我想在android中分享图像。我检查了很多代码来做到这一点，但所有代码都使应用程序停止。logcat错误如下：

我认为问题不在于共享代码。从 stacktrace 你可以清楚地看到框架抱怨ImageItem类对象：

java.lang.RuntimeException: Parcel: unable to marshal value ir.whc.news.model.ImageItem@41884b00.

不知道怎么打包。显然，您ImageItem通过捆绑将对象作为参数传递给您的 DialogFragment （您的问题缺少此调用代码），并且要实现这一点，对象必须实现Parcelable接口。您ImageItem的 is 没有必需的代码，因此您需要添加它（请参阅如何使我的自定义对象成为 Parcelable？有关如何实现或使用哪些工具生成所需代码的信息）。或者，您可以使用 Parceler 等库为您执行此操作。

由于这条线，您正在崩溃

images = (ArrayList<ImageItem>) getArguments().getSerializable("images");

实际上，您的 ImageItem 既不是 Serializable 也不是 Parcelable ，您正试图将其对象作为参数发送到 bundle 中。为避免这种情况，请使用 Parcelable 接口实现 ImageItem 类。

public class ImageItem implements Parcelable{
    public static final Creator<ImageItem> CREATOR = new Creator<ImageItem>() {

        public ImageItem createFromParcel(Parcel in) {
            return new ImageItem(in);
        }

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

    public Contact(Parcel parcel) {
        _id = parcel.readInt();
        _description = parcel.readString();
        _thumb_path = parcel.readString();
        _largimage_path = parcel.readString();
    }

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

    @Override
    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeInt(_id);
        parcel.writeString(_description);
        parcel.writeString(_thumb_path);
        parcel.writeString(_largimage_path);
    }

    ...
    ...
}

现在发送您的 ImageItem 对象的数组列表，只需放

bundle.putParcelableArrayListExtra("images", imageItemList);

要检索此列表，您必须这样做，

images = (ArrayList<ImageItem>) getArguments().getParcelableArrayListExtra("images");

您需要将 ImageItem 类实现为Serializable.

public class ImageItem implements Serializable{

// Other stuff

}

希望这会帮助你。
