问题描述

我将Visual Studio 2015与Xamarin一起使用. 我将我的项目命名为"Phoneword" 我在Xamarin的网站上看到了诸如教程/示例之类的代码.

I use Visual Studio 2015 with Xamarin. I'm naming my project "Phoneword" I see this code such as tutorial/example on Xamarin's site.

TranslateButton 和 CallButton 成员的错误相同.

MainActivity.cs

using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;

namespace Phoneword
{
[Activity(Label = "Phoneword", MainLauncher = true)]
public class MainActivity : Activity
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);

        // Our code will go here
        // Get our UI controls from the loaded layout:
        EditText phoneNumberText = (EditText)FindViewById(Resource.Id.PhoneNumberText);
        Button translateButton = FindViewById<Button>(Resource.Id.TranslateButton);
        Button callButton = FindViewById<Button>(Resource.Id.CallButton);

        // Disable the "Call" button
        callButton.Enabled = false;

        // Add code to translate number
        string translatedNumber = string.Empty;

        translateButton.Click += (object sender, EventArgs e) =>
        {
            // Translate user's alphanumeric phone number to numeric
            translatedNumber = Core.PhonewordTranslator.ToNumber(phoneNumberText.Text);
            if (String.IsNullOrWhiteSpace(translatedNumber))
            {
                callButton.Text = "Call";
                callButton.Enabled = false;
            }
            else
            {
                callButton.Text = "Call " + translatedNumber;
                callButton.Enabled = true;
            }
        };

        callButton.Click += (object sender, EventArgs e) =>
        {
            // On "Call" button click, try to dial phone number.
            var callDialog = new AlertDialog.Builder(this);
            callDialog.SetMessage("Call " + translatedNumber + "?");
            callDialog.SetNeutralButton("Call", delegate {
                // Create intent to dial phone
                var callIntent = new Intent(Intent.ActionCall);
                callIntent.SetData(Android.Net.Uri.Parse("tel:" + translatedNumber));
                StartActivity(callIntent);
            });
            callDialog.SetNegativeButton("Cancel", delegate { });

            // Show the alert dialog to the user and wait for response.
            callDialog.Show();
        };
    }

}
}
