AnimatedVectorDrawableCompat not starting the Animation? - android

I am trying to implement Morphing animation using AnimatedVectorDrawableCompat class. Basically I am trying to achieve animation as Evernote App - note Edit functionality (where user press on Edit button and Back button Morphed to Tick Button).
I have done following in .JAVA file :
private AnimatedVectorDrawableCompat arrowDoneAnimatedVectorDrawable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_compose_note);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
if (null != getSupportActionBar()) {
getSupportActionBar().setDisplayShowTitleEnabled(false);
arrowDoneAnimatedVectorDrawable = AnimatedVectorDrawableCompat.create(this, R.drawable.animation_vector_consolidated);
getSupportActionBar().setHomeAsUpIndicator(arrowDoneAnimatedVectorDrawable);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
findViewById(R.id.fab_edit_note).setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (arrowDoneAnimatedVectorDrawable.isRunning()) {
arrowDoneAnimatedVectorDrawable.stop();
} else {
arrowDoneAnimatedVectorDrawable.start();
}
}
Below is consolidated .XML to Morph Back button path to tick button :
<?xml version="1.0" encoding="utf-8"?>
<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:igonore="NewApi"
android:drawable="#drawable/ic_arrow_back_black_24dp">
<target
android:animation="#animator/arrow_done_transition"
android:name="head"/>
</animated-vector>
Below .XML file is to run an Animator on button paths :
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#integer/morphing_time"
android:propertyName="pathData"
android:valueType="pathType"
android:valueFrom="M 20.0,11.0 H 7.83 l 5.59,-5.59 L 12.0,4.0 l -8.0,8.0 l 8.0,8.0 L 12.0,20.0 L 12.0,20.0 l 1.41,-1.41 L 7.83,13.0 H 20.0 v -2.0 L 20.0,11.0"
android:valueTo="M 9.0,16.2 H 9.0 l 0.0,0.0 L 4.8,12.0 l 0.0,0.0 l -1.4,1.4 L 9.0,19.0 L 21.0,7.0 l -1.4,-1.4 L 9.0,16.2 H 9.0 v 0.0 L 9.0,16.2"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
/>
I have used VectAlign to align both the icon paths.
And, finally this is how Back button Vector look like :
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="24.0"
android:viewportHeight="24.0">
<path
android:fillColor="#FF000000"
android:pathData="M 20.0,11.0 H 7.83 l 5.59,-5.59 L 12.0,4.0 l -8.0,8.0 l 8.0,8.0 L 12.0,20.0 L 12.0,20.0 l 1.41,-1.41 L 7.83,13.0 H 20.0 v -2.0 L 20.0,11.0"/>
</vector>
I have spend around two days to figure out the morphing concept and its implementation but still no luck. Am I missing or doing something wrong here..
Thanks.

Android Animated Vector Drawable doesn't work properly

I have the following ImageView
<androidx.appcompat.widget.AppCompatImageView
android:id="#+id/image_header_toggle"
android:layout_width="28dp"
android:layout_height="28dp"
android:layout_marginEnd="10dp"

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="#+id/text_header_name"

and two animated drawables that I made through https://shapeshifter.design/

and this code that I use to toggle the icons
val res = if (isExpanded) R.drawable.ic_header_off_to_on else R.drawable.ic_header_on_to_off
image_header_toggle.setImageResource(res)
(view.image_header_toggle.drawable as? AnimatedVectorDrawable)?.start()
image_header_toggle.setOnClickListener { isExpanded = !isExpanded }
The off_to_on animation seems to play nicely but the on_to_off one doesn't, the image simply gets replace.
It looks like this >_<
I just found this question and tried something out. A more elegant solution is to remove your Kotlin code with mine. This will achieve a smooth transition and you even can change the duration of it. Instead of needing 2 drawables you can just use one. If you are using Fragment instead of Activity, don't forget to set view.findViewById instead of findViewById:
class MainActivity : AppCompatActivity() {
private var isExpanded = true
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val imageView = findViewById<ImageView>(R.id.image_header_toggle)
imageView.setOnClickListener {
if (!isExpanded) {
imageView.animate().apply {
duration = 500
rotation(0f)
isExpanded = true}
}else{
imageView.animate().apply {
duration = 500
rotation(-90f)
isExpanded = false}
}
}
}
}

How to add Animated Vector Drawable Animation?

