what you need is action mode, in activity:

    @Override
    public void onActionModeStarted(ActionMode mode) {
        Menu menu = mode.getMenu();

        // you can remove original menu: copy, cut, select all, share ... or not
        menu.clear();

        // here i will get text selection by user
        menu.add(R.string.action_menu_preview_card)
                .setEnabled(true)
                .setVisible(true)
                .setOnMenuItemClickListener(item -> {
                    if (mWebview != null) {
                        mWebview.evaluateJavascript("window.getSelection().toString()", value -> {
                            value = StringUtil.trimToNull(value);
                            if (value != null) {
                                // do something about user select
                            }
                        });
                    }
                    // Post a delayed runnable to avoid a race condition
                    // between evaluateScript() result and mode.finish()
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mode.finish();
                        }
                    }, 200);
                    return true;
                });
        super.onActionModeStarted(mode);
    }

i has test it above android 21, this can handle action mode menu click, and mode.getMenuInflater().inflate(...) can't do it.
