我是java和PHP的新手，有人可以帮助我的数据库只显示0 ...
爪哇代码：
公共类 postData 扩展 Activity {
//Progress Dialog
private ProgressDialog pDialog;
//JSONParser jsonParser = new JSONParser();
//url to update coordinates
private static String url_update_coordinates = "http://www.myurl.com";
//JSON Node names
private static final String TAG_SUCCESS = "Success";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView (R.layout.post_coords);
final Context ctx = this;
//Create button
Button btnUploadCoordinates = (Button) findViewById(R.id.button5);
//Button click event
btnUploadCoordinates.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// updating coordinates on background thread
new UploadCoordinates(ctx).execute();
}
});
}
//Background Async Task to upload coordinates
class UploadCoordinates extends AsyncTask <String, String, String> {
// Before starting background thread Show Progress Dialog
private Context ctx;
public UploadCoordinates(Context ctx) {
this.ctx = ctx;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(postData.this);
pDialog.setMessage("Uploading Coordinates...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
//Creating Coordinates
@Override
protected String doInBackground(String... params) {
JSONArray json = new JSONArray();
MySQLite dbhelper = new MySQLite(ctx);
Cursor data = dbhelper.getlocations();
while(data.moveToNext()) {
int _id = data.getInt(0);
double latitude = data.getDouble(1);
double longitude = data.getDouble(2);
double altitude = data.getDouble(3);
double speed = data.getDouble(4);
double timestamp = data.getDouble(5);
JSONObject jo = new JSONObject();
try{
jo.put("_id", _id);
jo.put("latitude", latitude);
jo.put("longitude", longitude);
jo.put("altitude", altitude);
jo.put("speed", speed);
jo.put("timestamp", timestamp);
} catch(JSONException e) {
}
json.put(jo);
}
String json_data = json.toString();
// Adding the data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("coords", json_data));
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://www.myurl.com");
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
InputStream is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Check log for response
Log.d("Create response", json.toString());
return null;
}
// 检查成功标签
尝试 { int 成功 = json_data.getInt(TAG_SUCCESS);
在这里给我问题 对于 String 类型的方法 getInt(String) 未定义
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), GPSLoggerService.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
//After completion background task Dismiss progress dialog
protected void onPostExecute(String file_url) {
//dismiss the dialog once done
pDialog.dismiss();
}
}
}
php脚本：
<?php
ini_set('error_reporting', E_ALL); ini_set('display_errors','1');
//include dbconnect class
require_once (__DIR__ . '/db_connect.php');
//connecting to db
$db = new DB_CONNECT();
//decode array
$arr = (isset($_POST['coords']));
$decarr = json_decode($arr, true);
$count = count($decarr);
$values = array(); //hold array values so we do one single insert
$update_values = array(); //holds values for the ON DUPLICATE KEY UPDATE
for ($x=0; $x <$count; $x++)
{
$newrec = $decarr[$x];
$_id = $newrec['_id']; $_id = mysql_real_escape_string($_id);
$latitude = $newrec['latitude']; $_id = mysql_real_escape_string($latitude);
$longitude = $newrec['longitude']; $_id = mysql_real_escape_string($longitude);
$timestamp = $newrec['timestamp']; $_id = mysql_real_escape_string($timestamp);
$altitude = $newrec['altitude']; $_id = mysql_real_escape_string($altitude);
$speed = $newrec['speed']; $_id = mysql_real_escape_string($speed);
//create insert array
$values[] = "('".$_id."','".$latitude."','".$longitude."','".$timestamp."','".$altitude."','".$speed."')";
//For the duplicate updates
$update_values[]=
"latitude=VALUES(latitude), longitude=VALUES(longitude), timestamp=VALUES(timestamp), altitude=VALUES(altitude), speed=VALUES(speed)";
}
//insert records
$sql = "INSERT INTO logs(_id, latitude, longitude, timestamp, altitude, speed)
VALUES ".implode(',', $values)." ON DUPLICATE KEY UPDATE ".implode(',',$update_values);
$result = mysql_query($sql);
?>
已经尝试了几个小时，但无法弄清楚问题出在哪里，也许这对你们中的许多人来说是一个愚蠢的问题。
提前感谢您的所有帮助。
问候五
更新 - 不知道我是否应该这样做，但它会更容易，因为所有代码都已经在这里，我的错误是在块引用之间......无法让我的头脑看到问题所在......任何帮助表示赞赏.
