RecyclerView适配器位置更改视图大小和可见性时出现问题

我创建了一个标准的回收器视图适配器,但它有一个奇怪的问题,某些视图将随机更改其可见性或大小,

好的,我随机地说,很明显是我改变了这些视图的大小和/或可见性,所以让我们举一个简单的例子,如果我改变了位置0的可见性,使其消失,因为我的对象没有文本在里面,当适配器被称为位置0时,确实会消失,但是如果我向下滚动,视图变为可见,就会发生类似的事情在我的文本视图中,如果少于10个字符,应该是x大小,否则应该是y大小,第一次加载时大小是正确的,但是向下滚动和向后滚动大小会改变,我知道在幕后视图是加载和回收的(因此命名为回收视图),但是我认为传入onbindViewHolder(final myViewHolder holder,final int position)的位置总是正确的,因为它来自主列表,如果有人能在这里帮我,我会很感激,因为现在我在挠头,我在因为担心没有包含足够的适配器类,所以要发布我的整个适配器类,但通常我认为它的onBindViewHolder是主要的罪魁祸首,它包含了很多主要的任意代码,如前所述,一切工作到一定程度,但我有奇怪的错误,当上下滚动时,随着视图的变化,我相信我正在做的一切我应该是一切显示正确的数据只是不总是正确的大小或可见性,将感谢任何帮助
