Android Soft Key Board/Soft Input Window Customization

This code log entry is regarding adding Action key to Xamarin.Android soft keyboard. When I tried to do this in one of my project,faced a little problem,So updating here to avoid in future ;( and may helpful to somebody those who are looking for the same.
To Add "search" to softkeyboard.

      <EditText     
        android:id="@+id/myEdtTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="text" 
        android:imeActionId="@+id/ImeSearch"
        android:imeOptions="actionSearch"
        android:imeActionLabel="Search"
        android:textSize="22dp" />

Here we need to mention inputType [where i did mistake]. Mention the text in "imeActionLabel" attribute.

If you want Show only the search symbol instead of text, just remove the

'android:imeActionLabel="Search"'

Lenova tab 7-kitkat

YU-Lolipop

or Add imeActionOption programmatically,

txtSearch.SetImeActionLabel ( "Search" , ImeAction.Search );

You can Detect the seach action key pressed using below line of code,

txtSearch.KeyPress+= delegate(object sender , View.KeyEventArgs e )
            {
                InputMethodManager inputManager = (InputMethodManager)this.GetSystemService (Context.InputMethodService);
                //Hide softinputwindow    
                inputManager.HideSoftInputFromWindow (this.CurrentFocus.WindowToken, HideSoftInputFlags.NotAlways);
                if ( e.KeyCode == Keycode.Enter && e.Event.Action == KeyEventActions.Down )
                { 
                    Console.WriteLine("Search pressed");
                }
            };

In the same way we can set "Done" action also

 <EditText
    android:id="@+id/myEdtTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:imeActionId="@+id/imeSearch"
    android:imeOptions="actionDone" 
    android:textSize="22dp" />
