嗨，我正在处理GPS位置，因此我正在获取坐标，我现在需要的是将这些坐标传递到我的Web服务并将其存储到我的数据库中。但是我无法以正确的方式存储它，我认为我获取的数据对于数据库来说太大了，这就是为什么我试图将坐标转换为十进制格式的原因。将DecimaFormat方法放入代码中时出现一些错误，您能帮我吗。
这些是错误：

这些是我的代码（特别是关于传递过程和DecimalFormat方法的代码）：
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;
}
}
最佳答案
我在您的代码中发现奇怪的是，ILatitude和ILongitude显然是Long类型的。
纬度和经度最好用double值表示。我认为这里实际上并不需要DecimalFormat，考虑到您将ILatitude设置为两倍，简单的String.valueOf(ILatitude);就足够了。
