| Methods Summary |
|---|
| void | animateOnFocus(boolean hasFocus)
final float zoom = hasFocus ? mFocusedZoom : 1f;
mRootView.animate().scaleX(zoom).scaleY(zoom).setDuration(mScaleDurationMs).start();
startShadowFocusAnimation(hasFocus, mScaleDurationMs);
enableOrbColorAnimation(hasFocus);
| | public void | enableOrbColorAnimation(boolean enable)Enables or disables the orb color animation.
Orb color animation is handled automatically when the orb is focused/unfocused,
however, an app may choose to override the current animation state, for example
when an activity is paused.
if (mColorAnimator != null) {
mColorAnimator.end();
mColorAnimator = null;
}
if (enable) {
// TODO: set interpolator (material if available)
mColorAnimator = ValueAnimator.ofObject(mColorEvaluator,
mColors.color, mColors.brightColor, mColors.color);
mColorAnimator.setRepeatCount(ValueAnimator.INFINITE);
mColorAnimator.setDuration(mPulseDurationMs * 2);
mColorAnimator.addUpdateListener(mUpdateListener);
mColorAnimator.start();
