今天看到了一个点赞的效果，感觉还不错！于是抄袭了下来！
其实它就是一个PopupWindow,点击后显示，然后做了上移和变淡的效果，最后消失！
抄袭地址GoodView

其实主要的代码就一个继承类，和一个控制常量的接口

- 常量接口
package com.smallcake.utils.popup;
import android.graphics.Color;
/**
* 常量控制
*/
public interface IGoodView {
int DISTANCE = 60; // 默认移动距离
int FROM_Y_DELTA = 0; // Y轴移动起始偏移量
int TO_Y_DELTA = DISTANCE; // Y轴移动最终偏移量
float FROM_ALPHA = 1.0f; // 起始时透明度
float TO_ALPHA = 0.0f; // 结束时透明度
int DURATION = 1000; // 动画时长
String TEXT = ""; // 默认文本
int TEXT_SIZE = 16; // 默认文本字体大小
int TEXT_COLOR = Color.BLACK; // 默认文本字体颜色
}
