I have a webpage that has a "Print" button and works normally when using Any Browser on mobile phone.
But when using the webview, is not working. Its like not firing.
For java
private void createWebPrintJob(WebView webView) {
PrintManager printManager = (PrintManager) this.getSystemService(Context.PRINT_SERVICE);
PrintDocumentAdapter printAdapter = webView.createPrintDocumentAdapter();
String jobName = getString(R.string.app_name) + " Print Test";
printManager.print(jobName, printAdapter, new PrintAttributes.Builder().build());
}
//perform click pdf creation operation on click of print button click
// Use this on main activity class tag
public void printPDF(View view) { createWebPrintJob(myWebView); }
For Xml Create Button
android:onClick="printPDF"

I have created an app using MudBlazor template.
All is ok, I use MudBlazor Snackbar and in MainLayout I use
and button on it.
On click I call a function
ShowNotification("BottomRight")
private void ShowNotification(string position)
{
Snackbar.Clear();
Snackbar.Configuration.PositionClass = position;
Snackbar.Add(message, Severity.Normal);
}
I'd like to show notifications in the Bottom-Right of the Browser window but it displayed in left top corner because it is MudAppBar.
How to display notification in the Bottm-right of browser window?
You should not be using "BottomRight" but Defaults.Classes.Position.BottomRight instead:
#inject ISnackbar Snackbar
<MudButton
OnClick="#this.ShowMessage"
Color="Color.Success">
Show message
</MudButton>
#code {
void ShowMessage()
{
this.Snackbar.Clear();
this.Snackbar.Configuration.PositionClass = Defaults.Classes.Position.BottomRight;
this.Snackbar.Add("Wazzup?", Severity.Normal);
}
}

I need to pass some additional information with a button press. From what I could gather reading on the web I should use a button tag.
So far I have this
Button button = new Button(this);
button.Text = "Test Button";
button.SetBackgroundColor(Android.Graphics.Color.Black);
button.SetTextColor(Android.Graphics.Color.White);
button.Tag = "hello";
button.Click += ClickEvent;
And this is the handler:
public void ClickEvent(object sender, EventArgs e)
{
Android.Widget.Button button = (Android.Widget.Button)sender;
var test = button.Tag;
}
This works, but I need to be able to pass 3 ints of data. I have tried using an array but I have no idea how to read it in the handler as it comes back as a java.object.
Can anyone please push me in the right direction?
{final Button tab3button2 = view findViewById(R.id.button2); View.OnClickListener() { #Override pubilc void onClick (View v)
I have tried searching for answers but all to no avail.
Just copy the code for on click on source code, and you must have a section like bindview or webview to get at the id of widget. Then just enter I'd, make sure it's different then all others on same page.
Here is what you need, I edited your code:
final Button tab3button2 = view findViewById(R.id.button2);
tab3button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View _view) {
here put the blocks that will be executed when the button gets clicked
}
});
it's recommended to add this code in the onCreate event, but if this Button is in a ListView custom view then add it in the onBindCustomView event.
I am trying to create a custom control for webview, i am trying to get a checkbox inside a webview Reason :- we have a bunch of text to be displayed and unless the user reaches the end of the scroll he cannot move to the next page and at the end of the scroll there is a checkbox where user has to check the the checkbox and then he can process. here i have tried putting the checkbox and webview inside the stacklayout but the issue is webview have its own scroll bar and and stacklayout scroll bar does not work when a user try to scroll as the webview scroller scrolls out also when i try to close the Webview Page with back button the webview gets close and not the page
i am not sure what approach should i apply here.
i am getting my html data from my webapi.
anyone with some solution would be appreciable
here is my custom renderer which i have wrote but the piece missing here is how can i add another xamarin control inside this
public class CustomPdfViewRenderer : WebViewRenderer
{
public CustomPdfViewRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<WebView> e)
{
base.OnElementChanged(e);
if (Control != null)
{
Control.Settings.BuiltInZoomControls = true;
Control.Settings.DisplayZoomControls = false;
Control.Settings.LoadWithOverviewMode = true;
Control.Settings.UseWideViewPort = true;
}
}
}
You can try the following approach:
Add checkbox to HTML
When the user check checkbox call some JavaScript function
When JavaScript function is called, call C# function (Xamarin) which will enable the user to process to the next page (or some other Xamarin side stuff)
Here is how you can call C# function from JavaScript :HybridWebView
I need to add a custom tab item into my TabbedPage. That shouldn't be a page but an overlay view. It is "More" item for the bottom menu opening a more items menu over the currently shown page.
So far I found the following solution:
protected override void OnCurrentPageChanged()
{
base.OnCurrentPageChanged();
if (this.isInitialized)
{
if (CurrentPage.Title == "More")
{
CurrentPage = this.lastSelectedPage;
}
}
this.lastSelectedPage = CurrentPage;
}
It's enough to prevent opening the corresponding fake page. After this I need to show an overlay view and have no item how to do it from the tabbed page.
Another solution I'm working out now is to write a custom renderer for my tabbed page and manage all the custom work there. The question in this case is how to show my custom view over the existing content. I tried AddView (iOS) in the renderer but getting runtime exception.
public override void ItemSelected(UITabBar tabbar, UITabBarItem item)
{
base.ItemSelected(tabbar, item);
var view = new UILabel()
{
Text = "Test"
};
View.Add(view);
}
