Java android java.lang.RuntimeException : Parcelable encountered IOException writing serializable object

Question

我想在完成 Activity 的结果中放置一个对象列表我创建了一个类，如下所示:

 public class Vals implements Serializable {
    public ArrayList<RowBean> data;

    public Vals(ArrayList<RowBean> data) {
        this.data = data;
    }
}

下一步 Activity ( fragment )我在完成 Activity 后执行了此操作:

private void finishWithResult() {
    Bundle conData = new Bundle();
    conData.putString("param_result", counter + "");
    Intent intent = new Intent();
    intent.putExtras(conData);
    ArrayList<RowBean> rows = new ArrayList<>();
    for(RowBean row : rowBeen){
        if(row.isSelected())
            rows.add(row);
    }
    intent.putExtra(ROW_BEAN_DATA, new Vals(rows));
    getActivity().setResult(RESULT_OK, intent);
    getActivity().finish();
}

在控制台中我有:

FATAL EXCEPTION: main
Process: com.maps, PID: 10222 java.lang.RuntimeException:

这是 onActivityResult :

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case 90:
                if (resultCode == RESULT_OK) {
                    Bundle res = data.getExtras();
                    String result = res.getString("param_result");
                    int count = Integer.parseInt(result);
                    if (count != 1)
                        tvChooseObjects.setText("Wybrano " + count + " obiekty");
                    else
                        tvChooseObjects.setText("Wybrano " + count + " obiekt");
                    rowBeen = ((Vals) getIntent().getSerializableExtra(FragmentListOfAllObjetsToReportActivity.ROW_BEAN_DATA)).data;

                    Toast.makeText(getApplicationContext(), rowBeen.size() + " " , Toast.LENGTH_LONG).show();

                }
                break;
        }

尝试在 Vals 和 RawBean 类中用 Parcelable 替换 Serializable 实现

将 *onActivityResult** 中的 getSerializableExtra 替换为 getParcelableExtra

Vals.java

 public class Vals implements Serializable, Parcelable {
    public ArrayList<RowBean> data;

    public Vals(ArrayList<RowBean> data) {
        this.data = data;
    }

    protected Vals(Parcel in) {
        if (in.readByte() == 0x01) {
            data = new ArrayList<RowBean>();
            in.readList(data, RowBean.class.getClassLoader());
        } else {
            data = null;
        }
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        if (data == null) {
            dest.writeByte((byte) (0x00));
        } else {
            dest.writeByte((byte) (0x01));
            dest.writeList(data);
        }
    }

    @SuppressWarnings("unused")
    public static final Parcelable.Creator<Vals> CREATOR = new Parcelable.Creator<Vals>() {
        @Override
        public Vals createFromParcel(Parcel in) {
            return new Vals(in);
        }

        @Override
        public Vals[] newArray(int size) {
            return new Vals[size];
        }
    };
}

RawBean.java

public class RowBean implements Serializable, Parcelable {

    public String title;
    public boolean selected;

    public RowBean(){
    }

    public boolean isSelected() {
        return selected;
    }

    public void setSelected(boolean selected) {
        this.selected = selected;
    }

    public RowBean(boolean selected, String title) {
        this.selected = selected;
        this.title = title;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    protected RowBean(Parcel in) {
        title = in.readString();
        selected = in.readByte() != 0x00;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(title);
        dest.writeByte((byte) (selected ? 0x01 : 0x00));
    }

    @SuppressWarnings("unused")
    public static final Parcelable.Creator<RowBean> CREATOR = new Parcelable.Creator<RowBean>() {
        @Override
        public RowBean createFromParcel(Parcel in) {
            return new RowBean(in);
        }

        @Override
        public RowBean[] newArray(int size) {
            return new RowBean[size];
        }
    };
}
