如何从Recycler视图隐藏一个项目在特定的条件？ [英] How to hide an item from Recycler View on a particular condition?

问题描述

我正在使用Firebase Recycler Adapter（Firebase UI Library）来填充Recycler View。我想在一个条件上隐藏一个项目（行）。
我有一个包含回收视图的LinearLayout。

我将线性布局可见性设置为 populateViewHolder（）

  @Override 
 protected void populateViewHolder（UsersViewHolder viewHolder，User user，int position ）{
 
 if（user.getUserEmail（）。equals（Utils.decodeEmail（userEmail）））{
 viewHolder.llMain.setVisibility（View.GONE）; 
 return; 
} 
 
 viewHolder.tvUserEmail.setText（user.getUserEmail（））; 
 
 
 
 
 
 $ p 
它隐藏了LinearLayout，但行保持空白。
 
 
 
是否有任何方法我应该重写以克服这个问题或者是否有任何方法来实现结果？ 
 
解决方案
 
 $ b 
  view.setVisibility（View.GONE）; 
 / code> 
 
I am using Firebase Recycler Adapter (Firebase UI Library) to populate Recycler View. I want to hide an item(row) on a condition. 
I have a LinearLayout containing a recycler view.

I set linear layout visibility to Gone in populateViewHolder() method of recycler view adapter.
@Override
protected void populateViewHolder(UsersViewHolder viewHolder, User user, int position) {

    if (user.getUserEmail().equals(Utils.decodeEmail(userEmail))) {
        viewHolder.llMain.setVisibility(View.GONE);
        return;
    }

    viewHolder.tvUserEmail.setText(user.getUserEmail());
}
It hides the LinearLayout but the row remains there with empty space.

Is there any method I should override to overcome this or is there any way to achieve the result?
解决方案
You should hide all views or parent from UsersViewholder layout xml.

view.setVisibility(View.GONE);
