title: How to show exact number of items in RecyclerView?
body: <p>I am trying to show exact (eg. 3 items) in RecyclerView. Our web application shows like this:</p>
  
  <p><a href="https://i.stack.imgur.com/Avxaf.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Avxaf.png" alt="enter image description here"></a></p>
  
  <p>If I move items:</p>
  
  <p><a href="https://i.stack.imgur.com/bOGhV.png" rel="noreferrer"><img src="https://i.stack.imgur.com/bOGhV.png" alt="enter image description here"></a></p>
  
  <p>and release the mouse, it automatically comes to this:
  <a href="https://i.stack.imgur.com/5t2PZ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/5t2PZ.png" alt="enter image description here"></a></p>
  
  <p>In Android, I am showing images using RecyclerView:</p>

  <p><strong>How to show exactly 3 items in the visible area of RecyclerView? How to avoid to show "half" items? Is this possible?</strong></p>
  
  <p>RecyclerView:</p>
  
  <pre><code>        &lt;android.support.v7.widget.RecyclerView
              android:layout_width="wrap_content"
              android:layout_height="130dp"
              android:id="@+id/rvProducts" /&gt;
  </code></pre>
  
  <p>One item in recycler view:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical" android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;ImageView
          android:layout_width="100dp"
          android:layout_height="wrap_content"
          android:padding="10dp"
          android:id="@+id/ivProduct"
          android:src="@drawable/noimage"/&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>    LinearLayoutManager layoutManager
              = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
      RecyclerView productImageList = (RecyclerView) view.findViewById(R.id.rvProducts);
      productImageList.setLayoutManager(layoutManager);
      GalleryRecyclerAdapter adapter = new GalleryRecyclerAdapter(images);
      productImageList.setAdapter(adapter);
  </code></pre>
