Get alarm infomation | 易学教程

I am implementing an application in which I have to display alarm info (day, time..) if it is available. Is there anybody know how to access to alarm info? Thanks so much

Try something like this

final String tag_alarm = "tag_alarm";
Uri uri = Uri.parse("content://com.android.alarmclock/alarm")
Cursor c = getContentResolver().query(uri, null, null, null, null);
Log.i(tag_alarm, "no of records are" + c.getCount());
Log.i(tag_alarm, "no of columns are" + c.getColumnCount());
if (c != null) {
    String names[] = c.getColumnNames();
    for (String temp : names) {
        System.out.println(temp);
    }
    if (c.moveToFirst()) {
        do {
            for (int j = 0; j < c.getColumnCount(); j++) {
                Log.i(tag_alarm, c.getColumnName(j);
                        + " which has value " + c.getString(j));
            }
        } while (c.moveToNext());
    }
}

Result: Finally, I can retrieve alarm information by using Curious's answer as above. Moreover, when I explored Deskclock app in /packages/apps/ I found one more way to get next alarm format (I used this way to display alarm info on my LockScreen because it is more simple than Curious's one :) )

String nextAlarm = Settings.System.getString(getContentResolver(), 
                       Settings.System.NEXT_ALARM_FORMATTED);
if(TextUtils.isEmpty(nextAlarm) {
     Log.v(TAG, "nextAlarm is empty");
} else {
     Log.v(TAG, "nextAlarm is :" + nextAlarm);
}

The next alarm format like this:

Sat 09:00

The disadvantage point is that it can only run in system environment (you have to embed them to Android source -> build it and run by image file).
