EditText 上的自定义 DatePicker

Question

我有 2 个 EditText.

当有人点击 EditText 日期选择器时，系统会显示日期选择器以在 EditText 中设置日期。所以我对 EditText 的编码是

    sdate.setOnTouchListener( new DrawableClickListener.RightDrawableClickListener(sdate)
                {
                    @Override
                    public boolean onDrawableClick()
                    {
                         MyDatePickerDialog(sdate);// put edit text view. 
                          return true;                     
                    }                   
                } );
                edate.setOnTouchListener( new DrawableClickListener.RightDrawableClickListener(edate)
                {
                    @Override
                    public boolean onDrawableClick()
                    {
                         MyDatePickerDialog(edate);// put edit text view. 
                         return true;                   
                    }
                } );

我的自定义日期选择器是

    private void MyDatePickerDialog(final EditText sdate) {
        Toast.makeText(getApplicationContext(),"sdgfdg" , Toast.LENGTH_LONG).show();
        DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                    int dayOfMonth) {
                // TODO Auto-generated method stub
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                updateLabel();
            }

            private void updateLabel() {
                 String myFormat = "MM/dd/yy"; //In which you need put here
                    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

                    sdate.setText(sdf.format(myCalendar.getTime()));
            }

        };

    }

但问题是显示了 toast 消息，但它不显示 datepicker

Answer 1

您只创建了 DatePickerDialog 的监听器，而没有创建 DatePickerDialog 本身。

你必须这样做：

DatePickerDialog datePickerDialog = new DatePickerDialog(
                getApplicationContext(), your Listener, year, month, dayOfMonth);
        datePickerDialog.show();

Answer 2

您只有一个自定义方法，您需要为 OnDateSetListener 创建一个侦听器以传递您的 DatePickerDialog

 private void MyDatePickerDialog(final EditText sdate) {
    Toast.makeText(getApplicationContext(),"sdgfdg" , Toast.LENGTH_LONG).show();
     Calendar newCalendar = Calendar.getInstance();
     DatePickerDialog myPickerDialog = new DatePickerDialog(this, new OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

            updateLabel();
        }

    },newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));

        private void updateLabel() {
             String myFormat = "MM/dd/yy"; //In which you need put here
                SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
                sdate.setText(sdf.format(newCalendar.getTime()));
        }

    myPickerDialog.show();

  }

注意： 您可以使用 onClickListener 而不是 onTouchListener。
