I am trying to implement SwipeRefreshLayout in a webview in Xamarin.android but the layout keeps loading infinitely only works well as a progress bar but when swiping to refresh it doesn't work. Please help me fix it.
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.gameofthrones);
myWebClient = new WebClient();
myWebView = FindViewById<WebView>(Resource.Id.webView);
myProgressBar = FindViewById<ProgressBar>(Resource.Id.progressBar);
myswipeRefreshLayout = FindViewById<SwipeRefreshLayout>(Resource.Id.refresher);
myswipeRefreshLayout.SetColorScheme(Resource.Color.Red, Resource.Color.Orange,
Resource.Color.Yellow, Resource.Color.Green,
Resource.Color.Blue, Resource.Color.Indigo,
Resource.Color.Violet);
var toolbar = FindViewById<Toolbar>(Resource.Id.toolbar);
myWebView.Settings.JavaScriptEnabled = true;
myWebView.LoadUrl("http://www.google.com");
myWebView.SetWebViewClient(myWebClient);
//Toolbar will now take on default actionbar characteristics
SetSupportActionBar(toolbar);
SupportActionBar.Title = "GAME OF THRONES";
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
SupportActionBar.SetHomeButtonEnabled(true);
myswipeRefreshLayout.Refresh += MyswipeRefreshLayout_Refresh;
}
private void MyswipeRefreshLayout_Refresh(object sender, EventArgs e)
{
myWebClient.myOnProgressChanged += (int state) =>
{
if (state == 0)
{
(sender as SwipeRefreshLayout).Refreshing = false;
myswipeRefreshLayout.Refreshing = false;
//page loaded no progress bar visible
//myProgressBar.Visibility = ViewStates.Invisible;
}
else
{
(sender as SwipeRefreshLayout).Refreshing = true;
myswipeRefreshLayout.Refreshing = true;
//myProgressBar.Visibility = ViewStates.Visible;
}
};
}
public override bool OnKeyDown(Android.Views.Keycode keyCode, Android.Views.KeyEvent e)
{
if (keyCode == Keycode.Back && myWebView.CanGoBack())
{
myWebView.GoBack();
return true;
}
return base.OnKeyDown(keyCode, e);
}
public override bool OnOptionsItemSelected(IMenuItem item)
{
if (item.ItemId == Android.Resource.Id.Home)
Finish();
return base.OnOptionsItemSelected(item);
}
}
public class WebClient : WebViewClient
{
public delegate void ToggleProgreeBar(int state);
public ToggleProgreeBar myOnProgressChanged;
public override bool ShouldOverrideUrlLoading(WebView view, string url)
{
view.LoadUrl(url);
return true;
}
public override void OnPageStarted(WebView view, string url, Bitmap favicon)
{
if (myOnProgressChanged != null)
{
myOnProgressChanged.Invoke(1);
}
base.OnPageStarted(view, url, favicon);
}
public override void OnPageFinished(WebView view, string url)
{
if (myOnProgressChanged != null)
{
myOnProgressChanged.Invoke(0);
}
base.OnPageFinished(view, url);
}
SwipeRefreshLayout.Refresh get triggered when user down swipes. According to your requirement, when user swipes, you need to manually refresh the webview:
private void SwipeRefresh_Refresh(object sender, System.EventArgs e)
{
webview.LoadUrl(webview.Url);
}
And register myWebClient.myOnProgressChanged event inside OnCreate. So codes should looks like below:
public class MainActivity : Activity
{
WebView webview;
SwipeRefreshLayout mySwipeRefresh;
WebClient myWebClient;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
webview = FindViewById<WebView>(Resource.Id.webview);
webview.Settings.JavaScriptEnabled = true;
webview.LoadUrl("http://www.google.com");
mySwipeRefresh = FindViewById<SwipeRefreshLayout>(Resource.Id.swiperefresh);
myWebClient = new WebClient();
//register myOnProgressChanged here
myWebClient.myOnProgressChanged += (int state) =>
{
if (state == 0)
{
mySwipeRefresh.Refreshing = false;
}
else
{
mySwipeRefresh.Refreshing = true;
}
};
webview.SetWebViewClient(myWebClient);
mySwipeRefresh.Refresh += SwipeRefresh_Refresh;
}
private void SwipeRefresh_Refresh(object sender, System.EventArgs e)
{
//refresh the webview when user swipes.
