如何刪除List <NameValuePair>的所有元素Android

Question

我想從列表中刪除所有元素。我有這樣的代碼：

private List<NameValuePair> httpQueryPairs; 
    httpQueryPairs = new ArrayList<NameValuePair>(1); 
    httpQueryPairs.add(new BasicNameValuePair("A", foo)); 
    httpQueryPairs.add(new BasicNameValuePair("B", bar)); 
    httpQueryPairs.add(new BasicNameValuePair("C, "Help me i don't know how to delete all elements;)")); 
    httpQueryPairs.removeAll(???);

您是否檢查過arraylist的文檔？ http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html#clear()

使用httpQueryPairs.clear（）
