使用WheelCurvedPicker，在没有上下滑动过的时候调用setItemIndex没有问题，但是有过上下滑动之后再调用就会出现乱跳现象。

经过debug发现unitDeltaTotal变量没有制空导致的，所以我试了复写setItemIndex方法就好了。 @Override public void setItemIndex(int index) { super.setItemIndex(index); unitDeltaTotal = 0; }

WheelCurvedPicker具体逻辑看上去非常复杂，不是很了解，所以没有提Pull request。

I am trying to extend your wheel picker and change item spacing and text size.

This case work OK:

setItemSpace(18); setItemTextSize(54);

java.lang.ArithmeticException: divide by zero at com.aigestudio.wheelpicker.WheelPicker.onDraw(WheelPicker.java:505) :

setItemSpace(27); setItemTextSize(54);

when i setItemIndex to the WheelHourPicker, the picker show the view error, for example, when i set WheelHourPicker.setCurrentHour(6); the picker show 3 but when first entry the activity,set setCurrentHour is true. Once i scroll the wheel picker, the method setcurrenthour will error

建议在run()方法中先检查data的是否有数据再执行滑动. @Override public void run() { _if(mData==null || mData.size()<=0){ return; }_ if (mScroller.isFinished() && !isForceFinishScroll ) { .... }}

I've tested below scenario on your latest demo 1.1.0.

I've array of 20. What I need is if User select position 2 then I want spinner to rotate to 3rd position. So onItemSelected callback I've written as below.

public void onItemSelected(WheelPicker picker, Object data, int position) { String text = ""; switch (picker.getId()) { case R.id.main_wheel_left: if (position == 2) { wheelLeft.setCurrentItem(1); } text = "Left: " + position + " :: "; break; case R.id.main_wheel_center: text = "Center:"; break; case R.id.main_wheel_right: text = "Right:"; break; } Toast.makeText(this, text + String.valueOf(data), Toast.LENGTH_SHORT).show(); }

I'm stuck with Two Issues. It's not sending me to 1st position on call of setCurrentItem(1) and this condition not working for second time.

First I am setting data to wheel picker and then I called setSelectedItemPosition(pos) method, data is properly setting but it showing me on 0 index position.

Here is my code(Kotlin).

var datePos = 0
val startDateView = view.findViewById(R.id.start_date_view) as WheelPicker
startDateView.apply {
            datePos =
                Calendar.getInstance().get(Calendar.DAY_OF_MONTH) - 1 // Get current date position
            setOnItemSelectedListener { picker: WheelPicker?, data1: Any?, position: Int ->
                datePos = position
            }
            data = Constants.getDatesRange() // setting data to wheel picker
            setSelectedItemPosition(datePos)
        }

XML Code

                                aigestudio:wheel_selected_item_text_color="#000" />

例如我显示的是两个WheelPicker, 一个是小时，一个是分钟， 但因为是弄课程表，有些时间段不可用，故会出现每个小时对应的分钟不一定一样，而有些小时对应的那个分钟列表只有一个元素，然后在视图上，上下部分都显示出这个元素了。。请问怎么隐藏？（例：8：00，8点只有一个00分，没有其他，所以分钟的WheelPicker里的元素只有一个, 但是视图上显示出很多个“00”，但我只需要显示一个。。）

RT，重点代码如下： ` minPicker.setOnWheelChangeListener(new WheelPicker.OnWheelChangeListener() { @Override public void onWheelScrolled(int offset) {

        }

        @Override
        public void onWheelSelected(int position) {
            for (int i = 0; i < numberList.size(); i++) {
                if (numberList.get(i) == minNumberList.get(position)) {
                    maxNumberList.clear();
                    maxNumberList.addAll(numberList.subList(i, numberList.size()));
                    break;
                }
            }
            maxPicker.setData(maxNumberList);
        }

        @Override
        public void onWheelScrollStateChanged(int state) {

        }
    });

    maxPicker.setOnWheelChangeListener(new WheelPicker.OnWheelChangeListener() {
        @Override
        public void onWheelScrolled(int offset) {

        }

        @Override
        public void onWheelSelected(int position) {
            for (int i = 0; i < numberList.size(); i++) {
                if (numberList.get(i) == maxNumberList.get(position)) {
                    minNumberList.clear();
                    minNumberList.addAll(numberList.subList(0, i));
                    return;
                }
            }
            minPicker.setData(minNumberList);
        }

        @Override
        public void onWheelScrollStateChanged(int state) {

        }
    });`

this library is used in a react native package I'm trying to test, whenever i run the app after installing that package I'm getting the following error: Could not resolve cn.aigestudio.wheelpicker:WheelPicker:1.0.3. > Could not get resource 'https://www.jitpack.io/cn/aigestudio/wheelpicker/WheelPicker/1.0.3/WheelPicker-1.0.3.pom'. > Could not GET 'https://www.jitpack.io/cn/aigestudio/wheelpicker/WheelPicker/1.0.3/WheelPicker-1.0.3.pom'. Received status code 401 from server: Unauthorized

Is there any solution for this issue, or is this library dead and I have to look for something else?

Hello,

I am trying to use wheel Picker in my react native app. I am using a react-native-wheel-picker library that uses WheelPicker from AigeStudio for android.

But I am getting the following error.

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.

     Required by:
         project :app > project :gregfrench_react-native-wheel-picker

I also forced the library to use the latest 1.1.3 version by making changes in the library Gradle file.

But I get the same error again.

Is anyone facing the same issue?

Thanks in advance for your help.

Font resource can be set through app:wheel_font_family attribute.

Example: If you have a my_font family in your font resource directory, then you'll set:

<com.aigestudio.wheelpicker.WheelPicker
    ...
    app:wheel_font_family="@font/my_font"
    ... />

Note: font set from font resources will override fonts set from assets folder with app:wheel_font_path.
