1 | ## WaveView
2 | ### 简介
3 | 少啰嗦,看东西
4 | 
5 | WaveView 是一个可以高度自定义的波浪控件,能绘制出自己想要的曲线波浪
6 | - 支持设置一个或两个波浪
7 | - 支持分别设置波浪的颜色、振幅、波长、水位线高度、初始偏移量
8 | - 支持分别设置移动一个波长的时间,支持开启和暂停动画
9 | - 支持设置移动方向(左、右)
10 | - 支持设置波浪位置(顶部、底部)
11 | - 支持两种绘制方式(贝塞尔曲线和三角函数曲线)
12 |
13 | ### 用法
14 | #### 1. 在 project 的 build.gradle 添加以下代码
15 | ```gradle
16 | allprojects {
17 | repositories {
18 | ...
19 | maven { url 'https://www.jitpack.io' }
20 | }
21 | }
22 | ```
23 | #### 2. 在 app 的 build.gradle 添加依赖
24 | ```gradle
25 | dependencies {
26 | implementation 'com.github.CaiShenglang:WaveView:1.0.3'
27 | }
28 | ```
29 | #### 3. 在 xml 添加 WaveView
30 | ```xml
31 |
51 | ```
52 | 自定义属性说明
53 |
54 | 自定义属性|类型|作用
55 | ---|:-:|---
56 | startAnim|boolean|是否开启动画,默认开启
57 | waveCount|integer|波浪数量,默认显示一个
58 | waterLevelHeight|dimension|水位高度,默认是控件高度 - 最大振幅
59 | waveColor|color|第一个波浪的颜色
60 | waveColor2|color|第二个波浪的颜色
61 | waveAmplitude|dimension|第一个波浪的振幅
62 | waveAmplitude2|dimension|第二个波浪的振幅
63 | waveLength|dimension|第一个波浪的波长,默认是控件宽度
64 | waveLength2|dimension|第二个波浪的波长,默认是控件宽度
65 | waveLengthPercent|float|第一个波浪占控件宽度的百分比
66 | waveLengthPercent2|float|第二个波浪占控件宽度的百分比
67 | waveDefOffset|dimension|第一个波浪的初始偏移量
68 | waveDefOffset2|dimension|第二个波浪的初始偏移量
69 | waveDefOffsetPercent|float|第一个波浪默认偏移量占波长的百分比
70 | waveDefOffsetPercent2|float|第二个波浪默认偏移量占第二个波长的百分比
71 | cycleDuration|integer|第一个波浪移动一个周期的时长
72 | cycleDuration2|integer|第二个波浪移动一个周期的时长
73 | moveDirection|left、right|移动方向,默认向右(向左、向右)
74 | waveLocation|top、bottom|波浪位置,默认在底部(顶部、底部)
75 | drawMode|bezier、sin、cos|绘制的模式,默认是贝塞尔曲线绘制(贝塞尔曲线、正弦曲线、余弦曲线)
76 | #### 4. 如果需要动态设置开始或停止动画
77 | ```java
78 | mWaveView = findViewById(R.id.wave_view);
79 | mWaveView.startAnim(); // 开始或继续动画
80 | mWaveView.stopAnim(); // 暂停动画
81 | ```