I am trying to animate a vector path to a different path in my android app for testing but its not working properly . no animation is displayed on screen and neither any animation is shown.
My vector file is:
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="8dp"
android:height="5dp"
android:viewportWidth="8"
android:viewportHeight="5">
<path
android:name="redot"
android:pathData="M2.5,2.5L6,2.5"
android:strokeWidth="4"
android:fillColor="#00000000"
android:strokeColor="#E61B1B"
android:fillType="evenOdd"
android:strokeLineCap="round"/>
</vector>
And my VectorAnimation file is:
<?xml version="1.0" encoding="utf-8"?>
<animated-vector xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
tools:targetApi="lollipop"
android:drawable="#drawable/ic_reddot">
<target
android:animation="#anim/redanim"
android:name="redot"/>
</animated-vector>
My Animation file in anim folder is:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
android:duration="10000"
android:propertyName="pathData"
android:valueFrom="M2.5,2.5L6,2.5"
android:valueTo="M2.5,2.5L31,2.5"
android:valueType="pathType" />
</set>
And finally my MainActivityCode is as following:
public class MainActivity extends AppCompatActivity {
private TextView testObj;
private ImageView reddot;
private AnimatedVectorDrawable animation;
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// testObj = (TextView) findViewById(R.id.testObj);
// testObj.setVisibility(View.INVISIBLE);
reddot = (ImageView) findViewById(R.id.reddot);
Drawable d = reddot.getBackground();
if (d instanceof AnimatedVectorDrawable) {
Log.d("testanim", "onCreate: instancefound" );
animation = (AnimatedVectorDrawable) d;
animation.start();
}
}
}
Use Shape Shifter tool and than export the animated vector drawable file generated by shape shifter . add this file in your drawable folder and than add this as background to your imageview which you want to animate
my avd_anim.xml file:
<animated-vector
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:aapt="http://schemas.android.com/aapt">
<aapt:attr name="android:drawable">
<vector
android:name="vector"
android:width="80dp"
android:height="12dp"
android:viewportWidth="80"
android:viewportHeight="12">
<path
android:name="path"
android:pathData="M 6 6 L 74 6"
android:strokeColor="#e61b1b"
android:strokeWidth="12"
android:strokeLineCap="round"
android:fillType="evenOdd"/>
</vector>
</aapt:attr>
<target android:name="path">
<aapt:attr name="android:animation">
<objectAnimator
android:propertyName="pathData"
android:duration="1000"
android:valueFrom="M 6 6 L 74 6"
android:valueTo="M 6 6 L 1 6"
android:valueType="pathType"
android:interpolator="#android:anim/linear_interpolator"/>
</aapt:attr>
</target>
My activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ImageView
android:id="#+id/object"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginBottom="8dp"
android:src="#drawable/avd_anim"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
and finally my MainActivity.class
public class MainActivity extends AppCompatActivity {
private ImageView image;
private AnimatedVectorDrawable animation;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image = (ImageView) findViewById(R.id.object);
}
#Override
protected void onStart() {
super.onStart();
Drawable d = image.getDrawable();
if (d instanceof AnimatedVectorDrawable) {
Log.d("testanim", "onCreate: instancefound" + d.toString());
animation = (AnimatedVectorDrawable) d;
animation.start();
}
}
}
You should use redot.getDrawable() instead of getBackground()
And if you are using app:srcCompat="#drawable/..." instead of android:src=#drawable/... for ImageView you should add
if (d instanceof AnimatedVectorDrawableCompat) {
AnimatedVectorDrawableCompat avd = (AnimatedVectorDrawableCompat) d;
avd.start();
}
And android:animation="#anim/redanim" should be android:animation="#animator/redanim". Use animator folder

Android FloatingActionButton Speed Dial

I am currently working on an Android app in which I use a FloatingActionButton. I would like to use the speed dial to have multiple actions that spin/jump out of the action button as described in this page by Google on Android design, or as could be seen in an earlier version of the Keep app (sorry, but I can only post one link). I am using the Android Design Support library specifically version 23.1.1 (com.android.support:design:23.1.1). I already searched using Google and looked at the reference for the FloatingActionButton but couldn't find anything concerning the speed dial.
I would like to know if there is a way to easily achieve this using the default FloatingActionButton, or if I have to program all transitions/animations manually?
Additionally I would like to have little labels next to the buttons, describing the action, if possible.
Thank you in advance!
I'm here to add my 2 cents because this is where I landed after Googling for that exact title.
I hope it doesn't come too late to help someone like me.
First off, the solution comes from here, so is not mine. I just tried and it works nicely. So i thought i share with you in a single post rather have you go dig the code up from there.
The solution uses com.android.support:design:25.3.1 library so be sure to add that to build.gradle and it requires API 21 onwards.
The bad news is that it is composed from several small moving parts: 5 animators, 5 drawables plus the icons and layouts and of course, the code, the good news is that it works as it should, is highly customizable and doesn't require any coding outside MainActivity.
Some notes:
The big fab's image morphs between more and minus signs and rotates when tapped.
Buttons can have text, provided you put both the text and each small fab inside a LineaLayout and move the button id to the LinearLayout so it gets animated instead of the fab, but it requires code to hide and show the text when necessary.
This is the result:
So, the ingredients:
Drawables (res/drawable/).

