recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));

recyclerView.setAdapter(adapter);

如果你想使用水平回收器视图作为ViewPager，那么现在可以使用线性snaphelper的帮助，它是在支持库24.2.0版本中添加的。

首先添加RecyclerView到你的活动/片段

<android.support.v7.widget.RecyclerView
    android:layout_below="@+id/sign_in_button"
    android:layout_width="match_parent"
    android:orientation="horizontal"
    android:id="@+id/blog_list"
    android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>

在我的情况下，我已经使用了一个CardView在RecyclerView

blog_row.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView

    xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_margin="15dp"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:orientation="vertical">

            <com.android.volley.toolbox.NetworkImageView
                android:id="@+id/imageBlogPost"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:adjustViewBounds="true"
                android:paddingBottom="15dp"
                android:src="@drawable/common_google_signin_btn_text_light_normal" />

            <TextView
                android:id="@+id/TitleTextView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
               android:layout_marginBottom="20dp"

                android:text="Post Title Here"
                android:textSize="16sp" />

            <TextView
                android:id="@+id/descriptionTextView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Post Description Here"
                android:paddingBottom="15dp"
                android:textSize="14sp" />
        </LinearLayout>

    </android.support.v7.widget.CardView>

在你的活动/片段中

private RecyclerView mBlogList;

LinearLayoutManager layoutManager =
    new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);

mBlogList = (RecyclerView) findViewById(R.id.blog_list);
mBlogList.setHasFixedSize(true);
mBlogList.setLayoutManager(layoutManager);

LinearSnapHelper snapHelper = new LinearSnapHelper() {
    @Override
    public int findTargetSnapPosition(RecyclerView.LayoutManager lm, int velocityX, int velocityY) {
        View centerView = findSnapView(lm);
        if (centerView == null)
            return RecyclerView.NO_POSITION;

        int position = lm.getPosition(centerView);
        int targetPosition = -1;
        if (lm.canScrollHorizontally()) {
            if (velocityX < 0) {
                targetPosition = position - 1;
            } else {
                targetPosition = position + 1;
            }
        }

        if (lm.canScrollVertically()) {
            if (velocityY < 0) {
                targetPosition = position - 1;
            } else {
                targetPosition = position + 1;
            }
        }

        final int firstItem = 0;
        final int lastItem = lm.getItemCount() - 1;
        targetPosition = Math.min(lastItem, Math.max(targetPosition, firstItem));
        return targetPosition;
    }
};

snapHelper.attachToRecyclerView(mBlogList);

最后一步是将适配器设置为RecyclerView

mBlogList.setAdapter(firebaseRecyclerAdapter);

水平方向和垂直方向都适用。

RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_recycler);
    recyclerView = (RecyclerView)findViewById(R.id.recyclerViewId);

    RecyclAdapter adapter = new RecyclAdapter();

    //Vertical RecyclerView
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerView.setLayoutManager(mLayoutManager);

    //Horizontal RecyclerView
    //recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL,false));

    recyclerView.setAdapter(adapter);

}

试图构建一个水平的ListView花费了太多的时间。我用两种方法解决了这个问题。

通过使用一个ViewPager，它的适配器扩展自PagerAdapter。 通过像上面一样使用RecyclerView。我们需要像下面的代码一样应用LayoutManager: LinearLayoutManager layoutManager = new LinearLayoutManager(这个，LinearLayoutManager。水平,假); RecyclerView myList = (RecyclerView) findViewById(R.id.my_recycler_view); myList.setLayoutManager (layoutManager);

有一个名为HorizontalGridView的RecyclerView子类。你可以用它来表示水平方向。 垂直方向的VerticalGridView。

 <android.support.v7.widget.RecyclerView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layoutManager="android.support.v7.widget.LinearLayoutManager" />
