Building the Android ChatActivity

Let's move back to the Android implementation. This part is easy, we have already mapped the UI logic to the ChatPresenter, so let's get straight into building the interface. Add a new file to the Views folder in the Chat.Droid project, call it ChatActivity.cs, and implement the first part:

[Activity(Label = "Chat", ScreenOrientation = ScreenOrientation.Portrait)]
     public class ChatView : ListActivity, ChatPresenter.IChatView
     {
         #region Private Properties
         private ChatPresenter _presenter;
         private LinearLayout _scrollViewInnerLayout;
         private EditText _editText;
         private long _lastSendClick = 0;
         private int _width;
         private float _currentTop;
         private bool _dialogShown = false;  
       #endregion  
         #region Protected Methods
         protected override void OnCreate(Bundle bundle)
         {
      ...
