[英]Xamarin Android application
今天開始使用Visual Studio中的xamarin開發,到目前為止看起來還不錯,但是我的問題是
如何從單擊按鈕切換到另一個布局(視圖)
當我在登錄頁面上執行以下操作時:
[Activity(Label = "Test", MainLauncher = true, Icon = "@drawable/icon")]
public class Test: Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Afvalwijzer);
EditText Bla1 = FindViewById<EditText>(Resource.Id.Bla1);
Bla1.Hint = "Your text";
EditText Bla2= FindViewById<EditText>(Resource.Id.Bla2);
Bla2.Hint = "Your text";
Button Login = FindViewById<Button>(Resource.Id.BtnLogin);
Login.Click += new EventHandler(Login_Click);
}
void Login_Click(object sender, EventArgs e)
{
EditText Bla1 = FindViewById<EditText>(Resource.Id.Bla1);
EditText Bla2 = FindViewById<EditText>(Resource.Id.Bla2 );
if (!String.IsNullOrEmpty(Bla1.Text) && !String.IsNullOrEmpty(Bla2.Text))
{
AfvalwijzerWS WebS = new AfvalwijzerWS();
var Data = WebS.Authenticate(Bla1.Text, Bla2.Text);
TextView txt = FindViewById<TextView>(Resource.Id.ContentTextView);
if (Data.Count() > 0)
{
SetContentView(Resource.Layout.Index);
}
else
{
MessageBox("No Access !");
}
}
else
{
MessageBox();
}
}
這很好。 但是當我在Index(Layout)上我有相同的代碼是這樣的:
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Index);
Button Contact = FindViewById<Button>(Resource.Id.BtnContact);
Contact.Click += (sender, e) =>
{
SetContentView(Resource.Layout.Contact);
};
}
並且它在布局ofc的xml中引用,但是它不會觸發按鈕事件,有人知道為什么嗎?
您應該開始一個新的活動,而不是設置內容視圖
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Index);
Button Contact = FindViewById<Button>(Resource.Id.BtnContact);
Contact.Click += (sender, e) =>
{
StartActivity(new Intent(this, typeof(/* whatever activity you want */ )));
// e.g.
//StartActivity(new Intent(this, typeof(SplashActivity)));
};
}
