[Xamarin] 簡單使用AlertDialog
2013-07-19
這東西跟Toast 很像,有方便提示的作用
像是Windows 上面的MessageBox 或是 Javascript 的 Alert 會先阻斷使用者並且下一個決定
很簡單我就不贅述,基本上透過 AlertDialog 就可以輕鬆叫起來
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
namespace TestDialog
{
[Activity(Label = "TestDialog", MainLauncher = true, Icon = "@drawable/icon")]
public class Activity1 : Activity
{
int count = 1;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
var btn1 = FindViewById<Button>(Resource.Id.btn1);
btn1.Click += delegate
{
var alertDialog1 = new AlertDialog.Builder(this).Create();
// 設定Title
alertDialog1.SetTitle("警告視窗TITLE");
// 內文
alertDialog1.SetMessage("Hello , 我是內文");
alertDialog1.SetIcon(Resource.Drawable.Icon);
//第一顆按鈕
alertDialog1.SetButton("OK", (sender, args) => Toast.MakeText(this, "OK被按下了", ToastLength.Short).Show());
//第二顆按鈕
alertDialog1.SetButton2("取消", (sender, args) => Toast.MakeText(this, "取消被按下了", ToastLength.Short).Show());
alertDialog1.Show();
};
}
}
}
因為很簡單所以就沒多加解釋了..