webview.LoadUrl(webview.Url);
}
}

I have a sample pdf URL "http://www.africau.edu/images/default/sample.pdf". I want to show this pdf file and display in my mobile app using Xamarin.Forms. I tried using webviews and some custom renderers but did not work.
public class PdfViewRenderer : WebViewRenderer
{
internal class PdfWebChromeClient : WebChromeClient
{
public override bool OnJsAlert(Android.Webkit.WebView view, string url, string message, JsResult result)
{
if (message != "PdfViewer_app_scheme:print")
{
return base.OnJsAlert(view, url, message, result);
}
using (var printManager = Forms.Context.GetSystemService(Android.Content.Context.PrintService) as PrintManager)
{
printManager?.Print(FileName, new FilePrintDocumentAdapter(FileName, Uri), null);
}
return true;
}
public string Uri { private get; set; }
public string FileName { private get; set; }
}
protected override void OnElementChanged(ElementChangedEventArgs<WebView> e)
{
base.OnElementChanged(e);
if (e.NewElement == null)
{
return;
}
var pdfView = Element as PdfView;
if (pdfView == null)
{
return;
}
if (string.IsNullOrWhiteSpace(pdfView.Uri) == false)
{
Control.SetWebChromeClient(new PdfWebChromeClient
{
Uri = pdfView.Uri,
//FileName = GetFileNameFromUri(pdfView.Uri)
});
}
Control.Settings.AllowFileAccess = true;
Control.Settings.AllowUniversalAccessFromFileURLs = true;
LoadFile(pdfView.Uri);
}
private static string GetFileNameFromUri(string uri)
{
var lastIndexOf = uri?.LastIndexOf("/", StringComparison.InvariantCultureIgnoreCase);
return lastIndexOf > 0 ? uri.Substring(lastIndexOf.Value, uri.Length - lastIndexOf.Value) : string.Empty;
}
protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
{
base.OnElementPropertyChanged(sender, e);
if (e.PropertyName != PdfView.UriProperty.PropertyName)
{
return;
}
var pdfView = Element as PdfView;
if (pdfView == null)
{
return;
}
if (string.IsNullOrWhiteSpace(pdfView.Uri) == false)
{
Control.SetWebChromeClient(new PdfWebChromeClient
{
Uri = pdfView.Uri,
// FileName = GetFileNameFromUri(pdfView.Uri)
});
}
LoadFile(pdfView.Uri);
}
private void LoadFile(string uri)
{
if (string.IsNullOrWhiteSpace(uri))
{
return;
}
//Control.Resources = new Uri(string.Format("ms-appx-web:///Assets/pdfjs/web/viewer.html?file={0}", string.Format("ms-appx-web:///Assets/Content/{0}", WebUtility.UrlEncode(PdfView.Uri))));

Control.LoadUrl(string.Format("ms-appx-web:///Assets/pdfjs/web/viewer.html?file={0}", string.Format("ms-appx-web:///Assets/Content/{0}", WebUtility.UrlEncode(uri))));
}
}
Your XAML
<WebView x:Name="Webview"
HeightRequest="1000"
WidthRequest="1000"
VerticalOptions="FillAndExpand"/>
Put your Webview source like this
Webview.Source = "https://docs.google.com/gview?
