XML : recyclerview : how to disable focusability( clickable buttons) during Animation

my problem is the following : i have 2 animators xml files into android project :

bouceDown :

  <?xml version="1.0" encoding="utf-8"?>  <set xmlns:android="http://schemas.android.com/apk/res/android"      android:interpolator="@android:anim/bounce_interpolator">      <translate          android:fromYDelta="-100%p"          android:toYDelta="0"          android:duration="2500"/>  </set>    

and bouceUp

  <?xml version="1.0" encoding="utf-8"?>  <set xmlns:android="http://schemas.android.com/apk/res/android"      android:interpolator="@android:anim/bounce_interpolator">      <translate          android:fromYDelta="0"          android:toYDelta="-100%p"          android:duration="2500"/>  </set>    

they are triggering visibility of Recyclerview letters(a-z) with a nice boucing effect

i added them as following in my Java class :

  public class FragmentResults extends Fragment implements Animation.AnimationListener {            private Animation scrollUp, scrollDown;      private boolean isAlreadyVisible = false;        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {            final View v = inflater.inflate(R.layout.fragment_results, container, false);           ....            buttonLetters.setOnClickListener(new View.OnClickListener() {              @Override              public void onClick(View v) {                    toggleRecycler(false);                  isAlreadyVisible = true;                  for (int i = 0; i < letters.size(); i++) {                      if (letters.get(i).getLetter().equals(buttonLetters.getText())) {                          ((MyGridlayout) recyclerViewLetters.getLayoutManager()).scrollToPositionWithOffset(i, 0);                          break;                      }                  }              }          });            .....          return v;      }          @Override      public void onViewCreated(View view, Bundle savedInstanceState) {          super.onViewCreated(view, savedInstanceState);          ....          scrollDown.setAnimationListener(this);          scrollUp.setAnimationListener(this);          ....        }            private void toogleButtonLetterVisibility(View v) {          if (entities.size() < 20) return;          if (buttonLetters.getVisibility() == View.GONE) {                buttonLetters.setVisibility(View.VISIBLE);                v.postDelayed(new Runnable() {                  @Override                  public void run() {                      buttonLetters.setVisibility(View.GONE);                    }              }, 4000);          }      }        public void toggleRecycler(boolean isVisible) {          if (isVisible) {              if (isAlreadyVisible)                  recyclerViewLetters.startAnimation(scrollUp);//here i start animation scrollup              isAlreadyVisible = false;            } else {              buttonLetters.setVisibility(View.GONE);              recyclerViewLetters.startAnimation(scrollDown);//here i start animation scrolldown          }        }        @Override      public void onAnimationStart(Animation animation) {          recyclerViewLetters.setFocusable(false);//here i try to remove recyclerview focusability          if (isAlreadyVisible) {              recyclerViewLetters.setVisibility(View.VISIBLE);              Log.d("viewVisibility", "visible");          }      }        @Override      public void onAnimationEnd(Animation animation) {          if (!isAlreadyVisible) {              recyclerViewLetters.setVisibility(View.GONE);          }          recyclerViewLetters.clearAnimation();          recyclerViewLetters.setFocusable(true);//here i try to make recyclerview focusable again        }        @Override      public void onAnimationRepeat(Animation animation) {        }  }    

i wonder why this part isn't working :

  @Override      public void onAnimationStart(Animation animation) {          recyclerViewLetters.setFocusable(false);//here i try to remove recyclerview focusability          if (isAlreadyVisible) {              recyclerViewLetters.setVisibility(View.VISIBLE);              Log.d("viewVisibility", "visible");          }      }        @Override      public void onAnimationEnd(Animation animation) {          if (!isAlreadyVisible) {              recyclerViewLetters.setVisibility(View.GONE);          }          recyclerViewLetters.clearAnimation();          recyclerViewLetters.setFocusable(true);//here i try to make recyclerview focusable again        }        @Override      public void onAnimationRepeat(Animation animation) {        }    

i tried also with setclickable(false/true) but it doesn't work, im still able to click my letters during animation effect, did someone encouter the same problem and find any solution?
