java-Espresso“已启用”与所选视图不匹配

概述我正在使用Espresso2来测试按钮是否已启用.我的代码如下所示：onView(withId(R.id.fragment_vote_pause_btn)).check(matches(isEnabled()));我的按钮定义为：<Buttonandroid:id="@+id/fragment_vote_pause_btn"android:layout_width="wrap_content"

我正在使用Espresso 2来测试按钮是否已启用.我的代码如下所示：

  onVIEw(withID(R.ID.fragment_Vote_pause_btn)).check(matches(isEnabled()));

我的按钮定义为：

    <button        androID:ID="@+ID/fragment_Vote_pause_btn"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_alignParentBottom="true"        androID:layout_centerHorizontal="true"        androID:background="@androID:color/transparent"        androID:text="@string/audiowave_pause_or_play"        androID:textcolor="@drawable/play_pause_button_selector"        androID:textAllCaps="false"        androID:textSize="12sp" />

有时测试有效,但有时却出现以下异常：

有人知道吗？

解决方法:

在我看来,当您检查按钮是否启用时,您的按钮暂时不可见.

是不是正在检查尚未激活的窗口/按钮？也可能是 *** 作未同步,您必须等待使用空闲资源来启用/显示资源.
情况可能是：
1)活动未完全打开/加载(适配器等)
2)手势未完全完成(滚动等)
3)单击消息框后.

你是哪一个？出现故障时,您是否在设备屏幕上看到过？
