我正在尝试将简单的点击视图添加到回收站视图的项目中，但由于某种原因，我必须单击一次项目而不是一次以执行操作。单击时，回收器View似乎没有检测到点击。然而，在下一个上它会检测到点击并执行适当的操作。

我似乎无法找到导致此问题的问题。我可以得到任何帮助。感谢。

所以我发现了这个问题。以下两个标签是这里的罪魁祸首
android:focusable="true"
android:focusableInTouchMode="true"
当我们设置focusable和focusableInTouchMode = true时，基本上意味着您启用视图以首先关注触摸然后能够点击。

我遇到了类似的问题，但是将焦点设置为false的解决方案在我的情况下不起作用。
相反，我的问题是我在持有我的Recycler视图的活动中设置了onItemTouch监听器。
USE [OperationsView]
DECLARE @ProductionDate As DateTime
DECLARE @tag_in As VARCHAR(80)
DECLARE @FCChemGALPERMIN float
DECLARE @pi_server As VARCHAR(32)
DECLARE @endDate As DateTime
DECLARE @Debug As Bit
DECLARE @result As Float
SELECT @ProductionDate = '2016-12-01 07:00:00'
SELECT @tag_in = 'I-FC-835'
SELECT @pi_server = 'valpi'
SELECT @endDate = DATEADD(DAY, 1, @productionDate)
SELECT @Debug = 1
EXEC @FCChemGALPERMIN = Interface.proc_GetPIValueAverageTime
@result, @tag_in, @ProductionDate, @endDate, @pi_server, @Debug
PRINT @FCChemGALPERMIN
PRINT 'done'
通过从我的活动中删除它，我的其他触摸听众开始响应单击而不仅仅是双倍。
