动画工具类

package com.example.uumusic.utils;

import android.animation.ObjectAnimator;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.RotateAnimation;
import android.widget.RelativeLayout;

/**
* Created by Administrator on 2017.06.07.0007.
*/
public class Tools {

//隐藏布局
public static void hide(ViewGroup view) {
hide(view, 0);
}

//显示布局
public static void show(ViewGroup view) {

//使用属性动画实现菜单的旋转
ObjectAnimator animator = ObjectAnimator.ofFloat(view,"rotation",180,360);
//设置动画时长
animator.setDuration(300);
animator.start();
view.setPivotX(view.getWidth()/2);
view.setPivotY(view.getHeight());
}

//延迟隐藏
public static void hide(ViewGroup view, int i) {
ObjectAnimator animator = ObjectAnimator.ofFloat(view,"rotation",0,180);
//设置动画时长
animator.setDuration(300);
//设置延迟
animator.setStartDelay(i);
animator.start();
view.setPivotX(view.getWidth()/2);
view.setPivotY(view.getHeight());
}
}
