如何在我的android應用中將Google自動填充功能置於搜索窗口小部件中？

我對android開發非常陌生，我一直在開發一個應用程序，並遵循開發人員文檔。我正在嘗試將Google地方api和自動完成功能整合到我的應用程序中。基本上，我已經集成了我的地圖片段和我的搜索小部件。我一直試圖整合代碼，以提供一個地方名單，每次輸入一個字母。如何在我的android應用中將Google自動填充功能置於搜索窗口小部件中？

我還是很新的Android開發所以在正確的方向指針將是有益的。謝謝！

我仍在試圖弄清楚這一點。我相信我需要一個內容提供者？ – h20poloman 2014-09-21 01:31:17

Windwaker的庫看起來非常適合Java端。如果您想嘗試一個爲Android提供GooglePlaceAutoComplete小部件的庫，您可以查看Sprockets（我是開發人員）。

使用您的Google API密鑰配置庫後，您可以將GooglePlaceAutoComplete元素添加到您的佈局。例如：

<net.sf.sprockets.widget.GooglePlaceAutoComplete 
    android:id="@+id/place" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"/>

然後你就可以得到用戶選擇通過設置OnPlaceClickListener的Place。

public void onPlaceClick(AdapterView<?> parent, Prediction place, int position) { 
    /* do something with the Place */ 
}

爲了這個目的，我實際上創建了一個Java庫。它基本上是Google Places API的封裝，功能齊全。爲了使用該庫，您必須擁有Google Places API密鑰。（instructions）

，您可以收到自動完成預測的，象這樣的庫：

GooglePlaces client = new GooglePlaces("YOUR_API_KEY_HERE"); 
List<Place> places = client.getQueryPredictions(query);

或地名有：

List<Place> places = client.getPlacePrediction(placeName);

確保你沒有在主線程上執行這些！
