您好,感谢您的关注,很荣幸您采用这个控件。
您使用的方法和我设计的不太一致,所以您的这种使用方式是不合适的,您的代码:
minutePicker.setDisplayedValues(new String[2]{"00", "30"}); minutePicker.setMinValue(0); minutePicker.setMaxValue(30);
实际上,我的这个setMinValue(0) setMaxValue(30) 的意思是,第0个item的值为setMinValue(0),第n个(最后一个) item的值为setMaxValue(n),也就是说,minValue 至 maxValue 的值是每个item加一的。这样设计的使用场景是:比如我要选择年,从1900年开始,到2099年结束,此时,我就这样设置:
minutePicker.setDisplayedValues(new String[200]{"1900",“1901”,...., "2099"});
minutePicker.setMinValue(0);//或者 0 + n
minutePicker.setMaxValue(2099 - 1900);//如果是0 + n,那么这里就是 2099 - 1900 + n
也就是说,需要保证,maxValue-minValue的值等于或者小于 displayedValue的长度,即 maxValue减去minValue 的值代表的是 要显示出来的 item的数量,这样设计的好处是,如果用户想显示1900到1999,那么minValue不需要动,只需要setMaxValue为100就可以了。
不知道这样说,您是否理解了。minValue 、 maxValue 只代表开始item到最后item的索引。一般设置minValue为0

明白了,就是你的minValue和maxValue其實是代表position。
這樣我覺得這個命名頗誤導的,看你要不要考慮換掉囉。

差不多就是代表position吧,min max 相减是显示的个数。
名字确实容易产生歧义,之前这么做主要是因为android原生的 NumberPicker 是这么设计的,他的api也是这样设计的,所以我就直接拿过来了,以便于适配。
