c# - Xamarin.form setpage not worked second time -

-

I create a new mobile app using the xamarin form. I have to create two page login screens and home screens. I get a sample from

but when I make the same one can not go to another page. It always keeps the login page.

In my Android main activity code 

  Public category Main Activity: Android Attachment, Login Manager {Secure Override Uncharted (Bundle Bundle) {base.OnCreate (bundle); Xamarin.Forms.Forms.Init (this, bundle); SetPage (App.GetLoginPage (this)); // Setpage (App.GetLoginPage (this)); } #region ILoginManager Implementation Public Zero ShowMainPage () {Set Page (App.GetHomePage (this)); } Public Zero Logout () {Set Page (App.GetLoginPage (this)); } #endregion}   
 The setPage method is called the second time but the page content has not been replaced by any one   
 
 
 There is a work around the second set page problem with Android. Create a second interface and start a new activity instead of using the page set on existing activity where new activity sets the on-crayt page of the call and completes the current activity.  
  App.cs     Public Static ILOGinManager LoginManager; Public stable IAppNavigation SplashManger; Public static page GetLoginPage (IoLOGIN Manager Account) {LoginManager = lmanager; Return new page_group (); } Public Static Page GetShowSplashPage (IAppNavigation iSplashNavigation) {SplashManzer = IceSpaceNation; Return a new page (); } {Activity (label = "", main lantern = true, configuration change = config change).    Screencases | configuration changes. Orientation]] Public Class Main Activity: Android Attachivity, IAPNavigation {Safe Override Uncorrect (Bundle Bundle) {//Window.RequestFeature(WindowFeatures.NoTitle); Base.OnCreate (bundle); Xamarin.Forms.Forms.Init (this, bundle); SetPage (App.GetShowSplashPage (this)); } Public Zero GetLoginPage () {StartActivity (new intent (this, LoginActivity)); End(); }   Android login activity   
  [activity (label = "", configuration change = configuration squans. Screensis | config changelog Orientation]] Public Class Login Activity: Android Attachti, iLogin Manager {Secure OpaRide Zero Noncrit (bundle bundle) {base.OnCreate}; Xamarin.Forms.Forms.Init (this, bundle); SetPage (App.GetLoginPage (This));} Public Zero GetMainMenu () {StartActivity (New Intent (Type, MainMenuActivity); End ();}   
 In iOS You do not need to do anything special, just apply all the necessary interfaces that you use in App Delegate.  
  iOS App Delay   
 < Code> [Register ("Appadulate")] Public Partial Class App Dealitat: UIPA Application DeliGet, iLogin Manager, IAPNevolution {// Class-level Announcements UI Window Window; Public Override Balls Finish Launching (UIApplication App, NSDictionary Option) {Forms.Init (); Vs DOE = new UIWindow (UIScreen.MainScreen.Bounds); Window.RootViewController = App.GetShowSplashPage (this) .CreateViewController (); Window.MakeKeyAndVisible (); Back true; } Public Zero GetMainMenu () {window.RootViewController = App.GetMainMenu () CreateViewController (); Window.MakeKeyAndVisible (); } Public Zero GetLoginPage () {window.RootViewController = App.GetLoginPage (this) .CreateViewController (); Window.MakeKeyAndVisible (); }

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

python - 'NoneType' object is not callable using 'find_all' in BeautifulSoup -

Here's my code using find_all, but this is my code. Works great with: (): To get beautiful suits R = requests from beautiful soup imports to import. (URL_DEFINED) Print Rustusodod Soup = Beautiful Soup (Rtext) Print soup.fund_all ('ul') What I found: Tracebacks (Most recent call end): File "scraper.py", line 1 9, & lt; Module & gt; Print soup.find_all ('ul') TypeError: The 'NoneType' object is not worth the corner It seems that you are using Sundersup version 3, in which a slightly different naming convention is used, such as: .findAll , while SunderSupo 4 standardized naming, like more PEP8, Such as: .find_all (but retains the old naming for previous compatibility) Note that soup ('ul') is equal to both search for all . To download and install, install pipes PrettySpeed ​​4 . Then to change your import: import from bs4 BeautifulSoup Then you are good go.
