Android中的属性动画（一般属性动画，组合属性动画，AnimatorSet，动画监听）

public void Click(View view){
//f是float类型
ObjectAnimator.ofFloat(view, "retainX", 0.0f,360.0f).setDuration(500).start();
}

public void doclickt(View view){
PropertyValuesHolder pl=PropertyValuesHolder.ofFloat("alpha", 1f,0f,1f);
PropertyValuesHolder p2=PropertyValuesHolder.ofFloat("sclatex", 1f,0f,1f);
ObjectAnimator.ofPropertyValuesHolder(view, pl,p2).setDuration(500).start();
}

ObjectAnimator a1=ObjectAnimator.ofFloat(view, "translationX", 0f,200f);
ObjectAnimator a2=ObjectAnimator.ofFloat(view, "translationY", 0f,200f);
ObjectAnimator a3=ObjectAnimator.ofFloat(view, "translation", 0f,200f);
AnimatorSet set=new AnimatorSet();
set.setDuration(100);
//set.playTogether(a1,a2,a3);//同时执行
//set.setStartDelay(100);//延迟执行
//set.playSequentially(a1,a2,a3);//顺序执行
set.play(a1).with(a2);//a1,a2同时执行，之后执行a3
set.play(a3).after(a2);
set.start();

public  void startAnimtor(View view){
ObjectAnimator animator = ObjectAnimator.ofFloat(view, "alpha", 1f,0f).setDuration(100);
animator.addListener(new AnimatorListener() {

@Override
public void onAnimationStart(Animator arg0) {
// 开始动画

}

@Override
public void onAnimationRepeat(Animator arg0) {
// 重复动画

}

@Override
public void onAnimationEnd(Animator arg0) {
// 结束动画

}

@Override
public void onAnimationCancel(Animator arg0) {
// 取消动画

}
});
animator.start();
animator.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
// TODO Auto-generated method stub
super.onAnimationEnd(animation);
}
});
animator.start();
}

public void onClick(View view){
final View v=view;
DisplayMetrics bm=new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(bm);

//自由落体（第一个参数是起点，第二个是运动到的位置，第三是返回原位（不写下去就不上来领））
ValueAnimator duration = ValueAnimator.ofFloat(view.getY(),bm.heightPixels,v.getY()).setDuration(500);
//监听动画的每个动作
duration.addUpdateListener(new AnimatorUpdateListener() {

@Override
public void onAnimationUpdate(ValueAnimator an) {
// TODO Auto-generated method stub
v.setTranslationY((Float) an.getAnimatedValue());
}
});
duration.start();
