Animate activity layout content when transitioning from one activity to another. 10 | 2. Animate shared elements (Hero views) in transitions between activities. 11 | 3. Animate view changes within same activity. 12 | 13 | 14 | ## 1. Transitions between Activities 15 | 16 | Animate existing activity layout **content** 17 | 18 | ![A Start B][transition_a_to_b] 19 | 20 | When transitioning from `Activity A` to `Activity B` content layout is animated according to defined transition. There are three predefined transitions available on `android.transition.Transition` you can use: **Explode**, **Slide** and **Fade**. 21 | All these transitions track changes to the visibility of target views in activity layout and animate those views to follow transition rules. 22 | 23 | [Explode][explode_link] | [Slide][slide_link] | [Fade][fade_link] 24 | --- | --- | --- 25 | ![transition_explode] | ![transition_slide] | ![transition_fade] 26 | 27 | 28 | You can define these transitions **declarative** using XML or **programmatically**. For the Fade Transition sample, it would look like this: 29 | 30 | ### Declarative 31 | Transitions are defined on XML files in `res/transition` 32 | 33 | > res/transition/activity_fade.xml 34 | 35 | ```xml 36 | 37 | 39 | 40 | ``` 41 | 42 | > res/transition/activity_slide.xml 43 | 44 | ```xml 45 | 46 | 48 | 49 | ``` 50 | 51 | To use these transitions you need to inflate them using `TransitionInflater` 52 | 53 | > MainActivity.java 54 | 55 | ```java 56 | @Override 57 | protected void onCreate(Bundle savedInstanceState) { 58 | super.onCreate(savedInstanceState); 59 | setContentView(R.layout.activity_transition); 60 | setupWindowAnimations(); 61 | } 62 | 63 | private void setupWindowAnimations() { 64 | Slide slide = TransitionInflater.from(this).inflateTransition(R.transition.activity_slide); 65 | getWindow().setExitTransition(slide); 66 | } 67 | 68 | ``` 69 | 70 | > TransitionActivity.java 71 | 72 | ```java 73 | @Override 74 | protected void onCreate(Bundle savedInstanceState) { 75 | super.onCreate(savedInstanceState); 76 | setContentView(R.layout.activity_transition); 77 | setupWindowAnimations(); 78 | } 79 | 80 | private void setupWindowAnimations() { 81 | Fade fade = TransitionInflater.from(this).inflateTransition(R.transition.activity_fade); 82 | getWindow().setEnterTransition(fade); 83 | } 84 | 85 | ``` 86 | 87 | ### Programmatically 88 | 89 | > MainActivity.java 90 | 91 | ```java 92 | @Override 93 | protected void onCreate(Bundle savedInstanceState) { 94 | super.onCreate(savedInstanceState); 95 | setContentView(R.layout.activity_transition); 96 | setupWindowAnimations(); 97 | } 98 | 99 | private void setupWindowAnimations() { 100 | Slide slide = new Slide(); 101 | slide.setDuration(1000); 102 | getWindow().setExitTransition(slide); 103 | } 104 | 105 | ``` 106 | 107 | > TransitionActivity.java 108 | 109 | ```java 110 | @Override 111 | protected void onCreate(Bundle savedInstanceState) { 112 | super.onCreate(savedInstanceState); 113 | setContentView(R.layout.activity_transition); 114 | setupWindowAnimations(); 115 | } 116 | 117 | private void setupWindowAnimations() { 118 | Fade fade = new Fade(); 119 | fade.setDuration(1000); 120 | getWindow().setEnterTransition(fade); 121 | } 122 | 123 | ``` 124 | 125 | #### Any of those produce this result: 126 | 127 | ![transition_fade] 128 | 129 | 130 | ### What is happening step by step: 131 | 132 | 1. Activity A starts Activity B 133 | 134 | 2. Transition Framework finds A Exit Transition (slide) and apply it to all visible views. 135 | 3. Transition Framework finds B Enter Transition (fade) and apply it to all visible views. 136 | 4. **On Back Pressed** Transition Framework executes Enter and Exit reverse animations respectively (If we had defined output `returnTransition` and `reenterTransition`, these have been executed instead) 137 | 138 | ### ReturnTransition & ReenterTransition 139 | 140 | Return and Reenter Transitions are the reverse animations for Enter and Exit respectively. 