android:contentDescription="#null"
android:visibility="visible"
android:layout_marginTop="8dp" />
</RelativeLayout>
</merge>
And lastly.
The code (java//MainActivity.java)
a) Some declarations:
private static final String TAG = "Floating Action Button";
private static final String TRANSLATION_Y = "translationY";
private ImageButton fab;
private boolean expanded = false;
private View fabAction1;
private View fabAction2;
private View fabAction3;
private float offset1;
private float offset2;
private float offset3;
b) Delete the usual fab code on MainActivity's onCreate:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
and replace it with:
final ViewGroup fabContainer = (ViewGroup) findViewById(R.id.fab_container);
fab = (ImageButton) findViewById(R.id.fab);
fabAction1 = findViewById(R.id.fab_action_1);
// insert onClickListener here
fabAction2 = findViewById(R.id.fab_action_2);
// insert onClickListener here
fabAction3 = findViewById(R.id.fab_action_3);
// insert onClickListener here
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
expanded = !expanded;
if (expanded) {
expandFab();
} else {
collapseFab();
}
}
});
fabContainer.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
#Override
public boolean onPreDraw() {
fabContainer.getViewTreeObserver().removeOnPreDrawListener(this);
offset1 = fab.getY() - fabAction1.getY();
fabAction1.setTranslationY(offset1);
offset2 = fab.getY() - fabAction2.getY();
fabAction2.setTranslationY(offset2);
offset3 = fab.getY() - fabAction3.getY();
fabAction3.setTranslationY(offset3);
return true;
}
});
c) Add supporting functions on MainActivity (animation code mostly and the 3 small fab's onClick methods):
private void collapseFab() {
fab.setImageResource(R.drawable.animated_minus);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(createCollapseAnimator(fabAction1, offset1),
createCollapseAnimator(fabAction2, offset2),
createCollapseAnimator(fabAction3, offset3));
animatorSet.start();
animateFab();
}
private void expandFab() {
fab.setImageResource(R.drawable.animated_plus);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(createExpandAnimator(fabAction1, offset1),
createExpandAnimator(fabAction2, offset2),
createExpandAnimator(fabAction3, offset3));
animatorSet.start();
animateFab();
}
private Animator createCollapseAnimator(View view, float offset) {
return ObjectAnimator.ofFloat(view, TRANSLATION_Y, 0, offset)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}
private Animator createExpandAnimator(View view, float offset) {
return ObjectAnimator.ofFloat(view, TRANSLATION_Y, offset, 0)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}
private void animateFab() {
Drawable drawable = fab.getDrawable();
if (drawable instanceof Animatable) {
((Animatable) drawable).start();
}
}
public void fabAction1(View view) {
Log.d(TAG, "Action 1");
Toast.makeText(this, "Go shopping!", Toast.LENGTH_SHORT).show();
}
public void fabAction2(View view) {
Log.d(TAG, "Action 2");
Toast.makeText(this, "Gimme money!", Toast.LENGTH_SHORT).show();
}
public void fabAction3(View view) {
Log.d(TAG, "Action 3");
Toast.makeText(this, "Turn it up!", Toast.LENGTH_SHORT).show();
}
d) Reference the fab.xml layout from res/layout/activity_main.xml
Delete the fab declaration:
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#android:drawable/ic_dialog_email" />
Replace with:
<include layout="#layout/fab" />
Last notes:
Feel free to scrap the onClick code for the fabs and replace it with
onClickListener. Those should go right where the comment that says
// insert onClickListener here. Just remember to delete the
onClick attribute for each fab in fab.xml file and get rid of
the last 3 functions in MainActivity (fabAction1, fabAction2
and fabAction3).
Most measures, dimensions, etc. I put them right in the code to avoid including even more files.
The code is not optimized on changed in any way.
I hope this helps someone and sorry for the wall of text.
I would like to know if there is a way to easily achieve this using the default FloatingActionButton
FAB from Design Library does not have this feature. You need to look for 3rd party FABs (there's a few on android-arsenal to choose from)
This library is implementing the Speed Dial from the Material Design guidelines:
https://github.com/leinardi/FloatingActionButtonSpeedDial

rotate fab and pre-5.0 the fab‘s shadow is cliped

origin image
rotate FAB and the shadow is clipped
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/overshoot_interpolator"
android:duration="300"
android:propertyName="rotation"
android:valueFrom="135f"
android:valueTo="0f" >
</objectAnimator>
the first animator
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/overshoot_interpolator"
android:duration="300"
android:propertyName="rotation"
android:valueFrom="0f"
android:valueTo="135f" >
</objectAnimator>
the second animator
mExpandMenuAnimator = (ObjectAnimator)AnimatorInflater.loadAnimator(this,R.animator.fab_clockwise_animator);
mCollapsedMenuAnimator = (ObjectAnimator) AnimatorInflater.loadAnimator(this,R.animator.fab_anticlockwise_animator);
mFab = (FloatingActionButton)findViewById(R.id.home_fab);
mExpandMenuAnimator.setTarget(mFab);
mCollapsedMenuAnimator.setTarget(mFab);
mFab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (i == 0){
i = 1;
mCollapsedMenuAnimator.start();
}else{
i = 0;
mExpandMenuAnimator.start();
}
}
});
FAB is support lib FAB, and how to solove the shadow clipped problem,
or just rotate the src drawable doesn't rotate all of FAB, but how to do it?

