平移（TranslatAnimation）

注意：平移后会回到原位，所以要添加最后一句setY。但是这里的值和平移的Y又不同。

    private void win(ImageView child){
        //向上爬动态
        Animation translationAnimation=new TranslateAnimation(0,0,0,-12);
        translationAnimation.setDuration(500);//设置持续时间
        child.startAnimation(translationAnimation);
        child.setY(child.getY()-90);
    }

效果：

 

 

 

 

旋转（RotateAnimation）

public void run2(ImageView cat){                         
       //旋转
        Animation rotateAn =new RotateAnimation(-5, 5, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        rotateAn.setDuration(1000);//设置持续时间
        rotateAn.setRepeatCount(12);
        cat.startAnimation(rotateAn);
    }

AnimationSet 

xml：（正常设置即可）

java：

核心代码：

Animation rotateAn =new RotateAnimation(-5, 5, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); //旋转-5°~+5°，0.5f代表50%，中心位置为原点

AnimationSet st = new AnimationSet(true);
st.addAnimation(rotateAn);
Animation translationAnimation=new TranslateAnimation(-200,2500,0,0);  //平移
st.addAnimation(translationAnimation);
cat.startAnimation(st);

public void run2(ImageView cat){                         //小猫旋转+平移
       //旋转
        Animation rotateAn =new RotateAnimation(-5, 5, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        rotateAn.setDuration(1000);//设置持续时间
        rotateAn.setRepeatCount(12);
        //集
        AnimationSet st = new AnimationSet(true);
        st.addAnimation(rotateAn);
        //平移
        Animation translationAnimation=new TranslateAnimation(-200,2500,0,0);
        translationAnimation.setDuration(12000);//设置持续时间
        st.addAnimation(translationAnimation);
        cat.startAnimation(st);
    }

效果：（一边旋转一边移动）
