我想在我的 android 项目中实现一个日程安排功能。所以我在谷歌上搜索了一个警报管理器程序，但我无法解决问题。
我想用用户确定的自定义时间设置闹钟。我为服务和广播接收器编写了 2 个类。但是警报是不正确的，例如我为警报设置了 2 分钟。但是应用程序任意是工作。例如 2 分钟或 3 或 5 或 1 分钟....
主要活动：
SharedPreferences preferences1 = getSharedPreferences("min", 0);
String min1 = preferences1.getString("minute", "");
if (min1.length() <= 0) {
s = 120000;
} else {
s = Long.parseLong(min1);
s = s * 60000;
}
t = new Timer();
// Set the schedule function and rate
t.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
// Called each time when 1000 milliseconds (1 second)
// (the period parameter)
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 10);
Intent intent = new Intent(CategoryListActivity.this,
Service_class.class);
PendingIntent pintent = PendingIntent.getService(
CategoryListActivity.this, 0, intent, 0);
AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), s, pintent);
Log.e("Timer", t.toString());
}
},
// Set how long before to start calling the TimerTask (in
// milliseconds)
0,
// Set the amount of time between each execution (in
// milliseconds)
s);
服务类.java：
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
dbflash = new DatabaseFlashCard(getApplicationContext());
db = dbflash.getReadableDatabase();
SharedPreferences preferences_notify = getSharedPreferences("notify", 0);
Calendar c = Calendar.getInstance();
String time_one = preferences_notify.getString("time_first", "");
String time_two = preferences_notify.getString("time_second", "");
int hour = c.get(Calendar.HOUR_OF_DAY);
if (time_one.length() <= 0) {
time_one = "21";
}
if (time_two.length() <= 0) {
time_two = "5";
}
int timeFirst = Integer.parseInt(time_one);
int timeSecond = Integer.parseInt(time_two);
if (hour < timeFirst && hour > timeSecond) {
// nothing
} else {
// notify and alert
preferences_language = getSharedPreferences("language_sql", 0);
editor_language = preferences_language.edit();
String language = preferences_language.getString("language", "");
String sql="SELECT * FROM " + dbflash.TABLE
+ " where hide='0' ORDER BY RANDOM() LIMIT 1";
if(language.length()>0)
{
if(language.equalsIgnoreCase("0"))
{
sql="SELECT * FROM " + dbflash.TABLE
+ " where hide='0' ORDER BY RANDOM() LIMIT 1";
}
else
{
sql="SELECT * FROM " + dbflash.TABLE
+ " where ids="+language+" and hide='0' ORDER BY RANDOM() LIMIT 1";
}
Cursor cursors = db.rawQuery(sql, null);
for (int i = 0; i < cursors.getCount(); i++) {
cursors.moveToNext();
ID = cursors.getString(cursors.getColumnIndex("ID"));
farsi = cursors.getString(cursors.getColumnIndex("farsi"));
english = cursors.getString(cursors.getColumnIndex("english"));
question = cursors
.getString(cursors.getColumnIndex("question"));
count = cursors.getString(cursors.getColumnIndex("count"));
}
preferences_status = getSharedPreferences("notify_status", 0);
String status = preferences_status.getString("status", "");
SharedPreferences.Editor editor_status;
editor_status = preferences_status.edit();
if (status.length() <= 0) {
status="1";
editor_status.putString("status", "1");
editor_status.commit();
Log.e("Notification Status ", "Enable Now..for First");
} else if(status.equalsIgnoreCase("0")) {
Log.e("Notification Status ", "disable");
}
else
{
Log.e("Notification Status ", "enable");
if (english==null || english=="") {
} else {
SharedPreferences preferences = getSharedPreferences("music", 0);
String address=preferences.getString("address", "");
if(address.length()<=0)
{
mp = MediaPlayer.create(getApplicationContext(), R.raw.ring);
mp.start();
}
else
{
mp = MediaPlayer.create(getApplicationContext(),Uri.parse(address));
mp.start();
}
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent contentIntent = new Intent(this,
QuestionActivity.class);
contentIntent.putExtra("ID", ID);
contentIntent.putExtra("english", english);
contentIntent.putExtra("farsi", farsi);
contentIntent.putExtra("count", count);
contentIntent.putExtra("question", question);
Notification notification = new Notification(
R.drawable.icon, "یاد آوری",
System.currentTimeMillis());
notification.setLatestEventInfo(this, english, "",
PendingIntent.getActivity(this.getBaseContext(), 0,
contentIntent,
PendingIntent.FLAG_CANCEL_CURRENT));
notification.flags = Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(SIMPLE_NOTFICATION_ID,
notification);
}
}
}
}
return START_STICKY;
}
和我的接收者
public class Myreceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent serviceLauncher = new Intent(context, Service_class.class);
context.startService(serviceLauncher);
}
安卓清单：
<service android:name=".Service_class" />
<receiver
android:name="com.pttat.flashcard.services.Myreceiver"
android:process=":remote" />
如何更改我的代码以解决我的问题？
我需要在 Oncreate 中更改呼叫警报管理器吗？
谢谢
