能水平方向吗，就行嘀嗒拼车的感谢费那种，我在做成AlertDialog.Builder的setView里设置您的NumberPickerView，非常希望能横着滑动。

能不能设置选中的背景颜色

假如我设置了一个时间 退出下次再进来选中的是我设置的那个时间可以实现吗？

I'm trying to disable NumberPickerView when a certain condition is met. For this, I used NumberPickerView#setEnabled(false);, but I got no change in behaviour: the view is still scrollable. Is there a way to really disable the NumberPickerView?

Thanks again for such a great library. You got any idea how I can fade/alpha top and bottom of view. So just like native number picker but I want to be able to increase/decrease that fade.

Trying / playing with mPaintText right now. Not sure if this would do or I may need to create another paint object. Let me know if you got any idea. :)

OnValueChangeListener中的onValueChange方法每次都要在选中后间隔1秒左右才能响应，OnValueChangeListenerInScrolling的onValueChangeInScrolling方法及时响应了，但是只记录选中值的上一个值，因此两个监听都无法很好的及时确定选中的值，请问有什么方法可以解决吗？

Enhancement:

I am trying to find a way to set default value.

use case :-
Current time is 3:06. When user go to specific screen, dev can take system time and feed that into numberpicker, so number picker would be set like 3:06 instead of showing the first element of the array.

这个控件https://github.com/saiwu-bigkoo/Android-PickerView 有3D效果！！给项目加的时候，他这个不够灵活!

RT

It would be nice to be able to set the number of rows shown programmatically.

我在项目中加了三个该View用作省市区三级联动 每个宽度都是屏幕的1/3 但是当遇到某些市名过长的时候 文字左右会显示不下 直接被切掉了

在xml文件中设置最小值和最大值的时候，如果没有设置npv_TextArray，会闪退，空指针异常。看了代码，发现最小值在里面只是用于数组下标的作用。而不是展示的作用。不知道是作者故意如此，还是一个bug

当待显示的数到一定范围时，就会被循环显示。比如，待显示的数为1，2，3，4，5，6，7，8，9，10，11，12，显示效果是在12下面会出现1，现在我希望12下面宁愿是空白，我要选1时，我宁愿往下滑。

I have developed a picker for some details but it scrolled to infinite.
How i can stop it at end of array list length ?

只想显示数字时用setMinValue()和setMaxValue()而不用setDisplayedValues()时会报错
Java代码：
NumberPickerView numberPicker = (NumberPickerView) findViewById(R.id.picker);
numberPicker.setMaxValue(10);
numberPicker.setMinValue(0);
numberPicker.setValue(2);
报错信息：
(maxValue - mMinValue + 1) should not be greater than mDisplayedValues.length now (maxValue - mMinValue + 1) is 11 and mDisplayedValues.length is 1
而原生的NumberPicker做同样的设置不会报错

I need create picker
-7 to 7

How configure picker?

Per default, the text is centered in the time picker. Is there a way to change the alignment to the left or right side? Thanks!

默认情况下，文本在时间选择器中居中。有没有办法改变左侧或右侧的对齐方式？谢谢！

If I set a listener to OnValueChangeListener and then try to modify any view in the callback method, I get the well know android exception:

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

I can't drag to scroll, and I don't see anything about dragging or flinging in the readme file even though it promises better flinging by adjusting friction...

怎么根据当前的日期，设置默认值

Only the original thread that created a view hierarchy can touch its views.

in demo ActivityTimePicker
line 65:
replace
setData(mPickerViewH, 0, 11, h);
with
setData(mPickerViewH, 3, 4, 4);

hour picker show 1 and 12
NOT 3 and 4

I think it's a bug.
if setMinValue is not 0, number picker view will not work.

