android中对象Parcelable化

　　对象序列化找个东西我不知道怎么用。个人认为许多需要传递大对象的情况都可以避免掉。比如把多个acitivyt的内容写到一个activity中（找个好处还可以同时可以finish掉许多activity哦）。但是作为一个知识，还是写写了，也因为我n久没有更新博客了。

　　介绍的话就不准备写了，还是代码简单：

　　

public class ImageEntity implements Parcelable{
    String name;
    String path;
    String path1; // first path, default path . replace with selector
    String path2; // second path, default path
    int id;
    boolean isSelected;
    
    public ImageEntity(String path) {
        this.name = path;
        this.path = this.path1 = this.path2 = path;
        this.isSelected = false;
    }
    public ImageEntity(String path1, String path2){
        this.name = path1;
        this.path1 = path1;
        this.path2 = path2;
    }
    public ImageEntity(String name, String path1, String path2){
        this.name = name;
        this.path1 = path1;
        this.path2 = path2;
    }
    public ImageEntity(String name, int id){
        this.name = name;
        this.path = "";
        this.id = id;
        this.isSelected = false;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPath() {
        return path;
    }
    public void setPath(String path) {
        this.path = path;
    }
    public String getPath1() {
        return path1;
    }
    public void setPath1(String path1) {
        this.path1 = path1;
    }
    public String getPath2() {
        return path2;
    }
    public void setPath2(String path2) {
        this.path2 = path2;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public boolean isSelected() {
        return isSelected;
    }
    public void setSelected(boolean isSelected) {
        this.isSelected = isSelected;
    }
    
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeString(path);
        dest.writeInt(id);
        dest.writeByte((byte) (isSelected ? 1 : 0));     //if isSelected == true, byte == 1
    }
    public static final Parcelable.Creator<ImageEntity> CREATOR = new Parcelable.Creator<ImageEntity>(){

        @Override
        public ImageEntity createFromParcel(Parcel source) {
            
            return new ImageEntity(source);
        }

        @Override
        public ImageEntity[] newArray(int size) {
            // TODO Auto-generated method stub
            return new ImageEntity[size];
        }
        
    };
    private ImageEntity(Parcel parcel){
        name = parcel.readString();
        path = parcel.readString();
        id = parcel.readInt();
        isSelected = parcel.readByte() == 1;     //isSelected == true if byte == 1
    }
}

　　还又一个没完：
