Hi,

Extremely sorry for the delayed response. PFA Crash log with source code used.

Source Code which I have used is :

private void MakeBudgetRangeReady() { try { ArrayList options1Items = new ArrayList<>(); ArrayList<ArrayList> options2Items = new ArrayList<>(); ArrayList<ArrayList<ArrayList>> options3Items = new ArrayList<>();

    for (int i = 0; i < 100; i++) {
        options1Items.add("i " + i);
    }
    for (int i = 0; i < 100; i++) {
        ArrayList<String> options2Items_01 = new ArrayList<>();
        for (int j = 0; j < 100; j++) {
            options2Items_01.add("j " + j);
        }
        options2Items.add(options2Items_01);
    }
    for (int i = 0; i < 100; i++) {
        ArrayList<ArrayList<String>> options2Items_01 = new ArrayList<>();
        for (int j = 0; j < 100; j++) {
            ArrayList<String> options2Items_02 = new ArrayList<>();
            for (int k = 0; k < 100;k++) {
                options2Items_02.add("k " + k);
            }
            options2Items_01.add(options2Items_02);
        }
        options3Items.add(options2Items_01);
    }

    OptionsPickerView budgetOptions = new

OptionsPickerView.Builder(context, new OptionsPickerView.OnOptionsSelectListener() { @Override public void onOptionsSelect(int options1, int options2, int options3, View v) { Log.i(TAG, "onOptionsSelect: " + options1 + "\t" + options2 + "\t" + options3); } }) .setTitleText("城市选择") .setContentTextSize(20)//设置滚轮文字大小 .setDividerColor(Color.LTGRAY)//设置分割线的颜色 .setSelectOptions(0, 1)//默认选中项 .setBgColor(Color.BLACK) .setTitleBgColor(Color.DKGRAY) .setTitleColor(Color.LTGRAY) .setCancelColor(Color.YELLOW) .setSubmitColor(Color.YELLOW) .setTextColorCenter(Color.LTGRAY) .isCenterLabel(false) //是否只显示中间选中项的label文字，false则每项item全部都带有label。 //.setLabels("省", "市", "区") .setBackgroundId(0x66000000) //设置外部遮罩颜色 .build();

    //pvOptions.setSelectOptions(1,1);
    budgetOptions.setPicker(options1Items, options2Items,

options3Items);//三级选择器 budgetOptions.show(); } catch (Exception e) { e.printStackTrace(); }

}

Note : It works fine on some better performance devices but on fewer devices which i have used for testing like Samsung Mega 5.8(Jelly Bean) or YU5010(Lollipop 5.0.1) it crashes with the given Log.

@punks1323 Time consuming processing cannot be done in the main thread，so you need do like this( pseudo code ):

runOnBackgroundThread(){
// step one :  init data source.
// step two :  init  picker view.
// call runOnUiThread()；
}

runOnUiThread(){
//  step three :  show  picker view.
}
