Question

我已使用Parcelable将对象传递给新活动，并将其写入writeToParcel。我相信该对象已被转移，因为我可以使用.toString（）但它没有任何相关的方法。我使用了这个链接：http://shri.blog.kraya.co.uk/2010/04/26/android-parcel-data-to-pass-between-activities-using-parcelable-classes/我的代码运行，但我希望能够使用a.clubName()或其他一些能够访问这些详细信息，或者我试图错误地访问详细信息或我还没有完全正确的设置。

感谢您的帮助。

这是我的俱乐部课程，它将详细信息与包裹相关联

public class Clubs implements Parcelable{   
        //lots of variables defining things such as clubName, address etc.

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator(){
                public Clubs createFromParcel(Parcel in) {
                    return new Clubs(in); }  
                public Clubs[] newArray(int size) {
                    return new Clubs[size]; } 
                };  

        private void readFromParcel(Parcel in) {  
            clubName = in.readString(); 
            address = in.readString(); 
            postcode = in.readString(); 
            contactName = in.readString(); 
            contactPhone = in.readString(); 
            date = in.readString(); 
            eventType = in.readString(); 
            scrutTime = in.readString(); 
            startTime = in.readString(); 
            eventName = in.readString(); 
            week = in.readString(); 
        }
    @Override   
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(clubName); 
        dest.writeString(address);
        dest.writeString(postcode);
        dest.writeString(contactName);
        dest.writeString(contactPhone);
        dest.writeString(date);
        dest.writeString(eventType);
        dest.writeString(scrutTime);
        dest.writeString(startTime);
        dest.writeString(eventName);
        dest.writeString(week);
    }

    public Clubs(Parcel in) { readFromParcel(in); }

这是我的onItemClick方法，它启动应该通过

发送对象的新活动

public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
                Clubs mymeeting = db.get(map.get(position));
                Intent i = new Intent(ListSample.this, DynamicEvents.class);
                i.putExtra("mymeeting", mymeeting);
                startActivity(i);
            }

        });

这是我希望能够将详细信息写入

的课程

public class DynamicEvents extends Activity
{
  protected void onCreate(Bundle savedInstanceState)
  {
      super.onCreate(savedInstanceState);
        Bundle b = getIntent().getExtras();
        // Create the text view
        TextView textView = new TextView(this);
        textView.setTextSize(20);
        Object a = b.getParcelable("mymeeting");
        textView.setText(a.toString());

        // Set the text view as the activity layout
        setContentView(textView);
  } 
}

Answer 1

您需要将parcelable转换为正确的类类型。

Parcelable parcelable = b.getParcelable("mymeeting");
if(parcelable instanceof Clubs) {
   Clubs clubs = (Clubs) parcelable;
}

无法访问我的Parcelable对象方法
