Answer 1

Make anim folder then create rotate xml file

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><rotate
    android:duration="1500"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="720" /></set>

Apply on Image

 final ImageView rotate = (ImageView) findViewById(R.id.lolo);
    final Animation rotateAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate);
    rotate.startAnimation(rotateAnimation);

Answer 2

I managed to solve the problem. Resolution below.

Animation a = new RotateAnimation(0.0f, 360.0f,
            Animation.RELATIVE_TO_SELF, 0.34f, Animation.RELATIVE_TO_SELF,
            0.67f);
    this.startAnimation(a);
    a.setRepeatCount(-1);
    a.setDuration(680);

Xml

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center">

    <Imageview
        android:layout_width="35dp"
        android:layout_height="35dp"
        app:typeSpinner="default-spinner" />

</LinearLayout>

Result
