推荐答案

有没有内置的一个选择模式的结构支持， RecyclerView 。你的选择是要么推出自己或使用第三方库，提供它。 该 DynamicRecyclerView库提供选择的模式，但我还没有尝试过。

There is no built-in support for a "choice mode" structure with RecyclerView. Your options are to either roll it yourself or use a third-party library that offers it. The DynamicRecyclerView library offers choice modes, but I have not tried it.

此示例应用演示了使用已激活的状态，自己实现它，在这种情况下，以表示这是当前的选择。总体格局是：

This sample app demonstrates implementing it yourself, in this case using the activated state to indicate which is the current choice. The overall pattern is:

让你的 RecyclerView.ViewHolder 检测UI操作指示选择（点击某一行？点击一个单选按钮的行吗？等等）。

Have your RecyclerView.ViewHolder detect a UI operation that indicates a choice (click on a row? click on a RadioButton in the row? etc.).

跟踪选择的级别的 RecyclerView.Adapter 。在我的情况下， ChoiceCapableAdapter 处理，在与 SingleChoiceMode 类实现结合一个 ChoiceMode 策略。

Keep track of the selection at the level of your RecyclerView.Adapter. In my case, a ChoiceCapableAdapter handles that, in conjunction with a SingleChoiceMode class that implements a ChoiceMode strategy.

在作出选择，更新的新选择行以反映选择的和的更新previously选择的行以反映它不再是选择。 findViewHolderForPosition（）在 RecyclerView 能有所帮助 - 如果你跟踪位置， findViewHolderForPosition（）可以给你的 ViewHolder 对于这样的选择，这样你就可以取消选择吧。
