组件由原始状态向终极状态转变时,为了让过渡更自然,而自动生成的动画
TranslateAnimation ta = new TranslateAnimation(10, 100, 20, 200);
10:表示的x坐标起始位置
100:表示x坐标的结束位置
20:表示y坐标的起始位置
200:表示y坐标的结束位置
iv的真实y + 200
TranslateAnimation ta = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 1, Animation.RELATIVE_TO_SELF, 3, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 2);
Animation.RELATIVE_TO_SELF, 1:x坐标的初始位置
Animation.RELATIVE_TO_SELF, 0.5f:y坐标的起始位置
ScaleAnimation sa = new ScaleAnimation(0.5f, 2, 0.1f, 3, iv.getWidth() / 2, iv.getHeight() / 2);
iv.getWidth() / 2:表示缩放点的x坐标
iv的真实x + iv.getWidth() / 2
ScaleAnimation sa = new ScaleAnimation(0.5f, 2, 0.1f, 3, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

一张张图片不断的切换,形成动画效果
在drawable目录下定义xml文件,子节点为animation-list,在这里定义要显示的图片和每张图片的显示时长
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:drawable="@drawable/g1" android:duration="200" />
<item android:drawable="@drawable/g2" android:duration="200" />
<item android:drawable="@drawable/g3" android:duration="200" />
</animation-list>
在屏幕上播放帧动画
ImageView iv = (ImageView) findViewById(R.id.iv);
//把动画文件设置为imageView的背景
iv.setBackgroundResource(R.drawable.animations);
AnimationDrawable ad = (AnimationDrawable) iv.getBackground();
//播放动画
ad.start();
参数150指的是X的终点坐标,它的值是imageview的 真实X + 150
//创建为位移动画对象,设置动画的初始位置和结束位置
TranslateAnimation ta = new TranslateAnimation(10, 150, 20, 140);
y坐标的终点位置,如果传入2,那么终点坐标就是 真实Y + 2 * iv高度
TranslateAnimation ta = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 2, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 2);
动画播放相关的设置
//设置动画持续时间
ta.setDuration(2000);
//动画重复播放的次数
ta.setRepeatCount(1);
//动画重复播放的模式
ta.setRepeatMode(Animation.REVERSE);
//动画播放完毕后,组件停留在动画结束的位置上
ta.setFillAfter(true);
//播放动画
iv.startAnimation(ta);
缩放的中心点在iv左上角
ScaleAnimation sa = new ScaleAnimation(0.1f, 4, 0.1f, 4);
中心点Y坐标 = 真实Y + 0.5 * iv高度
ScaleAnimation sa = new ScaleAnimation(0.1f, 4, 0.1f, 4, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
0为完全透明,1为完全不透明
AlphaAnimation aa = new AlphaAnimation(0, 0.5f);
默认旋转的圆心在iv左上角
RotateAnimation ra = new RotateAnimation(20, 360);
圆心的Y坐标:真实Y + iv高度 * 0.5
RotateAnimation ra = new RotateAnimation(20, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
//创建动画集合
AnimationSet set = new AnimationSet(false);
//往集合中添加动画
set.addAnimation(aa);
set.addAnimation(sa);
set.addAnimation(ra);
iv.startAnimation(set);
传入100,代表x终点坐标:当前x + 100
//具有get、set方法的成员变量就称为属性
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "translationX", 0, 100) ;
2是到原本高度的2倍结束
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "scaleY", 0.1f, 2);
透明度,0是完全透明,1是完全不透明
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "alpha", 0.1f, 1);
270是结束角度
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "rotation", 20, 270);
属性指定为rotationY是水平翻转
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "rotationY", 20, 180);
第三个参数可变参数可以传入多个参数,可以实现往回位移(旋转、缩放、透明)
ObjectAnimator oa = ObjectAnimator.ofFloat(bt, "translationX", 0, 70, 30, 100) ;
//创建动画师集合
AnimatorSet set = new AnimatorSet();
//设置要播放动画的组件
set.setTarget(bt);
//所有动画有先后顺序的播放
//set.playSequentially(oa, oa2, oa3, oa4);
//所有动画一起播放
set.playTogether(oa, oa2, oa3, oa4);
set.start();
