`void`	`setCurtain(boolean hasCurtain)` 设置滚轮选择器是否显示幕布设置滚轮选择器显示幕布的话将会在当前选中的项上方绘制一个与当前数据项大小一致的矩形区域并填充指定颜色 Set whether WheelPicker display curtain or not WheelPicker will draw a rectangle as big as current selected item and fill specify color above content if curtain display
`void`	`setCurtainColor(int color)` 设置滚轮选择器幕布颜色 Set color of curtain For example 0xFF123456
`void`	`setCurved(boolean isCurved)` 设置滚轮选择器是否开启卷曲效果开启滚轮选择器的滚轮效果会呈现一种滚轮两端向屏幕内弯曲的效果滚轮选择器的卷曲效果依赖于严格的几何模型，一些与尺寸相关的设置在该效果下可能会变得不再有效，例如在卷曲效果下每一条数据项的尺寸大小因为透视关系看起来都不再一样，数据项之间的间隔也会因为卷曲的关系有微妙的视觉差距 Set whether WheelPicker enable curved effect or not If setCurved true, WheelPicker will display with curved effect looks like ends bend into screen with perspective.
`void`	`setCyclic(boolean isCyclic)` 设置滚轮选择器数据项是否为循环状态开启数据循环会使滚轮选择器上下滚动不再有边界，会呈现数据首尾相接无限循环的效果 Set whether WheelPicker is cyclic or not WheelPicker's items will be end to end and in an infinite loop if setCyclic true, and there is no border whit scroll when WheelPicker in cyclic state
`void`	`setData(List data)` 设置数据列表数据源可以是任意类型，但是需要注意的是WheelPicker在绘制数据的时候会将数据转换成String类型在没有设置数据源的情况下滚轮选择器会设置一个默认的数据源作为展示为滚轮选择器设置数据源会重置滚轮选择器的各项状态，具体行为参考 `IWheelPicker.setSelectedItemPosition(int)` Set data source of WheelPicker The data source can be any type, WheelPicker will change the data to string when it draw the item.
`void`	`setDebug(boolean isDebug)` 设置调试模式开启调试模式有可能在一定程度上降低代码执行效率，请务必在正式发布时关闭调试模式
`void`	`setIndicator(boolean hasIndicator)` 设置滚轮选择器是否显示指示器如果设置滚轮选择器显示指示器，那么将会在滚轮选择器的当前选中数据项上下显示两根分割线需要注意的是指示器的尺寸并不参与滚轮选择器的尺寸计算，其会绘制在滚轮选择器的上方 Set whether WheelPicker display indicator or not WheelPicker will draw two lines above an below current selected item if display indicator Notice:Indicator's size will not participate in WheelPicker's size calculation, it will drawn above the content
`void`	`setIndicatorColor(int color)` 设置滚轮选择器指示器颜色 Set color of indicator For example 0xFF123456

`void`	`setItemSpace(int space)` 设置滚轮选择器数据项之间间距 Set space between items Unit in px
`void`	`setItemTextColor(int color)` 设置数据项文本颜色 Set text color of items For example 0xFF123456
`void`	`setItemTextSize(int size)` 设置数据项文本尺寸大小 Set text size of items Unit in px
`void`	`setMaximumWidthText(String text)` 设置最宽的文本 Set maximum width text
`void`	`setMaximumWidthTextPosition(int position)` 设置最宽的文本在数据源中的位置 Set the position of maximum width text in data source
`void`	`setOnItemSelectedListener(WheelPicker.OnItemSelectedListener listener)` 设置滚轮Item选中监听器
`void`	`setOnWheelChangeListener(WheelPicker.OnWheelChangeListener listener)` 设置滚轮滚动状态改变监听器
`void`	`setSameWidth(boolean hasSameWidth)` 设置数据项是否有相同的宽度滚轮选择器在确定尺寸大小时会通过遍历数据源来计算每一条数据文本的宽度以找到最宽的文本作为滚轮选择器的最终宽度，当数据源的数据非常多时，这个过程可能会消耗大量的时间导致效率降低，而且在大部分数据量多情况下，数据文本大都有相同的宽度，这种情况下调用该方法告诉滚轮选择器数据宽度相同则可以免去上述计算时间，提升效率有些时候，你所加载的数据源确实是每条数据文本的宽度都不同，但是你知道最宽的数据文本在数据源中的位置，这时你可以调用`IWheelPicker.setMaximumWidthTextPosition(int)`方法告诉滚轮选择器最宽的这条数据文本在数据源的什么位置，滚轮选择器则会根据该位置找到该条数据文本并将其宽度作为滚轮选择器的宽度。
`void`	`setSelectedItemPosition(int position)` 设置当前被选中的数据项所显示的数据在数据源中的位置调用该方法会导致滚动选择器的位置被重新初始化，什么意思呢？
`void`	`setSelectedItemTextColor(int color)` 设置当前选中的数据项文本颜色 Set text color of current selected item For example 0xFF123456
`void`	`setTypeface(android.graphics.Typeface tf)` 设置数据项文本字体对象数据项文本字体的设置可能会导致滚轮大小的改变 Set typeface of item text Set typeface of item text maybe cause WheelPicker size change
`void`	`setVisibleItemCount(int count)` 设置滚轮选择器可见数据项数量滚轮选择器的可见数据项数量必须为大于1的整数这里需要注意的是，滚轮选择器会始终显示奇数个数据项，即便你为其设置偶数个数据项，最终也会被转换为奇数默认情况下滚轮选择器可见数据项数量为7 Set the count of current visible items in WheelPicker The count of current visible items in WheelPicker must greater than 1 Notice:count of current visible items in WheelPicker will always is an odd number, even you can set an even number for it, it will be change to an odd number eventually By default, the count of current visible items in WheelPicker is 7

```
    从接口复制的说明: IWheelPicker
    
    获取当前被选中的数据项所显示的数据在数据源中的位置需要注意的是，当滚轮选择器滚动时并不会改变该方法的返回值，该方法会始终返回 IWheelPicker.setSelectedItemPosition(int)所设置的值，当且仅当调用 IWheelPicker.setSelectedItemPosition(int)设置新值后，该方法所返回的值才会改变如果你只是想获取滚轮静止时当前被选中的数据项所显示的数据在数据源中的位置，你可以通过 WheelPicker.OnItemSelectedListener回调监听或调用 IWheelPicker.getCurrentItemPosition()
    Get the position of current selected item in data source Notice:The value by return will not change when WheelPicker scroll, this method will always return the value which IWheelPicker.setSelectedItemPosition(int) set, the value this method return will be changed if and only if call the IWheelPicker.setSelectedItemPosition(int) set a new value If you only want to get the position of current selected item in data source, you can get it through WheelPicker.OnItemSelectedListener or call IWheelPicker.getCurrentItemPosition() directly
    
    指定者:
    
    getSelectedItemPosition 在接口中 IWheelPicker
    
    返回:
    
    当前被选中的数据项所显示的数据在数据源中的位置

