All Implemented Interfaces:

Drawable.Callback, ViewManager, ViewParent

public class RelativeRadioGroup
extends RelativeLayout

This class is used to create a multiple-exclusion scope for a set of radio buttons. Checking one radio button that belongs to a radio group unchecks any previously checked radio button within the same group.

Initially, all of the radio buttons are unchecked. While it is not possible to uncheck a particular radio button, the radio group can be cleared to remove the checked state.

Constructor Details

RelativeRadioGroup

public RelativeRadioGroup(Context context)

Method Details

onViewAdded

protected void onViewAdded(View child)

Description copied from class: ViewGroup

Called when a new child is added to this ViewGroup. Overrides should always call super.onViewAdded.

Overrides:

onViewAdded in class ViewGroup

Parameters:

child - the added child view

onViewRemoved

protected void onViewRemoved(View child)

Description copied from class: ViewGroup

Called when a child view is removed from this ViewGroup. Overrides should always call super.onViewRemoved.

Overrides:

onViewRemoved in class ViewGroup

Parameters:

child - the removed child view

check

public void check(int id)

Sets the selection to the radio button whose identifier is passed in parameter. Using View.NO_ID as the selection identifier clears the selection; such an operation is equivalent to invoking clearCheck().

Parameters:

id - the unique id of the radio button to select in this group

See Also:

• getCheckedId()
• clearCheck()

getCheckedId

public final int getCheckedId()

Returns the identifier of the selected radio button in this group. Upon empty selection, the returned value is View.NO_ID.

Returns:

the unique id of the selected radio button in this group

See Also:

• check(int)
• clearCheck()

clearCheck

public final void clearCheck()

Clears the selection. When the selection is cleared, no radio button in this group is selected and getCheckedId() returns View.NO_ID.

See Also:

• check(int)
• getCheckedId()

setOnCheckedChangeListener

public void setOnCheckedChangeListener(@Nullable
 RelativeRadioGroup.OnCheckedChangeListener listener)

Register a callback to be invoked when the checked radio button changes in this group.

Parameters:

listener - the callback to call on checked state change

generateDefaultLayoutParams

@Nonnull
protected ViewGroup.LayoutParams generateDefaultLayoutParams()

Description copied from class: ViewGroup

Returns a set of default layout parameters. These parameters are requested when the View passed to ViewGroup.addView(View) has no layout parameters already set. If null is returned, an exception is thrown from addView.

Overrides:

generateDefaultLayoutParams in class RelativeLayout

Returns:

a set of default layout parameters