141 | 142 | * EnterTransition <--> ReturnTransition 143 | * ExitTransition <--> ReenterTransition 144 | 145 | If Return or Reenter are not defined, Android will execute a reversed version of Enter and Exit Transitions. But if you do define them, you can have different transitions for entering and exiting an activity. 146 | 147 | ![b back a][transition_b_to_a] 148 | 149 | We can modify previous Fade sample and define a `ReturnTransition` for `TransitionActivity`, in this case, a **Slide** transition. This way, when returning from B to A, instead of seeing a Fade out (reversed Enter Transition) we will see a **Slide out** transition 150 | 151 | > TransitionActivity.java 152 | 153 | ```java 154 | @Override 155 | protected void onCreate(Bundle savedInstanceState) { 156 | super.onCreate(savedInstanceState); 157 | setContentView(R.layout.activity_transition); 158 | setupWindowAnimations(); 159 | } 160 | 161 | private void setupWindowAnimations() { 162 | Fade fade = new Fade(); 163 | fade.setDuration(1000); 164 | getWindow().setEnterTransition(fade); 165 | 166 | Slide slide = new Slide(); 167 | slide.setDuration(1000); 168 | getWindow().setReturnTransition(slide); 169 | } 170 | 171 | ``` 172 | 173 | 174 | Observe that if no Return Transition is defined then a reversed Enter Transition is executed. 175 | If a Return Transition is defined that one is executed instead. 176 | 177 | Without Return Transition | With Return Transition 178 | --- | --- 179 | Enter: `Fade In` | Enter: `Fade In` 180 | Exit: `Fade Out` | Exit: `Slide out` 181 | ![transition_fade] | ![transition_fade2] 182 | 183 | 184 | ## 2. Shared elements between Activities 185 | 186 | The idea behind this is having two different views in two different layouts and link them somehow with an animation. 187 | 188 | Transition framework will then do _whatever animations it consider necessary_ to show the user a transition from one view to another. 189 | 190 | Keep this always in mind: the view **is not really moving** from one layout to another. They are two independent views. 191 | 192 | 193 | ![A Start B with shared][shared_element] 194 | 195 | 196 | ### a) Enable Window Content Transition 197 | 198 | This is something you need to set up once on your app `styles.xml`. 199 | 200 | > values/styles.xml 201 | 202 | ```xml 203 | 208 | ``` 209 | 210 | Here you can also specify default enter, exit and shared element transitions for the whole app if you want 211 | 212 | ```xml 213 | 224 | ``` 225 | 226 | 227 | 228 | ### b) Define a common transition name 229 | 230 | To make the trick you need to give both, origin and target views, the same **`android:transitionName`**. They may have different ids or properties, but `android:transitionName` must be the same. 231 | 232 | > layout/activity_a.xml 233 | 234 | ```xml 235 | 240 | ``` 241 | 242 | > layout/activity_b.xml 243 | 244 | ```xml 245 | 250 | ``` 251 | 252 | ### c) Start an activity with a shared element 253 | 254 | Use the `ActivityOptions.makeSceneTransitionAnimation()` method to define shared element origin view and transition name. 255 | 256 | > MainActivity.java 257 | 258 | ```java 259 | 260 | blueIconImageView.setOnClickListener(new View.OnClickListener() { 261 | @Override 262 | public void onClick(View v) { 263 | Intent i = new Intent(MainActivity.this, SharedElementActivity.class); 264 | 265 | View sharedView = blueIconImageView; 266 | String transitionName = getString(R.string.blue_name); 267 | 268 | ActivityOptions transitionActivityOptions = ActivityOptions.makeSceneTransitionAnimation(MainActivity.this, sharedView, transitionName); 269 | startActivity(i, transitionActivityOptions.toBundle()); 270 | } 271 | }); 272 | 273 | ``` 274 | 275 | 276 | Just that code will produce this beautiful transition animation: 277 | 278 | ![a to b with shared element][shared_element_anim] 279 | 280 | As you can see, Transition framework is creating and executing an animation to create the illusion that views are moving and changing shape from one activity to the other 281 | 282 | ## Shared elements between fragments 283 | 284 | Shared element transition works with Fragments in a very similar way as it does with activities. 