Android Switch, validating before toggling switch

Question

I have a Switch, or a SwitchCompat rather on my app.

When the user clicks or slides the switch I would like to run some code to determine if they should be allowed to.

I have tried the

setOnCheckedChangeListener and setOnClickListener methods but both allow the graphic of the slider to toggle before running the validation code.

How can I run my own code before anything else when the switch is pressed?

Thanks

Answer 1

you should write your validation code first. if validation is false they not allowed to press switch using setEnabled(false) the else user is allowed to press switch

Answer 2

We have three options

1. One you have tried by setOnCheckedChangeListener()
2. Other is to disable the view entirely by using setEnabled()
3. You may try using setOnTouchListener and write your validation code there, and if the user is not allowed to do the functionality just return true else return false

Returning true would make the Switch believe the touch was handled and it won't do any actions for the same
