImplementation 'androidx.recyclerview:recyclerview:' + rootProject.androidxLibVersion;
androidTestImplementation 'androidx.test:core:' + rootProject.coreVersion
androidTestImplementation 'androidx.test.ext:junit:' + rootProject.extJUnitVersion
androidTestImplementation 'androidx.test:runner:' + rootProject.runnerVersion
androidTestImplementation 'androidx.test.espresso:espresso-core:' + rootProject.espressoVersion
androidTestImplementation 'androidx.test.espresso:espresso-contrib:' + rootProject.espressoVersion
androidTestImplementation 'androidx.test.espresso:espresso-intents:' + rootProject.espressoVersion
但是，当我尝试使用
import androidx.recyclerview.widget.RecyclerView
import androidx.test.espresso.contrib.RecyclerViewActions
...
RecyclerViewActions.scrollToPosition<RecyclerView.ViewHolder>(position)
它说
由于：java.lang.RuntimeException：将不执行操作 因为目标视图与以下一项或多项不匹配 约束：（可从类：类分配 androidx.recyclerview.widget.RecyclerView并显示在 屏幕显示给用户）目标视图：“ RecyclerView {id = 2131296674， res-name = media_content_recyclerview，可见度= VISIBLE，宽度= 1440， 高度= 2384，has-focus = false，has-focusable = true， has-window-focus = true，is-clickable = false，is-enabled = true， is-focused = false，is-focusable = true，is-layout-requested = false， is-selected = false， layout-params=android.widget.RelativeLayout$LayoutParams@e32b046， tag = null，root-is-layout-requested = false，has-input-connection = false， x = 0.0，y = 192.0，child-count = 15}“
我的代码有什么问题吗？
