android——ObjectAnimator动画(一)

直接贴上集中用法

package com.example.test;

        move();
    }
    
    public void move(){

        Keyframe kf0 = Keyframe.ofFloat(0f, 0f);
        Keyframe kf1 = Keyframe.ofFloat(.5f, 360f);
        Keyframe kf2 = Keyframe.ofFloat(.2f, 720f);
        PropertyValuesHolder pvhRotation = PropertyValuesHolder.ofKeyframe("rotation", kf0, kf1, kf2);
        ObjectAnimator rotationAnim = ObjectAnimator.ofPropertyValuesHolder(cv, pvhRotation);
        rotationAnim.setDuration(5000);
        rotationAnim.start();
//        ObjectAnimator.ofArgb(cv, ACCESSIBILITY_SERVICE, 244).setDuration(1000).start();
        
    }
