从RecyclerView适配器内部访问AlarmManager

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;

private AlarmManager alarmManager;

public MyAdapter(Context context) {
    alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
}

public void setAlarm(Context context, long triggerTimeInMillis) {
    Intent intent = new Intent(context, MyAlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
    
    // 设置定时任务
    alarmManager.set(AlarmManager.RTC_WAKEUP, triggerTimeInMillis, pendingIntent);
}

long triggerTimeInMillis = System.currentTimeMillis() + 10000; // 10秒后触发
setAlarm(context, triggerTimeInMillis);
