1.layout改变实现动态（4次移动位置循环组成）：

核心代码： 

public void run() {
        RelativeLayout.LayoutParams temp = (RelativeLayout.LayoutParams) cat.getLayoutParams();
        temp.setMargins(0,270,0,0);
        cat.setRotation(10);
        cat.setLayoutParams(temp);
    }
}, t);

整个代码： 

public void keepRun(ImageView cat){
        int t = 0;
        for(int i=0;i<50;i++){
            run(cat,t);
            t+=800;
        }
    }
    public void run(ImageView cat,int t){
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                RelativeLayout.LayoutParams temp = (RelativeLayout.LayoutParams) cat.getLayoutParams();
                temp.setMargins(0,270,0,0);
                cat.setRotation(10);
                cat.setLayoutParams(temp);
            }
        }, t);
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                RelativeLayout.LayoutParams temp = (RelativeLayout.LayoutParams) cat.getLayoutParams();
                temp.setMargins(0,270,0,0);
                cat.setLayoutParams(temp);
                cat.setRotation(0);
            }
        }, t+=200);//0.1秒后执行Runnable中的run方法
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                RelativeLayout.LayoutParams temp = (RelativeLayout.LayoutParams) cat.getLayoutParams();
                temp.setMargins(0,200,0,0);
                cat.setRotation(-10);
                cat.setLayoutParams(temp);
            }
        }, t+=200);//0.1秒后执行Runnable中的run方法
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                RelativeLayout.LayoutParams temp = (RelativeLayout.LayoutParams) cat.getLayoutParams();
                temp.setMargins(0,200,0,0);
                cat.setLayoutParams(temp);
                cat.setRotation(0);
            }
        }, t+=200);//0.1秒后执行Runnable中的run方法
    }

 2. 平移实现动态

Android Studio||动态改变xml图片位置/旋转+平移/AnimationSet_bdy_y9的博客-CSDN博客这里写目录标题帧动画FrameAnimation补间动画TweenAnimationTranslatAnimation：平移动画ScaleAnimation：缩放动画alphaAnimation：淡出动画rotateAnimation：旋转动画setAnimation :动画集，可以包含多个动画Animator（属性动画）：真正改变了动画的属性常见属性ValueAnimator：值动画PropertyValueHolder：多个动画同时执行帧动画FrameAnimation按字面理解，就是将多个图片连续。https://blog.csdn.net/weixin_51159944/article/details/129842687?spm=1001.2014.3001.5501

3.图片翻转对称

android:scaleX="-1"

//水平翻转
