動態更新TextView

Question

我想實時更新ListView中的TextView。我有一個套接字連接，我正在偵聽json消息，並且我想解析/標識json以更新現有的5個TextView中的一個名單。

responseid=object.getString("ResponseID"); 
    if(responseid!=null){ 
     for(int j=0;j<myList.size();j++){ 
      //If value match then I want to update the textView of that particular row 
      if(myList.get(j).getName().equals(cid)) { 
        //I successfully get the value of Textview of particular row of Listview now I want to update the this Textview with item variable below. 
       String item = (String) myAdapter.getItem(j).getName(); 
       //Here i want to update Textview 
       myAdapter.notifyDataSetChanged(); 
      } 
     }  
    } 

Answer 1

responseid=object.getString("ResponseID"); 
    if(responseid!=null){ 
     for(int j=0;j<myList.size();j++){ 
      if(myList.get(j).getName().equals(cid)) { 
       String item = (String) myAdapter.getItem(j).getName(); 
       ((TextView)myList.get(j)).setText(item); 
       myAdapter.notifyDataSetChanged(); 
      } 
     }  
    }

通過致電String item = (String) myAdapter.getItem(j).getName();您只需獲取項目名稱值。

設定值轉換爲getItem到定義的類：

YourObjectType item = (YourObjectType)myAdapter.getItem(j); 
item.setName("updatestring"); 
myAdapter.notifyDataSetChanged();
