Combine use of OnClickListener and OnLong Click Listener

Question

Actually I created a pdf viewer and i jus want to create a longclicklistener to open my new activity and as u can see here Screenshot And there is already a click listener assigned with this button and i also want to combine longclicklistener so when i long click that button then automatically launch my second activity

public void actionButtonClick(View view) {
        if (pageCount == 0) {
            Toast.makeText(getApplicationContext(), getString(R.string.no_selected_pdf), Toast.LENGTH_LONG).show();
            return;
        }
        final BottomSheetDialog dialog = new BottomSheetDialog(MainActivity.this);
        dialog.setContentView(R.layout.bottom_sheet);
        dialog.setCanceledOnTouchOutside(true);
        NumberPicker numberPicker = (NumberPicker) dialog.findViewById(R.id.number_picker);
        if (numberPicker != null) {
            numberPicker.setMaxValue(pageCount);
            numberPicker.setValue(pdfView.getCurrentPage() + 1);
            numberPicker.setOnValueChangedListener((picker, oldVal, newVal) -> {
                pdfView.jumpTo(newVal - 1, true);
            });
        }
        dialog.show();
    }


    public void openButtonClick(View view) {
        launchPicker();
    }

    private void startAnimation(int state) {
        actionLayout.animate()
                .translationY(state == 0 ? actionLayout.getHeight() : 0)
                .alpha(state == 0 ? 0 : 1.0f)
                .setDuration(300).setListener(new AnimatorListenerAdapter() {
                    @Override
                    public void onAnimationEnd(Animator animation) {
                        menu.findItem(R.id.hide_or_show_button).setChecked(state != 1);
                        super.onAnimationEnd(animation);
                    }
                });
    }

    private void hideOrShowActionButton() {
        if (actionLayout.getAlpha() == 1.0)
            startAnimation(0);
        else
            startAnimation(1);
    }

    private void showSnackBar(@NonNull String msg, boolean isError) {
        Snackbar snackbar = Snackbar
                .make(findViewById(R.id.main_layout), msg, Snackbar.LENGTH_SHORT);
        snackbar.setBackgroundTint(ContextCompat
                .getColor(Objects.requireNonNull(getApplicationContext()),
                        isError ? R.color.err_color : R.color.main_color));
        snackbar.setTextColor(ContextCompat
                .getColor(Objects.requireNonNull(getApplicationContext()), R.color.white));
        snackbar.show();
    }

    @Override
    public void loadComplete(int nbPages) {
        pageCount = nbPages;
        warningLayout.setVisibility(View.GONE);
        PdfDocument.Meta meta = pdfView.getDocumentMeta();
        detailsMap.clear();
        detailsMap.add(meta.getTitle());
        detailsMap.add(meta.getAuthor());
        detailsMap.add(meta.getSubject());
        detailsMap.add(meta.getKeywords());
        detailsMap.add(meta.getCreator());
        detailsMap.add(meta.getProducer());
        detailsMap.add(dateFormatter(meta.getCreationDate()));
        detailsMap.add(dateFormatter(meta.getModDate()));
    }

    private String dateFormatter(String data) {
        if (!data.isEmpty()) {
            String date = data.substring(2);
            String y = date.substring(0, 4);
            String m = date.substring(4, 6);
            String d = date.substring(6, 8);
            return y + "/" + m + "/" + d;
        } else {
            return data;
        }
    }

    @Override

I suggest that you use an onTouchListener instead.

By using an onTouchListener, you could adjust the difference between a click and a long click.

long start;
myButton.setOnTouchListener(new View.OnTouchListener(){
  @Override
  public boolean onTouch(final View v, final MotionEvent event){
    switch(event.getAction()){
      case MotionEvent.ACTION_DOWN:
        start=System.currentTimeMillis();
        return true;
      case MotionEvent.ACTION_UP:
        if(System.currentTimeMillis()-start<500){ //Click is less than 500ms, you can adjust this value later...
          //Do what you want on click over here...
        }else{
          //It's a long click, do what you want over here...
        }
        return true;
      default:
        return false;
    }
});
