发送SMS消息问题的位置？

Question

快速的问题，我有我的班级设置和我的短信发送，我没有任何错误。我试图发送我的位置作为短信的一部分，作为谷歌地图链接。问题是我的消息正在发送，但位置链接没有通过？但该文件没有错误并且消息传递正常。

任何想法？此外，我还在我的Manifest文件中包含了“访问精确位置”。

类别：

Button btnSendSMS; 
EditText txtPhoneNo; 
EditText txtMessage; 
String message; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_send_sms); 
    btnSendSMS = (Button) findViewById(R.id.btnSendSMS); 
    txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo); 
    txtMessage = (EditText) findViewById(R.id.txtMessage); 


    btnSendSMS.setOnClickListener(new View.OnClickListener() 
    { 
     public void onClick(View v) 
     { 
      String phoneNo = txtPhoneNo.getText().toString(); 
      String message = txtMessage.getText().toString(); 
      displayLocation(); 

      if (phoneNo.length()>0 && message.length()>0) 
       sendSMS(phoneNo, message); 
      else 
       Toast.makeText(getBaseContext(), 
         "Please enter both phone number and message.", 
         Toast.LENGTH_SHORT).show(); 
     } 
    }); 
} 


    private void displayLocation(){ 
     LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 
     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, new LocationListener(){ 
      @Override 
      public void onStatusChanged(String s, int i, Bundle bundle) {} 
      @Override 
      public void onProviderEnabled(String s) {} 
      @Override 
      public void onProviderDisabled(String s) {} 
      @Override 
      public void onLocationChanged(final Location location) {} 
     }); 
     Location myLocation = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER); 
     double longitude = myLocation.getLongitude(); 
     double latitude = myLocation.getLatitude(); 
     message+="https://www.google.co.id/maps/@"+latitude+","+longitude; 
}

其在displayLocation()设置的message变量是您的活性（在代码的顶部声明）的成员变量。所以当你这样做时：

String message = txtMessage.getText().toString(); 
displayLocation(); 

该局部变量message没有修改。

你可以做的是从displayLocation会返回一个字符串，并将其添加到消息：

private String displayLocation() { 
    //... 
    return "https://www.google.co.id/maps/@"+latitude+","+longitude; 
} 

String message = txtMessage.getText().toString() + displayLocation(); 
if (phoneNo.length()>0 && message.length()>0) 
//... 

而且我相信你应该，如果你不使用任何其他地方取出message类的成员变量。
