我目前有一个带有 php 和 mysql 的 android 应用程序,但我的问题是,当我的代码传递给 php 并将其存储在 mysql 中时,它总是抛出 0.000000 经度和纬度。
这是我的代码
**
class myLocationlistener implements LocationListener {
@Override
public void onLocationChanged(Location location) {
if (location != null) {
double pLong = location.getLongitude();
double pLat = location.getLatitude();
textLat.setText(Double.toString(pLat));
textLong.setText(Double.toString(pLong));
}
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
class CreateNewProduct extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Sample.this);
pDialog.setMessage("Sending Location");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
String latitude = textLong.getText().toString();
String longitude = textLat.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("latitude", latitude));
params.add(new BasicNameValuePair("longitude", longitude));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), Echos.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
**
这是针对 php
**
if ($_POST['latitude'] && $_POST['longitude'] != null) {
$db_connect = mysql_connect($db_host, $db_user, $db_password) or die(mysql_error());
$db = mysql_select_db($db_name);
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
// mysql inserting a new row
$result = mysql_query("INSERT INTO gpslocation(latitude, longitude) VALUES('latitude', 'longitude')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Product successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}

如果有人对此有所了解,请在这里回答,或者告诉我我是否误导了我的问题。
