listview點擊多個活動

Question

我有一個問題，我的代碼iv一直試圖解決這個錯誤，但仍然沒有運氣。我想一個新的活動啓動時，在列表視圖中的項目被點擊我找了一段時間發現這個代碼

public void onItemClick(AdapterView<?> parent, View view, 
    int position, long id) { 
    switch(position) 
    { 
    case 0: Intent newActivity = new Intent(this, superleague.class);  
      startActivity(newActivity); 
      break; 
    case 1: Intent newActivity = new Intent(this, youtube.class);  
      startActivity(newActivity); 
      break; 
    case 2: Intent newActivity = new Intent(this, olympiakos.class);  
      startActivity(newActivity); 
      break; 
    case 3: Intent newActivity = new Intent(this, karaiskaki.class);  
      startActivity(newActivity); 
      break; 
    case 4: Intent newActivity = new Intent(this, reservetickets.class);  
      startActivity(newActivity); 
      break; 
    } 
    } 

現在我把這個在我的項目，它是哪裏的問題，但因爲我新的這需要一些時間來解決小事希望你能幫助？

請讓我知道如果我失去了一些東西也感謝 P.S我不能運行這個項目，所以我不能打印日誌CAT

Answer 1

既然你正在擴展ListActivity時，onItemClickListener將無法正常工作。 你必須使用onListItemClickListner然後它將工作。

Answer 2

您正在使用ListActivity，但您的視圖中沒有任何列表。

你應該有一個元素

<ListView 
    android:id="@android:id/list" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" > 
</ListView> 

在你的佈局能夠使用ListActivity。

但它看起來像你已經削減了一些XML，因爲我沒有看到關閉RelativeLayout標記