我用这个库做省市区三级联动时遇到的问题，有的省份或者城市下没有区，通过refreshByNewDisplayedValues方法设置一个空的String数组，然后就会抛异常，能否处理这样的问题呢？
java.lang.IllegalArgumentException: mMaxValue - mMinValue + 1 should not be greater than mDisplayedValues.length, now ((mMaxValue - mMinValue + 1) is 1 newDisplayedValues.length is 0, you need to set MaxValue and MinValue before setDisplayedValues(String[])

想让内容点击一个按钮后自动循环滚动 类似于摇奖机效果 然后点击一个按钮暂停滚动.

final String[] mDisplayValues=new String[]{"今天","明天","后天"};
numberPicker.setDisplayedValues(mDisplayValues);
numberPicker.setMinValue(0);
numberPicer.setMaxValue(2);
显示正常。

但是，
numberPicker.setMinValue(1);//代码中需要动态调节minValue进行限位
发生了两个问题：
1、由于限位造成的value改变，并没有触发onValueChanged事件
2、在numberPicker中，预期效果应该显示为 明天、后天，实际显示为 今天、明天
并且，UI显示的"今天"所对应的value为“明天”(1)，也就是说，UI显示的值与实际的value出现了不一致的情况,实际的值是正确的,而UI显示的是错误的。
一个好用的控件，其显示范围应该能由setMinValue()和setMaxValue()来决定。

粗略的看下源代码，貌似不能简单的实现颜文字支持？
不知道是否可以提供些思路？
多谢！

THANK YOU SO MUCH for sharing and your hard work. Would like to add a bit more enhancement :)

Maybe, it's better to keep this method public so we can call when user press a button

Use case -
User (fling) scrolling > Quickly press OK/Pick button > number picker should stop at that value and stop scrolling animation

Making this method public already does stop the scroll animation and stop at picked value. 👍

public void stopScrolling() {
        if (mScroller != null) {
           ...
        }
    }

Hi! Is there somehow a way to set drawable as background of divider?
I see you use private method drawLine(Canvas canvas) to draw simple divider-lines. So is it ok to just call any other 'draw' method on canvas instead?

Can we give font to numberpicker?

你好，沒想到你這個庫我已經用了兩個項目，這個需求在第三個項目才出現。

比如說我想用你的庫做一個時間的選擇器，分鐘只可以選 0 和 30，

那我基本上是這樣做：

        minutePicker.setDisplayedValues(new String[2]{"00", "30"});
        minutePicker.setMinValue(0);
        minutePicker.setMaxValue(30);

可是這樣會拋異常，因為你會檢查 (maxValue - mMinValue + 1 > mDisplayedValues.length)，如果為true會拋異常。這樣看來你好似只支援連續的數字，是這樣嗎？

(當然了我可以自己弄一個List，只監聽picker返回的position。是這樣嗎？)

当调用setEnabled(false)把控件设置为不可用状态后，内部没有做相关的处理。

1. onTouchEvent 事件应该在不可用时不处理
2. setSelectedTextColor，setNormalTextColor， 应该可以设置selector
3. 字体大小，代码中无法设置，只可以在xml设置，有点不方便。

在README.MD中：

2)若设置的数据(String[] mDisplayedValues)会改变，可以使用如下组合方式进行设置：（与NumberPicker的更改数据方式一致）

        int minValue = getMinValue();
        int oldMaxValue = getMaxValue();
        int oldSpan = oldMaxValue - minValue + 1;
        int newMaxValue = display.length - 1;
        int newSpan = newMaxValue - minValue + 1;
        if (newSpan > oldSpan) {
            setDisplayedValues(display);
            setMaxValue(newMaxValue);
        } else {
            setMaxValue(newMaxValue);
            setDisplayedValues(display);
        }

或者直接使用NumberPickerView提供的方法：

refreshByNewDisplayedValues(String[] display)

使用此方法时需要注意保证数据改变前后的minValue值不变，以及设置的display不能够为null，且长度不能够为0。

如果使用与NumberPicker的更改数据方式一致的方法，可以更改最小值么？

你好大佬 请问该框架的混淆模板怎么写

比如我要选择1970年到2020年，就需要在string.xml中配置一堆数字。能不能对数值范围做一个支持，试了下setMinValue和setMaxValue貌似他会检查范围是否小于displayValue的长度，不配置textArray的话会报异常

当改变 displayedValues 的时候，监听器会失效，等一会才会有反应，希望能够改进

app:npv_ShowCount="当前加载的数组的长度“ 时，smoothScrollToValue()这个函数就不起作用了

例如我提供一个最小值 每次增加1最大值为30的纯数字NumberPickerView，我不想设置给NumberPickerView一个String类型的数组，该怎么弄？

