Creating An AutoLink Using TextView In Xamarin Android App

Introduction

Xamarin is a platform to develop cross-platform and multi-platform apps (for example, Windows phone, Android, iOS). In Xamarin platform, the code sharing concept is used. The Xamarin Studio is available in Visual Studio too.

Prerequisites

Visual Studio 2015 Update 3.

The steps, given below, are required to be followed in order to create an autoLink using TextView in a Xamarin Android app.

Step 1

Click File--> select New--> select Project. Or, click (Ctrl+Shift+N).

Step 2

After opening the New Project, go to Installed >> Templates >> Visual C# >> Android >> Blank App (Android).

Now, give your Android app a name (Ex:sample) and give the path of your project. Afterwards, click OK.

Step 4

The Main.axml file will open the main page designer. In this page, you can select the mode (Designer or Source) as per your choice.

Next, delete the default "Hello World" button. For this, go to the source panel and delete the button code from there. Similarly, delete the C# button code from the MainActivity.cs page.

Step 5

Now, go to the Toolbox window. Now, scroll down to all the tools and controls. Drag and drop the TextView.

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="Hello">Hello World, Click Me!</string>
<string name="ApplicationName">Auto_Link</string>
<string name="website">www.xamarin.com</string>
</resources>

Step 10

In this step, go to the Main.axml page Source Panel and note down the TextView id value.

Main.axml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:minWidth="25px" android:minHeight="25px">
<TextView android:text="@string/website" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/textView1" android:autoLink="web" /> </LinearLayout>

Step 11

Go to the MainActivity.cs page in Solution Explorer. Write the following code in OnCreate() Method.

MainActivity.cs

protected override void OnCreate(Bundle bundle) {
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
}

Step 12

If you have Android Virtual device, run the app on it. Else, connect your Android phone and run the app in that. Simply, connect your phone and go to Visual Studio. The connected phone will show up in the Run menu (Ex LENOVO A6020a40(Android 5.1-API 22)).

Click the Run option.
