android - I want to use random colors for background with smooth transition effect in loop -

my problem instead of getting random colors @ background getting 2 colors animation effect background. , when restart app 2 color changes. goal there must random colors use background smooth animation of color change here's code

public class mainactivity extends appcompatactivity { int color1,color2;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     final relativelayout targetview = (relativelayout) findviewbyid(r.id.new2);              backgroundpainter backgroundpainter = new backgroundpainter();               color1=getrandcolor();             color2=getrandcolor();             backgroundpainter.animate(targetview, color1, color2);         // int color1 = contextcompat.getcolor(this, r.color.coloraccent);     //int color2 = contextcompat.getcolor(this, r.color.colorprimary);   }      public int getrandcolor(){         random rand = new random();         int r = rand.nextint(255);         int g = rand.nextint(255);         int b = rand.nextint(255);         int rando = color.rgb(r, g, b);         return rando;     }  public class backgroundpainter {      private static final int min = 1800;     private static final int max = 2300;      private final random random;      public backgroundpainter() {         random = new random();      }      public void animate(@nonnull final view target, @colorint final int color1,                         @colorint final int color2) {           final valueanimator valueanimator = valueanimator.ofobject(new argbevaluator(), color1, color2);          valueanimator.setduration(randint(min, max));          valueanimator.addupdatelistener(new valueanimator.animatorupdatelistener() {             @override public void onanimationupdate(valueanimator animation) {                 target.setbackgroundcolor((int) animation.getanimatedvalue());             }         });         valueanimator.addlistener(new animatorlisteneradapter() {             @override public void onanimationend(animator animation) {                 //reverse animation                 animate(target, color2, color1);             }         });          valueanimator.setinterpolator(new acceleratedecelerateinterpolator());         valueanimator.start();     }      private int randint(int min, int max) {         return random.nextint((max - min) + 1) + min;     } } } 

and main xml file

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context="weathercheck.bt4u.com.myapplication.mainactivity" android:id="@+id/screen" android:orientation="horizontal">   </linearlayout> 

just change

animate(target, color2, color1); 

to

animate(target, color2, getrandcolor());