```

```
    从接口复制的说明: IWheelPicker
    
    设置当前被选中的数据项所显示的数据在数据源中的位置调用该方法会导致滚动选择器的位置被重新初始化，什么意思呢？假如你滑动选择到第五个数据项的时候调用该方法重新将当前被选中的数据项所显示的数据在数据源中的位置设置为第三个，那么滚轮选择器会清除掉上一次滚动的相关数据参数，并将重置一系列的数据，重新将第三个数据作为滚轮选择器的起点，这个行为很可能会影响你之前所根据这些参数改变的一些属性，比如 WheelPicker.OnWheelChangeListener和 WheelPicker.OnItemSelectedListener监听器中方法参数的值，因此你总该在调用该方法后考虑到相关影响你总该为该方法传入一个大于等于0小于数据源IWheelPicker.getData()长度的值，否则会抛出异常默认情况下，当前被选中的数据项所显示的数据在数据源中的位置为0
    Set the position of current selected item in data source Call this method and set a new value may be reinitialize the location of WheelPicker. For example, you call this method after scroll the WheelPicker and set selected item position with a new value, WheelPicker will clear the related parameters last scroll set and reset series of data, and make the position 3 as a new starting point of WheelPicker, this behavior maybe influenced some attribute you set last time, such as parameters of method in WheelPicker.OnWheelChangeListener and WheelPicker.OnItemSelectedListener, so you must always consider the influence when you call this method set a new value You should always set a value which greater than or equal to 0 and less than data source's length By default, position of current selected item in data source is 0

    Set data source of WheelPicker The data source can be any type, WheelPicker will change the data to string when it draw the item. There is a default data source when you not set the data source for WheelPicker.

```
public void setSameWidth(boolean hasSameWidth)
```
    从接口复制的说明: IWheelPicker
    
    设置数据项是否有相同的宽度滚轮选择器在确定尺寸大小时会通过遍历数据源来计算每一条数据文本的宽度以找到最宽的文本作为滚轮选择器的最终宽度，当数据源的数据非常多时，这个过程可能会消耗大量的时间导致效率降低，而且在大部分数据量多情况下，数据文本大都有相同的宽度，这种情况下调用该方法告诉滚轮选择器数据宽度相同则可以免去上述计算时间，提升效率有些时候，你所加载的数据源确实是每条数据文本的宽度都不同，但是你知道最宽的数据文本在数据源中的位置，这时你可以调用IWheelPicker.setMaximumWidthTextPosition(int)方法告诉滚轮选择器最宽的这条数据文本在数据源的什么位置，滚轮选择器则会根据该位置找到该条数据文本并将其宽度作为滚轮选择器的宽度。如果你不知道位置，但是知道最宽的数据文本，那么你也可以直接通过调用IWheelPicker.setMaximumWidthText(String)告诉滚轮选择器最宽的文本是什么，滚轮选择器会根据这条文本计算宽度并将其作为滚轮选择器的宽度
    Set items of WheelPicker if has same width WheelPicker will traverse the data source to calculate each data text width to find out the maximum text width for the final view width, this process maybe spends a lot of time and reduce efficiency when data source has large amount data, in most large amount data case, data text always has same width, you can call this method tell to WheelPicker your data source has same width to save time and improve efficiency. Sometimes the data source you set is positively has different text width, but maybe you know the maximum width text's position in data source, then you can call IWheelPicker.setMaximumWidthTextPosition(int) tell to WheelPicker where is the maximum width text in data source, WheelPicker will calculate its width base on this text which found by position. If you don't know the position of maximum width text in data source, but you have maximum width text, you can call IWheelPicker.setMaximumWidthText(String) tell to WheelPicker what maximum width text is directly, WheelPicker will calculate its width base on this text.
