私は意図経由<strong></strong>活動から<strong>B</strong>活動にParcelableオブジェクトを渡すためにしようとしています意図

Question

経由Parcelableを置く：B活動に

Intent intent = new Intent (A.this, B.class); 

intent.putExtra ("post", mypost); // where post implements Parcelable` 

私は、このようにポストオブジェクトを得た：

Post myPost = getIntent().getParcelableExtra("post"); 

Bで活性myPostオブジェクトフィールドが混合され、例えばポストモデルにpostTextフィールドとpostDateフィールドがあり、Bアクティビティのこのフィールドの値は混在しています。

なぜこのようなことが起こりますか？私のモデルクラスの外観は、次のことを好き：

publicクラスのポストはParcelable、シリアライズ{

private static final long serialVersionUID = 2L; 

@SerializedName("author") 
private User author; 

@SerializedName("comments_count") 
private String commentsCount; 

@SerializedName("image") 
private String imageToPost; 

@SerializedName("parent_key") 
private String parentKey; 

@SerializedName("created_date") 
private String postDate; 

@SerializedName("id") 
private String postId; 

@SerializedName("text") 
private String postText; 

@SerializedName("title") 
private String postTitle; 

@SerializedName("shared_post_id")

@SerializedName("url")

@SerializedName("video")

public Post() {

public Post(Parcel in) { 
    author = (User) in.readValue(getClass().getClassLoader()); 
    commentsCount = in.readString(); 
    imageToPost = in.readString();

    dest.writeString(postTitle); 
    dest.writeString(sharedPostId); 
    dest.writeString(urlToPost); 
    dest.writeString(videoToPost);

}

Answer 1

がdescribeContentsとwriteToParcelを追加実装しています。

例：

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

@Override 
public void writeToParcel(Parcel dest, int flags) { 
    dest.writeString(name); 
    dest.writeString(email); 
    dest.writeString(pass); 
    dest.writeFloat(amountPaid); 
    dest.writeString(url); 
    dest.writeInt(age); 
}
