Problem with datas

[helsephas]

Hello, first, i m sorry i don't speak chinese. I want to know if i can adapt the list at runtime for exemple:

• wheel A contains A1,A2,A3

• wheel B contains B1A1,B2A1, B1A2,B2A2, B1A3,B2A3, So if A1 if selected B1A1 and B2A1 is showing, A2 B1A2 and B2A2, etc , ...
  Thanks a lot

我试图用中文来传播 你好，首先，我很抱歉，我不会说中文。 我想知道我是否可以在运行时调整列表，例如： 轮A包含A1，A2，A3 轮B包含B1A1，B2A1， B1A2，B2A2， B1A3，B2A3， 所以如果A1如果选择B1A1和B2A1显示，A2 B1A2和B2A2等...

@helsephas You mean that you need the options change as long as item changes? or next time you open it, change the default selection? “So if A1 if selected B1A1 and B2A1 is showing, A2 B1A2 and B2A2, etc , ...” Can you describe it more clearly? I don't quite understand this. Waiting for your reply~

Yes the options2 changes as long as item changes in option 1. Its seems to be like this : https://github.com/Bigkoo/Android-PickerView/blob/master/preview/JsonData.gif. Options2 list depends on options1 seletected item

@helsephas The steps to add datas are as follows:

private ArrayList<String> options1Items = new ArrayList<>();
private ArrayList<ArrayList<String>> options2Items = new ArrayList<>();

        //options1 data
        options1Items.add(A1);
        options1Items.add(A2);

        //options2

        ArrayList<String> options2Items_01 = new ArrayList<>();
        options2Items_01.add(B21);
        options2Items_01.add(B22);
        ArrayList<String> options2Items_02 = new ArrayList<>();
        options2Items_02.add(B11);
        options2Items_02.add(B12);

        options2Items.add(options2Items_01);
        options2Items.add(options2Items_02);

        pvOptions.setPicker(options1Items, options2Items);

@helsephas It can be either data of type String or entity data. If you add entity data，your entity class need implements ”IPickerViewData“ interface, and then, In the "getPickerViewText" method, returns the String data what you needs to be displayed.

[xiaosong520]

@helsephas set linkage picker data after you add data list, like this:

pvOptions.setPicker(options1Items, options2Items);
//or
pvOptions.setPicker(options1Items, options2Items,options3Items);

Thanks for your replies. I have make some tries but i m still blocked with this code and i seem to use your picker exactly like you

I m working in kotlin

I used this like this : var pickerViewDates = MyOptionsPickerView(this) pickerViewDates.setTitle(this.resources.getString(R.string.shopping_cart_pick_date_title)) var now : Date = Date() var days : ArrayList = ArrayList() var hours : ArrayList<ArrayList> = ArrayList() var minutes : ArrayList<ArrayList> = ArrayList() //init arrays pickerViewDates.setPicker(days,hours,minutes,true) pickerViewDates.setCyclic(true,true,true) pickerViewDates.show()

-> I get an error because type is mismatching (required: ArrayList<String!>! found ArrayList<ArrayList>

@helsephas Do you need to use timePicker? as follows:

        Calendar selectedDate = Calendar.getInstance();
        Calendar startDate = Calendar.getInstance();
        startDate.set(2013, 0, 1);

        Calendar endDate = Calendar.getInstance();
        endDate.set(2017, 11, 1);

        pvTime = new TimePickerView.Builder(this, new TimePickerView.OnTimeSelectListener() {
            @Override
            public void onTimeSelect(Date date, View v) {//callback
            }
        })
                .setType(new boolean[]{false, false, false, true, true, true}) // day - hour - minute
                .setLabel("", "", "", "", "", "")
                .setDividerColor(Color.DKGRAY)
                .setContentSize(21)
                .setDate(selectedDate)
                .setRangDate(startDate, endDate)
                .build();
    }

@helsephas Calendar's month value is 0-based. e.g., 0 for January.

I can't use time picker because i got a set of ranges dates for example i will get 17 july 8->16 hours 0-> 59 minutes 19 july 8->16 hours 0-> 59 minutes 21 july 9-> 20hours 0-> 59 minutes etc etc thats why i use String and not date. My problem is that i can't add arrayList like you did in your example for option 2 because i said that my optionPickerView will be type String and not ArrayList of String thats what i don't understand and we got the same code apparently

[xiaosong520]

@helsephas 1. You can used the linkage datatype. For details, please refer to the fourth reply , dataType :

var days : ArrayList = ArrayList() 
var hours : ArrayList<ArrayList> = ArrayList()
var minutes : ArrayList<ArrayList<ArrayList>> = ArrayList()

2. Or self modify the source code to implement this function( let option1 and option2 linked, option3 is no-linkage), dataType :

   var days : ArrayList = ArrayList()
   var hours : ArrayList<ArrayList> = ArrayList()  // depend on day
   var minutes : ArrayList = ArrayList()     // 0-59

Oki i m sorry for all this. Because my problem was simply that : I used MyOptionsPickerView and not OptionsPickerView so i waste our both time. I m sorry for this. Thanks for all this replies and for your time. Have a nice day.
