Xamarin Android: Hide Keyboard on Fragment

I have two fragments on a viewpager. Since one fragment has EditTexts on it and the other has just graphics on it, I would like to hide the keyboard when I switch onto the graphic fragment.

Implement ViewPager.IOnPageChangeListener in your xxxxActivity( which contains the ViewPager). And use addOnPageChangeListener( setOnPageChangeListener was deprecated in API level 24.1.0.) to add listener on your ViewPager.

In the OnPageSelected method:

public void OnPageSelected(int position)
{

    if (position == 0)
    {
        // because the keyboard has been forced to hide in graphic fragment,
        // when you back to edittext fragment, you need force to show it.
        EditTextFragment.showKeyboard();
    }
    else if (position == 1)
    {
        //In your graphic fragment, hide the keyboard.
            var im = ((InputMethodManager)GetSystemService(Android.Content.Context.InputMethodService));

            if (CurrentFocus!= null)
            {
                im.HideSoftInputFromWindow(CurrentFocus.WindowToken, HideSoftInputFlags.None);
            }
    }
}

EditTextFragment.showKeyboard(); method:

    if (editText.RequestFocus())
    {
        InputMethodManager imm = (InputMethodManager)Activity.GetSystemService(Android.Content.Context.InputMethodService);
        imm.ShowSoftInput(editText,ShowFlags.Implicit );
    }

You could use a static method for this in a sort of Utils class inside your Xamarin.Android project. Might look kind of like this:

public static class Utils
{
    public static void HideKeyboard(Activity context)
    {
        var imm = (InputMethodManager)context.GetSystemService(Context.InputMethodService);
        int sdk = (int)Build.VERSION.SdkInt;

        if (sdk < 11)
        {
            imm.HideSoftInputFromWindow(context.Window.CurrentFocus.WindowToken, 0);
        }
        else
        {
           imm.HideSoftInputFromWindow(context.CurrentFocus.WindowToken, HideSoftInputFlags.NotAlways);
        }
    }
}

Take a look at GetSystemService(java.lang.String) and the InputMethodManager class.
