Animate Me! if you don't do it for me, do it for Chet - DroidconLondon2015

Published on

This is the slide of the conference gave at the DroidCon London 2015 by Mathias Seguy.
The pitch:
Animation is a key point when building your application….
But, “Animation is complicated with Android”, is your feeling.
Well, in fact, it’s not. I will show you how simples they are, how magic they could be and how fun your application can become.
I will explains which animation to use for which version of the system, what are your choices and what is your strategy. We will have a complete overview on the Android Animation framework.
So I hope to see you in the room for this conference, because at the end, your application will be enhanced :)

Animate Me! if you don't do it for me, do it for Chet - DroidconLondon2015

  1. 1. #AnimateMe by(Mathias Seguy== Android2EE){ French AndroidTrainer}
  2. 2. If you don't do it for me, do it for chet !
  3. 3. Demonstration !
  4. 4. Animation is life Animationis comprehension Animation is engagements Animationis delightedyour UX Animationis necessary Animation is simple
  5. 5. Make Animations simple
  6. 6. Because we wantyou to animate your application !
  7. 7. Alpha Rotate Translate Scale And the plan transformations are yours V1 <set android:interpolator="@[package:]anim/interpolator_resource"> <alpha android:duration="float" android:fromAlpha="float" android:toAlpha="float" /> <scale android:duration="float" android:fromXScale="float" android:toXScale="float" android:fromYScale="float" android:toYScale="float" android:pivotX="float" android:pivotY="float" /> <translate android:duration="float" android:fromXDelta="float" android:toXDelta="float" android:fromYDelta="float" android:toYDelta="float" /> <rotate android:duration="float" android:fromDegrees="float" android:toDegrees="float" android:pivotX="float" android:pivotY="float" /> <set> ... </set> </set> Animation animIn= AnimationUtils.loadAnimation(ctx, R.anim.generic_anim); edtMessage.startAnimation(animIn); animation/generic_anim.xml Onlychange pixelsnotthe state of the view
  8. 8. Makes animations generic V11 /** * The in Animation for after HC */ AnimatorSet animInHC; animInHC = (AnimatorSet) AnimatorInflater.loadAnimator(ctx, R.animator.generic_anim); animInHC.setTarget(edtMessage); animInHC.setTarget(btnAdd); animInHC.start(); <set > <objectAnimator android:duration="1000" android:propertyName="translationX" android:valueFrom="-250" android:valueTo="0" android:valueType="floatType" /> <objectAnimator android:duration="1000" android:propertyName="scaleX" android:valueFrom="0.0" android:valueTo="1.0" android:valueType="floatType" /> </set> animator-v11/generic_anim.xml Changes the state of the object
  9. 9. Uses Handler and Runnable Simplebut dangerous(memory leak, runs inUI thread, can generates frames drops) Not optimized Animationis changingthe view/objectstate by droppingchanges inthe UI thread Handler clipDrawableHandler=new Handler(); Runnable clipDrawableRunnable=new Runnable() { @Override public void run() { myView.changeSomething(level); clipDrawableHandler.postDelayed(clipDrawableRunnable,32); } }; V1
  10. 10. Uses Handler and Runnable Simplebut dangerous(memory leak, runs inUI thread, can generates frames drops) Not optimized V11 Animationis changingthe view/objectstate by droppingchanges inthe UI thread Handler clipDrawableHandler=new Handler(); Runnable clipDrawableRunnable=new Runnable() { @Override public void run() { myView.changeSomething(level); clipDrawableHandler.postDelayed(clipDrawableRunnable,32); } };
  11. 11. Don't be scared, it's simple. How do yougofrom the pointfromto the pointto? V1 t1t0 v0 v1 from to ? i(t)=v, where i(t0)=v0 and i(t1)=v1 float time
  12. 12. It can be straight V1 t1t0 v0 v1 from to linear
  13. 13. t1t0 v0 v1 Youcan use the system's ones V1 t1t0 v0 v1 from to deceleration acceleration to from t1t0 v0 v1 to bouncing from <set android:interpolator= "@android:anim/accelerate_interpolator"> <set android:interpolator= "@android:anim/decelerate_interpolator"> <set android:interpolator= "@android:anim/bounce_interpolator" >
  14. 14. Or buildyour own. V1 t1t0 v0 v1 from to alcoholic public class MyInterpolator implements Interpolator { float v; @Override public float getInterpolation(float input) { //v=i(input) return v; }...}
  15. 15. myDrawable= (ImageView)findViewById(R.id.imvToto).getDrawable(); <ImageView android:id="@+id/imvToto" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" android:src="@drawable/my_drawable"/> V1