embedded=true&url="+"http://www.africau.edu/images/default/sample.pdf";
In Android
[assembly: ExportRenderer(typeof(CustomWebView), typeof(CustomWebViewRenderer))]
namespace DipsDemoXaml.Droid.Renderer
public class CustomWebViewRenderer : WebViewRenderer
{
public CustomWebViewRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<WebView> e)
{
base.OnElementChanged(e);
if (e.NewElement != null)
{
Control.Settings.AllowUniversalAccessFromFileURLs = true;
Control.Settings.BuiltInZoomControls = true;
Control.Settings.DisplayZoomControls = true;
}
this.Control.SetBackgroundColor(Android.Graphics.Color.Transparent);
}
protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
{
if (e.PropertyName != "Uri") return;
var customWebView = Element as CustomWebView;
if (customWebView != null)
{
Control.LoadUrl(string.Format("file:///android_asset/pdfjs/web/viewer.html?file={0}", string.Format("file:///android_asset/Content/{0}", WebUtility.UrlEncode(customWebView.Uri))));
}
}
}
}
for iOS
[assembly: ExportRenderer(typeof(CustomWebView), typeof(CustomWebViewRenderer))]
namespace DipsDemoXaml.iOS.Renderes
{
public class CustomWebViewRenderer : ViewRenderer<CustomWebView, UIWebView>
{
protected override void OnElementChanged(ElementChangedEventArgs<CustomWebView>
e)
{
base.OnElementChanged(e);
if (Control == null)
{
SetNativeControl(new UIWebView());
}
if (e.OldElement != null)
{
// Cleanup
}
if (e.NewElement != null)
{
var customWebView = Element as CustomWebView;
string fileName = Path.Combine(NSBundle.MainBundle.BundlePath, string.Format("Content/{0}", WebUtility.UrlEncode(customWebView.Uri)));
Control.LoadRequest(new NSUrlRequest(new NSUrl(fileName, false)));
Control.ScalesPageToFit = true;
}
this.Opaque = false;
this.BackgroundColor = Color.Transparent.ToUIColor();
}
}
}
In shared
namespace DipsDemoXaml.Custom.Renderer
{
public class CustomWebView : WebView
{
public static readonly BindableProperty UriProperty =
BindableProperty.Create(nameof(Uri),typeof(string),
typeof(CustomWebView),default(string))
;
public string Uri
{
get => (string) GetValue(UriProperty);
set => SetValue(UriProperty, value);
}
}
}
In XAML You can Call Like this
<renderer:CustomWebView Uri="{Binding SelectedJournal.Uri}" />
I think Problem in your Custom Rendering You can Create a new property like URI in a string and You can Call the URI you need a way to access Android and iOS webview for that you can call android asset pdf viewer for android and for Ios you can pass a new NSUrl to load the pdf inside your app
I want to show a progressbar while the webview gets loaded and hide the progessbar when the webview gets loaded completely.
Here is my Activity.cs
progress = new ProgressDialog(this);
progress.Indeterminate = true;
progress.SetProgressStyle(Android.App.ProgressDialogStyle.Spinner);
progress.SetMessage("Loading... Please wait...");
progress.SetCancelable(false);
progress.Show();
_faq = FindViewById<Android.Webkit.WebView>(Resource.Id.wv_FAQ);
_web.AppWebViewClients(progress);
_web.ShouldOverrideUrlLoading(_faq, _url);
_web.OnPageFinished(_faq, _url);
here is my ResourceWebView.cs
public class ResourceWebView: WebViewClient
{
Android.App.ProgressDialog progress;
public void AppWebViewClients(ProgressDialog progressBar)
{
this.progress = progressBar;
progress.Show();
}
public bool ShouldOverrideUrlLoading(WebView view, String url)
{
view.LoadUrl(url);
progress.Show();
return true;
}
public void OnPageFinished(WebView view, String url)
{
OnPageFinished(view, url);
progress.Hide();
}
}
But this code is not work for me..
Try this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
urlEditText = (EditText) findViewById(R.id.urlField);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new MyWebViewClient());
progress = (ProgressBar) findViewById(R.id.progressBar);
progress.setVisibility(View.GONE);
Button openUrl = (Button) findViewById(R.id.goButton);
openUrl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
String url = urlEditText.getText().toString();
if (validateUrl(url)) {
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
}
private boolean validateUrl(String url) {
return true;
}
});
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
WebViewActivity.this.progress.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
WebViewActivity.this.progress.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}

I am using Tabgroupactivity in Xamarin to develop a droid app.
I have a TabGroupActivity with 4 child activities.
The OnResume() is not being called in any of the child activities.
Can Anyone please help me with the right solution why is it not being called!! or Is there any fault in my code?
