i'm trying implement d-pad navigation in app. added android:focusable="true" recyclerview item, , android:descendantfocusability="afterdescendants" recyclerview. can navigate through items d-pad , down buttons, when press on center button, nothing happens. how can launch onitemclick method when center button pressed?

recyclerview item layout:

i tried add android:onclick="onitemclick" recyclerview item, doesn't work, because recyclerview works custom itemtouchlistener

    class recycleritemclicklistener extends recyclerview.simpleonitemtouchlistener {     private static final string tag = "recycleritemclicklisten";      // need define interface can use call on     interface onrecyclerclicklistener {         void onitemclick(view view, int position);          void onitemlongclick(view view, int position);     }      private final onrecyclerclicklistener mlistener;     private final gesturedetectorcompat mgesturedetector;      public recycleritemclicklistener(context context, final recyclerview recyclerview, onrecyclerclicklistener listener) {         // need context gesturedetector work         //need reference recyclerview we're detecting taps on         mlistener = listener;         mgesturedetector = new gesturedetectorcompat(context, new gesturedetector.simpleongesturelistener() {              @override             public boolean ondown(motionevent event) {                 // triggers first both single tap , long press                 return true;             }              @override             public void onlongpress(motionevent e) {                 log.d(tag, "onlongpress: starts");                 view childview = recyclerview.findchildviewunder(e.getx(), e.gety());                 if (childview != null && mlistener != null) { //                    log.d(tag, "onlongpress: calling listener .omitemlongclick");                     mlistener.onitemlongclick(childview, recyclerview.getchildadapterposition(childview));                 }             }              @override             public boolean onsingletapup(motionevent e) {                 log.d(tag, "onsingletapup: starts");                 view childview = recyclerview.findchildviewunder(e.getx(), e.gety()); // check see view underneath using coordinates on screen tapped                 // , return view found                 if (childview != null && mlistener != null) { //                    log.d(tag, "onsingletapup: calling listener .onitemclick");                     mlistener.onitemclick(childview, recyclerview.getchildadapterposition(childview)); // calls onitemclick mainactivity                 }                 // return true                 return true;             }         });      }      @override     public boolean onintercepttouchevent(recyclerview rv, motionevent e) {         //method called whenever sort of touch happens (tap, doubletap, swipe etc.)          if (mgesturedetector != null) {             boolean result = mgesturedetector.ontouchevent(e);             return result;         } else {              return false;         }     } } 

so tried add setonkeylistener recyclerview in answer - https://stackoverflow.com/a/32921945/7478869 doesn't change anything.
