How to use Recyclerview and how to set up tap listening

Recyclerview is derived from the ListView, which is more efficient than the ListView and is more convenient to use.

This article explains how to do this with Recyclerview: vertical list effects, landscape list effects, grid list effects , waterfall flows (Landscape and portrait), and Item's Click to listen (because Recyclerview does not have the item's click to listen function, here is my self-created, the feeling is still useful). That's a powerful effect, isn't it? Haha, see the source code below

(1) Main layout

<?XML version="1.0"encoding="Utf-8"?>
<relativelayoutxmlns:Android="Http://schemas.android.com/apk/res/android"
Android: Layout_width="Match_parent"
Android: layout_height="Match_parent">

<android.support.v7.widget.recyclerview
Android: id="@+id/recyclerview"
Android: Layout_width="Match_parent"
Android: layout_height="Match_parent"/>

</RelativeLayout>

(2) Item

<?XML version="1.0"encoding="Utf-8"?>
<linearlayoutxmlns:Android="Http://schemas.android.com/apk/res/android"
Android: Layout_width="Match_parent"
Android: layout_height="Match_parent"
Android: orientation="Vertical">

<textview
Android: id="@+id/tv"
Android: textsize="60DP"
Android:p adding="20DP"
Android: Layout_width="Wrap_content"
Android: layout_height="Wrap_content"/>

</LinearLayout>

(3) Mainactivity code

Mainactivity appcompatactivity {Recyclerview string[] = {} (Bundle savedinstancestate) {. OnCreate (Savedinstanc eState) Setcontentview (r.layout.) = (Recyclerview) Findviewbyid (r.id.). Sethasfixedsize () Staggeredgridlayoutmanager Staggeredgridlayoutmanager =staggeredgridlayoutmanager ( Staggeredgridlayoutmanager.). Setlayoutmanager (Staggeredgridlayoutmanager). Setadapter (Myadapter ())

(4) Adapter Adapter

myadapter recyclerview.adapter<myadapter.viewholder>{    string[]  Myadapter (String[] mdatas) {        =mdatas}     ViewHolder  (Viewgroup parentviewtype)  {         View view=layoutinflater. (Parent.getcontext ()). Inflate (r.layout.parent) Viewholder viewholder=viewholder (Viewparent.getContext ()) viewholder}     (viewholder holderposition)  {         holder. SetText ([position])}     ()  {        .}     ViewHolder RecyclerView.ViewHolder View.OnClickListener {         textview context viewholder (view itemviewcontext  Context)  {             (Itemview) =&NBSP; (TextView)  itemview.findviewbyid (r.id.). =contextitemview.setonclicklistener ()}         (View v)  {             toast. (. GetText (). toString () Toast.). Show ()}    }}

Operating effect:
