我正在尝试从特定视图访问按钮.相同的视图显示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));
}

当我跑步时,我收到一个错误:

在视图上执行'加载适配器数据'时出错'可从类中分配:class android.widget.AdapterView'.

这是访问子视图的最佳方式吗？如果是这样,怎么样？
