我正在尝试从特定视图访问按钮。同一视图显示 6 次。这是我正在使用的代码。

public void testTimeConfig(){
    onData(withDesc("description")).onChildView(withId(R.id.positive)).perform(click());
}

private static Matcher<Object> withDesc(String desc) {
    return allOf(is(instanceOf(String.class)), is(desc));
}

当我运行时，我得到一个错误：

在视图上执行“加载适配器数据”时出错，可以从类分配：类 android.widget.AdapterView。

这是访问子视图的最佳方式吗？如果是这样，怎么做？

编辑

这是我现在尝试使用的代码。

   onView(allOf((withContentDescription("description")), hasSibling(withContentDescription("SettingsLayout")), hasSibling(withId(R.id.positive)))).perform(click());

和

   onView(allOf((withContentDescription("description")), hasSibling(withId(R.id.positive)))).perform(click());

出现此错误：

根据您的最后评论，您应该使用onView()而不是onData(). 我认为您可以使用hasSibling()-示例单击按钮

onView(allOf(withId(R.id.positive), hasSibling(withDesc(someString))))
    .perform(click());

或没有自定义匹配器的示例（兄弟视图有文本）：

onView(allOf(withId(R.id.positive), hasSibling(withText(someString))))
    .perform(click());

或（兄弟视图有内容描述）：

onView(allOf(withId(R.id.positive), hasSibling(withContentDescription(someString))))
    .perform(click());

编辑：

好的，我会尝试这两种变体：

onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget))))
    .perform(click());

或者

onView(allOf(withId(R.id.increaseGoalButton), withParent(withId(R.id.timeGoalWidget))))
    .perform(click());

您的任何内容描述都不匹配字符串“描述”，这就是它找不到任何内容的原因。

假设按钮 id 是 R.id.positive，并且 id 在当前活动视图中是唯一的，您可以简单地使用：

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