In Android, I am showing images using RecyclerView:

How to show exactly 3 items in the visible area of RecyclerView? How to avoid to show "half" items? Is this possible?

RecyclerView:

        <android.support.v7.widget.RecyclerView
            android:layout_width="wrap_content"
            android:layout_height="130dp"
            android:id="@+id/rvProducts" />

One item in recycler view:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:id="@+id/ivProduct"
        android:src="@drawable/noimage"/>

</LinearLayout>

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);

One solution is to set width of each child programmatically like.

view.getLayoutParams().width = getScreenWidth() / VIEWS_COUNT_TO_DISPLAY;

And the screen size like this:

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics).widthPixels;
