Oct 16, 2020 · 这可以看到,控制图片状态的地方就是一个recyclerview. 思路. 利用recyclerview的多行视图来实现! 微信上的效果是,先选中图片后才会进入这个界面,这里实现的是我现在项目中用到的效果:默认显示一个带+好的图片,点击这个图片,会让你选择图片。. In your getItemViewType(int position) method of adapter, assign unique values for each video, so it will always return same ViewHolder for same video as you wish.. return unique positive number as type for each video type (here i used the adapter position as unique key); return negative numbers for any non-video items. (nothing special here, just to avoid conflicts with video items,. 5.如果是onBindViewHolder没有被调用,尝试是不是没重写getItemViewType导致。 @Override public int getItemViewType(int position) { return position; } 再没被调用可以尝试 调整 RecyclerView 的复用逻辑和方式来解决 onBindViewHolder 没有调用的这个问题。. recyclerview中的多标题android 现在我的要求就像我上传图片或视频一样,上传状态应显示在服务器显示的数据的顶部。 i-e位于recyclerview的第0位。 我可以添加任意数量的图像或视频。 图片或视频成功上传后,我也想从recyclerview中删除该行。 我想过使用getItemViewType()。 在这个使用两个布局。 我不知道这种方法是否正确。 我没有得到任何解决这个, 请..... 任何帮助...... 来源 2016-03-06 Mohd Asif Ahmed. Make sure you implement the RecyclerView.Adapter exactly like above, otherwise the multiple view will not work. Now the getItemViewType override method that chooses your viewTypes will look like this: override fun getItemViewType (position: Int) = items [position].identifier (). By using getItemViewType (), the RecyclerView is working with you to recycle the exact view you need. You can even have two FeedItem subclasses, one for module_yes_no and one for module_custom, so in onBindViewHolder (), you just check the class of the ViewHolder and branch accordingly. That should help improve the performance of your app.

The Adapter class for the RecyclerView contains three major methods that need to be overridden. getItemViewType () onCreateViewHolder () onBindViewHolder () We'll be using switch statements in the getItemViewType () method to return the respective viewType. This viewType variable is internal to the Adapter class.
