Question

我正在尝试使用自定义格式（例如dd-MMM-yyyy（10-aug-1982））从日期选择器对话框中捕获日期。我使用了以下代码，但只接受整数值作为月而不是字符串。请参阅我想要从日期选择器发送到编辑文本的注释代码。

请任何人指导我如何将月份作为字符串返回。在此先感谢。以下是我的代码。

XML

    <EditText
        android:id="@+id/date"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:background="#d4d4d4"
        android:inputType="none"
        android:textIsSelectable="true"
        android:hint="Select Date..."
        android:padding="15dp"
        android:textColor="#897"
        android:textColorHint="#090"
        android:textSize="20sp"
        android:textStyle="bold" />
</RelativeLayout>

更改为以下

// date picker dialog
datePickerDialog = new DatePickerDialog(MainActivity.this,
        new DatePickerDialog.OnDateSetListener() {
          @Override
             public void onDateSet(DatePicker view, int year,
                                           int monthOfYear, int dayOfMonth){
                                Calendar calendar = Calendar.getInstance();
                                calendar.set(year, monthOfYear, dayOfMonth);
                                SimpleDateFormat format = new SimpleDateFormat("dd-MMM-yyyy");
                                String dateString = format.format(calendar.getTime());
                                date.setText(dateString);
                            }
                        }, mYear, mMonth, mDay);

Answer 2

使用“ EEEE dd”代替“ dd”来获取日期名称。就像2019年10月25日星期五。

            // date picker dialog
            datePickerDialog = new DatePickerDialog(MainActivity.this,
                    new DatePickerDialog.OnDateSetListener() {
                        @Override
                        public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth)
                        {
                            Calendar calendar = Calendar.getInstance();
                            c.set(year , monthOfYear , dayOfMonth);
                            SimpleDateFormat format = new SimpleDateFormat("EEEE dd-MMM-yyyy");
                            String datestring=format.format(calendar.getTime());
                            editText.setText(datestring);
                        }
                    }, mYear, mMonth, mDay);
