Xamarin: Saving and loading preferences in Android

Loading and saving preferences on Xamarin.Android should be done through the ISharedPreferences interface.

Here’s a quick sample to save preferences:

	private void SavePreferences(){
	var prefs = this.GetSharedPreferences("RunningAssistant.preferences", FileCreationMode.Private);
	var editor = prefs.Edit ();
	editor.PutString ("Distance", distanceText.Text);
	editor.PutString ("Hours", hoursText.Text);
	editor.PutString ("Minutes", minutesText.Text);
	editor.PutString ("Seconds", secondsText.Text);
	editor.Commit ();
	}

And another one to load them again:

	private void LoadPreferences(){
	var prefs = this.GetSharedPreferences("RunningAssistant.preferences", FileCreationMode.Private);
	if (prefs.Contains("Distance")) {
	distanceText.Text = prefs.GetString ("Distance","");
	}
	if (prefs.Contains("Hours")) {
	hoursText.Text = prefs.GetString ("Hours","");
	}
	if (prefs.Contains("Minutes")) {
	minutesText.Text = prefs.GetString ("Minutes","");
	}
	if (prefs.Contains("Seconds")) {
	secondsText.Text = prefs.GetString ("Seconds","");
	}
	}
