I can rotate my image infinitely. But my problem is that the image pauses shortly when it reaches 360º and then starts rotating again. It happens the same even when I applied "linear_interpolator".
What I want to do is that the image does not pause at all when it starts the next round. So it has to rotate infinitely with same speed at any degree.
Here is my - code. Thanks
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<rotate
android:interpolator="#android:anim/linear_interpolator"
android:duration="1400"
android:pivotX="50%"
android:pivotY="50%"
android:fromDegrees="0"
android:toDegrees="360"
android:repeatMode="restart"
android:repeatCount="infinite" />
</set>
How I call it on my code
rotate= AnimationUtils.loadAnimation(context, R.anim.loop_rotate)
binding.imgSecondLayout.startAnimation(rotate)
Thanks for help! :)
Add animation.setRepeatCount(Animation.INFINITE) to your java class where animation is called.
My final code is given here:
Animation animation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.loop_rotate);
animation.setInterpolator(new LinearInterpolator());
animation.setRepeatCount(Animation.INFINITE);
animation.setDuration(1400);
youractivity.startAnimation(animation);
This is due to the small delay after the animation completes its duration (1400 ms in ur case). you can remove this delay for smooth animation.
Remove repeatMode attribute and instead add this line :
android:startOffset="0" //Delay in milliseconds before the animation runs
The animation will be smooth without any delays

I want to rotate an Image in a slow way on Android.
I can do this by creating a Bitmap and by the
help of of Matrix class. But i don't know how to make it slow, like it should take 3 seconds to rotate.
Rotate
Rotate animation uses tag. For rotate animation required tags are android:fromDegrees and android:toDegrees which defines rotation angles.
Clock wise – use positive toDegrees value
Anti clock wise – use negative toDegrees value
rotate.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<rotate android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="600"
android:repeatMode="restart"
android:repeatCount="infinite"
android:interpolator="#android:anim/cycle_interpolator"/>
</set>
Save in anim folder
public class AnimationActivity extends Activity{
ImageView img;
Animation rotate;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fadein);
img = (ImageView) findViewById(R.id.myimageid);
// load the animation
rotate = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.rotate);
img.startAnimation(rotate);
}
}

In Kotlin you can use the ObjectAnimator do this super easily. For example:
ObjectAnimator.ofFloat(view, "rotationX", 180f).apply {
duration = 2000
start()
}
view: the view you want to rotate
"rotationX": the propertyName you want to alter.
"rotationX" gives you rotation into and out of the screen
"rotationY" gives you clockwise/counterclockwise rotation
180f: how many degrees you want to rotate the view
duration: the number of milliseconds the animation should take to complete
You can use rotate animation to achieve this.
Create anim folder under res directoy inside that place this xml.
rotate_around_center_point.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<rotate
android:duration="2500"
android:interpolator="#android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:repeatMode="restart"
android:toDegrees="360" />
</set>
Set animation to view like this.
ImageView animationTarget = (ImageView) this.findViewById(R.id.testImage);
Animation animation = AnimationUtils.loadAnimation(this, R.anim.rotate_around_center_point);
animationTarget.startAnimation(animation);
Hi guys i uses the code below to perform rotation but it only rotates one time and goes back to its original position, how to let the image stay at the rotated position?
<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="90"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1000"
android:startOffset="0"
/>
xml file of my code
Animation rotation = AnimationUtils.loadAnimation(this, R.anim.rotate);
a.startAnimation(rotation);
use:
anim.setFillAfter(true);
If fillAfter is true, the transformation that this animation performed
will persist when it is finished. Defaults to false if not set. Note
that this applies to individual animations and when using an
AnimationSet to chain animations.
I have a music app and the music notations perform an animation from right to left, I want to control the animation speed, while they are performing.Can anyone please help me for that?
My animation layout is:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="500%" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="10000"
android:fillAfter="true"
android:repeatCount="infinite"/>
And my code to perform the animation is:
Animation am=AnimationUtils.loadAnimation(this, R.anim.note);
music1.startAnimation(am);
set your android:duration with this help you can control your animation speed
android:duration="300"
change in the duration will control the speed of animation in your file.
android:duration="10000" // here you have to change the time in milliseconds.
you can implement onTouchListener to control your animation speed at the run time. inside touch listener event put coding to change your animation duration.
From official documentation:
ValueAnimator animation = ValueAnimator.ofFloat(0f, 100f);
animation.setDuration(1000);
animation.start()
In your case:
music.setDuration(setValue);
I have an ImageView that should rotate for 4 times. This is my xml of animation:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromDegrees="0"
android:interpolator="#android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="3"
android:repeatMode="restart"
android:toDegrees="360" />
but rotation is not fluid: there's a little delay from end of a rotation, and begin of next one. How can i fix it?
Try to rotate from 0 to 359. 0 and 360 is the same in that context.
why not create an animation the usual way, and if you want it to rotate four times, then create a loop that iterates four times, and for each iteration, it calls the animation. You have to optimize your code so that are no visible drags.
I want to rotate an image in my application in such a manner that it rotate like a simple pendulam and will stop after some time.
How I can achieve it using View Animation or Property Animation in android
I used the below xml for the animation
<rotate
android:duration="2000"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:fromDegrees="-15"
android:pivotX="50%"
android:pivotY="0%"
android:repeatCount="5"
android:repeatMode="reverse"
android:toDegrees="15" />
And below is the code for the animation
Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this,
R.anim.rotate);
firstBell.startAnimation(hyperspaceJumpAnimation);
But the problem is when animation starts it suddenly move to angle -15 and then start animating. And it stops after 5 count suddenly not in smooth way.
So my question is how to resolve this issue
Looking for help.
About -15 degree:
android:fromDegrees="-15"
and
android:toDegrees="15"
These two lines mean your object start from -15 degrees and end with 15 degree. If that are not what you want, just delete them.
For the Smooth way, you may find the fade.xml in your ApiDemo/res/anim folder.
