Android 是否应在自定义Cordova CordovaWebViewClient上重写URL加载不再工作
我有一个自定义类来重写CordovaWebViewClient提供的shouldOverrideUrlLoading方法Android 是否应在自定义Cordova CordovaWebViewClient上重写URL加载不再工作,android,cordova,webview,Android,Cordova,Webview,我有一个自定义类来重写CordovaWebViewClient提供的shouldOverrideUrlLoading方法 public class CordovaCustomWebClient extends CordovaWebViewClient { public CordovaCustomWebClient(CordovaInterface cordova, CordovaWebView view) { super(cordova, vie
public class CordovaCustomWebClient extends CordovaWebViewClient {
public CordovaCustomWebClient(CordovaInterface cordova, CordovaWebView view) {
super(cordova, view);
}
@SuppressLint("DefaultLocale")
@SuppressWarnings("deprecation")
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
EventLogger.logMessage(getClass(), "--------------- shouldOverrideUrlLoading ---------------");
return super.shouldOverrideUrlLoading(view, url);
}
在我升级到Cordova的最新版本(3.6.3)之前,它一直运行良好。现在不再调用shouldOverrideUrlLoading函数,但是当我调试代码时,我可以看到同一个函数正在Cordova库(类CordovaWebViewClient)中执行
以下是我如何覆盖Cordova的web客户端:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_application);
cordovaWebView = (CordovaWebView) this.findViewById(R.id.mainView);
Config.init(this);
Application application = null;
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
application = (Application) bundle.get("key_application");
}
// Local Url to load application
String url = "";
if (application != null) {
if (HubManagerHelper.getInstance().getApplicationHosted() == null) {
MyApp app = (MyApp) getApplication();
app.registerDefaultHubApplication();
}
url = String.format(WebServicesClient.URL_WEB_APPLICATION, HubManagerHelper.getInstance()
.getApplicationHosted(), application.getPath());
}
cordovaWebView.setWebViewClient(new CordovaCustomWebClient(this, cordovaWebView));
// Listener to Download Web File with Native Component - Download Manager
cordovaWebView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype,
long contentLength) {
downloadAndOpenFile(WebApplicationActivity.this, url);
}
});
String ua = cordovaWebView.getSettings().getUserAgentString();
String appVersion = getAppVersion();
String newUA = ua.concat(" MyApp." + appVersion);
cordovaWebView.getSettings().setUserAgentString(newUA);
if (savedInstanceState == null) {
cordovaWebView.loadUrl(url);
} else {
((LinearLayout) findViewById(R.id.view_loading)).setVisibility(View.GONE);
}
今天升级到3.6.3后,我遇到了完全相同的问题。需要查看Cordova的源代码才能弄清楚为什么会出现这种情况。在某个时候,引入了一个新方法,
init
,它从config.xml读取一组参数。如果您的代码未调用该方法,则加载url时,它将命中initifneeded
案例,这反过来将覆盖已设置的任何自定义客户端
根据他们的代码:
private void initIfNecessary() {
if (pluginManager == null) {
Log.w(TAG, "CordovaWebView.init() was not called. This will soon be required.");
// Before the refactor to a two-phase init, the Context needed to implement CordovaInterface.
CordovaInterface cdv = (CordovaInterface)getContext();
if (!Config.isInitialized()) {
Config.init(cdv.getActivity());
}
init(cdv, makeWebViewClient(cdv), makeWebChromeClient(cdv), Config.getPluginEntries(), Config.getWhitelist(), Config.getExternalWhitelist(), Config.getPreferences());
}
}
您可以看到调用了makeWebViewClient
,即使您可能已经设置了自己的客户端
我用以下方法解决了这个问题:
ConfigXmlParser parser = new ConfigXmlParser();
parser.parse(activity);
CordovaInterface cordova = (CordovaInterface) activity;
init(cordova, new WFWebViewClient(cordova, this), makeWebChromeClient(cordova),
parser.getPluginEntries(), parser.getInternalWhitelist(), parser.getExternalWhitelist(),
parser.getPreferences());
并删除了不推荐使用的Config.init(活动)代码>
希望这能帮你省下我今天浪费的时间。谢谢托德!我确实做了一些不同的事情,但问题恰恰是那个。我已经创建了自己的自定义方法makeWebViewClient,它检查是否已经有一个,如果已经有,它将不会替换它。在我的场景中,它解决了这个问题@重写公共CordovaWebViewClient makeWebViewClient(CordovaInterface cordova){如果(this.webViewClient==null){webViewClient=super.makeWebViewClient(cordova);}返回this.webViewClient;}我实际上更喜欢您的解决方案,并且几乎重构了我的解决方案来重写makeWebViewClient
,但是initifnequired
中关于需要init的评论很快让我害怕,只进行了不必要的复杂init调用。我不知道为什么我们必须自己进行配置解析。@ToddT你能详细说明一下你的代码块放在哪里吗?
