Как установить будильник в Android?

Question

Ниже приведен мой код. Любое тело, пожалуйста, скажите мне, почему оно не работает. Я узнал это из этого урока Но это не работает, любая помощь будет заметна.

Мой код

import java.util.Calendar;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.ListActivity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Toast;


public class Notify extends Activity {
    Button btn;

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.nit);
        Calendar cal=Calendar.getInstance();
        cal.set(Calendar.MONTH,6);
        cal.set(Calendar.YEAR,2011);
        cal.set(Calendar.DAY_OF_MONTH,29);
        cal.set(Calendar.HOUR_OF_DAY,17);
        cal.set(Calendar.MINUTE,30);

        //String[] dude=new String[] {"nitin","avi","aman","rahul","pattrick","minkle","manmohan","nitin","nitin"};

        //setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1,dude));
        //getListView().setTextFilterEnabled(true);

        //String[] dude1=new String[] {"nitin","avi","aman","rahul","pattrick","minkle","manmohan"};

        Intent intent = new Intent(this, Mote.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),pendingIntent );
        Toast.makeText(this, "Alarm worked.", Toast.LENGTH_LONG).show();
    }

}

и мой класс приемника

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class Mote extends BroadcastReceiver{

    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
        int icon = R.drawable.icon;
        CharSequence tickerText = "Hello you have to take medicine I am Nitin Sharma";
        long when = System.currentTimeMillis();

        //Notification notification = new Notification(icon, tickerText,when );

        CharSequence contentTitle = "My notification";
        CharSequence contentText = "Hello World!";


        //notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        final int NOTIF_ID = 1234;
        NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);
        // Notification note = new Notification(R.drawable.face,"NEW ACTIVITY", System.currentTimeMillis());
        Intent notificationIntent = new Intent(context, Alset.class);
        PendingIntent contentIntent = PendingIntent.getActivity(context,0, notificationIntent, 0);
        Notification notification = new Notification(icon, tickerText,when );
        //Notification notification1 = new Notification(R.drawable.icon, "Wake up alarm", System.currentTimeMillis());
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        notification.flags = Notification.FLAG_INSISTENT;
        notification.defaults |= Notification.DEFAULT_SOUND;
        //notification.setLatestEventInfo(context, "My Activity", "This will runs on button click", contentIntent);
        notofManager.notify(NOTIF_ID,notification);

        //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
        //notification.setLatestEventInfo(context, "Context Title", "Context text", contentIntent);
        //notification.flags = Notification.FLAG_INSISTENT;
    }

Answer 1

Я думаю, вы хотите установить будильник на 26 июня, а не на 26 июля. Если это так, то измените cal.set(Calendar.MONTH,6); на cal.set(Calendar.MONTH,5);, потому что месяцы начинаются с нуля. если вы намереваетесь сработать будильник 26 июля, то ожидается, что будильник сработает, когда дата-время 26 июля 2011 года, 17:30

1.Добавьте это в файл манифеста

 <receiver android:name=".MyAlarmReciever">
            <intent-filter>
                <action android:name="com.example.helloandroid.alarms" />
            </intent-filter>
        </receiver>        

2. сделать деятельность

        public class AlrmActivity extends BaseAcitivity {
   
           TimePicker myTimePicker;
           Button buttonstartSetDialog;
           TextView textAlarmPrompt;
   
           TimePickerDialog timePickerDialog;
   
           final static int RQS_1 = 1;
   
           @Override
           protected void onCreate(Bundle savedInstanceState) {
               super.onCreate(savedInstanceState);
               setContentView(R.layout.activity_alrm);
   
               textAlarmPrompt = (TextView)findViewById(R.id.alarmprompt);
   
               buttonstartSetDialog = (Button)findViewById(R.id.startSetDialog);
               buttonstartSetDialog.setOnClickListener(new View.OnClickListener(){
   
                   @Override
                   public void onClick(View v) {
                       textAlarmPrompt.setText("");
                       openTimePickerDialog(false);
   
                   }});
   
   
           }
   
           private void openTimePickerDialog(boolean is24r){
               Calendar calendar = Calendar.getInstance();
   
               timePickerDialog = new TimePickerDialog(
                       AlrmActivity.this,
                       onTimeSetListener,
                       calendar.get(Calendar.HOUR_OF_DAY),
                       calendar.get(Calendar.MINUTE),
                       is24r);
               timePickerDialog.setTitle("Set Alarm Time");
   
               timePickerDialog.show();
   
           }
           TimePickerDialog.OnTimeSetListener onTimeSetListener
                   = new TimePickerDialog.OnTimeSetListener(){
   
               @Override
               public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
   
                   Calendar calNow = Calendar.getInstance();
                   Calendar calSet = (Calendar) calNow.clone();
   
                   calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
                   calSet.set(Calendar.MINUTE, minute);
                   calSet.set(Calendar.SECOND, 0);
                   calSet.set(Calendar.MILLISECOND, 0);
   
                   if(calSet.compareTo(calNow) <= 0){
                       //Today Set time passed, count to tomorrow
                       calSet.add(Calendar.DATE, 1);
                   }
   
                   setAlarm(calSet);
               }};
   
           private void setAlarm(Calendar targetCal){
   
               textAlarmPrompt.setText(
                       "\n\n***\n"
                               + "Alarm is set@ " + targetCal.getTime() + "\n"
                               + "***\n");
   
               Intent intent = new Intent(getBaseContext(), MyAlarmReciever.class);
               PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
               AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
               alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent);
   
           }
   
       }
   

3. XML-файл включает

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="hello" />
        <Button
            android:id="@+id/startSetDialog"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Set Target Time"/>
        <TextView
            android:id="@+id/alarmprompt"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

        Vibrator v;
        Context ct;
        String  title;


        @Override

    //        }

        }


        public void Notification(Context context, String message) {

Answer 3

Вы установили приемник в своем файле манифеста?Как то так

<receiver  android:process=":remote" android:name=".Mote"></receiver>

Answer 4

надеюсь, что это поможет

@Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                Calendar calNow = Calendar.getInstance();
                Calendar calSet = (Calendar) calNow.clone();

                calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
                calSet.set(Calendar.MINUTE, minute);
                calSet.set(Calendar.SECOND, 0);
                calSet.set(Calendar.MILLISECOND, 0);

                if(calSet.compareTo(calNow) <= 0){
                    //Today Set time passed, count to tomorrow
                    calSet.add(Calendar.DATE, 1);
                }

                setAlarm(calSet);
            }};

        private void setAlarm(Calendar targetCal){

            textAlarmPrompt.setText(
                    "\n\n***\n"
                    + "Alarm is set@ " + targetCal.getTime() + "\n"
                    + "***\n");

            Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
            AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    //      alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent);
        }
