爲什麼你'Concat'舊字符串與新？ 's2 = s2 + ....'，只需設置新的字符串到你的''字符串 –

可能dublicate的http://stackoverflow.com/questions/21073664/auto-refresh-textview幾乎完全相同的代碼。 –

Vishal只是使用：s（n）= jsonValue; –

如果顯示新老數據，你應該在你的代碼中使用的setText代替append方法。這隻在你的更新方法中。我不知道你是一次一行地追加還是全文追加，在第一種情況下，你需要撥打setText作爲第一行，如果是第二種情況，則繼續使用append， setText就好。

如果我沒有錯，你以前也問過同樣的問題。正如我之前告訴你的那樣，你正在用舊信息附加新信息。例如

s2= s2 +"Name : "+json.getString("t2")+"\n"+"Run : "+json.getInt("t2_r")+"/"+json.getInt("t2_w")+"\n"+ 
         "Over : "+json.getInt("t2_o");

那麼你設置的是s2與新的數據一起由舊數據的文本視圖，從而導致中顯示兩個數據。您必須將s2的值設置爲s2=""以確保舊值不會繼續。
