Question

我有一个Post对象，我将其传递给intent：

Log.d("POST_IMAGE", post.image_url); http://localhost:8888/wordpress/wp-content/uploads/2016/06/yudikcflq9lsulgtwncn.jpg

final Intent intent = new Intent(); intent.setClass(host, PostDetail.class); intent.putExtra(PostDetail.EXTRA_POST, (Post) getItem(holder.getAdapterPosition())); host.startActivity(intent);

我的PostDetail活动中的OnCreate方法：

post = getIntent().getParcelableExtra(EXTRA_POST); Log.d("POST_IMAGE", post.image_url); ��S��http://localhost:8888/wordpress/wp-content/uploads/

检索到我的image_url后，我得到了这个奇怪的字符串，而不是��S��http://localhost:8888/wordpress/wp-content/uploads/

在我制作意图之前，图像字符串显示正常，但在传递之后，我得到一个格式错误的字符串。我的对象上的其他属性看起来很好。它只是这个变量。

我认为这是你的问题。你在writeToParcel（）

中有这个

if (comments == null) {
    dest.writeByte((byte) (0x00));
} else {
    dest.writeByte((byte) (0x01));
    dest.writeList(comments);
}
dest.writeString(image_url);

如果他们在那里，会添加评论列表，但如果没有，则跳过该列表。在创建者中，您总是加载列表。

.setBadge(existing.badge)
.setUserJob(existing.user_job)
.setComments(existing.comments)
.setImageUrl(existing.image_url);

你有没有想过看看这是否只发生在有评论的帖子上？
