如何在recyclelerview滚动时隐藏/显示布局(如twitter的新推文布局)

问题描述 投票:3回答:2

我想添加一个在recyclelerview滚动时隐藏/显示的布局。当recyclerview向下滚动时,该布局将隐藏,将在recyclelerview向上滚动时显示,例如twitter的新推文布局。我可以为appbarlayout做这件事,但我不能为那个布局做。我怎样才能做到这一点?

紫色布局会像动作栏一样隐藏显示:

这是我的布局文件:

<android.support.v4.widget.DrawerLayout

android:id="@+id/drawerLayout"

android:layout_height="match_parent"
android:elevation="7dp">

我有一个简单的解决方案..

 recyclerview.addOnScrollListener(new HidingScrollListener()
    {

        @Override
        public void onHide()
        {

            tabss.animate().translationY(tabss.getHeight())
                    .setInterpolator(new AccelerateInterpolator(2)).start();      
           filtershow.animate().translationY(-filtershow.getHeight())
                  .setInterpolator(new AccelerateInterpolator(1));
        }

        @Override
        public void onShow()
        {
            tabss.animate().translationY(0).setInterpolator(new
                    DecelerateInterpolator(2)).start();
         filtershow.animate().translationY(0).setInterpolator
                 (new DecelerateInterpolator(1)).start();
        }
    });

在Recyclerview中我隐藏了屏幕顶部过滤器和屏幕底部标签如果你想对这个隐藏布局有疑问,请问我。我将提供您所需的代码。