TabGroupActivity.cs
namespace RB.Droid
{
[Activity (Label = "TabGroupActivity")]
public class TabGroupActivity : ActivityGroup
{
private List<string> _idList;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
if (_idList == null)
_idList = new List<string> ();
}
public void StartChildActivity (string id, Intent intent)
{
intent.AddFlags (ActivityFlags.ClearTop);
var manager = new LocalActivityManager (this, false);
var window = MainTabActivity.localActivityManager.StartActivity (id, intent);
if (window != null) {
_idList.Add (id);
SetContentView (window.DecorView);
}
}
public override void FinishActivityFromChild (Activity child, int requestCode)
{
var manager = new LocalActivityManager (this, false);
var index = _idList.Count - 1;
if (index < 1) {
Finish ();
return;
}
MainTabActivity.localActivityManager.DestroyActivity (_idList [index], true);
_idList.RemoveAt (index);
index--;
var lastId = _idList [index];
var lastIntent = MainTabActivity.localActivityManager.GetActivity (lastId).Intent;
var newWindow = MainTabActivity.localActivityManager.StartActivity (lastId, lastIntent);
SetContentView (newWindow.DecorView);
}
public override bool OnKeyDown (Keycode keyCode, KeyEvent e)
{
if (keyCode == Keycode.Back) {
return true;
}
return base.OnKeyDown (keyCode, e);
}
public override bool OnKeyUp (Keycode keyCode, KeyEvent e)
{
if (keyCode == Keycode.Back) {
OnBackPressed ();
return true;
}
return base.OnKeyUp (keyCode, e);
}
public override void OnBackPressed ()
{
var length = _idList.Count;
if (length > 1) {
var manager = new LocalActivityManager (this, false);
var current = MainTabActivity.localActivityManager.GetActivity (_idList [length - 1]);
FinishActivityFromChild (current, 0);
}
}
}
}
SettingsActivityGroup.cs
namespace RB.Droid
{
[Activity (Label = "SettingsActivityGroup")]
public class SettingsActivityGroup : TabGroupActivity
{
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Create your application here
StartChildActivity ("Settings", new Intent (this, typeof(Settings)));
}
}
}
Settings.cs
namespace RB.Droid
{
[Activity (Label = "Settings")]
public class Settings : Activity
{
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Create your application here
TextView tv = new TextView (this);
tv.Text = "Settings";
SetContentView (tv);
}
protected override void OnResume ()
{
base.OnResume ();
Toast.MakeText (this, "ON RESUME NOT CALLED", ToastLength.Long);
}
}
}
Use the OnStart Method to do that. We use the this method to load/refresh some ui-data when the view gets displayed.
OnResume: The activity goes in Pause state when another activity comes over it. In this case when user pressed back button then onResume get's called.
More infos and good explanation to activity lifecycle: See this answer
in my activity I have this:
public class MainActivity : Activity
{
RelativeLayout mRelativeLayout;
Button mButton;
private Button mBtnSignUp;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
mRelativeLayout = FindViewById<RelativeLayout>(Resource.Id.mainView);
mButton = FindViewById<Button>(Resource.Id.btnLogin);
mButton.Click += mButton_Click;
mRelativeLayout.Click += mRelativeLayout_Click;
mBtnSignUp = FindViewById<Button> (Resource.Id.button1);
mBtnSignUp.Click += (object sender, EventArgs e) =>
{
//Pull up dialog
FragmentTransaction transaction = FragmentManager.BeginTransaction();
dialog_SignUp signUpDialog = new dialog_SignUp();
signUpDialog.Show(transaction, "dialog fragment");
signUpDialog.mOnSignUpComplete += signUpDialog_mOnSignUpComplete;
};
void signUpDialog_mOnSignUpComplete (object sender, OnSignUpEventArgs e)
{
Thread thread = new Thread (ActLikeARequest);
thread.Start ();
}
private void ActLikeARequest()
{
Thread.Sleep (3000);
}
And in the dialog I have:
public class OnSignUpEventArgs : EventArgs
{
private string mFirstName;
private string mEmail;
private string mPassword;
public string FirstName
{
get{ return mFirstName; }
set{ mFirstName=value;}
}
public string Email
{
get{ return mEmail; }
set{ mEmail=value;}
