android - Android可打包readtypedlist内存不足错误

我一直在尝试调试此可包裹对象中发生的内存不足错误。
我真的很坚持这一点。我检查了订单，对我来说似乎正确。

import java.util.ArrayList;
import java.util.List;

import android.os.Parcel;
import android.os.Parcelable;

import com.intuch.interfaces.ListRow;

public class ProfileModel implements Parcelable{

    public String linkedinID;
    public String firstName;
    public String lastName;
    public String email;
    public String pictureURL;
    public String headline;
    public String industry;
    public String interests;

    public List<EducationModel> education = new ArrayList<EducationModel>();
    public List<PositionModel> position = new ArrayList<PositionModel>();

    public boolean introduceOthers;
    public boolean answerQuestions;
    public boolean beMentor;
    public boolean graduated;

    public ProfileModel () {
        education = new ArrayList<EducationModel>();
        position = new ArrayList<PositionModel>();
    }

    public ProfileModel (Parcel in) {
        this();
        readFromParcel(in);
    }

    @Override
    public int describeContents() {
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(linkedinID);
        dest.writeString(firstName);
        dest.writeString(lastName);
        dest.writeString(email);
        dest.writeString(pictureURL);
        dest.writeString(headline);
        dest.writeString(industry);
        dest.writeString(interests);

        dest.writeList(education);
        dest.writeList(position);

        boolean[] myBooleanArr = new boolean[4];
        myBooleanArr[0]=introduceOthers;
        myBooleanArr[1]=answerQuestions;
        myBooleanArr[2]=beMentor;
        myBooleanArr[3]=graduated;
        dest.writeBooleanArray(myBooleanArr);
    }

    public static final Parcelable.Creator<ProfileModel> CREATOR = new Parcelable.Creator<ProfileModel>() {

          public ProfileModel createFromParcel(Parcel source) {
             return new ProfileModel(source);
          }

          public ProfileModel[] newArray(int size) {
             return new ProfileModel[size];
          }

       };

        /*
        * Constructor calls read to create object
        */
       private void readFromParcel(Parcel in) {
          this.linkedinID = in.readString();
          this.firstName = in.readString();
          this.lastName = in.readString();
          this.email = in.readString();
          this.pictureURL = in.readString();
          this.headline = in.readString();
          this.industry = in.readString();
          this.interests = in.readString();

          in.readTypedList(education, EducationModel.CREATOR);
          in.readTypedList(position, PositionModel.CREATOR);

          boolean[] myBooleanArr = new boolean[4];
          in.readBooleanArray(myBooleanArr);

          introduceOthers=myBooleanArr[0];
          answerQuestions=myBooleanArr[1];
          beMentor=myBooleanArr[2];
          graduated=myBooleanArr[3];
       }

}

该错误在以下行中发生:

in.readTypedList(position, PositionModel.CREATOR);

这是我的其他 class :

教育模式:

import android.os.Parcel;
import android.os.Parcelable;

public class EducationModel implements Parcelable{
    public String degree;
    public String schoolName;
    public int graduated;

    private EducationModel(Parcel in) {
        degree = in.readString();
        schoolName = in.readString();
        graduated = in.readInt();
      }

    public EducationModel() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(degree);
        dest.writeString(schoolName);
        dest.writeInt(graduated);
    }


    public static final Parcelable.Creator<EducationModel> CREATOR = new Parcelable.Creator<EducationModel>() {
        public EducationModel createFromParcel(Parcel in) {
         return new EducationModel(in);
        }

        public EducationModel[] newArray(int size) {
         return new EducationModel[size];
        }
      };

}

PositionModel:

import android.os.Parcel;
import android.os.Parcelable;

public class PositionModel implements Parcelable{
    public String company;
    public String title;

    private PositionModel(Parcel in) {
        company = in.readString();
        title = in.readString();
      }

    public PositionModel() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(company);
        dest.writeString(title);
    }


    public static final Parcelable.Creator<PositionModel> CREATOR = new Parcelable.Creator<PositionModel>() {
        public PositionModel createFromParcel(Parcel in) {
         return new PositionModel(in);
        }

        public PositionModel[] newArray(int size) {
         return new PositionModel[size];
        }
      };

}

最佳答案

您使用通用的writeList方法将列表写出，但使用readTypedList调用将其读回。这些不兼容。检查文档readTypedList:

该列表必须事先通过具有相同对象类型的writeTypedList(List)写入。

使用类型列表可以使Parcel更加有效地使用内存，因为它不会将列表中每个对象的类型写入流中。因此，如果您尝试回读列表数据，就像它是用“类型化”写入的，而是写为通用列表一样，则包裹处理将获取意外的数据并导致其抛出。
