I think you should just add one condition over there.
if (address.getPostalCode() != null)
{
sBuilder.append(address.getPostalCode()).append("\n");
}
else
{
// do nothing.
}
Or is it not the thing you want?
Question
I have an app that reverse geocodes latitude & longitude into readable addresses. Here is a sample of the code below:
protected List<Address> doInBackground(Double... params) {
try {
List<Address> addresses = geoCoder.getFromLocation(mylat,
mylong, 1);
StringBuilder sBuilder = new StringBuilder();
if (addresses.size() > 0) {
Address address = addresses.get(0);
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
/**
* Returns a line of the address numbered by the
* given index (starting at 0), or null if no such
* line is present.
*/
sBuilder.append(address.getAddressLine(i)).append(
"\n");
////////////
////////////
// sBuilder.append(address.getLocality()).append("\n");
//sBuilder.append(address.getPostalCode()).append("\n");
}// end for
addressString = sBuilder.toString();
}// end if
return geoCoder.getFromLocation(params[0], params[1], 1);
} catch (IOException e) {
e.printStackTrace();
return null;
}// end catch
}// end doInBackground method
I'd like to modify it so if the PostalCode is null, then print nothing, if it receives a value, display it wit hthe rest of the other details. The issue is I live in a country that do NOT use postal codes, which is why that part of the code is currently commented out. I'd like the app to display postal codes if you're in a country that does use them (most do!) and ignore absence of one if you're in my country or a similar one that do not use postal codes.
Can anyone recommend what change I need to make to allow this? I believe I need to add logic to deal with the appending of string here:
sBuilder.append(address.getPostalCode()).append("\n");
Thanks. :)
