Animation in pictures

Only animate().rotation(angle).start() within the setOnClickListener method of your button would already solve the problem. Thus, it is enough to define a value for the variable angle , which would refer to the desired angle. See:

int angle = 90;
imageView.animate().rotation(angle).start();

1st solution (simple)

In the onClick method of your image, add the following code:

imageView.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        imageView.animate().rotation(90).start();
    }
});

2nd solution (more options)

Create the button_rotate.xml file in the anim folder within your project:

<?xml version="1.0" encoding="utf-8"?>   
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/animation"
    android:duration="1000"
    android:fromDegrees="0"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="90" />

Now create the animation in your Java class, more precisely, within the onClick method of your image:

/* Pega a sua ImageView*/
ImageView iv = (ImageView) view.findViewById(R.id.your_image_view);

/* Cria a animação */
Animation rotation = AnimationUtils.loadAnimation(context, R.anim.animation);
rotation.setRepeatCount(Animation.INFINITE);

/* Inicia a animação */
iv.startAnimation(rotation);

To stop the animation:

iv.clearAnimation();

Translated and adapted from: Rotate image

Use the component's View ## SetRotation () ImageView .

imageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {                  
        imageView.setRotation(90);
    }
});

The 90 can be any value, and if you want to add a rotation, that is, get the current rotation of the view and apply another value, just get the rotation with getRotation and add the its value.

imageView.setRotation(imageView.getRotation() + valor);

If the rotation is 90, the new rotation will be 180, and so on.

Obs : As the author of the post said, this method only applies a rotation in the image, it does not cause an animation in it.

To rotate the image with an animation, you can use the LinearInterpolator

imageView.animate().rotationBy(90).setDuration(300).setInterpolator(new LinearInterpolator()).start();

Where :

• rotationBy (): This is the target rotation of the view, or with what rotation it will stay at the end of the duration.
• setDuration (): As the name says, it is the duration that the rotation will take.
• setInterpolator (): This is basically how the animation will behave.

You can use other attributes, such as withStartAction , as its name says, when the animation starts, it allows you to apply an action in the view, for example, to apply an animation to another view or to itself. >

imageView.animate().rotationBy(90).withStartAction(new Runnable(){
    public void run(){
       imageView.setRotation(90);
    }
}).setDuration(300).setInterpolator(new LinearInterpolator());
