Mazs's Notes

要實作前請先看前置作業http://cookiesp.pixnet.net/blog/post/77243100

這個程式分了兩個java檔welcome.java跟GoogleMapActivity
所有的文字檔都在value下的string.xml

layout有3個 

welcom.xml是welcome.java的 

main.xml是GoogleMapActivity.java的

alert.xml是GoogleMapActivity裡設定經緯度的AlertDialog的

附上APK檔(只能在android emulator裡用 因為GoogleMap金鑰是只限測試用)  http://dl.dropbox.com/u/23148579/EasyMap.apk 

先看結果

下面是主程式程式碼 welcome很簡單 就是一個imageView按下去會切換到GoogleMapActivity而已 就不貼了

string.xml就是字串而已 也不貼了
