Methods Summary
public android.animation.ObjectAnimator	addAnimTo(long duration, long delay, java.lang.String property, float toValue, boolean replace) Adds an animation that interpolates given property from its current value to the given value. param duration the duration, in ms. param delay the delay to start the animation, in ms. param property the property to animate param toValue the target value param replace if true, replace the current animation with this one. if (replace) removeAnimationFor(property); ObjectAnimator anim = ObjectAnimator.ofFloat(this, property, toValue); anim.setDuration(duration); anim.setStartDelay(delay); anim.setInterpolator(EASE_OUT_INTERPOLATOR); this.addAnimation(anim, replace); if (DBG) Log.v(TAG, "animationCount = " + mAnimators.size()); return anim;
private com.android.internal.widget.DrawableHolder	addAnimation(android.animation.ObjectAnimator anim, boolean overwrite) Adds the given animation to the list of animations for this object. param anim param overwrite return if (anim != null) mAnimators.add(anim); mNeedToStart.add(anim); return this;
public void	clearAnimations() Stops all animations and removes them from the list. for (ObjectAnimator currentAnim : mAnimators) { currentAnim.cancel(); } mAnimators.clear();
public void	draw(android.graphics.Canvas canvas) Draw this object to the canvas using the properties defined in this class. param canvas canvas to draw into final float threshold = 1.0f / 256.0f; // contribution less than 1 LSB of RGB byte if (mAlpha <= threshold) // don't bother if it won't show up return; canvas.save(Canvas.MATRIX_SAVE_FLAG); canvas.translate(mX, mY); canvas.scale(mScaleX, mScaleY); canvas.translate(-0.5f*getWidth(), -0.5f*getHeight()); mDrawable.setAlpha((int) Math.round(mAlpha * 255f)); mDrawable.draw(canvas); canvas.restore();
public float	getAlpha() return mAlpha;
public android.graphics.drawable.BitmapDrawable	getDrawable() return mDrawable;
public int	getHeight() return mDrawable.getIntrinsicHeight();
public float	getScaleX() return mScaleX;
public float	getScaleY() return mScaleY;
public int	getWidth() return mDrawable.getIntrinsicWidth();
public float	getX() return mX;
public float	getY() return mY;
public void	onAnimationCancel(android.animation.Animator animation)
public void	onAnimationEnd(android.animation.Animator animation) mAnimators.remove(animation);
public void	onAnimationRepeat(android.animation.Animator animation)
public void	onAnimationStart(android.animation.Animator animation)
public void	removeAnimationFor(java.lang.String property) Stops all animations for the given property and removes it from the list. param property ArrayList<ObjectAnimator> removalList = (ArrayList<ObjectAnimator>)mAnimators.clone(); for (ObjectAnimator currentAnim : removalList) { if (property.equals(currentAnim.getPropertyName())) { currentAnim.cancel(); } }
public void	setAlpha(float alpha) mAlpha = alpha;
public void	setScaleX(float value) mScaleX = value;
public void	setScaleY(float value) mScaleY = value;
public void	setX(float value) mX = value;
public void	setY(float value) mY = value;
public void	startAnimations(ValueAnimator.AnimatorUpdateListener listener) Starts all animations added since the last call to this function. Used to synchronize animations. param listener an optional listener to add to the animations. Typically used to know when to invalidate the surface these are being drawn to. for (int i = 0; i < mNeedToStart.size(); i++) { ObjectAnimator anim = mNeedToStart.get(i); anim.addUpdateListener(listener); anim.addListener(this); anim.start(); } mNeedToStart.clear();
