Public Constructors

public CompoundButton (Context context)

public CompoundButton (Context context, AttributeSet attrs)

public CompoundButton (Context context, AttributeSet attrs, int defStyle)

Public Methods

public boolean isChecked ()

public void onRestoreInstanceState (Parcelable state)

Hook allowing a view to re-apply a representation of its internal state that had previously been generated by onSaveInstanceState(). This function will never be called with a null state.

Parameters

state	The frozen state that had previously been returned by onSaveInstanceState().

public Parcelable onSaveInstanceState ()

Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.

Returns

Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save. The default implementation returns null.

public boolean performClick ()

Call this view's OnClickListener, if it is defined.

Returns

True there was an assigned OnClickListener that was called, false otherwise is returned.

public void setButtonDrawable (Drawable d)

Set the background to a given Drawable

Parameters

d	The Drawable to use as the background

public void setButtonDrawable (int resid)

Set the background to a given Drawable, identified by its resource id.

Parameters

resid	the resource id of the drawable to use as the background

public void setChecked (boolean checked)

Changes the checked state of this button.

Parameters

checked	true to check the button, false to uncheck it

public void setOnCheckedChangeListener (CompoundButton.OnCheckedChangeListener listener)

Register a callback to be invoked when the checked state of this button changes.

Parameters

listener	the callback to call on checked state change

public void toggle ()

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

Protected Methods

protected void drawableStateChanged ()

This function is called whenever the state of the view changes in such a way that it impacts the state of drawables being shown.

Be sure to call through to the superclass when overriding this function.

protected int[] onCreateDrawableState (int extraSpace)

Generate the new Drawable state for this view. This is called by the view system when the cached Drawable state is determined to be invalid. To retrieve the current state, you should use getDrawableState().

Parameters

extraSpace	if non-zero, this is the number of extra entries you would like in the returned array in which you can place your own states.

Returns

Returns an array holding the current Drawable state of the view.

protected void onDraw (Canvas canvas)

Implement this to do your drawing.

Parameters

canvas	the canvas on which the background will be drawn

protected boolean verifyDrawable (Drawable who)

If your view subclass is displaying its own Drawable objects, it should override this function and return true for any Drawable it is displaying. This allows animations for those drawables to be scheduled.

Be sure to call through to the super class when overriding this function.

Parameters

who	The Drawable to verify. Return true if it is one you are displaying, else return the result of calling through to the super class.

Returns

boolean If true than the Drawable is being displayed in the view; else false and it is not allowed to animate.