285 | 286 | Steps **a)** and **b)** are exactly the **same**. Only **c)** changes 287 | 288 | ### a) Enable Window Content Transition 289 | 290 | > values/styles.xml 291 | 292 | ```xml 293 | 298 | ``` 299 | 300 | ### b) Define a common transition name 301 | 302 | > layout/fragment_a.xml 303 | 304 | ```xml 305 | 310 | ``` 311 | 312 | > layout/fragment_b.xml 313 | 314 | ```xml 315 | 320 | ``` 321 | 322 | ### c) Start a fragment with a shared element 323 | 324 | To do this you need to include shared element transition information as part of the **`FragmentTransaction`** process. 325 | 326 | ```java 327 | FragmentB fragmentB = FragmentB.newInstance(sample); 328 | 329 | // Defines enter transition for all fragment views 330 | Slide slideTransition = new Slide(Gravity.RIGHT); 331 | slideTransition.setDuration(1000); 332 | sharedElementFragment2.setEnterTransition(slideTransition); 333 | 334 | // Defines enter transition only for shared element 335 | ChangeBounds changeBoundsTransition = TransitionInflater.from(this).inflateTransition(R.transition.change_bounds); 336 | fragmentB.setSharedElementEnterTransition(changeBoundsTransition); 337 | 338 | getFragmentManager().beginTransaction() 339 | .replace(R.id.content, fragmentB) 340 | .addSharedElement(blueView, getString(R.string.blue_name)) 341 | .commit(); 342 | ``` 343 | 344 | And this is the final result: 345 | 346 | ![shared_element_no_overlap] 347 | 348 | ## Allow Transition Overlap 349 | 350 | You can define if enter and exit transitions can overlap each other. 351 | 352 | From [Android documentation](http://developer.android.com/intl/ko/reference/android/app/Fragment.html#getAllowEnterTransitionOverlap()): 353 | > When **true**, the enter transition will start as soon as possible. 354 | > 355 | > When **false**, the enter transition will wait until the exit transition completes before starting. 356 | 357 | This works for both Fragments and Activities shared element transitions. 358 | 359 | ```java 360 | FragmentB fragmentB = FragmentB.newInstance(sample); 361 | 362 | // Defines enter transition for all fragment views 363 | Slide slideTransition = new Slide(Gravity.RIGHT); 364 | slideTransition.setDuration(1000); 365 | sharedElementFragment2.setEnterTransition(slideTransition); 366 | 367 | // Defines enter transition only for shared element 368 | ChangeBounds changeBoundsTransition = TransitionInflater.from(this).inflateTransition(R.transition.change_bounds); 369 | fragmentB.setSharedElementEnterTransition(changeBoundsTransition); 370 | 371 | // Prevent transitions for overlapping 372 | fragmentB.setAllowEnterTransitionOverlap(overlap); 373 | fragmentB.setAllowReturnTransitionOverlap(overlap); 374 | 375 | getFragmentManager().beginTransaction() 376 | .replace(R.id.content, fragmentB) 377 | .addSharedElement(blueView, getString(R.string.blue_name)) 378 | .commit(); 379 | ``` 380 | 381 | It is very easy to spot the difference in this example: 382 | 383 | Overlap True | Overlap False 384 | --- | --- 385 | Fragment_2 appears on top of Fragment_1 | Fragment_2 waits until Fragment_1 is gone 386 | ![shared_element_overlap] | ![shared_element_no_overlap] 387 | 388 | 389 | 390 | ## 3. Animate view layout elements 391 | 392 | ### Scenes 393 | Transition Framework can also be used to animate element changes within current activity layout. 394 | 395 | Transitions happen between scenes. A scene is just a regular layout which **defines a static state of our UI**. You can transition from one scene to another and Transition Framework will animate views in between. 