onitemclicklistener不能在自定義listvew中工作？

Question

main.xml中

<include layout="@layout/header" /> 

<ListView 
    android:id="@+id/alist" 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:dividerHeight="0dp" 
    android:listSelector="@drawable/list_selector" /> 

<TextView 
    android:id="@+id/android:empty" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/no_reminders" 
    android:visibility="gone" /> 
<TextView 
android:id="@+id/TextView02" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="" 
/>

        .inflate(R.layout.list_remind, parent, false); 

      return retView; 
     } 

    } 

} 

注：我實現了onitemclicklistener自定義listview。但它沒有奏效。

Answer 1

創建ListView控制方式如下，

llv = (ListView) layout.findViewById(R.id.alist); 

之所以這樣做，這是你的列表視圖中不可用你的正常佈局要創建在代碼中動態佈局。
