Showcaseview library calling multiple times on Recyclerview's first item

Question

I am using https://github.com/florent37/TutoShowcase this showcaseview library in my code.

It works fine in activity and fragment.But when I call in recyclerview item it shows multiple popups and gets blackout.

mRecyclerViewList.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    Logger.log("Call");

                    TextView textView = (TextView) mRecyclerViewList.getChildAt(0).findViewById(R.id.txt_add_tocart_btn);
                    Logger.log("Textview" + textView);
                    textView.setFocusableInTouchMode(true);
                    TutoShowcase.from((Activity) context).setContentView(R.layout.tuto_showcase_tuto_sample)
                            .setFitsSystemWindows(true).on(textView).addRoundRect(35).showOnce("1").show();
                    // unregister listener (this is important)
                    if (Build.VERSION.SDK_INT < 16) {
                        mRecyclerViewList.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                    } else {
                        mRecyclerViewList.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    }
                }
            });

How can I avoid multiple popup's?

Answer 1

Your question how to avoid Multiple popup's:

Just set a boolean value to avoid showing multiple times.

boolean isShown = false;

mRecyclerViewList.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    Logger.log("Call");
                    if(!isShown){
                      TextView textView = (TextView) mRecyclerViewList.getChildAt(0).findViewById(R.id.txt_add_tocart_btn);
                      Logger.log("Textview" + textView);
                      textView.setFocusableInTouchMode(true);
                      TutoShowcase.from((Activity) context).setContentView(R.layout.tuto_showcase_tuto_sample)
                            .setFitsSystemWindows(true).on(textView).addRoundRect(35).showOnce("1").show();
                       isShown = true;
                     }
                    // unregister listener (this is important)
                    if (Build.VERSION.SDK_INT < 16) {
                        mRecyclerViewList.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                    } else {
                        mRecyclerViewList.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    }
                }
            });
