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

  1. <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">  
  2.     <TextView android:id="@+id/label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Type Here.." />  
  3.     <EditText android:id="@+id/entry" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/label" />  
  4.     <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" />  
  5.     <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>  
Xamarin

Step 15

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

MainActivity.cs

  1. protected override void OnCreate(Bundle bundle) {  
  2.         base.OnCreate(bundle);  
  3.         // Set our view from the "main" layout resource  
  4.         SetContentView(Resource.Layout.Main);  
  5.     } // This is just a sample script. Paste your real code (javascript or HTML) here.  
  6. if ('this_is' == /an_example/) {  
  7.     of_beautifier();  
  8. else {  
  9.     var a = b ? (c % d) : e[f];  
  10. }  
Xamarin

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.
