[Android]_ch9.7_地名或地址轉成位置

呼叫Geocoder.getFromLocationName(String
locationName, int maxResults)可將使用者輸入的地名/地址（LocationName）轉成List<Address>

Address物件可以呼叫getLatitude()、getLongitude()得到緯經度

參數maxResults用來限定回傳的資料筆數

[Android]_ch5.1_Spinner元件(一)

nSpinner非常類似下拉選單

n建立Spinner元件以及事件處理步驟如下：

n1.在文字檔案內建立字串陣列作為選項 

n2.layout檔案內使用<Spinner>建立

n「android:entries」屬性設定選項

n3.呼叫setOnItemSelectedListener()
註冊，並實作onItemSelected()以回應選項改變
