RecyclerView中删除项目后的重叠视图 [英] Overlap view after delete item in RecyclerView

问题描述

在RecyclerView中删除项目会导致视图重叠，例如此视频 链接

Removing item in RecyclerView cause view overlap like this video Link

fragment_feed.xml

fragment_feed.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none" />

在适配器中

holder.setIsRecyclable(false);
  ((PostViewHolder) holder).mUsername.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                deleteItem(holder.getAdapterPosition());
            }
        });

void deleteItem(int index) {
    postList.remove(index);
    notifyItemRemoved(index);

}

当我将notifyItemRemoved(index);更改为notifyDataSetChanged();时，似乎可以解决我的问题，但这是导致删除动画被破坏的原因. 我试图找到解决方案来解决此问题，但似乎没有人遇到同样的问题.感谢您的回答

When i change notifyItemRemoved(index); to notifyDataSetChanged(); seem to solved my problem but it's cause remove animation destroyed. I try to find solution to solve this but It's seem like no one have the same problem with me. Thanks for answer

@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {
    holder.setIsRecyclable(false);
    if (holder instanceof PostViewHolder) {
        Post post = (Post) postList.get(position);
        String type = post.getTypePost();

        // Inflate Layout //
        LayoutInflater inflater = LayoutInflater.from(mContext);


        ((PostViewHolder) holder).mUsername.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                deleteItem(holder.getAdapterPosition());
            }
        });

        ((PostViewHolder) holder).mUsername.setText(post.getOwnerPost());


    } else if (holder instanceof HeaderViewHolder) {

    } else{
        ((ProgressViewHolder) holder).progressBar.setIndeterminate(true);
    }
}

推荐答案

在onBindViewHolder中添加clickListener并按如下所示更改代码

Add the clickListener in onBindViewHolder and change the code like following

PostViewHolder postViewHolder=(PostViewHolder) holder;
postViewHolder.mUsername.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View view) {
            deleteItem(holder.getAdapterPosition());
        }
    });

void deleteItem(int index) {
    postList.remove(index);
    notifyItemRemoved(index);
    notifyItemRangeChanged(position, yourDataSet.size());
}
holder.setIsRecyclable(true);

在删除时，总是从数据列表中删除项目，然后通知适配器. 当每个观看者数据具有不同的数据状态时，也请使用holder.setIsRecyclable(false).

While deleting always remove item from datalist and then notifyAdapter. Also use holder.setIsRecyclable(false) when each viewholder data has different data state.
