Question

无法使用Espresso单击元素。代码是

onView(withId(R.id.nav_btn_menu)).perform(click());

我想单击上面的ImageButton，但是它抛出错误为

android.support.test.espresso.PerformException: Error performing 'single click - At Coordinates: 727, 1207 and precision: 16, 16' on view 'with id: com.xyz.p2p.app:id/nav_btn_menu'.

Test running failed: Instrumentation run failed due to 'Process crashed.'

注意：可以单击同一页面上同一行中的其他按钮。实际上，有两个按钮的可见性切换。同一位置的其他按钮的元素也显示相同的错误。

有人可以告诉我我在做什么错吗？

我有一个类似的问题，它是ImageView而不是ImageButton。我就像您能够测试类似视图的点击，而不仅仅是一个按钮。唯一的区别是，在imageView中，我正在旋转图像，但是当我移除旋转后，它才起作用

 <ImageView
    android:id="@+id/image"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:layout_marginEnd="8dp"
    android:rotation="180"
    android:src="@drawable/back"
    app:layout_constraintBottom_toBottomOf="@+id/top_view"
    app:layout_constraintEnd_toEndOf="@+id/top_view"
    app:layout_constraintTop_toTopOf="parent" />

这是引起问题的原因： android：rotation =“ 180”

无法点击图像按钮
