when i set Recyclerview with single choice mode and do some operation with subview,there is some wrong.

[xgbxmgg]

when i use these "setChoiceMode(ItemSelectionSupport.ChoiceMode.SINGLE)" for recyclerview and do some operation with the recyclerview's sub view, like give a textview's text with another color.As png shows , i clicked position 1,but it set position 0's textview's text color.