我超喜歡這個控制，你簡直救了我一命啊！
Android自5.0之後的Date Picker逼你顯示日曆，如果我只是想用戶選月份和年份，日曆根本無法接受；
原生的NumberPicker又完全不能客制…

不過我發現一個問題，onValueChangeInScrolling回傳的newVal不正確，
而具體如何不正確則很難描述。
我有兩個NumberPickerView，一個是月份，一個是年份；
月份有12個數值，1到12
年份從1935到2100

我用debugger查看newVal的回傳數值；月份總是比最終停留的數值少2；
年份則是回傳了position，比如說我是1935開始，掃過1936，newVal回傳1。

如果這個可以解決就完美了～～ 我現在只能靠原本的onValueSelectedListener，沒有完全停定的話它就不懂得更新數值了

謝謝！

I to change the default typeface/font for NumberPickerView?
I want use a custom font.

npv_ShowCount 跟数据的长度相同时 npv_WrapSelectorWheel 失效

可以设置不循环滚动么？

我控件中只想显示一条数据用来滑动，
如何去除选中项顶部和底部默认黄色的横条？

private void setPicker(NumberPickerView picker, int start, int end) {
String[] texts = new String[end - start + 1];
for (int i = start; i <= end; ++i) {
texts[i - start] = String.valueOf(i);
}

int size = Math.abs(Math.min(start, picker.getMinValue()) - Math.max(end, picker.getMaxValue())) + 1;
picker.setDisplayedValues(new String[size]);
picker.setMinValue(start);
picker.setMaxValue(end);
picker.setValue(start);
picker.setDisplayedValues(texts);

}
这样的话没问题，setMaxValue如果和setMinValue对调时，滚动就会划出边界，还有闪退，建议给点提示。

Hey it's me again! 😄

I'm using the NumberPicker inside a RecyclerView, inside a NestedScrollView. I have the version 1.0.3. I noticed that when I call nofifyItemChanged(int) on the item that contains the NumberPicker, the NumberPicker sometimes goes "numb", as in it doesn't attach to the closest value when I scroll anymore. When this happens, it gives me the following exception:

Here is how I initialize the NumberPicker:

final String[] servings = new String[]{"01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"}; //holder.servings is the NumberPicker. holder.servings.setMinValue(1); holder.servings.setDisplayedValues(servings); holder.servings.setMaxValue(20); if (currentRecipe.serves > 0) holder.servings.setValue(currentRecipe.serves); else holder.servings.setValue(1); holder.servings.setOnValueChangedListener(new NumberPickerView.OnValueChangeListener() { @Override public void onValueChange(NumberPickerView picker, int oldVal, int newVal) { RecipeIngredientsAdapter.this.servings = newVal; RecipeIngredientsAdapter.this.notifyItemRangeChanged(0, getItemCount()-1); } });

Here's the layout:
<cn.carbswang.android.numberpickerview.library.NumberPickerView android:id="@+id/recipe_ingredients_servings" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@android:color/transparent" app:npv_ItemPaddingHorizental="5dp" app:npv_TextColorNormal="@android:color/white" app:npv_TextColorSelected="@android:color/white" android:layout_gravity="center_horizontal|top" app:npv_ShowCount="1" app:npv_MinValue="1" app:npv_MaxValue="20" app:npv_ShowDivider="false" app:npv_TextSizeNormal="40sp" app:npv_TextSizeSelected="40sp" app:npv_WrapSelectorWheel="false"/>

(By the way, I noticed you mistyped npv_ItemPaddingHorizental)

app:npv_WrapSelectorWheel="true" property not wokring... Tried both in XML as well as in Java

Can we edit numberpicker middle value from keyboard value?

现在列表中显示的10:30，中间的“:”这个符号太靠近下面了。我在软件中用了全局的字体。但是这儿没有自动替换。怎么样能给中间的“:”这个符号让处于中间呢？
注：
如果输入中文符的“：”，显示的时候效果会变成：“10： 30”
中间距离太大，求方案！谢谢各位大神！
