Android Radio Button

In Android, you can utilize "android.widget.RadioButton" class to render radio catch, and those radio catches are normally gathered by android.widget.RadioGroup. 

Android radio catch is a gadget which can have more than alternative to browse and the client can pick just a single choice at any given moment. 

Radio catches enable the client to choose one alternative from a set. You should utilize radio catches for discretionary sets that are totally unrelated on the off chance that you feel that the client needs to see every single accessible alternative one next to the other. In the event that it's not important to demonstrate all choices one next to the other, utilize a spinner. 

In the event that RadioButtons are in gathering, when one RadioButton inside a gathering is chosen, all others are naturally deselected. 

A radio catch comprises of two states – checked and unchecked. Clicking an unchecked catch changes its state to "checked" state and "unchecked" for the recently chosen radio catch 

A portion of the traits of android radio catch and radio gathering are recorded beneath: 

android:orientation 

check(id) 

clearCheck()
