8 | 9 | ## 소개 10 | * Android Roulette Wheel View 11 | * library development post - 개발과정 (Korean) 12 | * https://jhdroid.tistory.com/23 13 | 14 |

15 | 16 | ## Gradle 17 | 18 | ### Project Gradle 19 | ```groovy 20 | allprojects { 21 | repositories { 22 | ... 23 | maven { url 'https://jitpack.io' } 24 | } 25 | } 26 | ``` 27 | 28 |

29 | 30 | ### App Gradle 31 | [![](https://jitpack.io/v/JhDroid/android-roulette-wheel-view.svg)](https://jitpack.io/#JhDroid/android-roulette-wheel-view) 32 | ```groovy 33 | dependencies { 34 | implementation 'com.github.JhDroid:android-roulette-wheel-view:{version}' 35 | } 36 | ``` 37 | 38 |

39 | 40 | ## How to use ? 41 | ### layout (xml) 42 | ```xml 43 | 48 | 49 | ``` 50 | * setup `android:layout_height` is `match_parent` (or ConstraintLayout : `0dp`) 51 | * (필수) `height`속성은 `match_parent`(ConstraintLayout은 `0dp`)설정해야 합니다. 52 | 53 |

54 | 55 | ### Use in Activity or Fragment 56 | ```kotlin 57 | val rouletteData = listOf("JhDroid", "Android", "Blog", "IT", "Developer", "Kotlin", "Java", "Happy") 58 | roulette.apply { 59 | setRouletteSize(8) // 2 ~ 8 60 | setRouletteDataList(rouletteData) 61 | } 62 | ``` 63 | 64 |

65 | 66 | ### rotate and get result 67 | ```kotlin 68 | fun rotateRoulette() { 69 | val rouletteListener = object : RotateListener { 70 | override fun onRotateStart() { 71 | // rotate animation start 72 | } 73 | override fun onRotateEnd(result: String) { 74 | // rotate animation end, get result here 75 | } 76 | } 77 | // random degrees (options) 78 | val toDegrees = (2000..10000).random().toFloat() 79 | roulette.rotateRoulette(toDegrees, 4000, rouletteListener) 80 | } 81 | ``` 82 | ```kotlin 83 | /** 84 | * Rotate roulette function 85 | * @param toDegrees : end angle (start angle is '0') 86 | * @param duration : rotate duration 87 | * @param rotateListener : rotate anim start, end listener (선택) 88 | * */ 89 | fun rotateRoulette(toDegrees: Float, duration: Long, rotateListener: RotateListener?) 90 | ``` 91 | 92 | 93 |