396 | 397 | ```java 398 | scene1 = Scene.getSceneForLayout(sceneRoot, R.layout.activity_animations_scene1, this); 399 | scene2 = Scene.getSceneForLayout(sceneRoot, R.layout.activity_animations_scene2, this); 400 | scene3 = Scene.getSceneForLayout(sceneRoot, R.layout.activity_animations_scene3, this); 401 | scene4 = Scene.getSceneForLayout(sceneRoot, R.layout.activity_animations_scene4, this); 402 | 403 | (...) 404 | 405 | @Override 406 | public void onClick(View v) { 407 | switch (v.getId()) { 408 | case R.id.button1: 409 | TransitionManager.go(scene1, new ChangeBounds()); 410 | break; 411 | case R.id.button2: 412 | TransitionManager.go(scene2, TransitionInflater.from(this).inflateTransition(R.transition.slide_and_changebounds)); 413 | break; 414 | case R.id.button3: 415 | TransitionManager.go(scene3, TransitionInflater.from(this).inflateTransition(R.transition.slide_and_changebounds_sequential)); 416 | break; 417 | case R.id.button4: 418 | TransitionManager.go(scene4, TransitionInflater.from(this).inflateTransition(R.transition.slide_and_changebounds_sequential_with_interpolators)); 419 | break; 420 | } 421 | } 422 | ``` 423 | 424 | That code would produce transition between four scenes in the same activity. Each transition has a different animation defined. 425 | 426 | Transition Framework will take all visible views in current scene and calculate whatever necessary animations are needed to arrange those views according to next scene. 427 | 428 | ![scenes_anim] 429 | 430 | 431 | ### Layout changes 432 | 433 | Transition Framework can also be used to animate layout property changes in a view. You just need to make whatever changes you want and it will perform necessary animations for you 434 | 435 | #### a) Begin Delayed Transition 436 | 437 | With just this line of code we are telling the framework we are going to perform some UI changes that it will need to animate. 438 | 439 | ```java 440 | TransitionManager.beginDelayedTransition(sceneRoot); 441 | ``` 442 | #### b) Change view layout properties 443 | 444 | 445 | ```java 446 | ViewGroup.LayoutParams params = greenIconView.getLayoutParams(); 447 | params.width = 200; 448 | greenIconView.setLayoutParams(params); 449 | 450 | ``` 451 | 452 | Changing view width attribute to make it smaller will trigger a `layoutMeasure`. At that point the Transition framework will record start and ending values and will create an animation to transition from one to another. 453 | 454 | 455 | ![view layout animation][view_layout_anim] 456 | 457 | 458 | ## 4. (Bonus) Shared elements + Circular Reveal 459 | Circular Reveal is just an animation to show or hide a group of UI elements. It is available since API 21 in `ViewAnimationUtils` class. 460 | 461 | 462 | Circular Reveal animation can be used in combination of Shared Element Transition to create meaningful animations that smoothly teach the user what is happening in the app. 463 | 464 | ![reveal_shared_anim] 465 | 466 | What is happening in this example step by step is: 467 | 468 | * Orange circle is a shared element transitioning from `MainActivity` to `RevealActivity`. 469 | * On `RevealActivity` there is a listener to listen for shared element transition end. When that happens it does two things: 470 | * Execute a Circular Reveal animation for the Toolbar 471 | * Execute a scale up animation on `RevealActivity` views using plain old `ViewPropertyAnimator` 472 | 473 | 474 | > Listen to shared element enter transition end 475 | 476 | ```java 477 | Transition transition = TransitionInflater.from(this).inflateTransition(R.transition.changebounds_with_arcmotion); 478 | getWindow().setSharedElementEnterTransition(transition); 479 | transition.addListener(new Transition.TransitionListener() { 480 | @Override 481 | public void onTransitionEnd(Transition transition) { 482 | animateRevealShow(toolbar); 483 | animateButtonsIn(); 484 | } 485 | 486 | (...) 