The use of the Android 5.0 V7 Expansion Pack Recyclerview and the encapsulation implementation of the Universal adapter

Add Gradle Dependency

' com.android.support:appcompat-v7:23.2.1 '
' com.android.support:recyclerview-v7:23.2.1 '

Note: The version number of Recyclerview is consistent with AppCompat, here: v7:23.2.1 defines generic recyclerviewhold objects in a generic manner, and internally sparsearray the view object to improve the parsing speed of the XML.

/**
* Created by Administrator on 2016/6/14.
* General Recycler.viewholder
 */
Public classUnityrecycleradapterviewholderextendsRecyclerview.viewholder {
    private static FinalUtilslogLG= Utilslog.GetLogger(Unityrecycleradapterviewholder.class);
PrivateSparsearray<view>mviews;
PrivateViewMconvertview;

 PublicUnityrecycleradapterviewholder (View Itemview, ViewGroup parent) {
        Super(Itemview);
 This.Mconvertview= Itemview;
 This.mviews=NewSparsearray<> ();
}

     PublicViewGetconvertitemview() {
        returnMconvertview;
}

    /**
* Get control by Viewid
     *
     * @paramviewId
* @return
*/
 Public<TextendsView>TGenerateview(intVIEWID) {
View view =mviews. Get (ViewId);
if(View = =NULL) {
View =Mconvertview. Findviewbyid (ViewId);
mviews. put (ViewId, View;
}
        return(T) View;
}

     Public<TextendsView>TGenerateview(intViewId, class<T> Clz) {
        return(T) Generateview (VIEWID);
}
}

rewrite Oncreateviewholder with Onbindviewholder, whereOncreateviewholder generates a View object for each item and wraps it back into the Viewholder;Onbindviewholder is responsible for rendering the data to view

/**

* 1.getItemLayoutId and Getitemlayoutview Choose one of the two to make a carbon copy: Support layout and code mode here
* 2. The class can also continue to expand, for cases where there is only a single layout, you can inject itemlayoutid directly through the construction method

Public voidConvert(Corepageentity itementity, Unityrecycleradapterviewholder Viewholder, intPosition) {
        if(Position! =0) {
            LG. E ("Convert with position"+ Position +":" + viewholder.tostring ());
}
Viewholder.generateview (r.id.Imgitemcommon, ImageView.class). Setvisibility (View.GONE);
Viewholder.generateview (r.id.Tvitemcommon, TextView.class). SetText (Itementity.getcorepagetitle ());
}
};

Gridactmain. Setadapter (Adapter);
Gridactmain. Setlayoutmanager (NewGridlayoutmanager (Getcuractivity (), 1));

Adapter. Getdatamodifyhelper (). Setdataresource (//Add data Set);
