How to change the speed of ProgressBar in Android using Java?

Question

I have a ProgressBar (the round shape one) and it spins very fast, how do I change it to spin at a slower speed?

(It is running indefinitely)

Here is my XML of ProgressBar:

<ProgressBar
        android:id="@+id/progressBar"
        style="@style/Widget.AppCompat.ProgressBar"
        android:layout_width="409dp"
        android:layout_height="710dp"
        android:indeterminate="false"
        android:padding="36dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

you can change interpolator to ease-in or slow-in slow out or something else it won't change speed but will make it look better in many ways — trinadh thatakula

Add a .xml file under /drawable path, like: drawable/circular_spinner.xml circular_spinner:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner"
    android:interpolator="@android:anim/linear_interpolator"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:toDegrees="3600"
    android:duration="1000"/>

Change the toDegrees and duration to control the speed of the spinning. Then call it in your progressbar layout.

<ProgressBar
        android:id="@+id/progressBar"
        style="@style/Widget.AppCompat.ProgressBar"
        android:layout_width="409dp"
        android:layout_height="710dp"
        android:indeterminate="false"
        android:padding="36dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        android:indeterminateDrawable="@drawable/circular_spinner"
        app:layout_constraintTop_toTopOf="parent"/>

See also change ProgressBar fps in Android:

<ProgressBar
    android:indeterminateDuration="1000"

Old answer <rotate android:duration="1000"/> doesn't work now.
