There are many ideas and solutions to achieve. * The solution to this case is this: * 1th step: Write yourself a public interface Onrecyclerviewitemclicklistener, this interface is used for callback responses. The user's Click event. * 2nd step: Put Onrecyclerviewitemclicklistener new out, is actually complete the interface method inside: Onrecyclerviewitemclicklistener (). We will complete a ListView-like Onitemclicklistener () in the Onrecyclerviewitemclicklistener method body. * 3rd step, key point. Here, a solution that implements the Recyclerview click Response callback has multiple choices and paths, and this case chooses to add a click event to the parameter view in the Viewholder constructor: * Public MyViewHolder (View Itemview) {super (Itemview); Itemview.setonclicklistener (new View.onclicklistener () {@Override public void OnClick (View v) {_click (v);}}); Then we write an extra: _click (View v) and then call _click (v) to trigger the Onrecyclerviewitemclicklistener (Note: More parameters can be carried and passed in this process depending on the requirements): _click ( View v) {Monrecyclerviewitemclicklistener.onrecyclerviewitemclicklistener (this, V, POS); The ability to increase click Response time for Recyclerview is completed. * * * by Phil * * */public class Mainactivity extends Actionbaractivity {//Add Click event Interface part 1private ONRECYCLERVIEWITEMCL Icklistener Monrecyclerviewitemclicklistener = new Onrecyclerviewitemclicklistener () {//Specific click events in this @overridepublic void Onrecyclerviewitemclicklistener (Viewholder holder,view View, int pos) {toast.maketext (Getapplication (), pos + "", Toast.length_short).
