如何将地理位置显示为字符串

Question

我想让一个简单的签入作为我的第一个应用程序。我可以得到一个toast消息与正确的长/晚，但我希望能够通过电子邮件发送它。我目前得到我所有的信息从EditText和一个旋转器，但这一个难倒了我。如有任何帮助，不胜感激。

字符串'message'是本质上发送的内容。我希望它在那里是可能的。

Answer 1

我移动了

 editStoreText = (EditText) findViewById(R.id.editstoretext);
        editKxText = (EditText) findViewById(R.id.editkxtext);
        editCommentText = (EditText) findViewById(R.id.editcommenttext);
        String store = editStoreText.getText().toString();
        String kx = editKxText.getText().toString();
        String comment = editCommentText.getText().toString();
        String service = spinner.getSelectedItem().toString();
        String message = "Store Name: " + store + "nnnKX: " + kx  +       "nnnStatus: " + service + "nnnComment:" +
                comment;
        sendBtn(message);

为:

if(gps.canGetLocation()) {
            double latitude = gps.getLatitude();
            double longitude = gps.getLongitude();
            Toast.makeText(getApplicationContext(), "Your Location is - nLat: " + latitude + "nLong: " + longitude, Toast.LENGTH_LONG).show();

        }

然后在我的消息字符串

中简单地调用纬度和经度

String message = "Store Name: " + store + "nnnKX: " + kx  +       "nnnStatus: " + service + "nnnComment:" +
                comment + "nnnLocation: " latitude + longitude;
