Question

and he is spinning

Update: I am using material progress. But it does not rotate in a certain mode, that I want to rotate at boot time ... just like a telegram application.

Answer 1

Create the rotate.xml file in the res / anim folder:

<?xml version="1.0" encoding="UTF-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1600"
android:fromDegrees="0"
android:interpolator="@android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:toDegrees="360" />

Download the animation and run the code:

view.startAnimation(AnimationUtils.loadAnimation(activity, R.anim.rotate));
