Transition动画

if(TransitionHelper.isSysTransitionEnable()) {
final Pair<View, String>[] pairs = TransitionHelper.createSafeTransitionParticipants(
HomeActivity.this, false,
new Pair<>((ImageView) view.findViewById(R.id.iv_item_profile)
, getString(R.string.transition_image))
);
Intent intent = new Intent(HomeActivity.this, DetailActivity.class);
intent.putExtra(DetailActivity.KEY_USE_SYS_TRANSITION, true);
TransitionsEntity entity = new TransitionsEntity();
entity.setUrl(adapter.getItem(position).getUrl());
intent.putExtra(DetailActivity.KEY_ENTITY, entity);
ActivityOptionsCompat transitionActivityOptions = ActivityOptionsCompat.makeSceneTransitionAnimation(HomeActivity.this, pairs);
startActivity(intent, transitionActivityOptions.toBundle());
}else{
int[] locs = new int[2];
clickImage = (ImageView) view.findViewById(R.id.iv_item_profile);
clickImage.getLocationOnScreen(locs);
clickOrigin = new TransitionsEntity();
clickOrigin.setLeft(locs[0]);
clickOrigin.setTop(locs[1]);
clickOrigin.setWidth(clickImage.getWidth());
clickOrigin.setHeight(clickImage.getHeight());
HomeEntity item = (HomeEntity) adapter.getItem(position);
clickOrigin.setUrl(item.getUrl());
GlideUtils.displayImage(getApplicationContext(), ivTrans, item.getUrl(), R.drawable.def_placeholder);
Intent intent = new Intent(HomeActivity.this, DetailActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.putExtra(DetailActivity.KEY_ENTITY, false);
intent.putExtra(DetailActivity.KEY_ENTITY, clickOrigin);
startActivityForResult(intent, REQUEST_CODE_DEF);
overridePendingTransition(0, 0);
}
}

ivDetail.setTranslationX(lastTranX);
ivDetail.setTranslationY(lastTranY);
ivDetail.setVisibility(View.VISIBLE);
rlDetailRoot.postDelayed(new Runnable() {
@Override
public void run() {
TransitionManager.beginDelayedTransition(rlDetailRoot, new TranslationTransition().setPathMotion(new ArcMotion()).setDuration(200));
ivDetail.setTranslationX(0);
ivDetail.setTranslationY(0);
}
}, 20);

blur动画

Blurry.with(getActivity())
.radius(10)
.sampling(newSampling)
.async(new Blurry.ImageComposer.ImageComposerListener() {
@Override
public void onImageReady(BitmapDrawable drawable) {
if(lastAlpha == 1f){
ivDetailHeader.setImageBitmap(srcHeaderBg);
}  else {
ivDetailHeader.setImageDrawable(drawable);
}
}
})
.from(srcHeaderBg)
.into(ivDetailHeader)

recyclerview动画

rvDetailEvents.setItemAnimator(new SlideInLeftAnimator());
rvDetailEvents.getItemAnimator().setAddDuration(500);
rvDetailEvents.getItemAnimator().setRemoveDuration(500);
