从活动中发送额外内容以广播接收者

Question

My application is about Reminders. After inserting the reminders into the SQLite database it is showing ID's correctly in the AddReminderActivity.java class correctly but it is returning ID=1 in the AlarmReciver.java class in the following code.

This is how I am putting extra

       Intent intent = new Intent(this, AlarmReciever.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
    intent.putExtra("reminderId", reminderId);
    PendingIntent pendingIntent = 
    PendingIntent.getBroadcast(this.getApplicationContext(), 5, intent, 0);

    AlarmManager mAlarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    assert mAlarmManager != null;
    mAlarmManager.set(AlarmManager.RTC_WAKEUP, milliSecondsFromDate, pendingIntent);

    Toast.makeText(this, "Alarm set at " + selectedDate + " " + timeInHrs, Toast.LENGTH_LONG).show();
    finish();

This is how i am getting extra

@Override
public void onReceive(Context context, Intent intent) {

    Long reminderId = intent.getLongExtra("reminderId", -1);
    mDatabaseHelper = new DatabaseHelper(context);
    Reminder reminder = mDatabaseHelper.getReminder(reminderId);

    Intent serviceIntent = new Intent(context, TTSService.class);
    if (reminder != null && !reminder.getText().isEmpty()) {
        serviceIntent.putExtra("reminderText", reminder.getText());
    }
    context.startService(serviceIntent);

    Toast.makeText(context, "AlarmReciever..", Toast.LENGTH_LONG).show();

}

Answer 1

Use This to getting extra

@Override
public void onReceive(Context context, Intent intent) {

    Long reminderId = intent.getExtras().getLong("reminderId", -1);
    mDatabaseHelper = new DatabaseHelper(context);
    Reminder reminder = mDatabaseHelper.getReminder(reminderId);

    Intent serviceIntent = new Intent(context, TTSService.class);
    if (reminder != null && !reminder.getText().isEmpty()) {
        serviceIntent.putExtra("reminderText", reminder.getText());
    }
    context.startService(serviceIntent);

    Toast.makeText(context, "AlarmReciever..", Toast.LENGTH_LONG).show();

}

In order for the "extras" to be set correctly, you need to use PendingIntent.FLAG_UPDATE_CURRENT in the call to getBroadcast() as follows:

PendingIntent pendingIntent = 
    PendingIntent.getBroadcast(this.getApplicationContext(), 5, intent,
        PendingIntent.FLAG_UPDATE_CURRENT);

Also, are you sure that reminderId is of type long or Long in the code where you call putExtra() ?
