如何在Xamarin中的片段之間傳遞數據？

Question

我想在兩個片段之間傳遞數據。我該怎麼做？

此代碼給我一個錯誤：

片段1：

myips = myip.Text; 
mytracks = int.Parse(mytrack.Text); 

intent = new Intent(this.Activity, typeof(TabFragment2)); 

intent.PutExtra("MyData", myip.Text); 
intent.PutExtra("MyData1", mytrack.Text); 

片段2：

string myips = Activity.Intent.GetStringExtra("MyData"); 
int mytracks = int.Parse(Activity.Intent.GetStringExtra("MyData1")); 

Answer 1

intent = new Intent(this.Activity, typeof(TabFragment2));

甲Fragment是一塊AP的可以將放置在活動中，但不應使用此方法打開Fragment。

打開TabFragment2這樣的：

var fragment = new TabFragment2(); 
// Execute a transaction, replacing any existing fragment with this one inside the frame. 
var fragmentTransaction = FragmentManager.BeginTransaction(); 
fragmentTransaction.Replace(Resource.Id.fragment, fragment); 
fragmentTransaction.Commit(); 

有關的信息，你可以閱讀document，這裏是一個example;當您打開Fragment2

：

I want to pass data between two fragments.

當您使用fragmentTransaction.Replace方法來打開你的TabFragment2，你可以傳遞數據這樣

Fragment2 fragment = new Fragment2(); 
Bundle args = new Bundle(); 
args.PutString("param", myip.Text); 
args.PutInt("paramInt", 12); 
fragment.Arguments = args; 

在Fragment2，從Arguments得到的數據：

public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
     View view = LayoutInflater.From(Activity).Inflate(Resource.Layout.fragment2, null); 
     if (Arguments != null) 
     { 
      String mParam1 = Arguments.GetString("param");  
      int mParam2 = Arguments.GetInt("paramInt"); 
     } 
    }
