为捆绑包赋值时的ClassCastException

Question

加载捆绑包时出现错误。我已经检查了所有的初始化和类型转换，但无法解决这个问题。请参阅参考资料：

Bundle bundle = getIntent().getExtras();
if (bundle.containsKey("MEASUREMENT_DATA")) {
    body_scaleMeasurement = bundle.getParcelable("MEASUREMENT_DATA");
    evaluate_info();
}

body _scaleMeasurement的代码

package model;

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

import com.google.gson.annotations.SerializedName;

public class BodyScaleMeasurement implements Parcelable {

    @SerializedName("id")
    private String id;
    @SerializedName("client_platform_version")
    private String client_platform_version;
    @SerializedName("client_build_number")

    @SerializedName("client_platform_data")
    private Client_platform_data client_platform_data;
    @SerializedName("ble_device_data")
    private Ble_device_data ble_device_data;


    private transient boolean is_synchronized;

    public BodyScaleMeasurement() {
    }

    public BodyScaleMeasurement(String id, String client_platform_version, int client_build_number,  Client_platform_data client_platform_data, Ble_device_data ble_device_data, boolean is_synchronized) {
        this.id = id;
        this.client_platform_version = client_platform_version;
        this.client_build_number = client_build_number;

        this.client_platform_data = client_platform_data;
        this.ble_device_data = ble_device_data;

        this.is_synchronized = is_synchronized;

    }

    public boolean is_synchronized() {
        return is_synchronized;
    }

    public void setIs_synchronized(boolean is_synchronized) {
        this.is_synchronized = is_synchronized;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getClient_platform_version() {
        return client_platform_version;
    }

    public void setClient_platform_version(String client_platform_version) {
        this.client_platform_version = client_platform_version;
    }

    public int getClient_build_number() {
        return client_build_number;
    }

    public void setClient_build_number(int client_build_number) {
        this.client_build_number = client_build_number;
    }



    public Client_platform_data getClient_platform_data() {
        return client_platform_data;
    }

    public void setClient_platform_data(Client_platform_data client_platform_data) {
        this.client_platform_data = client_platform_data;
    }

    public Ble_device_data getBle_device_data() {
        return ble_device_data;
    }

    public void setBle_device_data(Ble_device_data ble_device_data) {
        this.ble_device_data = ble_device_data;
    }



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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(this.id);
        dest.writeString(this.client_platform_version);
        dest.writeInt(this.client_build_number);

        dest.writeParcelable(this.client_platform_data, 0);
        dest.writeParcelable(this.ble_device_data, 0);

        dest.writeByte(is_synchronized ? (byte) 1 : (byte) 0);
    }

    protected BodyScaleMeasurement(Parcel in) {
        this.id = in.readString();
        this.client_platform_version = in.readString();
        this.client_build_number = in.readInt();

        this.client_platform_data = in.readParcelable(Client_platform_data.class.getClassLoader());
        this.ble_device_data = in.readParcelable(Ble_device_data.class.getClassLoader());

        this.is_synchronized = in.readByte() != 0;
    }

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

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

这就是我得到的错误。请参考我附上的图片。

Answer 1

这是因为我将其他变量的类型从double更改为int。虽然这是意想不到的，但我自己并不理解它。我恢复了完成转换时所做的更改。

此外，转换后的值也发生了变化。例如:如果我发送50来捆绑一个密钥。它被设置为某个负整数。

Answer 2

有没有可能是Client_platform_data implements Parcelable和Parcelable.Creator<Ble_device_data>？
