Implement color animation with ValueAnimator

To implement color animation with ValueAnimator:

package com.example.valueanimatorofcolor;

import com.example.objectanimatorofargb.R;

import android.animation.ArgbEvaluator;
import android.animation.ObjectAnimator;
import android.animation.ValueAnimator;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {

 TextView title;
 Button btnStart;
 ImageView image;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  title = (TextView) findViewById(R.id.title);
  image = (ImageView) findViewById(R.id.image);
  btnStart = (Button) findViewById(R.id.start);
  
  btnStart.setOnClickListener(new OnClickListener(){

   @Override
   public void onClick(View v) {
    startColorAnimation(image);
   }});
 }
 
 private void startColorAnimation(View view){
  //int colorStart = 0xFFffffff;
  int colorStart = view.getSolidColor();
  int colorEnd   = 0xFF000000;

  ValueAnimator colorAnim = ObjectAnimator.ofInt(
    view, "backgroundColor", colorStart, colorEnd);
  colorAnim.setDuration(2000);
  colorAnim.setEvaluator(new ArgbEvaluator());
  colorAnim.setRepeatCount(1);
  colorAnim.setRepeatMode(ValueAnimator.REVERSE);
  colorAnim.start();
 }

}
