我的按钮onClick流程在Xamarin Android中不起作用

Question

我的其他buttons正常工作，而此button无效。

这是我的代码段：

 public class RegisterActivity : Activity
{
    EditText txtfullname;
    EditText txtaddress;
    EditText txtusername;
    EditText txtpassword;
    EditText txtconfirmpass;
    Button btncreate;
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetContentView(Resource.Layout.registerPage);

        txtfullname = FindViewById<EditText>(Resource.Id.editTextFullname);
        txtaddress = FindViewById<EditText>(Resource.Id.editTextAddress);
        txtusername = FindViewById<EditText>(Resource.Id.editTextUsername);
        txtpassword = FindViewById<EditText>(Resource.Id.editTextPassword);
        txtconfirmpass = FindViewById<EditText>(Resource.Id.editTextConfirmPassword);
        btncreate = FindViewById<Button>(Resource.Id.buttonRegister);

        btncreate.Click += Btncreate_Click; //this doesn't get process even though I have an onclick of it

    }

首先确保 Resource.Id.buttonRegister 是您按钮的ID

您创建 EventHandler 的时间：

  btncreate = FindViewById （Resource.Id.buttonRegister）;
btncreate.Click + = Btncreate_Click;

私有void Btncreate_Click（对象发送者，EventArgs e）
  {
     //点击按钮时做点什么
  }