}
public string Password
{
get{ return mPassword; }
set{ mPassword=value;}
}
public OnSignUpEventArgs (string firstName, string email, string password) : base()
{
FirstName = firstName;
Email = email;
Password = password;
}
}
class dialog_SignUp:DialogFragment
{
private Button mBtnSignUp;
private EditText mFirstName;
private EditText mEmail;
private EditText mPassword;
public event EventHandler<OnSignUpEventArgs> mOnSignUpComplete;
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
var view = inflater.Inflate (Resource.Layout.dialog_sign_up, container, false);
mBtnSignUp = view.FindViewById<Button> (Resource.Id.btnDialogEmail);
mFirstName = view.FindViewById<EditText> (Resource.Id.txtFirstName);
mEmail = view.FindViewById<EditText> (Resource.Id.txtEmail);
mPassword = view.FindViewById<EditText> (Resource.Id.txtPassword);
mBtnSignUp.Click += mBtnSignUp_Click;
return view;
}
void mBtnSignUp_Click (object sender, EventArgs e)
{
//User has clicked the sign up button
mOnSignUpComplete.Invoke (this, new OnSignUpEventArgs(mFirstName.Text, mEmail.Text, mPassword.Text));
this.Dismiss ();
}
public override void OnActivityCreated (Bundle savedInstanceState)
{
Dialog.Window.RequestFeature (WindowFeatures.NoTitle); //Sets the title bar to invisible
base.OnActivityCreated (savedInstanceState);
Dialog.Window.Attributes.WindowAnimations = Resource.Style.dialog_animation; //Set the animation
}
}
The question is, how can I pass data(strings) from the activity into the dialog, so that when it is called, the TextViews get the data I'm passing?
Is it something to add in the actitity, but what?
i think you need to be able to accept a parameter in your dialog_signup.
class dialog_SignUp:DialogFragment
{
private Button mBtnSignUp;
private EditText mFirstName;
private EditText mEmail;
private EditText mPassword;
String parameter="";
public event EventHandler<OnSignUpEventArgs> mOnSignUpComplete;
public dialog_SignUp(String parameterIn){
parameter=parameterIn;
}
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
var view = inflater.Inflate (Resource.Layout.dialog_sign_up, container, false);
mBtnSignUp = view.FindViewById<Button> (Resource.Id.btnDialogEmail);
mFirstName = view.FindViewById<EditText> (Resource.Id.txtFirstName);
mFirstName.setText(parameter);
mEmail = view.FindViewById<EditText> (Resource.Id.txtEmail);
mPassword = view.FindViewById<EditText> (Resource.Id.txtPassword);
mBtnSignUp.Click += mBtnSignUp_Click;
return view;
}
then replace dialog_SignUp signUpDialog = new dialog_SignUp(); with dialog_SignUp signUpDialog = new dialog_SignUp(stringToSend);
Keep in mind that you can always use The Application class to define a variable there.
namespace YourNamespace
{
[Application]
public class App : Application
{
public ParseObject currentBusiness { get; set;}
public App (IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference, transfer)
{
}
public override void OnCreate ()
{
base.OnCreate ();
currentBusiness = new ParseObject ("Business");
}
}
}
Then you can access it from evewhere in that way:
App _app = (App)Application.Context;
var curentBusiness = _app.currentBusiness;
You can use Property feature of Class.
Dialog Fragment Code
class Error : DialogFragment
{
public string getErrorMsg { get; set; } // this gets the message
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.Inflate(Resource.Layout.Error, container, false);
TextView text = view.FindViewById<TextView>(Resource.Id.txtError);
text.Text = getErrorMsg; //here the message is set to the TextView
return view;
}
}
Calling Method
FragmentTransaction transaction = FragmentManager.BeginTransaction();
Error obj = new Error();
obj.Cancelable = false;
obj.getErrorMsg = passMyString; // in this line you send message to The Class
obj.Show(transaction, "error");
Hi I want to add pull to refresh on my apps using this component PullToResharp, The project is great but im having problem adding custom listview in fragment, does anyone here done this before help me resolve it, thanks.
