相关疑难解决方法(0)

我有自定义日期选择器和时间选择器.它正好工作在21级api,但在它不工作之后.我调试了代码并且知道在更改日期时没有调用ondatechanged和ontimechanged.

那么如何解决这个问题呢.

DatePicker的自定义类是 -

public class DatePickerDialog extends Dialog implements OnDateChangedListener,OnClickListener{

    private static DatePickerDialog dialog;
    private String date;
    private String title;
    private DatePickerCallback callback;
    private DatePicker datePicker;
    private TextView tvHeading;
    private Button btnDone;
    private String lastModifiedDate;
    private String initialDate;
    private boolean isStartDateToday;
    private long currentDateInMS = 0;
    private Context context;
    private int noOfDaysBefore = 0;

    public DatePickerDialog(Context context, DatePickerCallback callback, String date, String title, boolean isStartDateToday,int noOfDaysBefore) {
        super(context);
        this.context = context; …

我DatePickerDialog使用此处显示的示例实现了一个.

在我的实现中,DatePickerDialog.OnDateSetListener我添加了验证逻辑,以检查所选日期是否在特定范围内.

private final DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int y, int m,
            int d) {

            final Calendar calendar = Calendar.getInstance();
            calendar.set(y, m, d);
            Date date = calendar.getTime();

      if(!myValidationFunction(date)) {
        // date not within allowed range
        // cancel closing of dialog ?
      }
    }
};

我DatePickerDialog遇到的问题是,当用户单击设置按钮时,它会自动关闭,DatePickerDialog如果验证规则失败,我想保持打开状态.

DatePickerDialog当用户点击"设置"按钮时,是否有人知道如何停止关闭？
