android 点赞动画效果,Android点赞效果

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

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

}
