android：TimePickerDialog阻止用户选择过去的时间，并且可以选择带有新日期的未来时间

试试这个代码：

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

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;

这是一个很好的例子
