我试图在我的第一个应用程序中进行简单的签到。我可以使用正确的长/ lat获取Toast消息，但我希望能够通过电子邮件发送它。我目前从EditText和一个微调器获取我的所有信息，但是这个让我难过。任何帮助表示赞赏。
字符串＆＃39;消息＆＃39;本质上是发送的。我希望它有可能存在。

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 + "\n\n\nKX: " + kx + "\n\n\nStatus: " + service + "\n\n\nComment:" +
comment;
sendBtn(message);
成：
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 + "\n\n\nKX: " + kx + "\n\n\nStatus: " + service + "\n\n\nComment:" +
comment + "\n\n\nLocation: " latitude + longitude;