  25. 25. The constraints that killfor path transformation: "Note that the paths must be compatible for morphing.In more details, the paths shouldhave exact same lengthof commands , and exact same lengthof parameters for each commands." It means: youwon't use it expect for so simpletrick (arrow to hamburger). =>Waiting for tools ! V21
  26. 26. And here it is !!! https://github.com/bonnyfone/vectalign V21
  27. 27. To create Svg and/orsimplify them https://inkscape.org/ To convertSvg intoVectorDrawable http://inloop.github.io/svg2android/ A goodpractice : Define your path in aString file (resvaluesmy_path_string.xml) V21 But even with that it's the hell on earth =>working ona Github project
  28. 28. Make it simple and magic: Youcan animate any view translationX ,translationY, rotationX, rotationY, rotation, scaleX, scaleY, pivotX,pivotY, x,y,alphaand more with onelineof code! myView.animate().setDuration(300).x(20).rotationY(60).start(); V13
  29. 29. myView.animate().rotation(360); is equivalent to ObjectAnimator.ofFloat(myView, "rotation", 0f, 360f).start(); V13
  30. 30. Makes animations simple,magic and generic V13
  31. 31. First extends what youwant (Objector View or what ever) public class BlueDot extends View { V13
  32. 32. Define the propertyto animate using set/*MyProperty*/ public class BlueDot extends View { /** * The property to animate * * @param parameter value of the state to calculate the animation of the object */ private void setToto(int parameter) { /*Do your stuff, (call invalidate to redraw view)*/ V13
  33. 33. Then animate public class BlueDot extends View { /** * The property to animate * @param parameter value of the state to calculate the animation of the object */ private void setToto(int parameter) {/*Do your stuff,(call invalidate to redraw view)*/ ObjectAnimator.ofInt(blueDot, "toto", 0, 110) .start(); V13
  34. 34. ClipDrawable Handler clipDrawableHandler=new Handler(); Runnable clipDrawableRunnable=new Runnable() { @Override public void run() {level++; clipDrawableHorizontal.setLevel(level); clipDrawableHandler.postDelayed(clipDrawableRunnable,32); } }; <?xml version="1.0" encoding="utf-8"?> <clip xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/ic_android2ee" android:clipOrientation="horizontal" android:gravity="left" /> It was before Works with every think ! V13
  35. 35. Works with every think ! public class MyActivity extends Activity{ private void setMoveDrawable(int level){ clipDrawableHorizontal.setLevel(level); } private void animateDrawable() { ObjectAnimator.ofInt(this, "MoveDrawable", 0, 10000).start(); } No more Handler neither Runnable!!! yes thanks Chet ! V13
  36. 36. Demonstration ! v16

How to get the screen size ? @SuppressLint("NewApi") private void getViewSize() { //this is an usual trick when we want to know the dimension of our view //initialize dimensions of the view WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); if (postICS) { Point size = new Point(); display.getSize(size); width = size.x; height = size.y; } else { width = display.getWidth(); // deprecated height = display.getHeight(); // deprecated } } V1
  72. 72. Whencustomizing youview, youhave to overwrite the followingmethod: protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(w, h, oldw, oldh); this.w = w; this.h = h; centerX = w / 2; centerY = h / 2; //...} V1
  73. 73. Use the ViewTreeObserver private void getEditButtonWidth() { //this is an usual trick when we want to know the dimension of the elements of our view //find the dimension of the EditButton ViewTreeObserver vto = btnEdit.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { btnEdit.getViewTreeObserver().removeGlobalOnLayoutListener(this); btnEditWidth = btnEdit.getMeasuredWidth(); } }); } V1
  74. 74. Use the LayoutParameter of the ViewGroup private void changeImvSprite1Size(){ //Change the LayoutParameter to change the size of view if(isImvSprite1Expended){ imvSprite1.setLayoutParams(imvSpritesLayoutParamNormal); }else{ imvSprite1.setLayoutParams(imvSpritesLayoutParamExpanded); } isImvSprite1Expended=!isImvSprite1Expended; } private void initializeImvSpriteSize() { //get the real size of the components imvSprite1Height = imvSprite1.getMeasuredHeight(); //initialize the layout parameter for the normal size imvSpritesLayoutParamNormal = new LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, imvSprite1Height); //initialize the layout parameter for the expanded size imvSpritesLayoutParamExpanded= new LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, 2*imvSprite1Height);} private LinearLayout.LayoutParams imvSpritesLayoutParamNormal, imvSpritesLayoutParamExpanded ; V1
  75. 75. Invalidate and dirtyArea or layoutRequest V1
  76. 76. Make yourownpaint : Paint dotPaint= new Paint(); //initialize the shader (stuff that make the color of the paint depending on // the location in the screen and a set of colors) //@chiuki at droidcon london int[] rainbow = getRainbowColors(); Shader shader = new LinearGradient(0, 0, 0, w, rainbow, null, Shader.TileMode.MIRROR); Matrix matrix = new Matrix(); matrix.setRotate(90); shader.setLocalMatrix(matrix); dotPaint.setShader(shader); private int[] getRainbowColors() { return new int[]{ getResources().getColor(R.color.rainbow_red), getResources().getColor(R.color.rainbow_yellow), getResources().getColor(R.color.rainbow_green), getResources().getColor(R.color.rainbow_turquoise), getResources().getColor(R.color.rainbow_blue), getResources().getColor(R.color.rainbow_purple) };} V1
  77. 77. First: Simplifyyour layout!!! if not enoughyoucan also: User LayerType Hardware accelerated btnDoNotPress.setLayerType(View.LAYER_TYPE_HARDWARE,null); new Animator.AnimatorListener() { public void onAnimationEnd(Animator animation) { btnDoNotPress.setLayerType(View.LAYER_TYPE_NONE, null); } V1