How to animate button in android?

I am making an android app, and I have a button which leads to a messaging place. On the activity with the button, I check if there is any unread messages, and if so I want to do something to the button to let the user know that there is something unread.
I was thinking of having the button sorta vibrate horizontally like 3 shakes every 2 or 3 seconds.
I know how to run a thread in the background which does something every x milliseconds. But what I don't know what to do is shake it horizontally 3 times.
Can anyone help with this?
I was thinking of using the sin function, for the animation, I can use output from a sin function to get values that go up and down, which I can set the horizontal position of the button... But this seems too extreme, is there a better way?
I can't comment on #omega's comment because I don't have enough reputation but the answer to that question should be something like:
shake.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="100" <!-- how long the animation lasts -->
android:fromDegrees="-5" <!-- how far to swing left -->
android:pivotX="50%" <!-- pivot from horizontal center -->
android:pivotY="50%" <!-- pivot from vertical center -->
android:repeatCount="10" <!-- how many times to swing back and forth -->
android:repeatMode="reverse" <!-- to make the animation go the other way -->
android:toDegrees="5" /> <!-- how far to swing right -->
Class.java
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
view.startAnimation(shake);
This is just one way of doing what you want, there may be better methods out there.
create shake.xml in anim folder
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0"
android:toXDelta="10"
android:duration="1000"
android:interpolator="#anim/cycle" />
and cycle.xml in anim folder
<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
android:cycles="4" />
now add animation on your code
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);
If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value
Class.Java
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_with_the_button);
final Animation myAnim = AnimationUtils.loadAnimation(this, R.anim.milkshake);
Button myButton = (Button) findViewById(R.id.new_game_btn);
myButton.setAnimation(myAnim);
}
For onClick of the Button
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.startAnimation(myAnim);
}
});
Create the anim folder in res directory
Right click on, res -> New -> Directory
Name the new Directory anim
create a new xml file name it milkshake
milkshake.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="100"
android:fromDegrees="-5"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="10"
android:repeatMode="reverse"
android:toDegrees="5" />
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Transformation;
public class HeightAnimation extends Animation {
protected final int originalHeight;
protected final View view;
protected float perValue;
public HeightAnimation(View view, int fromHeight, int toHeight) {
this.view = view;
this.originalHeight = fromHeight;
this.perValue = (toHeight - fromHeight);
}
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
view.getLayoutParams().height = (int) (originalHeight + perValue * interpolatedTime);
view.requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
}
uss to:
HeightAnimation heightAnim = new HeightAnimation(view, view.getHeight(), viewPager.getHeight() - otherView.getHeight());
heightAnim.setDuration(1000);
view.startAnimation(heightAnim);
Dependency
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}}
and then add dependency
dependencies {
compile 'com.github.varunest:sparkbutton:1.0.5'
}
Usage
XML
<com.varunest.sparkbutton.SparkButton
android:id="#+id/spark_button"
android:layout_width="40dp"
android:layout_height="40dp"
app:sparkbutton_activeImage="#drawable/active_image"
app:sparkbutton_inActiveImage="#drawable/inactive_image"
app:sparkbutton_iconSize="40dp"
app:sparkbutton_primaryColor="#color/primary_color"
app:sparkbutton_secondaryColor="#color/secondary_color" />
Java (Optional)
SparkButton button = new SparkButtonBuilder(context)
.setActiveImage(R.drawable.active_image)
.setInActiveImage(R.drawable.inactive_image)
.setDisabledImage(R.drawable.disabled_image)
.setImageSizePx(getResources().getDimensionPixelOffset(R.dimen.button_size))
.setPrimaryColor(ContextCompat.getColor(context, R.color.primary_color))
.setSecondaryColor(ContextCompat.getColor(context, R.color.secondary_color))
.build();
In Kotlin, this way after XML:
Define a View:
val playDel = findViewById<ImageView>(R.id.player_del)
Find a Animation: Here from Android Lib
val imgAnim = AnimationUtils.loadAnimation(this, android.R.anim.fade_out)
Connect to the View
playDel.animation=imgAnim
First create shake.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="100"
android:fromDegrees="-5"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="10"
android:repeatMode="reverse"
android:toDegrees="5" />
Class.java
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
view.startAnimation(shake);
