  • RadioGroup

    public RadioGroup(Context context,
              AttributeSet attrs)

• Method Detail

  • setOnHierarchyChangeListener

    public void setOnHierarchyChangeListener(ViewGroup.OnHierarchyChangeListener listener)

    Register a callback to be invoked when a child is added to or removed from this view.

    Overrides:

    setOnHierarchyChangeListener in class ViewGroup

    Parameters:

    listener - the callback to invoke on hierarchy change

  • onFinishInflate

    protected void onFinishInflate()

    Finalize inflating a view from XML. This is called as the last phase of inflation, after all child views have been added.

    Even if the subclass overrides onFinishInflate, they should always be sure to call the super method, so that we get called.

    Overrides:

    onFinishInflate in class View

  • addView

    public void addView(View child,
               int index,
               ViewGroup.LayoutParams params)

    Description copied from class: ViewGroup
    Adds a child view with the specified layout parameters.

    Note: do not invoke this method from View.draw(android.graphics.Canvas), View.onDraw(android.graphics.Canvas), ViewGroup.dispatchDraw(android.graphics.Canvas) or any related method.

    Overrides:

    addView in class ViewGroup

    Parameters:

    child - the child view to add

    index - the position at which to add the child

    params - the layout parameters to set on the child

  • check

    public void check(int id)

    Sets the selection to the radio button whose identifier is passed in parameter. Using -1 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:

    getCheckedRadioButtonId(), clearCheck()

  • getCheckedRadioButtonId

    public int getCheckedRadioButtonId()

    Returns the identifier of the selected radio button in this group. Upon empty selection, the returned value is -1.

    Returns:

    the unique id of the selected radio button in this group

    See Also:

    check(int), clearCheck()

  • clearCheck

    public void clearCheck()

    Clears the selection. When the selection is cleared, no radio button in this group is selected and getCheckedRadioButtonId() returns null.

    See Also:

    check(int), getCheckedRadioButtonId()

  • setOnCheckedChangeListener

    public void setOnCheckedChangeListener(RadioGroup.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

  • generateLayoutParams

    public RadioGroup.LayoutParams generateLayoutParams(AttributeSet attrs)

    Returns a new set of layout parameters based on the supplied attributes set.

    Overrides:

    generateLayoutParams in class LinearLayout

    Parameters:

    attrs - the attributes to build the layout parameters from

    Returns:

    an instance of ViewGroup.LayoutParams or one of its descendants

  • checkLayoutParams

    protected boolean checkLayoutParams(ViewGroup.LayoutParams p)

    Overrides:

    checkLayoutParams in class LinearLayout

  • generateDefaultLayoutParams

    protected LinearLayout.LayoutParams generateDefaultLayoutParams()

    Description copied from class: LinearLayout
    Returns a set of layout parameters with a width of ViewGroup.LayoutParams.MATCH_PARENT and a height of ViewGroup.LayoutParams.WRAP_CONTENT when the layout's orientation is LinearLayout.VERTICAL. When the orientation is LinearLayout.HORIZONTAL, the width is set to ViewGroup.LayoutParams.WRAP_CONTENT and the height to ViewGroup.LayoutParams.WRAP_CONTENT.

    Overrides:

    generateDefaultLayoutParams in class LinearLayout

    Returns:

    a set of default layout parameters or null

  • onInitializeAccessibilityEvent

    public void onInitializeAccessibilityEvent(AccessibilityEvent event)

    Description copied from class: View
    Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.

    Example: Setting the password property of an event in addition to properties set by the super implementation:

     public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
         super.onInitializeAccessibilityEvent(event);
         event.setPassword(true);
     }

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

    Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.

    Overrides:

    onInitializeAccessibilityEvent in class LinearLayout

    Parameters:

    event - The event to initialize.

    See Also:

    View.sendAccessibilityEvent(int), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)

  • onInitializeAccessibilityNodeInfo

    public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)

    Description copied from class: View
    Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:

    • AccessibilityNodeInfo.setParent(View),
    • AccessibilityNodeInfo.setBoundsInParent(Rect),
    • AccessibilityNodeInfo.setBoundsInScreen(Rect),
    • AccessibilityNodeInfo.setPackageName(CharSequence),
    • AccessibilityNodeInfo.setClassName(CharSequence),
    • AccessibilityNodeInfo.setContentDescription(CharSequence),
    • AccessibilityNodeInfo.setEnabled(boolean),
    • AccessibilityNodeInfo.setClickable(boolean),
    • AccessibilityNodeInfo.setFocusable(boolean),
    • AccessibilityNodeInfo.setFocused(boolean),
    • AccessibilityNodeInfo.setLongClickable(boolean),
    • AccessibilityNodeInfo.setSelected(boolean),

    Subclasses should override this method, call the super implementation, and set additional attributes.

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.

    Overrides:

    onInitializeAccessibilityNodeInfo in class LinearLayout

    Parameters:

    info - The instance to initialize.
