答案可以从很多方面给出。你也可以使用ValueAnimator的ofArgb(startColor,endColor)。

火灾> 21:

int cyanColorBg = ContextCompat.getColor(this,R.color.cyan_bg);
int purpleColorBg = ContextCompat.getColor(this,R.color.purple_bg);

ValueAnimator valueAnimator = ValueAnimator.ofArgb(cyanColorBg,purpleColorBg);
        valueAnimator.setDuration(500);
        valueAnimator.setInterpolator(new LinearInterpolator());
        valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
              @Override
              public void onAnimationUpdate(ValueAnimator valueAnimator) {
                   relativeLayout.setBackgroundColor((Integer)valueAnimator.getAnimatedValue());
              }
        });
        valueAnimator.start();

如果你想要这样的彩色动画，

这段代码将帮助你:

ValueAnimator anim = ValueAnimator.ofFloat(0, 1);   
anim.setDuration(2000);

float[] hsv;
int runColor;
int hue = 0;
hsv = new float[3]; // Transition color
hsv[1] = 1;
hsv[2] = 1;
anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

    @Override
    public void onAnimationUpdate(ValueAnimator animation) {

        hsv[0] = 360 * animation.getAnimatedFraction();

        runColor = Color.HSVToColor(hsv);
        yourView.setBackgroundColor(runColor);
    }
});

anim.setRepeatCount(Animation.INFINITE);

anim.start();

你可以使用API 11上面的ArgbEvaluatorCompat类。

implementation 'com.google.android.material:material:1.0.0' 


ValueAnimator colorAnim = ValueAnimator.ofObject(new ArgbEvaluatorCompat(), startColor, endColor);
colorAnim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            mTargetColor = (int) animation.getAnimatedValue();
        }
    });
colorAnim.start();

最好的方法是使用ValueAnimator和ColorUtils.blendARGB

 ValueAnimator valueAnimator = ValueAnimator.ofFloat(0.0f, 1.0f);
 valueAnimator.setDuration(325);
 valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator valueAnimator) {

              float fractionAnim = (float) valueAnimator.getAnimatedValue();

              view.setBackgroundColor(ColorUtils.blendARGB(Color.parseColor("#FFFFFF")
                                    , Color.parseColor("#000000")
                                    , fractionAnim));
        }
});
valueAnimator.start();

在Kotlin中使用以下函数:

private fun animateColorValue(view: View) {
    val colorAnimation =
        ValueAnimator.ofObject(ArgbEvaluator(), Color.GRAY, Color.CYAN)
    colorAnimation.duration = 500L
    colorAnimation.addUpdateListener { animator -> view.setBackgroundColor(animator.animatedValue as Int) }
    colorAnimation.start()
}

传递任何你想改变颜色的视图。

基于ademar111190的答案，我创建了这个方法，它将在任意两种颜色之间脉冲视图的背景颜色:

private void animateBackground(View view, int colorFrom, int colorTo, int duration) {


    ObjectAnimator objectAnimator = ObjectAnimator.ofObject(view, "backgroundColor", new ArgbEvaluator(), colorFrom, colorTo);
    objectAnimator.setDuration(duration);
    //objectAnimator.setRepeatCount(Animation.INFINITE);
    objectAnimator.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animation) {

        }

        @Override
        public void onAnimationEnd(Animator animation) {
            // Call this method again, but with the two colors switched around.
            animateBackground(view, colorTo, colorFrom, duration);
        }

        @Override
        public void onAnimationCancel(Animator animation) {

        }

        @Override
        public void onAnimationRepeat(Animator animation) {

        }
    });
    objectAnimator.start();
}
