本文介绍了onChildView 和 hasSiblings 与 Espresso的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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());}私有静态匹配器<对象>withDesc(字符串desc){返回 allOf(is(instanceOf(String.class)), is(desc));}

运行时出现错误:

<块引用>

在视图可从类中分配:类 android.widget.AdapterView"上执行加载适配器数据"时出错.

这是访问子视图的最佳方式吗?如果是，怎么办?

编辑

这是我现在尝试使用的代码.

<块引用>

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

和

<块引用>

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

出现此错误:

<块引用>

 在层次结构中没有找到匹配的视图

使用了 6 次的视图 xml.

这是我试图点击的 ID 为 increaseGoalButton 的 ImageView.

解决方案

根据您上次的评论，您应该使用 onView() 而不是 onData().我认为您可以使用 hasSibling() - 示例

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());

已

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

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

I am trying to access a button from a specific view. The same view is displayed 6 times. This is the code I am using.

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));
}

When I run, I get an error:

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

Is this the best way to access a child view? If so, how?

EDIT

This is the code I am trying to use now.

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

and

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

With this Error:

   No views in hierarchy found matching

It is the ImageView with id increaseGoalButton that I am trying to click.

解决方案

Based on your last comment you should use onView() instead of onData(). I think you'll be able to click the button using hasSibling() - example

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

or examples without your custom matcher (sibling view has text):

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

or (sibling view has content description):

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

EDITED:

OK, I'd try these two variants:

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

or

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