I just got into Android Studio and followed the examples from the Android Getting Started lessons.
https://developer.android.com/training/basics/firstapp/starting-activity.html
On this page, there is this line, that just didn't work for me.
TextView textView = findViewById(R.id.textView);
Writing this, Android Studio tells me:
"Incompatible Types
Required: android.widget.TextView
Found: android.view.View"
Now, I can't imagine that there's a mistake on the official page, but it only works for me, if I write.
TextView newView = (TextView) findViewById(R.id.textViewNew);
Also, I checked multiple times, that the textViewNew is a TextView widget, but it is.
So, what is going on and where is the mistake?
Thanks

I am developing Xamarin forms app and my app seems with safe area set in top. But need to ignore it.
Current scenario:

After set safe area as true output come as below,

You can do it from XAML like this
xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
ios:Page.UseSafeArea="true"
Please Refer to Making iOS 11 Even Easier with Xamarin.Forms
We use Platform-Specifics to implement it.
Before iOS 11
On<Xamarin.Forms.PlatformConfiguration.iOS>().SetUseSafeArea(true);
iOS 11 or newer
var safeInsets = On<Xamarin.Forms.PlatformConfiguration.iOS>().SafeAreaInsets();
safeInsets.Left = 24;
this.Padding = safeInsets;
It's necessary to create or configure LaunchScreend.storyboard.
Use this code, change splash_screen for your image.
Go to top constraint and make second Item constraint superview.Top
public ItemsPage() {
InitializeComponent();
On<Xamarin.Forms.PlatformConfiguration.iOS> ().SetUseSafeArea(true);
}
I am currently developing a Xamarin.Forms application. I am using IconizePlugin. The app is tabbedPage based and on toolbar I'm trying to include icons for some actions.
This is whay I'm getting:
Icons are showing well and in Xamarin.iOS gets the click event, while it is not working in Xamarin.Droid.
I included the corresponding nugets and followed every steps told in documentation and can't archive this. Other iconize controls in Droid are working fine except the IconToolbarItem.
Please help!
The workaround I found was to declare de IconToolbarItem in the c# code instead of xaml. Although I don't know why it wasn't working while on xaml.
Declaring the item li
ToolbarItems.Add(new IconToolbarItem
{
Icon = "fa-plus",
IconColor = Color.White,
Command = new Command(this.addBono)
});
I want to create a Xamarin Forms Editor Control that changes its height when it gets filled(Adds a new line when space in previous line finished). I'm only interested in WinPhone and Android Platfroms.
The Editor itself doesn't support such property.
I know that the Android native control (EditText) supports it (Not sure about the WinPhone variant, TextBox). But I'm not sure how to implement it.
It will be very helpful if someone can explain me how to create the renderers for these platforms.
Edit
I found this partial solution, it kind of works fine but it is not so natural(as for example EditText in Android).
class RoundedEditor : Editor
{
public RoundedEditor()
{
this.TextChanged += (sender, e) => { this.InvalidateMeasure(); };
}
}
I'll be glad if someone will provide a better solution.
Edit 2
Here are the results of how it works now:
UWP
Writing first line:
pressing enter:
The previous line is not showed completely as I would like.
Android
In android it actually works great:
You will have to implement a custom Android EditText, and then use it for your XamarinForms control (by implementing a custom renderer for it)
Take a look at this implementation of resizable EditText:
https://github.com/ViksaaSkool/AutoFitEditText
You'd have to translate it to C# obviously, but its a great start point.
Before upgrading to XCode 8 and subsequently Appium 1.6 and IOS 10 for some appium tests, I used to be able to use the below XPath to capture the main text in an alert.
#iOSFindBy(xpath = "//UIAAlert/UIAScrollView/UIAStaticText[2]")
private MobileElement alertText;
However something has changed and this no longer works. I would still like to be able to assert on the alert text and don't want to use the IOSMobileCapabilityType.AUTO_DISMISS_ALERTS capability.
Has anyone found a way to get at the alert text?
Bonus question: Where is all this XPath documented? I found it on some random forum, but I can't find any official documentation or figure out how it relates to a captured View Hierarchy in XCode.
Answering my own question in case it helps anyone else.
Due to the appium inspector not working with XCode8, the best way to print the screen layout XML is just to do a System.out.println(driver.getPageSource());
Then you can follow the structure and do something like
#iOSFindBy(xpath = "//XCUIElementTypeAlert//XCUIElementTypeStaticText[2]")
private MobileElement alertText;
I got that from this question: Finding elements by xpath in Appium using XCUITEST driver
Hello Everyone I want to share the Text on Xamarin Form using Library plugin.share.

You want to take a look at UIActivityViewController, you can find the documentation here https://developer.xamarin.com/api/type/MonoTouch.UIKit.UIActivityViewController/
And Xamarin.Forms specific example http://devcenter.wintellect.com/jwood/implementing-sharing-in-xamarin-forms
This is a bit old, but I was having a similar issue and was able to resolve it.
First of all, you need to add the plugin Plugin.Share to ALL Xamarin.Forms projects (Portable, iOS, Android, UWP).
In the class that references the share code, add...
using Plugin.Share;
using Plugin.Share.Abstractions;
CrossShare.Share() doesn't work with strings, directly. You need to new up a ShareMessage.
var title = "Title For The Share";
var message = "Text to share.";
await CrossShare.Current.Share(new ShareMessage { Text = message, Title = title });
I can't say specifically to iOS, as I don't have a Mac and can't test that project, but Android and Windows 10 is working.
