Create A Relative Layout In Xamarin Android App Using Visual Studio 2015

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. In Xamarin Studio, Visual Studio is also available.

Prerequisites

Visual Studio 2015 Update 3.

The steps, given below are required to be followed in order to create a relative layout in Xamarin Android app, using Visual Studio 2015.

Xamarin

Step 11

You need to edit the Plain Text (EditText) Id's value (EX: android:id="@+id/entry" ).

Xamarin

Step 12

You need to edit the button's Id value (EX: android:text="Submit" ).

Xamarin

Step 13

You need to edit the button's Id value and Text value (EX: android:id="@+id/ok" android:text="Cancel").

Xamarin

Step 14

In this step, go to the Main.axml page source panel. Note Id values.

Main.axml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:minWidth="25px" android:minHeight="25px">
<TextView android:id="@+id/label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Type Here.." />
<EditText android:id="@+id/entry" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/label" />
<Button android:id="@+id/ok" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/entry" android:layout_alignParentRight="true" android:layout_marginLeft="10dip" android:text="Cancel" />
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toLeftOf="@id/ok" android:layout_alignTop="@id/ok" android:text="Submit" /> </RelativeLayout>

Step 15

In this step, go to MainActivity.cs page and write the code, mentioned below between OnCreate() Method.

MainActivity.cs

protected override void OnCreate(Bundle bundle) {
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
} // This is just a sample script. Paste your real code (javascript or HTML) here.
if ('this_is' == /an_example/) {
of_beautifier();
} else {
var a = b ? (c % d) : e[f];
}

Step 16

If you have Android Virtual device, run the app on it, else connect your Android phone and run the app on it.

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 Run option.

Xamarin

Output

After a few seconds, the app will start running on your phone.

You will see the relative layout will work successfully.
