我的on背态似乎正在反向工作

Question

我已经为这个问题苦苦挣扎了大约一天。当我按下手机上的后退按钮时，它会向后运行我的代码。谁能告诉我为什么会发生这种情况以及我将如何解决它？

public void onBackPressed() {
    displayToast("Pressed Back"); // Executed last
    superWebView.evaluateJavascript("window.sessionStorage.getItem('windowActive')",
            new ValueCallback<String>()  {
                @Override
                public void onReceiveValue(String value)
                {
                    if ("logo.html".equals(value)) { // Gets skipped
                        displayToast("Press back again to exit");
                        new AlertDialog.Builder(mAppContext)
                                .setTitle("Closing Program")
                                .setMessage("Are you sure you want to exit Vertex?")
                                .setPositiveButton("Yes", (dialog, which) -> finish())
                                .setNegativeButton("No", null)
                                .show();
                    } else {
                        displayToast("Default"); // This executes first
                        superWebView.loadUrl("javascript:goBack()");
                    }
                }
            });
