Android Recyclerview to implement the horizontal sliding code _android

Recyclerview is a newly added SDK in the Android L version to replace ListView, which is more flexible and fungible than ListView. This article introduces the Android Recyclerview to achieve the horizontal sliding code, together to see.

Android.support.v7.widget.RecyclerView

function: recyclerview Transverse slide

Control: <android.support.v7.widget.recyclerview/>

Java classes: Recyclerview, Galleryadapter, list<integer>

1, the main interface layout

<?xml version= "1.0" encoding= "Utf-8"?> <relativelayout xmlns: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> 

2. Sub-interface layout

<?xml version= "1.0" encoding= "Utf-8"?> <relativelayout xmlns: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= " Some info " 
android:textsize=" 12DP "/>
