AppCompatRadioButton

A radio button is a two-states button that can be either checked or unchecked. When the radio button is unchecked, the user can press or click it to check it. However, contrary to a CheckBox, a radio button cannot be unchecked by the user once checked.

Radio buttons are normally used together in a RadioGroup. When several radio buttons live inside a radio group, checking one radio button unchecks all the others.

See the Radio Buttons guide.

Public methods

getAccessibilityClassName

Added in API level 23

CharSequence getAccessibilityClassName ()

Return the class name of this object to be used for accessibility purposes. Subclasses should only override this if they are implementing something that should be seen as a completely new class of view when used by accessibility, unrelated to the class it is deriving from. This is used to fill in AccessibilityNodeInfo.setClassName.

Returns
`CharSequence`

toggle

Added in API level 1

void toggle ()

Change the checked state of the view to the inverse of its current state

If the radio button is already checked, this method will not toggle the radio button.
