好像获取不到Item的数值只能获取下标
设置滚轮enabled属性
怎样设置滚轮禁止滚动这个属性
在给你提个问题
loopview.setCurrentPosition(); 调用这个方法的时候。能加入移动动画最好
这样移动会平滑一点
setCurrentPosition(0) 还是有问题，会跳到数据的一半的位置
setCurrentPosition(0) 还是有问题，会跳到数据的一半的位置
第二次设置setInitPosition（0）不管用
有左右两个滚轮，右边数据是要随着左边数据发生变化，右边滚轮滚动一次之后，滚动左边滚轮，此时右边数据需要改变，把右边滚轮的初始位置设置为0；设置setInitPosition（0）不管用，请问该如何解决？
一个小问题
只有两个item 男和女 当我点击这两个item区域外面的时候，会出现一个小问题。能力有限修改不了，大神能去看看吗？ 谢谢啦
设置默认，不走监听
我设置了默认选中项，可是不走监听，能更新一下吗，这个样式很喜欢
删除java8的依赖后，没有发布啊

设计建议，能不能不要按半圆柱面显示。
用height做作为直径，显示的是半个圆柱的面，现在很多扁平话UI都不需要这么大弧度，我直接修改了半径变量，显示效果错误。你应该是用itemheight * count/pi来计算半径，强制用measuredHeight 作为直径和为text total hight，太不灵活了。可以考虑下建议，添加个0-180的参数来设置弧度，所有item肯定都是要显示在屏幕上的，设置半径就可以很容易控制弧度，基本适合所有wheel的ui设计了，这才是灵活的设计。快实现吧，现在只能先换个控件了，
radius = measuredHeight * 30;//直接让半径*30，效果错误
halfCircumference = (int) (radius * Math.PI);
// maxTextHeight = (int) (halfCircumference / (lineSpacingMultiplier * (itemsVisibleCount - 1)));
setCurrentPosition 方法里 position应该是大于等于0
public void setCurrentPosition(int position) {
//if (position >= 0 && position < items.size() && position != selectedItem) {
if (position > 0 && position < items.size() && position != selectedItem) {
initPosition = position;
totalScrollY = 0;
mOffset = 0;
invalidate();
}
}
How to setInitPosition as float value?
I need to set initial position as float value instead of integer, is there any way for it?
滑轮底部有下一个item的部分文字
大神，我在实际项目中使用该滑轮，在最底部有下一个item的部分文字，调整lineSpacingMultiplier大小无效，跪请大神帮忙。多谢了。我的邮箱：[email protected] 非常感谢！
设置俩个平行的数据的时候，两边同时滑动出现问题

上下两行设置渐变色
大神, 想问一下, 就是上下两行的字体绘制时颜色如何才能分开设置呀.
现在代码中上下两行字体的颜色是通过一个paint设置的.
我现在想设置一个渐变色.就是: 第一行是从黑到灰渐变. 第三行是从灰到黑渐变.
不知道要如何改.
望大神解答!
谢谢.
如果设置的数据条数小于可见数则crash

can't compile with java8 in android studio 2.2.2
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
中间选中的那行的整行背景色可以设置吗
大神你好。
中间选中的那行的整行背景色可以设置吗？默认时透明的。
Regarding Changing Font
@weidongjian Could you add a way to change font of the scroll items?
Thanks
setInitPosition()
if (items!=null&&(items.size()-1)>initPosition)
{
}
忘了加＝号，不然最后一个此方法选择不了
具体的属性都找不到了。。。。很难受
大神，把具体属性写出来，不然不会用啊
怎样更改行距？
我把DEFAULT_LINE_SPACE改成1.0F之后感觉每行的text还是隔得很宽。感觉是由translateY来决定的。
请问用的什么工具反编译的？

最新版得sample。setCurrentPosition(0)还是无效啊
setCurrentPosition(1)就可以。。。setCurrentPosition(0)不可以。。急求解决，老板
添加数据最好改为adpter的形式
只能接收字符串使用起来的耦合性太大了，建议仿照adpter view的形式加载数据。
初始化设定setInitPosition(N),但未滑动则getSelectedItem()=0
初始化loopView.setInitPosition(N)设置位置为任意数值N
在用户未滑动情况下,直接获取设定位置getSelectedItem()一直是0
滑动loopview后,getSelectedItem()才正常
建议把中间选中的item加个背景色属性设置
如题
当数据只有一条的时候，怎么控制它不让它滑动呢？
无法设置控件的宽度
固定宽度或者fill都不可以
设置可见数量严重问题
设置了没多大作用，设置过小，item太大
线穿过文字时候，文字有错位
中间的文字未垂直居中
如图，LoopView 布局高度设置的为150dp
此外，itemsVisibleCount也有问题，我这边是设置的7，显示5个
如果字数超过了一行，需要显示完全，该怎么处理。现在是显示不全的。
嵌套在ScrollView中有冲突
数据问题
我不想数据重复显示，滚动到第一条数据或最后一条数据时就不能滚动
i want to set font on scroll item's
hello
in my project i want to set font on scroll items
how to it possible ??
and same as your code are applied
LoopView.java 122行是为了当字体过线时有折射效果的
点击空白处 item index 会变乱
onSelectedItemClick
Hey,
Is there anyway to create an even when the user click on the selected item?
Thanks
设置控件大小后 文字 线 都有问题
有点击item的监听吗？
有点击item的监听吗？
莫名其妙的获取到下标为-1
没找到任何规律。。不知原因
宽度怎么控制？
设置控件的高度会影响item的高度，但是，线外的item就显示不全了。而且！！！高度很不好控制啊，还会影响字体的显示
