The Next.js documentation states, that the directory src/pages is an alternative to /pages. However, my custom _app.tsx and _document.tsx files, get ignored when the pages folder is moved into src.

You can recreate this issue yourself, when creating an empty Next.js App, moving the pages folder into src and updating the import paths of the css files. The content of the index.tsx file will still be rendered, but modifications to the styles/globals.css, which is imported in the _app.tsx …

我希望在这里找到一些帮助,因为我不熟悉Android中的BroadcastReceivers.这段代码打开WebView会将您重定向到登录页面,并在检测到URL更改后接收登录令牌.之后,活动将关闭.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    mLoginWebView = (WebView) findViewById(R.id.webview_login);

    redirectUrl = getString(R.string.app_redirect_url);


    //RECEIVE PLATFORM ID
    Bundle bundle = getIntent().getExtras();
    if(bundle != null){
        platform = bundle.getInt(ConstantsHelper.LOGIN_EXTRA_TOKEN);
    }

    mLoginWebView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            Log.d(TAG, "URL change to to " + url + " was detected");

            if (url.contains(redirectUrl) || url.contains("passport.twitch.tv")) {

                Log.d(TAG, "Login with platform " + platform);

                switch (platform){

                    //GET INSTAGRAM AUTH TOKEN
                    case ConstantsHelper.ID_INSTAGRAM:{
                        String accessToken = url.split("=")[1];

                        SharedPreferenceHelper.putString(ConstantsHelper.PREF_INST_ACCESS_TOKEN, accessToken);
                        NetworkManager.getInstance().catchTokens(); …

大家好!

我在最近建立的主页上遇到了一些问题.我尝试使用"内容"类淡入HTML div,并将两条日志消息都放入控制台,但它仍然没有消失!

当然,我删除了这些代码段中的所有不需要的信息

这是我的HTML

<div class="content">  </div>

还有我的CSS

.content{
margin: 0px;
position: fixed;
display:none
background-image: url("../img/city_topdown_blurred.png");
background-size:cover;
width: 100%;
height: 100%;
}

最后是我的jquery

$(document).ready(function(){
  console.log("fading in");
  $('.content').fadeIn("slow", function(){
    console.log("fading done");
  });
});

即使时间设置为10000或更高,这两条日志消息也会立即推送到我的浏览器(Chrome).

如果HashMap为空,我检查.containsKey() 我得到一个空答案.

我的问题是,如果我想检查null,我会收到一条错误消息

if(containsKey == null || !containsKey){

我收到错误消息

Operator '==' cannot be applied to 'boolean', 'null'

有人能告诉我为什么会这样.我认为这应该有效
