你們是不是要觸發項目點擊或全click事件列表點擊？因爲我可以看到你添加了點擊監聽器到ListView而不是列表項目 –

整個列表點擊 –

我想satnam在他的回答中放了什麼是好的，因爲在收到響應之前添加了監聽器，使得更容易測試響應;但如果答覆尚未收到，您將必須處理。還有一件事，它建議的接口函數添加到片段，並調用它的點擊通過實現該接口在活動中添加調用活動的意圖過渡 –

完成這一任務的AsyncTask外。

lvHome.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
       Bardata bardata = result.get(position); 
       Intent intent = new Intent(getActivity(), Individualbar.class); 
       intent.putExtra("bardata", new Gson().toJson(bardata)); 
       startActivity(intent); 
      } 
     }); 
    } else { 
     Toast.makeText(getActivity().getApplicationContext(), "Not able to fetch data from server, please check your internet.", Toast.LENGTH_SHORT).show(); 
    }

，但我想發送結果的意圖...如果我把它放在它之外顯示錯誤與我的結果。 –

然後我怎麼能得到那裏的結果...你可以告訴你？ –

使用全局變量 – Masum

所做的FrameLayout裏可點擊它竊取clickEvent和Kistview是無法呼叫OnItemClick方法。

機器人：可點擊= 「真」

從刪除的FrameLayout上面的行。它應該工作。

我也嘗試過...但它不工作 –

請在onItemClick外面定義AsyncTask。

兄弟如果我想發送城市名稱和一些更多的字符串值到服務器...在哪裏我應該通過... –

試試這個。

public class HomeAdapter extends ArrayAdapter { 

    private List<Bardata> barDataList; 
    private int resource;

沒有rohit ..它也不工作bro ... –

你需要設置監聽每個視圖在適配器試試這個 –

thnk你兄弟你的幫助..我也會這樣.. –

這個答案是一個額外的問題在評論中問道：

如果你正在做一個GET調用，參數添加到URL像/get_call?parameter_1=value_1&parameter_2=value_2。如果是POST或PUT，則可以使用OutputStreamWriter和BufferedWriter將參數放入網址。

例子：

OutputStreamWriter out = null; 
try { 
    out = new OutputStreamWriter(con.getOutputStream()); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 
BufferedWriter bw = null; 
if (out != null) { 
    bw = new BufferedWriter(out); 
} else { 
    // Connection Error 
} 
try { 
    bw.write(parametersAsString); 
    bw.flush(); 
    bw.close(); 
} catch (IOException e1) { 
    e1.printStackTrace(); 
}

可以使用JSONObject把參數和值，並把它們放在parametersAsString更換使用toString()功能

我想發送城市名稱，並根據該城市的名稱得到值...從URL，... –

你可以把城市名稱的參數，但水庫不能從url中檢索ult，而是在'onPostExecute'函數中檢索。您有一個列表作爲結果，因此您可以通過將城市名稱指定爲Fragment類的類變量來完成循環中所需的比較，這可以通過'PostExecute' –
