將數據從IntentService發送到片段

Question

正如我試圖在這question BroadCastReciever，我試過論據也在我的日誌中傳遞數據沒關係。

Bundle bundle = new Bundle(); 
ArticleDetailFragment fragobj = new ArticleDetailFragment().newInstance2(jsonString); 
fragobj.setArguments(bundle); 
Log.i(TAG, "onHandleIntent: " + bundle); 

但我收到空：我onCreateView（）

public static ArticleDetailFragment newInstance2(String item) { 
     Bundle arguments = new Bundle(); 
     arguments.putString("edttext", item); 
     ArticleDetailFragment fragment = new ArticleDetailFragment(); 
     fragment.setArguments(arguments); 
     return fragment; 
    } 

：

Log.i(TAG, "onCreateViewBundle: " + getArguments().getString("edttext")); 

什麼是做到這一點的最好方法是什麼？

Answer 1

這是因爲您首先使用正確的數據設置正確的片段參數，然後在newInstance2之外重寫它。

Bundle bundle = new Bundle(); 
ArticleDetailFragment fragobj = new ArticleDetailFragment().newInstance2(jsonString); 
fragobj.setArguments(bundle); // <- here you override the arguments that were set inside newInstance with a bundle that has no data in it 
Log.i(TAG, "onHandleIntent: " + bundle); 

應該

ArticleDetailFragment fragobj = ArticleDetailFragment().newInstance2(jsonString); 
Log.i(TAG, "onHandleIntent: " + fragobj.getArguments().getString("edttext")); 

而且對方回答說，除去new關鍵字。他是對的！
