android:TimePickerDialog阻止用户选择过去的时间，并可以选择带有新日期的未来时间 [英] android: TimePickerDialog prevent user select past time and can select future time with new date

问题描述

我正在使用此链接 Android TimePickerDialog设置最大时间.

我是android的新手.在此代码的帮助下，我无法选择过去的时间，但我们无法选择未来的时间.在时间选择对话框模式中选择12时，将根据第二天而不是第二天自动更改为上午.

解决方案

尝试以下代码:

TimePickerFragment timePickerFragment = new TimePickerFragment();
            timePickerFragment.setOnTimeSetListener(new OnTimeSetListener() {
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    Calendar datetime = Calendar.getInstance();
                    Calendar c = Calendar.getInstance();
                    datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    datetime.set(Calendar.MINUTE, minute);
                    if (datetime.getTimeInMillis() >= c.getTimeInMillis()) {
                        //it's after current
                         int hour = hourOfDay % 12;
                    btnPickStartTime.setText(String.format("%02d:%02d %s", hour == 0 ? 12 : hour,
                            minute, hourOfDay < 12 ? "am" : "pm"));
                    } else {
                        //it's before current'
                        Toast.makeText(getApplicationContext(), "Invalid Time", Toast.LENGTH_LONG).show();
                    }
                }
            });
            timePickerFragment.show(getSupportFragmentManager(), "TIME");

它将显示timepicker对话框，并且如果用户选择当前时间之前的任何时间...则将显示无效时间.

编辑 您需要导入:

import android.app.TimePickerDialog;
import android.app.Fragment;
import android.app.DialogFragment;
import java.util.Calendar;
import android.widget.TimePicker;

这是一个很好的示例

I am using this link Android TimePickerDialog set max time.

I am new in android. With the help of this code, I cannot select past time but we cannot select future time. When 12 is selected in timepickerdialog mode change to am automatically according to the next day not past day.

解决方案

try this code:

TimePickerFragment timePickerFragment = new TimePickerFragment();
            timePickerFragment.setOnTimeSetListener(new OnTimeSetListener() {
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    Calendar datetime = Calendar.getInstance();
                    Calendar c = Calendar.getInstance();
                    datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    datetime.set(Calendar.MINUTE, minute);
                    if (datetime.getTimeInMillis() >= c.getTimeInMillis()) {
                        //it's after current
                         int hour = hourOfDay % 12;
                    btnPickStartTime.setText(String.format("%02d:%02d %s", hour == 0 ? 12 : hour,
                            minute, hourOfDay < 12 ? "am" : "pm"));
                    } else {
                        //it's before current'
                        Toast.makeText(getApplicationContext(), "Invalid Time", Toast.LENGTH_LONG).show();
                    }
                }
            });
            timePickerFragment.show(getSupportFragmentManager(), "TIME");

it will show the timepicker dialog and if user select any time before current time... it will show invalid time..

EDIT You need to import:

import android.app.TimePickerDialog;
import android.app.Fragment;
import android.app.DialogFragment;
import java.util.Calendar;
import android.widget.TimePicker;
