我正在使用Xamarin,當我點擊一個TextView時,我的模擬器正在執行錯誤,該TextView有一個電話號碼的鏈接。活動需要FLAG_ACTIVITY_NEW_TASK標誌

應用輸出有這樣的輸出:

[MessageQueue-JNI] Exception in MessageQueue callback: handleReceiveCallback 
[MessageQueue-JNI] android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want? 

我在哪裏需要設置的標誌,和我應該把它設置爲?

請問我可以幫到一些忙嗎?

在此先感謝。

編輯

這裏是我的應用程序代碼:

namespace TestTextViewAutoLink 
{ 
    [Activity (Label = "TestTextViewAutoLink", MainLauncher = true)] 
    public class MainActivity : Activity 
    { 
     protected override void OnCreate (Bundle bundle) 
     { 
      base.OnCreate (bundle); 

      TextView textView = new TextView (this.ApplicationContext); 
      textView.AutoLinkMask = Android.Text.Util.MatchOptions.PhoneNumbers; 
      textView.Text = "This is a phone number 0800 32 32 32"; 

      //Linkify.AddLinks(textView, MatchOptions.PhoneNumbers); 

      SetContentView(textView); 
     } 
    } 
} 

其中,在上面的代碼,我應該放在意向標誌?

EDIT2

這裏是我的代碼開始活動,與ActivityFlags.NewTask

namespace TestTextViewAutoLink 
{ 
    [Activity (Label = "TestTextViewAutoLink", MainLauncher = true)] 
    public class MainActivity : Activity 
    { 
     protected override void OnCreate (Bundle bundle) 
     { 
      Intent intent= new Intent(this.ApplicationContext, typeof(AutoLinkActivity)); 
      intent.SetFlags(ActivityFlags.NewTask); 
      StartActivity(intent); 
     } 
    } 
} 

然而,這個錯誤發生現在:

android.util.SuperNotCalledException:活動{TestTextViewAutoLink.TestTextViewAutoLink/testtextviewautolink.MainActivity}沒有通過調用super.onCreate()

我該如何獲得此代碼的工作?

試試這個..

錯誤本身具有意義

Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag 

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
context.startActivity(intent);

你錯過了寫在超類

基地要求的onCreate功能。 OnCreate(bundle);

protected override void OnCreate (Bundle bundle) 
     { 
      base.OnCreate (bundle); 
      Intent intent= new Intent(this.ApplicationContext, typeof(AutoLinkActivity)); 
      intent.SetFlags(ActivityFlags.NewTask); 
      StartActivity(intent); 
     }
