android - NumberPicker 中的 java.lang.IndexOutOfBoundsException

Question

在 Android 的预发布报告中，我收到以下错误。在观看记录时，当机器人选择一个值时它会崩溃，但我无法复制该问题。如果您需要更多信息，请与我们联系。如何解决此错误？

号码选择器是这样设置的

    numberPicker.setMaxValue(stringArrayOfCurrentPickerViewArray.length - 1);
    numberPicker.setMinValue(0);
    numberPicker.setDisplayedValues(stringArrayOfCurrentPickerViewArray);
    numberPicker.setWrapSelectorWheel(false);
    numberPicker.setSaveFromParentEnabled(false);
    numberPicker.setSaveEnabled(true);

And when a value is selected

            int row = numberPicker.getValue();
            if (row != 0) {
                if (row > 0 && row <= stringArrayOfCurrentPickerViewArray.length - 1) {
                    textField.setText(stringArrayOfCurrentPickerViewArray[row]);
                }
            }
