Question

I am new to Mono For Android and im trying to send one typed-text data from one EditText on activity1.cs to a TextView in another activity, but it doesnt work.
Here is the code:

this is the Activity1.cs:

    public string Item;

     protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

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

        // Get our button from the layout resource,
        // and attach an event to it
        Button AddButton = FindViewById<Button>(Resource.Id.AddButton);
        Button ViewButton = FindViewById<Button>(Resource.Id.ViewButton);
        EditText addNewAssignmentField = FindViewById<EditText>(Resource.Id.addNewAssignmentField);


        AddButton.Click += delegate
        {
            if (addNewAssignmentField.Text == "")
            {
                Toast.MakeText(this, "Please Write Assignment To Add", ToastLength.Short).Show();
            }
            else
            {
                Item = addNewAssignmentField.Text;//.ToString();
                Toast.MakeText(this, "Assignment Added!", ToastLength.Short).Show();
                addNewAssignmentField.Text = "";

             ShowMessage(Item); //ignore this

              }


        };

        ViewButton.Click += delegate
        {
            StartActivity(typeof(ViewListActivity));
        };
    }

This is the other activity:

     Activity1 ac1 = new Activity1();

    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);
        // Set our view from the "ListLayout" layout resource
        SetContentView(Resource.Layout.ListLayout);
        Button button1 = FindViewById<Button>(Resource.Id.button1);
        var listItemsTxt = new TextView(this);
        EditText itemsList = FindViewById<EditText>(Resource.Id.itemsList);
        itemsList.Text = ac1.Item;
    }

the EditText on the other activity isnt getting the text from the EditText on the Activity1.cs

Thank You!

You should pass it through intents

In your first activity

Intent intent = new Intent(Activity1.this, Activity2.class);
intent.putStringExtra("edit_text_content", myEditText.getText().toString());
startActivity(intent);

In your second activity’s onCreate

String text = getIntent().getStringExtra("edit_text_content");
myEditText.setText(text);
