invalidateOptionMenu() disables the clicking functionality of toolbar menu

问题

In my eCommerce app, I am using cart basket with count textview. Here for updates the cart count textview I used invalidateOptionMenu(); after that the clicking of cart navigates next fragment is not working. Even I tried in many ways,but did not worked.Please help me

This is my code:

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);


        badgeLayout = (RelativeLayout) menu.findItem(R.id.badge).getActionView();           /*-------Cart Basket with Counter---------*/
        basketCount = (TextView) badgeLayout.findViewById(R.id.counter);
        CommonUtil.dbUtil.open();
        try {
            MainActivity.basketCount.setText(String.valueOf(CommonUtil.dbUtil.getCartItem().getCount()));
        } catch (Exception e) {
            MainActivity.basketCount.setText(String.valueOf("0"));
        }

        badgeLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Toast.makeText(context, "Cart Clicked", Toast.LENGTH_SHORT).show();
                /*
                * menuItemClicked represents ToolBar OverFlow (...) menu is clicked.
                * */
                Config.menuItemClicked = true;
                SharedPreferences.Editor editor = CommonUtil.pref.edit();
                editor.putBoolean("cart_Clicked", Config.menuItemClicked);
                editor.apply();

                Intent next = new Intent(context, ProductActivity.class);
                startActivity(next);

            }
        });

        invalidateOptionsMenu();
        return super.onCreateOptionsMenu(menu);
    }

回答1:

instead of calling invalidateOptionMenu() inside your onCreateOptionsMenu() you should call it when you are updating the count value that you set in basketCount TextView.

Calling invalidateOptionsMenu() is of no avail there, so when you add item to your cart at that you should call invalidateOptionsMenu().
