This is an Android library project which I built for myself, since I needed to create a login and registration form using phone numbers (uses Google's libphonenumber). An example of how I use my library for registration screen... It contain a country picker using a Spinner, containing flags and names of each country in the list. By default, I set the country prefix number (e.g. "+1" for the US), according to the locale of the device (next to the country Spinner dropdown). Finally, I placed an EditText next to the right of the country code to capture the regional number (phone number without prefix).
Example Usage (assuming this code lives in a Fragment):
CountryMaster cm = CountryMaster.getInstance(context);
ArrayList<Country> countries = cm.getCountries();
String countryIsoCode = cm.getDefaultCountryIso();
Country country = cm.getCountryByIso(countryIsoCode);
Spinner spinner = (Spinner) getActivity().findViewById(R.id.spinner_countries);
CountrySpinnerAdapter adapter = new CountrySpinnerAdapter(context, R.layout.item_spinner_countries, countries);
spinner.setAdapter(adapter);
TextView tvCountryPrefix = (TextView) getActivity().findViewById(R.id.tv_dialprefix);
tvCountryPrefix.setText("+" + country.mDialPrefix);
Let's say the presses the Spinner dropdown and selects a different country:
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
CountryMaster cm = CountryMaster.getInstance(getActivity());
Country country = cm.getCountryByPosition(position);
TextView tvCountryPrefix = (TextView) getActivity().findViewById(R.id.tv_dialprefix);
tvCountryPrefix.setText("+" + country.mDialPrefix);
}
Let's say the user wants to submit the registration data:
public void onClick(View view) {
PhoneNumberUtil util = PhoneNumberUtil.getInstance();
// assuming you only a button in your layout...
boolean isAuthentic = false;
try {
PhoneNumber number = util.parse(mDialPrefix + mPhoneNumber, mCountryIso);
isAuthentic = true;
} catch (NumberParseException e) {
e.printStackTrace();
}
if (isAuthentic) {
// submit code or whatever
}
}
We at Vibin make cool stuff... check out our Photo Notes app and give us feedback on what you think! It's a great way to organize your photos and tag them at the same time!
- Add this library as a dependency: Project -> Properties -> Android -> Add
- You will find a sample layout that you can use to get you going.
- I recommend using a Spinner and SpinnerAdapter to implement your drop-down (just a suggestion!)
