94 | 95 | 计算当前条目位置preCurrentIndex（处理超出边界的情况） 96 | 计算滚动超出条目的位移： 97 | int j2 = (int) ((float) totalScrollY % itemHeight); 98 | 99 | 绘制各个条目： 100 | 101 | 计算条目弧度radian 102 | 103 | 计算图纸canvas偏移量 104 | 105 | 图中的弧度标错了，应该标它的补角，那样感觉不好理解，大家自行脑补一下 106 | 107 | h2也标错了，画图的时候忘记考虑空白区域了，h2应该是文字高度的sin值 108 | 109 | double h1 = Math.cos(radian) * (double) radius; 110 | 111 | double h2 = (Math.sin(radian) * (double) maxTextHeight) / 2D) 112 | 113 | int translateY = (int) ((double) radius h1 h2; 114 | 115 | 图纸延Y方向缩放，值为弧度radian的sin值（这样出来的效果就感觉是个圆柱） 116 | 117 | ### 最后分不同情况绘制各个条目 ### 118 | 1. 偏移量translateY y值小于第一条线firstLineY y值的并且偏移量translateY+maxTextHeight大于第一条线y值小于第一条线firstLineY y值的（即第一条线穿过该条目文字） 119 | 2. 条目文字穿过第二条线的情况 120 | 3. 条目刚好在两条线中间的 121 | 4. 其他情况 122 | 123 | onTouchEvent方法，当手离开控件时开始平滑滚动控件 124 | 125 | LoopViewGestureListener处理手势，当按下时取消所有的滚动，当滑行时，平滑滚动 126 | 127 | 平滑滚动用定时器ScheduledExecutorService来处理 128 | 129 | 哪里写的不对的多多指正。 130 | -------------------------------------------------------------------------------- /WheelViewDemo.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | -------------------------------------------------------------------------------- /androidWheelView-eclipse.rar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/weidongjian/androidWheelView/47f07204434598fbb1a877a6ca3409b11f7cb3e4/androidWheelView-eclipse.rar -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 29 5 | buildToolsVersion "29.0.3" 6 | 7 | defaultConfig { 8 | applicationId "com.weidongjian.meitu.wheelviewdemo" 9 | minSdkVersion 21 10 | targetSdkVersion 29 11 | versionCode 1 12 | versionName "1.0" 13 | // jackOptions { 14 | // enabled true 15 | // } 16 | } 17 | buildTypes { 18 | release { 19 | minifyEnabled false 20 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 21 | } 22 | debug { 23 | minifyEnabled false 24 | } 25 | } 26 | } 27 | 28 | 29 | dependencies { 30 | api fileTree(include: ['*.jar'], dir: 'libs') 31 | // api project(':loopview') 32 | api 'com.android.support:appcompat-v7:28.0.0' 33 | api 'com.github.weidongjian:androidWheelView:1.0.0' 34 | } 35 | 36 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in D:\Program Files (x86)\Android\android-sdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
