先上图吧！

代码实现其实很简单：

先创建一个Transform类（用来作为为进制转换的工具）

using System;

namespace Conversion  
\{  
class Transform  
\{  
internal string TenToBinary(long value)//将十进制转换为二进制  
\{  
return Convert.ToString(value, 2);  
\}  
internal string TenToEight(long value)//将十进制转换为八进制  
\{  
return Convert.ToString(value, 8);  
\}  
internal string TenToSixteen(long value)//将十进制转换为十六进制  
\{  
return Convert.ToString(value, 16);  
\}  
internal string BinaryToEight(long value)//将二进制转换为八进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value.ToString(), 2), 8);  
\}  
internal string BinaryToTen(long value)//将二进制转换为十进制  
\{  
return Convert.ToInt64(  
value.ToString(), 2).ToString();  
\}  
internal string BinaryToSixteen(long value)//将二进制转换为十六进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value.ToString(), 2), 16);  
\}  
internal string EightToBinary(long value)//将八进制转换为二进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value.ToString(), 8), 2);  
\}  
internal string EightToTen(long value)//将八进制转换为十进制  
\{  
return Convert.ToInt64(  
value.ToString(), 8).ToString();  
\}  
internal string EightToSixteen(long value)//将八进制转换为十六进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value.ToString(), 8), 16);  
\}  
internal string SixteenToBinary(string value)//将十六进制转换为二进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value, 16), 2);  
\}  
internal string SixteenToEight(string value)//将十六进制转换为八进制  
\{  
return Convert.ToString(  
Convert.ToInt64(value, 16), 8);  
\}  
internal string SixteenToTen(string value)//将十六进制转换为十进制  
\{  
return Convert.ToUInt64(value, 16).ToString();  
\}  
\}  
\}

然后在MainActivity中实现功能：

using Android.App;  
using Android.Widget;  
using Android.OS;  
using System;

namespace Conversion  
\{  
\[Activity(Label = "Conversion", MainLauncher = true,Icon ="@drawable/book")\]  
public class MainActivity : Activity  
\{  
Button btnTransform;  
private EditText edtInput,edtOutput;  
RadioButton twoC,eightC,sixteenC, twoC2, eightC2, sixteenC2,tenC,tenC2;  
Spinner spwhere;  
protected override void OnCreate(Bundle savedInstanceState)  
\{  
base.OnCreate(savedInstanceState);  
// Set our view from the "main" layout resource  
SetContentView(Resource.Layout.Main);

edtInput = FindViewById<EditText>(Resource.Id.edtinput);  
edtOutput = FindViewById<EditText>(Resource.Id.edtoutput);  
btnTransform = FindViewById<Button>(Resource.Id.btnTransform);  
twoC = FindViewById<RadioButton>(Resource.Id.twoC);  
eightC = FindViewById<RadioButton>(Resource.Id.eightC);  
sixteenC = FindViewById<RadioButton>(Resource.Id.sixteenC);  
twoC2 = FindViewById<RadioButton>(Resource.Id.twoC2);  
eightC2 = FindViewById<RadioButton>(Resource.Id.eightC2);  
sixteenC2 = FindViewById<RadioButton>(Resource.Id.sixteenC2);  
tenC = FindViewById<RadioButton>(Resource.Id.tenC);  
tenC2 = FindViewById<RadioButton>(Resource.Id.tenC2);  
var comments = FindViewById<EditText>(Resource.Id.edtinput);  
var comments2 = FindViewById<EditText>(Resource.Id.edtoutput);  
//选择条  
  
btnTransform.Click += ButtenTransform;  
  
comments.Click += delegate  
\{  
comments.Text = "";  
\};  
comments2.Click += delegate  
\{  
comments2.Text = "";  
\};  
\}

private void ButtenTransform(object sender,EventArgs args)  
\{  
try  
\{  
Action();//调用Action方法进行转换操作  
\}  
catch (Exception)  
\{  
Toast.MakeText(this, "输入错误请重试，错误", ToastLength.Short).Show();  
\}  
\}  
/// <summary>  
/// 进制转换  
/// </summary>  
private void Action()  
\{  
if (!sixteenC.Checked)  
\{  
long p\_line\_value;  
if (long.TryParse(edtInput.Text, out p\_line\_value))//判断输入的是否是正确的赋值  
\{  
if (tenC.Checked)  
\{  
if (tenC2.Checked)  
\{  
edtOutput.Text = edtInput.Text;  
\}  
else if (twoC2.Checked)  
\{  
edtOutput.Text = new Transform().TenToBinary(long.Parse(edtInput.Text));  
\}  
else if (eightC2.Checked)  
\{  
edtOutput.Text = new Transform().TenToEight(long.Parse(edtInput.Text));  
\}  
else if(sixteenC2.Checked)  
\{  
edtOutput.Text = new Transform().TenToSixteen(long.Parse(edtInput.Text));  
\}  
else  
\{  
Toast.MakeText(this, "输入错误，重试！", ToastLength.Short).Show();  
\}  
\}  
else if (twoC.Checked)  
\{  
if (tenC2.Checked)  
\{  
edtOutput.Text = new Transform().BinaryToTen(long.Parse(edtInput.Text));

\}  
else if (sixteenC2.Checked)  
\{

\}  
else  
\{  
Toast.MakeText(this, "输入错误，重试！", ToastLength.Short).Show();  
\}  
\}  
else if(eightC.Checked)  
\{

\{  
edtOutput.Text = new Transform().EightToTen(long.Parse(edtInput.Text));  
\}  
else if (twoC2.Checked)  
\{  
edtOutput.Text = new Transform().EightToBinary(long.Parse(edtInput.Text));  
\}  
else if (eightC2.Checked)  
\{  
edtOutput.Text = edtInput.Text;  
\}  
else if (sixteenC2.Checked)  
\{  
edtOutput.Text = new Transform().EightToSixteen(long.Parse(edtInput.Text));  
\}  
else  
\{
