嘿,我正在使用GPS位置,所以我得到座標,現在我需要的是將這些座標傳遞給我的Web服務並將其存儲到我的數據庫。但我有麻煩以適當的方式存儲它,我認爲我得到的數據對於數據庫來說太大了,這就是爲什麼我要將座標轉換爲十進制格式。當我在代碼中放入DecimaFormat方法時,我遇到了一些錯誤,你能幫助我嗎?轉換爲十進制格式時出錯
這些都是錯誤的:

,這些都是我的代碼(特別是在傳遞過程和DecimalFormat的方法):
class phpconnect extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Mapping2.this);
pDialog.setMessage("Logging in..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args) {
String strLatitude = Long.toString(ILatitude);
String strLongitude = Long.toString(ILongitude);
DecimalFormat df = new DecimalFormat("###.00000");
String frmLat = df.format(strLatitude);
String frmLong = df.format(strLongitude);
// Building parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("latitude", frmLat));
params.add(new BasicNameValuePair("longitude", frmLong));
// 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());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully updated
Intent i = new Intent(getApplicationContext(),
Mapping2.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
}
該錯誤與數據庫調用完全不相關。 – tadman 2013-03-12 20:28:51
是的,我認爲這是因爲在十進制格式,我不知道如何處理它。在我放置代碼之前,它正在工作,但問題是我存儲在我的數據庫中的座標,它變成了999.99999 =,就像那樣。 – MakAdin 2013-03-12 20:34:28
