android studio设置特定小时和分钟的声音闹钟

// 获取闹钟管理器实例
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

// 创建一个Intent，用于触发闹钟时启动特定的组件（例如广播接收器）
Intent alarmIntent = new Intent(this, MyAlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);

// 设置闹钟的触发时间
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, desiredHour); // 设置小时
calendar.set(Calendar.MINUTE, desiredMinute); // 设置分钟

// 设置闹钟
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
