To achieve rotating animations on Android images, you can follow these steps:

  1. Create a folder named “anim” in the “res” directory, and then create an XML file for a rotating animation within that folder, such as “rotate_animation.xml”.
  2. Open the rotate_animation.xml file and define the rotation animation using the following code.
<rotate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:toDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:duration="1000"
    android:repeatCount="infinite" />

The starting and ending angles of the rotation are specified by android:fromDegrees and android:toDegrees, while the center point of the rotation is specified by android:pivotX and android:pivotY. The duration of the rotation is specified by android:duration, and the number of times the rotation will be repeated is specified by android:repeatCount (with “infinite” indicating unlimited repetitions).

  1. To start an animation, such as a rotating animation, in a place where it is needed, such as an ImageView component, use the following code:
ImageView imageView = findViewById(R.id.imageView);
Animation rotateAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate_animation);
imageView.startAnimation(rotateAnimation);

Where R.id.imageView is the ID of the ImageView component to which the rotation animation will be applied.

In this way, when the application is launched, the ImageView component will start rotating according to the rotation animation defined in the rotate_animation.xml file.