487 | 488 | }); 489 | 490 | ``` 491 | 492 | > Reveal Toolbar 493 | 494 | ```java 495 | private void animateRevealShow(View viewRoot) { 496 | int cx = (viewRoot.getLeft() + viewRoot.getRight()) / 2; 497 | int cy = (viewRoot.getTop() + viewRoot.getBottom()) / 2; 498 | int finalRadius = Math.max(viewRoot.getWidth(), viewRoot.getHeight()); 499 | 500 | Animator anim = ViewAnimationUtils.createCircularReveal(viewRoot, cx, cy, 0, finalRadius); 501 | viewRoot.setVisibility(View.VISIBLE); 502 | anim.setDuration(1000); 503 | anim.setInterpolator(new AccelerateInterpolator()); 504 | anim.start(); 505 | } 506 | ``` 507 | 508 | > Scale up activity layout views 509 | 510 | ```java 511 | private void animateButtonsIn() { 512 | for (int i = 0; i < bgViewGroup.getChildCount(); i++) { 513 | View child = bgViewGroup.getChildAt(i); 514 | child.animate() 515 | .setStartDelay(100 + i * DELAY) 516 | .setInterpolator(interpolator) 517 | .alpha(1) 518 | .scaleX(1) 519 | .scaleY(1); 520 | } 521 | } 522 | ``` 523 | 524 | ### More circular reveal animations 525 | 526 | There are many different ways you can create a reveal animation. The important thing is to use the animation to help the user understand what is happening in the app. 527 | 528 | #### Circular Reveal from the middle of target view 529 | 530 | ![reveal_green] 531 | 532 | ```java 533 | int cx = (viewRoot.getLeft() + viewRoot.getRight()) / 2; 534 | int cy = viewRoot.getTop(); 535 | int finalRadius = Math.max(viewRoot.getWidth(), viewRoot.getHeight()); 536 | 537 | Animator anim = ViewAnimationUtils.createCircularReveal(viewRoot, cx, cy, 0, finalRadius); 538 | viewRoot.setBackgroundColor(color); 539 | anim.start(); 540 | ``` 541 | 542 | #### Circular Reveal from top of target view + animations 543 | 544 | ![reveal_blue] 545 | 546 | ```java 547 | int cx = (viewRoot.getLeft() + viewRoot.getRight()) / 2; 548 | int cy = (viewRoot.getTop() + viewRoot.getBottom()) / 2; 549 | int finalRadius = Math.max(viewRoot.getWidth(), viewRoot.getHeight()); 550 | 551 | Animator anim = ViewAnimationUtils.createCircularReveal(viewRoot, cx, cy, 0, finalRadius); 552 | viewRoot.setBackgroundColor(color); 553 | anim.addListener(new AnimatorListenerAdapter() { 554 | @Override 555 | public void onAnimationEnd(Animator animation) { 556 | animateButtonsIn(); 557 | } 558 | }); 559 | anim.start(); 560 | ``` 561 | 562 | 563 | #### Circular Reveal from touch point 564 | 565 | ![reveal_yellow] 566 | 567 | ```java 568 | @Override 569 | public boolean onTouch(View view, MotionEvent motionEvent) { 570 | if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) { 571 | if (view.getId() == R.id.square_yellow) { 572 | revealFromCoordinates(motionEvent.getRawX(), motionEvent.getRawY()); 573 | } 574 | } 575 | return false; 576 | } 577 | ``` 578 | 579 | ```java 580 | private Animator animateRevealColorFromCoordinates(int x, int y) { 581 | float finalRadius = (float) Math.hypot(viewRoot.getWidth(), viewRoot.getHeight()); 582 | 583 | Animator anim = ViewAnimationUtils.createCircularReveal(viewRoot, x, y, 0, finalRadius); 584 | viewRoot.setBackgroundColor(color); 585 | anim.start(); 586 | } 587 | ``` 588 | 589 | #### Animate and Reveal 590 | 591 | ![reveal_red] 592 | 593 | ```java 594 | Transition transition = TransitionInflater.from(this).inflateTransition(R.transition.changebounds_with_arcmotion); 595 | transition.addListener(new Transition.TransitionListener() { 596 | @Override 597 | public void onTransitionEnd(Transition transition) { 598 | animateRevealColor(bgViewGroup, R.color.red); 599 | } 600 | (...) 601 | 602 | }); 603 | TransitionManager.beginDelayedTransition(bgViewGroup, transition); 604 | RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 605 | layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT); 606 | btnRed.setLayoutParams(layoutParams); 607 | ``` 608 | 609 | 610 | # Sample source code 611 | 612 | **[https://github.com/lgvalle/Material-Animations](https://github.com/lgvalle/Material-Animations/)** 613 | 614 | 615 | # More information 616 | 617 | * Alex Lockwood posts about Transition Framework.
