如何在Android中存儲GPS lat和long發送短信？

Question

開發一款徒步應用程序，只需點擊應用程序中的按鈕即可發送人員經緯度座標。當我觸發發送按鈕時，該消息只發送「發送緊急服務到：」nullnull「，意味着它沒有保存lat和long的值與消息。我有完整的gps信號並在清單中具有以下權限。

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /> 

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /> 

<uses-permission android:name="android.permission.INTERNET" /> 

<uses-permission android:name="android.permission.TELEPHONY_MANAGER" /> 

<uses-permission android:name="android.permission.SEND_SMS" /> 

我需要什麼，我下面的代碼更改爲使應用程序成功發送的緯度和經度座標與文本消息。 道歉所有的「吐司」的消息，將它們用於測試目的！

Answer 1

在我看來，當你在public void onLocationChanged(Location Location) {中獲得位置時，只需更新TextView，而不要在SMSManager中使用這些實際值。這裏：smsManager.sendMultipartTextMessage(phoneNumber, null, parts, null, null); 您使用的是持有「發送緊急服務到：」的部分，而不是位置的實際值。

Answer 2

您不更新用於發送短信的字符串中的您的位置詳細信息。嘗試下面的僞代碼。希望能幫助到你！！

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
locationText = "Current Location ="+location.getLatitude() + "," + location.getLongitude(); 
smsManager.sendTextMessage(phoneNo, null, locationText, null, null);
