Android之Parcelable使用

必須實現Parcelable：且屬性的writeXXX與readXXX必須順序一一對應。

public class BaseModel implements Parcelable {    public long mID;    public long getmID() {        return mID;    }    public void setmID(long mID) {        this.mID = mID;    }    @Override    public int describeContents() {        // TODO Auto-generated method stub        return 0;    }    @Override    public void writeToParcel(Parcel dest, int flags) {        // TODO Auto-generated method stub         dest.writeLong(mID);     }    public static final Parcelable.Creator<BaseModel> CREATOR = new Parcelable.Creator<BaseModel>() {           //重寫Creator                          @Override                  public BaseModel createFromParcel(Parcel source) {                       BaseModel p = new BaseModel();                       p.mID = source.readLong();                     return p;                   }                             @Override                  public BaseModel[] newArray(int size) {                       // TODO Auto-generated method stub                       return new BaseModel[size];                  }               };                     }

發送廣播：

public static void sendList(Context mContext,ArrayList<MusicModel> list){        Intent intent = new Intent("PLAYLIST");                intent.putParcelableArrayListExtra(MediaService.MediaServicePlayList, list);                mContext.sendBroadcast(intent);    }

接收廣播：

public class PlayListReceiver extends BroadcastReceiver{        @Override        public void onReceive(Context context, Intent intent) {                        mList = intent.getParcelableArrayListExtra(MediaServicePlayList);                    }            }

playListReceiver = new PlayListReceiver();        registerReceiver(playListReceiver,new IntentFilter("PLAYLIST"));
