1, a TextView view layout, an error: This view is not the constraint.
Error: 2, simulator System UI is not responding.
What reason be excuse me, how to solve? Thank you,

CodePudding user response:

TextView error is because you use the constraint layout, you haven't the TextView constraint control,

CodePudding user response:

Pair with ConstraintLayout, you must control with constraints on the horizontal and vertical direction, unless it is all the layout in this direction, namely match_parent

CodePudding user response:

The first problem is that you use the outer ConstraintLayout layout, your TextView will add Constraint relevant properties, similar to your BottomNavitagionView above

CodePudding user response:

Positive solution on the ground floor, you connect the control in your view that you logged out again
