我正在开发一个应用程序，我每天存储时间表，例如每天会有 6 个时间表，但每天的时间会有所不同，我已将 Scheduled 和 sqlite 中的时间存储在表中，现在我想做这些时间表的警报，我应该怎么做。 闹钟例如周日上午 9:30、上午 10:40、上午 11:00、中午 12 点、下午 4 点、下午 5 点，周一上午 7 点、上午 8 点等。 我正在使用此代码在特定时间设置闹钟
calSet.set(Calendar.DAY_OF_WEEK, week);
calSet.set(Calendar.HOUR_OF_DAY, hour);
calSet.set(Calendar.MINUTE, minuts);
calSet.set(Calendar.SECOND, 0);
calSet.set(Calendar.MILLISECOND, 0);
alarmManager.set(AlarmManager.RTC_WAKEUP,
calSet.getTimeInMillis(), 1 * 60 * 60 * 1000, pendingIntent);
如果你不使用SQlite那么这很简单， 您可以将 PendingIntent 与不同的请求代码一起使用。
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), requestcode, intent, 0);
requestcode+=1;
我已经发布了 3 个课程，使用这些课程你可以得到你的任务。
SetAlarms.java类实际设置闹钟
public class SetAlarms {
Context c;
String SaveStateVal;
public SetAlarms(Context c) {
this.c = c;
}
public void AlarmSet(int i, Calendar targetCal) {
Intent intent = new Intent(c, AlarmReciever.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(c, i, intent,
0);
AlarmManager alarmManager = (AlarmManager) c
.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
pendingIntent);
}
}
这是 AlarmReciever.java 类，当闹钟来临时，这个类会被调用
public class AlarmReciever extends BroadcastReceiver {
MediaPlayer mP;
@Override
public void onReceive(Context context, Intent intent) {
// /** Play sound */
mP = MediaPlayer.create(context, R.raw.tn);
mP.start();
// Show the toast like in above screen shot
Toast.makeText(context, "Congratulation Alarm is Triggered",
Toast.LENGTH_LONG).show();
}
}
Mainactivity.java类您可以简单地向警报类提供值（时间），使用Timepacker您可以设置警报。
public class MainActivity extends Activity implements OnClickListener {
TimePickerDialog tPickerDialog;
SharedPreferences StatPref;
TextView tvtime, sttime;
Button setTim, getRec;
SetAlarms ar;
String str;
int Count = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
StatPref = getSharedPreferences("mfile", Context.MODE_PRIVATE);
reference();
tvtime.setText(getStr());
setTim.setOnClickListener(this);
sttime.setOnClickListener(this);
getRec.setOnClickListener(this);
}
private void reference() {
ar = new SetAlarms(this);
sttime = (TextView) findViewById(R.id.sttime);
getRec = (Button) findViewById(R.id.updtTime);
tvtime = (TextView) findViewById(R.id.tim);
tvtime.setText(getStr());
setTim = (Button) findViewById(R.id.sctime);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.sctime:
openTimePickerDialog(false);
tvtime.setText(getStr());
break;
case R.id.sttime:
openTimePickerDialog(false);
break;
case R.id.updtTime:
tvtime.setText(getStr());
break;
}
}
private void openTimePickerDialog(boolean is24r) {
Calendar calendar = Calendar.getInstance();
tPickerDialog = new TimePickerDialog(MainActivity.this,
onTimeSetListener, calendar.get(Calendar.HOUR_OF_DAY),
calendar.get(Calendar.MINUTE), is24r);
tPickerDialog.setTitle("Set Alarm Time");
tPickerDialog.show();
}
OnTimeSetListener onTimeSetListener = new 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);
if (Count <= 6) {
ar.AlarmSet(Count, calSet);
str = "\n" + "Alarm " + Count + " Set " + calSet.getTime();
Editor editrr = StatPref.edit();
editrr.putString("ref" + Count, str);
editrr.commit();
Count++;
} else {
Toast.makeText(
MainActivity.this,
"Set 6 Alarms at Same Time Restart Your App",
Toast.LENGTH_SHORT).show();
}
}
};
private String getStr() {
str = StatPref.getString("ref1", "");
str = str + "\n" + StatPref.getString("ref2", "");
str = str + "\n" + StatPref.getString("ref3", "");
str = str + "\n" + StatPref.getString("ref4", "");
str = str + "\n" + StatPref.getString("ref5", "");
str = str + "\n" + StatPref.getString("ref6", "");
return str;
}
}
main.xml 对于 MainActivity.java 类，使用此 xml 作为布局

将闹钟时间保存在数据库中。 不要设置重复闹钟，只设置一个。 当您的第一个警报被触发时（当您通过广播接收器收到警报事件时）查询数据库，并设置下一个警报。
所以这个想法很简单——当你执行一个闹钟时，设置下一个闹钟。您必须实现如何找到下一个闹钟时间的逻辑。
