如何在數據從舊片段傳遞到新片段時獲取數據？

Question

舊的片段。

lst.ItemClick += delegate(object sender, AdapterView.ItemClickEventArgs e) { 
    //var intent = new Intent (this, typeof(TracksByGenres)); 
    //intent.PutStringArrayListExtra ("keys", items); 
    //StartActivity (intent); 
    FragmentTransaction fragmentTx=this.FragmentManager.BeginTransaction(); 
    TracksByGenres fragTrack=new TracksByGenres(); 
    //get our item from listview 
    fragmentTx.Replace(Resource.Id.fragmentContainer,fragTrack,items[e.Position]);  fragmentTx.AddToBackStack(null); 
    fragmentTx.Commit(); 
}; 

新片段（fragTrack）

public async override void OnActivityCreated(Bundle savedInstancesState) 
{ 
    //What can I write? I want to get value from items[e.position] from old fragment 
} 

什麼函數來獲取價值？我有搜索谷歌，但沒有結果，我希望。

修改您的片段添加將接受數據如下

這是你從那裏你把數據第一個片段的方法。

public class FirstFragment :Fragment { 
public string mData; 
public void AddData(string data) { 
mData=data; } 
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
// inflate layout and store in variable //you can use data here // myTextView.Text=mData; } } 

這是第二個片段到您發送數據

public class SecondFragment :Fragment { 
public string mData; 
public void AddData(string data) { 
mData=data; } 
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
// inflate layout and store in variable //you can use data here // myTextView.Text=mData; } } 

現在你可以一邊做如下

SecondFragment aDifferentDetailsFrag = new SecondFragment(); 

aDifferentDetailsFrag.AddData(firstFragment.mData); 
//firstFragment is the instance of FirstFragment from where you are navigating to the secondfragment 
// Replace the fragment that is in the View fragment_container (if applicable). 

fragmentTx.Replace(Resource.Id.fragment_container, aDifferentDetailsFrag);
