How do you allow users to copy and paste from an Xamarin.Forms Label?
Click on the text on any platform the default settings don\'t allow highlighting and therefore cop
Since I_Khanage provided only a half solution, I will post the full solution.
IClipboardService
should be implemented for all the targeting platforms, in my case it is Android
and iOS
:
public interface IClipboardService
{
string GetTextFromClipboard();
void SendTextToClipboard(string text);
}
// iOS
public class ClipboardService : IClipboardService
{
public string GetTextFromClipboard() => UIPasteboard.General.String;
public void SendTextToClipboard(string text) => UIPasteboard.General.String = text;
}
// Android
public class ClipboardService : IClipboardService
{
public string GetTextFromClipboard()
{
var clipboardmanager = (ClipboardManager)Forms.Context.GetSystemService(Context.ClipboardService);
var item = clipboardmanager.PrimaryClip.GetItemAt(0);
var text = item.Text;
return text;
}
public void SendTextToClipboard(string text)
{
// Get the Clipboard Manager
var clipboardManager = (ClipboardManager)Forms.Context.GetSystemService(Context.ClipboardService);
// Create a new Clip
var clip = ClipData.NewPlainText("YOUR_TITLE_HERE", text);
// Copy the text
clipboardManager.PrimaryClip = clip;
}
}
The code is available on github.
Now just add a GestureRecognizer
in order to trigger the tap event.
P.S.: Clipboard service is now available as a part of Xamarin.Essentials package, so there is no need to write one yourself.
What you could do is wrap your label in a gesture recogniser:
<Label Text="Test">
<Label.GestureRecognizers>
<TapGestureRecognizer
Tapped="YourFunctionToHandleMadTaps"
NumberOfTapsRequired="1"
/>
</Label.GestureRecognizers>
</Label>
This will trigger your function and in that function you can get to the clipboard and copy and paste. However I haven't been able to find an easy way to access the clipboard in Xamarin.Forms so you have to use the dependency service.
Xamarin.Forms Dependency service documentation
Here is how I did my clipboard data access. Please note that in my project I only needed to nab data from the clipboard so this code just shows you how to access the clipboard data:
Create an interface in you X.F project eg:
public interface IClipBoard
{
String GetTextFromClipBoard();
}
Implement the interface in your mobile projects:
Android:
public string GetTextFromClipBoard ()
{
var clipboardmanager = (ClipboardManager)Forms.Context.GetSystemService (Context.ClipboardService);
var item = clipboardmanager.PrimaryClip.GetItemAt(0);
var text = item.Text;
return text;
}
iOs:
public string GetTextFromClipBoard ()
{
var pb = UIPasteboard.General.GetValue ("public.utf8-plain-text");
return pb.ToString ();
}
Don't forget to add the Assembly bits at the top:
iOs: [assembly: Dependency (typeof (ClipBoard_iOs))]
Android: [assembly: Dependency (typeof (ClipBoard_Droid))]
Call the dependency service from you X.F function
public void YourFunctionToHandleMadTaps(Object sender, EventArgs ea)
{
var clipboardText = DependencyService.Get<IClipBoard> ().GetTextFromClipBoard ();
YourFunctionToHandleMadTaps.Text = clipboardText;
}
