使用es preSSO单击视图内RecyclerView项目 [英] Using Espresso to click view inside RecyclerView item

问题描述

我如何使用长者preSSO点击里面的 RecyclerView 项的具体看法？我知道我可以用点击在位置0的项目：

How can I use Espresso to click a specific view inside a RecyclerView item? I know I can click the item at position 0 using:

OnView为（withId（R.id.recyclerView）） .perform（RecyclerViewActions.actionOnItemAtPosition（0，点击（）））;

onView(withId(R.id.recyclerView)) .perform(RecyclerViewActions.actionOnItemAtPosition(0, click()));

不过，我需要点击里面的项目，而不是项目本身的特定视图。

But I need to click on a specific view inside that item and not on the item itself.

在此先感谢。

要更precise：我有一个 RecyclerView （ R.id.recycler_view ）的项目是 CardView （ R.id.card_view ）。在每个 CardView 我有四个按钮（除其他事项外），我想点击一个特定的按钮（ R.id.bt_deliver ）。

To be more precise: I have a RecyclerView (R.id.recycler_view) which items are CardView (R.id.card_view). Inside each CardView I have four buttons (amongst other things) and I want to click on a specific button (R.id.bt_deliver).

我想用长者$ P $的新功能PSSO 2.0，但我不知道这是可能的。

I would like to use the new features of Espresso 2.0, but I'm not sure that is possible.

如果没有可能，我想用这样的事情（用托马斯·凯勒code）：

If not possible, I wanna use something like this (using Thomas Keller code):

onRecyclerItemView(R.id.card_view, ???, withId(R.id.bt_deliver)).perform(click());

但我不知道放什么的问号。

but I don't know what to put on the question marks.

推荐答案

您可以使用自定义视图动作做到这一点。

You can do it with customize view action.

public class MyViewAction {

    public static ViewAction clickChildViewWithId(final int id) {
        return new ViewAction() {
            @Override
            public Matcher<View> getConstraints() {
                return null;
            }

            @Override
            public String getDescription() {
                return "Click on a child view with specified id.";
            }

            @Override
            public void perform(UiController uiController, View view) {
                View v = view.findViewById(id);
                if (v != null) {
                    v.performClick();
                }
            }
        };
    }

}

然后，您可以点击它

Then you can click it with

onView(withId(R.id.rv_conference_list)).perform(
            RecyclerViewActions.actionOnItemAtPosition(0, MyViewAction.clickChildViewWithId(R.id. bt_deliver)));
