java - 使用 Activity 类中的方法

Question

我正在扩展 BroadcastReceiver 类，但在给定的函数中我需要使用 getIntent() 函数，它是 Activity 类 的一部分。我应该如何使用此功能，因为我只能扩展一个类。

public class AlarmReceiver extends BroadcastReceiver {

AudioManager audioControl;
Bundle extras;
int startHour,startMinute;

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    SimpleDateFormat sdf = new SimpleDateFormat("EEEE");
    Date d = new Date();
    String day = sdf.format(d);
    Calendar c = Calendar.getInstance();
    audioControl = (AudioManager) context
            .getSystemService(Context.AUDIO_SERVICE);
    extras = getIntent().getExtras();
    if(extras!=null){
        startHour = extras.getInt("startHour");
        startMinute = extras.getInt("startMinute");
    }

    int minute = c.get(Calendar.MINUTE);
    int hour = c.get(Calendar.HOUR_OF_DAY);
    if(day.equals("Thursday")){
        if(hour==startHour){
            if(minute==startMinute){
                audioControl.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
            }
        }
    }

}

编辑:我的主要类(class):

public class Settings extends Activity implements View.OnClickListener {


private PendingIntent pendingIntent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.setting);
    Intent alarmIntent = new Intent(Settings.this, AlarmReceiver.class);
    alarmIntent.putExtra("day", "Tuesday");
    pendingIntent = PendingIntent.getBroadcast(Settings.this, 0, alarmIntent, 0);
    alarmRepeat();
}
  public void alarmRepeat(){
    Calendar cal = Calendar.getInstance();
    AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    manager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 1000, pendingIntent);
}

只需检查您的 onReceive() 方法

@Override                                      
public void onReceive(Context context, Intent intent) {
                                              ^^^^^
    //you already have an instance of Intent object
    //just use it like this.
    Bundle extras=intent.getExtras();
}
