这是FirstActivity：

  void handleBlogEditClick(){
       if (BlogDetailActivity.this!= null) {
            BlogDetailVO blogDetailVO=new BlogDetailVO(getArgs().getmId(),getArgs().getmName().toString(),getArgs().getmDescription().toString());
            blogDetailVO.mCoverPic.setmImageUrl(getArgs().getmImageUrl());
            Intent intent = new Intent(BlogDetailActivity.this, EditBlogActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
            intent.putExtra("blogDetailVO",blogDetailVO);
            startActivity(intent);
       }
    }

第二项活动：

mState = new EditBlogState();
Intent intent = getIntent();
BlogDetailVO blogDetailVO =(BlogDetailVO) intent.getParcelableExtra("blogDetailVO");
mState.mCoverPhotoStory.setmName(blogDetailVO.getmName());
mView.updateBlogTitle(mState.mCoverPhotoStory.getmName());

第一个和第二个活动代码中的其他内容与此无关，所以我分享了这么多

public class BlogDetailVO extends BlogFeedVO implements Parcelable{

    PhotoStoryVO mCoverPic;
    List<PhotoStoryVO> mPhotoStories;
    LocationVO mLocationVO;

    public BlogDetailVO(String mId, String mName, String mDescription) {
        super(mId, mName, mDescription);
    }

    protected BlogDetailVO(Parcel in) {
        super(in);

        mCoverPic = in.readParcelable(PhotoStoryVO.class.getClassLoader());
        mPhotoStories = in.createTypedArrayList(PhotoStoryVO.CREATOR);
        mLocationVO = in.readParcelable(LocationVO.class.getClassLoader());
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        super.writeToParcel(dest, flags);

        dest.writeParcelable(mCoverPic, flags);
        dest.writeTypedList(mPhotoStories);
        dest.writeParcelable(mLocationVO, flags);
    }

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

    public static final Creator<BlogDetailVO> CREATOR = new Creator<BlogDetailVO>() {
        @Override
        public BlogDetailVO createFromParcel(Parcel in) {
            return new BlogDetailVO(in);
        }

        @Override
        public BlogDetailVO[] newArray(int size) {
            return new BlogDetailVO[size];
        }
    };

    public PhotoStoryVO getmCoverPic() {
        return mCoverPic;
    }

    public void setmCoverPic(PhotoStoryVO mCoverPic) {
        this.mCoverPic = mCoverPic;
    }


    public List<PhotoStoryVO> getmPhotoStories() {
        return mPhotoStories;
    }

    public void setmPhotoStories(List<PhotoStoryVO> mPhotoStories) {
        this.mPhotoStories = mPhotoStories;
    }

    public LocationVO getmLocationVO() {
        return mLocationVO;
    }

    public void setmLocationVO(LocationVO mLocationVO) {
        this.mLocationVO = mLocationVO;
    }
}

我是android新手。很抱歉，如果这个问题很愚蠢。但我真的被困住了，需要帮助。我正在将BlogDetailVO类对象发送到另一个活动。第二行显示为null。所以我不能用这种方式来填充价值吗？最终它崩溃了。

BlogDetailVO blogDetailVO=new BlogDetailVO(getArgs().getmId(),getArgs().getmName().toString(),getArgs().getmDescription().toString());
blogDetailVO.mCoverPic.setmImageUrl(getArgs().getmImageUrl()); //this gives the error!!
Intent intent = new Intent(BlogDetailActivity.this, EditBlogActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.putExtra("blogDetailVO",blogDetailVO);  startActivity(intent);

那么如何将值填充到BlogDtailVO类以便将其发送到其他活动？ 在接收活动中，我以这种方式接收它：

 Intent intent = getIntent();
 BlogDetailVO blogDetailVO =(BlogDetailVO) intent.getParcelableExtra("blogDetailVO");
