Question

从MainActivity.cs到AnotherActivity.cs

  public static string hisname;
    public static string hername;
    private Handler mHandler = new Handler();
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetContentView(Resource.Layout.Register1);
        // Create your application here
        EditText her = FindViewById<EditText>(Resource.Id.editTextHername);
        EditText his = FindViewById<EditText>(Resource.Id.editTextUrname);
        //RotateAnimation anim = new RotateAnimation(0f, 350f, 15f, 15f);
        //anim.setInterpolator
        //anim.setRepeatCount(Animation.INFINITE);
        //anim.Duration(700);
        //splash.StartAnimation(anim);


        WindowRotationAnimation q = new WindowRotationAnimation();
        Button getStarted = FindViewById<Button>(Resource.Id.myButton);
        getStarted.Click += delegate
        {
            var intent = new Intent(this, typeof(CalculateActivity));
            intent.PutExtra("yourname", ""+hisname);
            intent.PutExtra("GFname", "" + hername);
            StartActivity(intent);

        };
    }
}

Answer 1

尝试使用以下

var herName = her.text;


vad hisName = his.text;

并添加到intent.putextra方法。

Answer 2

  public static string hisname;
public static string hername;
private Handler mHandler = new Handler();
protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    SetContentView(Resource.Layout.Register1);
    // Create your application here
    EditText her = FindViewById<EditText>(Resource.Id.editTextHername);
    EditText his = FindViewById<EditText>(Resource.Id.editTextUrname);
    //RotateAnimation anim = new RotateAnimation(0f, 350f, 15f, 15f);
    //anim.setInterpolator
    //anim.setRepeatCount(Animation.INFINITE);
    //anim.Duration(700);
    //splash.StartAnimation(anim);


    WindowRotationAnimation q = new WindowRotationAnimation();
    Button getStarted = FindViewById<Button>(Resource.Id.myButton);
    getStarted.Click += delegate
    {
        hisname=his.Text;
        hername=her.Text;
        var intent = new Intent(this, typeof(CalculateActivity));
        intent.PutExtra("yourname", hisname);
        intent.PutExtra("GFname",  hername);
        StartActivity(intent);

    };
}

inside your OnCreate of the AnotherActivity.cs you can get these strings like this:

string hisname=Intent.GetStringExtra ("yourname");
string hername=Intent.GetStringExtra ("GFname"); // Seriously :P

This is actually an easy solution if you wanted this one. I would suggest you should research first before you post questions

Happy Coding

Answer 3

将数据从your_first_activity传递到your_next_activity

Intent i = new Intent (Application.Context, typeof(your_next_activity));
i.PutExtra ("item", "item_to_pass");
StartActivity (i);

在your_next_activity

上检索从your_first_activity传递的数据包

string item = Intent.GetStringExtra("item");
