2 |
3 | 幸运转盘，可以控制选中指定的奖项。如下图，选择 ID 为 6 的奖项，在转盘停止后，选中 ID 为 6 的奖项。
4 |
5 | [demo下载](https://raw.githubusercontent.com/Bakumon/LuckPan/master/apk/app-debug.apk)
6 |
7 | 
8 |
9 | 最近项目中用到了转盘抽奖，才知道抽奖原来这么坑，转盘转动只是给用户看看而已。和点击按钮直接显示出抽奖结果的区别就是等、等、等，看着转盘揪心。
10 |
11 | 需求：
12 |
13 | 1. 转盘上奖项的个数以及奖项的值通过调用接口确定
14 | 2. 点击“开始抽奖”按钮，调接口成功后，停在接口返回的指定位置
15 |
16 | API:
17 |
18 | | 方法 | 参数 | 说明 |
19 | | :-------------|:-------------| :-----|
20 | | setPrizeVoList(List\) | PrizeVo 实体集合，PrizeVo 实体包含 ID、title 等属性 | (必须)设置奖项集合 |
21 | | setDarkColor(int) | 颜色，如 Color.rgb(82, 182, 197) | (非必须,有默认)设置转盘上的深色 |
22 | | setShallowColor(int) | 颜色，如 Color.rgb(186, 226, 232) | (非必须,有默认)设置转盘上的浅色色 |
23 | | setCircleNumRange(int, int) | 转动圈数的范围，如 9～15 | (非必须,有默认)设置转动圈数的范围 |
24 | | setOneCircleMillisRange(long, long) | 每圈平均用时毫秒数的范围，如 400～600 | (非必须,有默认)设置平均转动一圈用时的范围 |
25 | | setOnLuckPanAnimatorEndListener(listener) | 转盘停止监听器 | (非必须)设置转盘停止监听器 |
26 | | start(int) | 选中奖项的 ID | (必须)转盘开始转动，并停在 ID 值对应的位置上 |
27 |
28 | ## 使用
29 |
30 | 1.得到奖项数据集合
31 |
32 | ```java
33 | List prizeVoList = new ArrayList<>();
34 | PrizeVo prizeVo;
35 | for (int i = 0; i < 16; i++) {
36 | prizeVo = new PrizeVo();
37 | prizeVo.id = i + "";
38 | prizeVo.rate = i + "";
39 | prizeVo.title = "×" + i;
40 | prizeVoList.add(prizeVo);
41 | }
42 | ```
43 |
44 | 2.转盘设置奖项数据
45 |
46 | ```java
47 | // 转盘设置奖项集合
48 | mLuckPan.setPrizeVoList(prizeVoList);
49 | ```
50 |
51 | 3.开始转动
52 |
53 | ```java
54 | // 转到 ID 为 3 的奖项停止
55 | mLuckPan.start(3);
56 | ```
57 |
58 | 可选：设置转动停止监听器
59 |
60 | ```java
61 | mLuckPan.setOnLuckPanAnimatorEndListener(new LuckPan.OnLuckPanAnimatorEndListener() {
62 | @Override
63 | public void onLuckPanAnimatorEnd(PrizeVo choicePrizeVo) {
64 | Toast.makeText(MainActivity.this, "选中的ID：" + choicePrizeVo.id, Toast.LENGTH_SHORT).show();
65 | }
66 | });
67 | ```
