我想在我的應用程序中使用谷歌API，我插入任何關鍵字，所以它必須autocompete，並給我城市地址

我想使用谷歌API當我輸入關鍵字它必須給我的城市名稱與該關鍵字我想使用這通過使用StartActivityForResult（）這裏是我到目前爲止我的代碼：但我不知道接下來要做什麼，我有API密鑰，我已經用我的清單文件中的密鑰，我只是想完成編碼部分！我想在我的應用程序中使用谷歌API，我插入任何關鍵字，所以它必須autocompete，並給我城市地址

case R.id.linearPlace:{ startActivityForResult(new Intent(this,Location.class),CITY); 

      }break; 
     } 
    } 

    public void onActivityResult(int requestcode,int resultcode,Intent intent){ 
     super.onActivityResult(requestcode,resultcode,intent); 
     String geoName = intent.getStringExtra(""); 
    }

在這裏我把我的代碼，以便在變化的EditText事件簡單的搜索地址

你能否給我提供一個演示代碼，比如我應該如何調用這個URL？我是新的，從來沒有使用谷歌API有史以來 – bipin

好吧，沒問題，但給我一段時間。 –

ohk非常感謝！ – bipin

我想在我的應用程序中使用谷歌API，我插入任何關鍵字，所以它必須autocompete，並給我城市地址
