Android中RecyclerView实现横向滑动代码
RecyclerView是AndroidL版本中新添加的一个用来取代ListView的SDK,它的灵活性与可替代性比listview更好。本文给大家介绍Android中RecyclerView实现横向滑动代码，一起看看吧。
android.support.v7.widget.RecyclerView
功能：RecyclerView横向滑动
控件：<android.support.v7.widget.RecyclerView/>
Java类：RecyclerView、GalleryAdapter、List<Integer>
1、主界面布局
<?xmlversion="1.0"encoding="utf-8"?> <RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.info.activity.RecyclerActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/id_recyclerview_horizontal" android:layout_width="match_parent" android:layout_height="120dp" android:layout_centerVertical="true" android:background="#FF0000" android:scrollbars="none" ></android.support.v7.widget.RecyclerView> </RelativeLayout>
2、子界面布局
<?xmlversion="1.0"encoding="utf-8"?> <RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="120dp" android:layout_height="120dp"> <ImageView android:id="@+id/id_index_gallery_item_image" android:layout_width="80dp" android:layout_height="80dp" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_margin="5dp" android:scaleType="centerCrop"/> <TextView android:id="@+id/id_index_gallery_item_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/id_index_gallery_item_image" android:layout_centerHorizontal="true" android:layout_marginBottom="5dp" android:layout_marginTop="5dp" android:textColor="#000000" android:text="someinfo" android:textSize="12dp"/> </RelativeLayout>
