Mono 代码实现返回功能

废话不说直接上干货:

Main.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Button
        android:text="跳转"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button2" />
    <EditText
        android:id="@+id/et_StartTime"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

MainActivity.cs

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

namespace App1
{
    [Activity(Label = "App1", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {
        int count = 1;

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            //无标题栏位
            this.RequestWindowFeature(WindowFeatures.DefaultFeatures);
            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
          
            Button button = FindViewById<Button>(Resource.Id.button2);
            button.Click += button_Click; ;

        }

        void button_Click(object sender, EventArgs e)
        {
            StartActivity(new Intent(this, typeof(Activity1)));
        }
    }
}

layout1.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"

    android:minHeight="25px">
    <Button
        android:text="返回Main"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button1" />
</LinearLayout>

Activity1.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Text.Method;
using Android.Text.Style;
using Android.Views;
using Android.Widget;

namespace App1
{
    [Activity(Label = "Activity1")]
    public class Activity1 : Activity, View.IOnClickListener
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            SetContentView(Resource.Layout.layout1);


            Button button = FindViewById<Button>(Resource.Id.button1);

            button.SetOnClickListener(this);
        }
        public void OnClick(View v)
        {
            Finish();
