下面我使用3个类
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.clendar);
time = ( TimePicker ) findViewById( R.id.tpEventTime );
date = ( DatePicker ) findViewById( R.id.dpEventDate );
title = ( EditText ) findViewById ( R.id.etEventTitle );
description = ( EditText ) findViewById ( R.id.etEventDescription );
header = ( TextView ) findViewById ( R.id.txtMenuHeader );
header.setText( R.string.calendar );
back = ( Button ) findViewById( R.id.tabs_back );
home = ( Button ) findViewById ( R.id.tabs_home );
back.setOnClickListener( this );
home.setOnClickListener( this );
//---Button view---
Button btnOpen = ( Button ) findViewById( R.id.btEventDone );
btnOpen.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
String strT = title.getText().toString();
String strDes = description.getText().toString();
// check if user did not input anything
if( strT.isEmpty() || strDes.isEmpty() ){
Toast.makeText( getBaseContext(), "You have blank fields!", Toast.LENGTH_SHORT ).show();
}
else{
//---use the AlarmManager to trigger an alarm---
AlarmManager alarmManager = ( AlarmManager ) getSystemService( ALARM_SERVICE );
//---get current date and time---
Calendar calendar = Calendar.getInstance();
//---sets the time for the alarm to trigger---
calendar.set( Calendar.YEAR, date.getYear() );
calendar.set( Calendar.MONTH, date.getMonth() );
calendar.set( Calendar.DAY_OF_MONTH, date.getDayOfMonth() );
calendar.set( Calendar.HOUR_OF_DAY, time.getCurrentHour() );
calendar.set( Calendar.MINUTE, time.getCurrentMinute() );
//---PendingIntent to launch activity when the alarm triggers---
Intent i = new Intent( CalendarEvent.this, DisplayNotification.class );
year = calendar.get( Calendar.YEAR );
month = calendar.get( Calendar.MONTH );
day = calendar.get( Calendar.DAY_OF_MONTH );
hour = calendar.get( Calendar.HOUR );
minute = calendar.get( Calendar.MINUTE );
int intMonth = month + 1;
String strMonth = "";
String strDay = "";
if(month < 10){
strMonth = "0" + intMonth;
}
if(day < 10){
strDay = "0" + day ;
}
//Date d = new Date(year, month, day);
//SimpleDateFormat dateFormatter = new SimpleDateFormat(
// "MM-dd-yyyy");
//String strDate = dateFormatter.format(d);
String strTitle = title.getText().toString();
String strDescription = description.getText().toString();
String strDate = strMonth + "-" + strDay + "-" + String.valueOf( year );
StringBuilder sb = new StringBuilder();
if(hour >= 12){
sb.append(hour-12).append( ":" ).append(minute).append(" PM");
}else{
sb.append(hour).append( ":" ).append(minute).append(" AM");
}
String strTime = sb.toString();
//---assign an ID of 1---
i.putExtra( "NotifID", notifID );
i.putExtra( "Title", strTitle );
i.putExtra( "Description", strDescription );
i.putExtra( "Date", strDate );
i.putExtra( "Time", strTime );
PendingIntent displayIntent = PendingIntent.getActivity(
getBaseContext(), notifID, i, 0 );
//---sets the alarm to trigger---
alarmManager.set( AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), displayIntent );
finish();
}
}
});
}
报警详情：
EditText title, description, date, time;
Button done;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.alarmdetails);
//---look up the notification manager service---
NotificationManager nm = ( NotificationManager )
getSystemService( NOTIFICATION_SERVICE );
title = ( EditText ) findViewById ( R.id.etDetailTitle );
description = ( EditText ) findViewById ( R.id.etDetailDescription );
date = ( EditText ) findViewById ( R.id.etDetailDate );
time = ( EditText ) findViewById ( R.id.etDetailTime );
done = ( Button ) findViewById ( R.id.btnAlarmDone );
done.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
finish();
}
});
//---cancel the notification---
nm.cancel( getIntent().getExtras().getInt( "NotifID" ) );
Date d = new Date();
SimpleDateFormat dateFormatter = new SimpleDateFormat(
"MM-dd-yyyy hh:mm");
String strDate = dateFormatter.format(d);
String strTitle = getIntent().getExtras().getString( "Title" );
String strDescription = getIntent().getExtras().getString( "Description" );
strDate = getIntent().getExtras().getString( "Date" );
String strTime = getIntent().getExtras().getString( "Time" );
title.setText( strTitle );
description.setText( strDescription );
date.setText( strDate );
time.setText( strTime );
}
}
显示通知：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//---get the notification ID for the notification;
// passed in by the NotifyActivity---
int notifID = getIntent().getExtras().getInt( "NotifID" );
String strTitle = getIntent().getExtras().getString( "Title" );
String strDescription = getIntent().getExtras().getString( "Description" );
String strDate = getIntent().getExtras().getString( "Date" );
String strTime = getIntent().getExtras().getString( "Time" );
//---PendingIntent to launch activity if the user selects
// the notification---
Intent i = new Intent( DisplayNotification.this, AlarmDetails.class );
i.putExtra( "NotifID", notifID );
i.putExtra( "Title", strTitle );
i.putExtra( "Description", strDescription );
i.putExtra( "Date", strDate );
i.putExtra( "Time", strTime );
PendingIntent detailsIntent =
PendingIntent.getActivity(this, 0, i, 0);
NotificationManager nm = ( NotificationManager )
getSystemService( NOTIFICATION_SERVICE );
Notification notif = new Notification(
R.drawable.ic_launcher,
"iHealthFirst: Notification!",
System.currentTimeMillis() );
CharSequence from = "iHealthFirst - New Notification";
CharSequence message = "This is your alert, click to view";
notif.setLatestEventInfo(this, from, message, detailsIntent);
notif.flags = Notification.FLAG_INSISTENT;
notif.defaults |= Notification.DEFAULT_SOUND;
//---100ms delay, vibrate for 250ms, pause for 100 ms and
// then vibrate for 500ms---
notif.vibrate = new long[] { 100, 250, 100, 500};
nm.notify( notifID, notif );
//---destroy the activity---
finish();
}
}
首次创建通知时，它可以工作。但是当我创建另一个时，之前的通知仍然显示。我怎样才能显示另一个通知？谢谢
