Hi All, I have created a new simple Dot Net project with a separate UI and ViewModel project for Android. I have used a simple Xamarin.Android EditText control to rendered in Forms control. In some scenarios, I will handle the keyboard manually. So I have used the below codes to handle the keyboard. But the Context was not cast to Activity. The specified case was not found exception has occurred. Window window = ((Activity) this .Context).Window; InputMethodManager mgr = (InputMethodManager)((Activity) this .Context).GetSystemService(Context.InputMethodService); if (window != null ) { window.SetSoftInputMode(SoftInput.StateHidden); mgr.HideSoftInputFromWindow( this .WindowToken, 0); } I have attached the simple project to this post. Please help me to use the keypad manually. Thanks in advance.

Hi All,

I have created a new simple Dot Net project with a separate UI and ViewModel project for Android. I have used a simple Xamarin.Android EditText control to rendered in Forms control. In some scenarios, I will handle the keyboard manually. So I have used the below codes to handle the keyboard. But the Context was not cast to Activity. The specified case was not found exception has occurred.

Window window = ((Activity)this.Context).Window;
InputMethodManager mgr = (InputMethodManager)((Activity)this.Context).GetSystemService(Context.InputMethodService);
if (window != null)
{
window.SetSoftInputMode(SoftInput.StateHidden);
mgr.HideSoftInputFromWindow(this.WindowToken, 0);
}
