使用Espresso单击ListView中的特定复选框 [英] Click on a specific checkbox in a ListView using Espresso

问题描述

我有一个ListView，其中每一行都有一个复选框:

I have a ListView where each row has a checkbox:

现在，我想单击第四行的复选框.我有每一行的数据模型，因此我可以轻松地使用onData()选择具有给定数据的行.但是，如何单击该行中的复选框?

Now I want to click on the checkbox in the 4th row. I have the data model for each row, so I can easily use onData() to select a row with the given data. But how do I click on the checkbox in that row?

推荐答案

如果您的行布局允许单击该行以设置CheckBox，则可以使用它来单击ListView行:

If your row layout allows clicking on the row to set the CheckBox, you can use this to click the ListView row:

onData(anything()).atPosition(4).perform(click());

否则，您可以在不知道其ID的情况下直接单击CheckBox:

Otherwise you can click directly on the CheckBox without knowing its ID:

onData(anything())
   .atPosition(4)
   .onChildView(withClassName(Matchers.containsString("CheckBox")))
   .perform(click());

然后您可以断言CheckBox已选中:

You can then assert that the CheckBox is checked:

onData(anything())
   .atPosition(4)
   .onChildView(withClassName(Matchers.containsString("CheckBox")))
   .check(matches(isChecked()));
