public class StackOverflowActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ImageView iv_icon = (ImageView) findViewById(R.id.imageView1);

    Animation a = AnimationUtils.loadAnimation(this, R.anim.anim_img);
    a.setFillAfter(true);
    a.reset();

    iv_icon.startAnimation(a);
}
}

and the animatin xml is anim_img.xml,

<?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="358" />
