請考慮谷歌地圖gecoding響應的JSON響應。 它由具有五個元素的address_components組成。 通常情況下開發人員會使用它的第一個項目（索引爲0的項目）來查找地址元素，例如ac route和locality和formatted address。但這不是最好的選擇。例如，在這種情況下，第二個項目比其他項目更具描述性地址。有時在同一回覆中有不同地點的同一地址。Google Map API：如何在地理編碼結果中管理不同的「address_components」？
我該如何選擇更好的一個（例如Android中的Google Map API在可用項目中選擇一個，但它並不總是索引爲0的項目，但它在替代項中進行了選擇，我想知道它將如何執行並選擇最好的搭配）？
再說，我也想通過不同address_components的所有元素進行迭代來提取和彙集細條信息，但問題是導致地址不一致的同類型一樣locality元素在不同address_components不同的信息當從不同的address_component項目收集到的信息元素。 作爲示例，在下面的示例中，我們有兩個值شهر جدید اندیشه和Karaj在不同的locality元素中，這兩個元素是兩個不同的城市標籤（在同一鄰域中）。
