TimePickerDialog和DatePickerDialog使用

TimePickerDialog

TimePickerDialog(Context context, 
        TimePickerDialog.OnTimeSetListener listener, 
        int hourOfDay, 
        int minute, 
        boolean is24HourView)

参数

context：当前上下文
listener：时间改变监听器
hourOfDay：初始化的小时
minute：初始化的分钟
is24HourView：是否以24小时显示时间

关键代码：

new TimePickerDialog(this,new TimePickerDialog.OnTimeSetListener() {

            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                textView.setText(hourOfDay+":"+minute);
            }
        }, 0, 0, true).show();

DatePickerDialog

用法和TimePickerDialog相同
首先调用Calendar类获取年月日，然后将获取到的年月日放进new出来的DatePickerDialog中，这样就可以默认选中当前日期

private void chooseDate(){
        Calendar ca = Calendar.getInstance();

        mYear = ca.get(Calendar.YEAR);
        mMonth = ca.get(Calendar.MONTH);
        mDay = ca.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog datePickerDialog = new DatePickerDialog(this,
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                        final String data =  year+"年"+(month+1) + "月" + dayOfMonth + "日 ";
                        textView.setText(data);
                    }
                },
                mYear, mMonth, mDay);
        datePickerDialog.show();
    }
