Country Code Picker Library

Country Code Picker (CCP) is an android library which provides an easy way to search and select country phone code for the telephone number.

Introduction

  • CCP gives professional touch to your well designed form like login screen, sign up screen, edit profile screen. CCP removes confusion about how to add number and thus make view more understandable. Finally reduces mistakes in user input.

  • Phone number screen without CCP

  • Above view can be transformed by using CCP

  • Tapping on CCP will open a dialog to search and select country

The most recommended usage for CCP is using the default setting so the library will auto check the all the value. To do that, you need to follow the following step:

  1. Add CCP view to layout
  2. Add AppCompatEditText view to layout
  3. register the AppCompatEditText using registerPhoneNumberTextView(AppCompatEditText) we can use TextView instead of AppCompatEditText also.
  4. Let the magic happens ;)

Here the more details step:

  1. Add CCP to layout using the following:

    <com.rilixtech.CountryCodePicker
          android:id="@+id/ccp"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" />
  2. Add AppCompatEditText view to layout:

    <android.support.v7.widget.AppCompatEditText
           android:id="@+id/phone_number_edt"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="phone"
           android:inputType="phone"/>
  3. register the AppCompatEditText with code:

    CountryCodePicker ccp;
    AppCompatEditText edtPhoneNumber;
    
    ...
    
    ccp = (CountryCodePicker) findViewById(R.id.ccp);
    edtPhoneNumber = (AppCompatEditText) findViewById(R.id.phone_number_edt);
    
    ...
    
    ccp.registerPhoneNumberTextView(edtPhoneNumber);
  4. Now look at the magic ;)

you can check validity of phone number using isValid() method.

How to add to your project

  1. Add jitpack.io to your root build.gradle file:

    allprojects {
        repositories {
            jcenter()
            maven { url "https://jitpack.io" }
        }
    }
  2. Add library to your app build.gradle file then sync

    dependencies {
        compile 'com.github.joielechong:countrycodepicker:2.1.5'
    }
  3. Add ccp view to xml layout

    <com.rilixtech.CountryCodePicker
          android:id="@+id/ccp"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" />
  4. Add ccp object in Activity / Fragment

    CountryCodePicker ccp;
    
  5. Bind ccp from layout

    ccp = (CountryCodePicker) findViewById(R.id.ccp);
    
  6. That's it. Run the project and see the results.

Features

If you prefer experience along with only reads, an demo android app is available that demonstrates all the features of this library. Click below button to download from Playstore.

If you just want to read them, here you go:

1. Default country

  • Default country is the country where most of your target audience belong.

  • The default country can be set through xml layout and programmatically as well.

    A. Through xml

    Using country code name

    Add app:ccp_defaultNameCode="US" (replace "US" with your default country name code) to xml layout. Refer List of countries for name codes.

    <com.rilixtech.CountryCodePicker
           android:id="@+id/ccp"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           app:ccp_defaultNameCode="US"  />
    Using phone code
    • add app:ccp_defaultCode="81" (replace 81 with your default country code) to xml layout.Refer List of countries for country codes.

    • Setting default country using phone code is not recommended. There are few cases where more than one countries have same phone code. Say US and Canada have +1. Putting '1' will result in Canada even if you were intended for US. Use app:cpp_defaultNameCode or app:cpp_CountryPreference to overcome issue.

      <com.rilixtech.CountryCodePicker
            android:id="@+id/ccp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:ccp_defaultCode="81" />

      app:ccp_defaultNameCode has higher priority than app:ccp_defaultCode.

    B. Programmatically

    Using country name code

    Use setDefaultCountryUsingNameCode() method.

    Using phone code
    • To set default country programmatically, use setDefaultCountryUsingPhoneCode() method.

    • setDefaultCountryUsingNameCode() or setDefaultCountryUsingPhoneCode() will not set default country as selected country in CCP view. To set default country as selected country in CCP view, call resetToDefaultCountry() method.

    • resetToDefaultCountry() will set default country as selected country in CCP, it can be used at the time of form reset.

    • If you do not specify default country from xml, ID +91 (Indonesia) will be the default country until you update default country programmatically.

2. Choose and set country

Choosing and setting country will update selected country in CCP view.

Choose Country

  1. In order to choose country, click on CCP view.
  2. Then search country by country name or phone code or name code in dialog.
  3. Click on county from list to choose

Set country programmatically

Using country code name
Country in CCP can be using setCountryForNameCode() method.

Using phone code

  • Country in CCP can be using setCountryForCode() method.
  • If specified country code / name code does not match with any country, default country will be set in to CCP.

How to listen change in selection? To get call back when country is changed, you need to add OnCountryChangeListener from code.

ccp.setOnCountryChangeListener(new CountryCodePicker.OnCountryChangeListener() {
   @Override
   public void onCountrySelected(Country selectedCountry) {
       Toast.makeText(getContext(), "Updated " + selectedCountry.getName(), Toast.LENGTH_SHORT).show();
      }
 });

3. Country preference

  • Library has list of countries in alphabetical order. It searches for country in same order. But preferred country/countries have higher priority than rest.
  • There are few cases where more than one countries have same code. For example, Canada, Puerto Rico and US have +1. When lilbrary will try to find country with +1, it will always pick Canada as it's alphabetically first in (1)Canada-(2)Puerto Rico-(3)US.
  • If US is set in country preference, order for search will be (1)US-(2)Canada-(3)Puerto Rico, so it will pick US for +1.
  • Countries of preference will be listed at top in selection dialog. It is helpful when target audience is from a set of countries.
  • Any number of countries can be set in preference.

Set through xml

Add app:ccp_CountryPreference="US,ID,NZ" (replace "US,ID,NZ" with your preference) to xml layout. Refer List of countries for name codes.

<com.rilixtech.CountryCodePicker
          android:id="@+id/ccp"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          app:ccp_CountryPreference="US,ID,NZ"  />

Programmatically

Use setCountryPreference() method.

4. Read selected country

Country's 3 properties (Country name, phone code and name code) can be read individually.

Read selected country phone code

  • To get selected country code as String type and without prefix “+”, use getSelectedCountryCode(); method. => “91”
  • To get selected country code as String type and with prefix “+”, use getSelectedCountryCodeWithPlus(); method. => “+91”
  • To get selected country code as int (Integer) type, use getSelectedCountryCodeAsInt(); method. => 91

Read selected country name

To get selected country’s name, use getSelectedCountryName(); => “Indonesia”

Read selected country name code

To get selected country’s name code, use getSelectedCountryNameCode(); => “ID”

5. Full number support

Full number is combination of country code and carrier number. for example, if country code is 91 and carrier number is 8866667722 then 918866667722 or +918866667722 is the full number.

Register phoneNumberTextView

  • CarrierNumberEditText is the supplementary editText in which carrier number part of full number is entered.
  • A carrierNumberEditText must be registered in order to work with full number.
  • editText can be registered using registerPhoneNumberTextView().

Load full number

  • To load full number, use setFullNumber() method. In this method you need to pass the full number.
  • Prefix “+” is optional for full number so full number can be “91886667722” or “+918866667722”. Both will set same country and carrier number."
  • This will detect country code from full number and set that county to ccp and carrier number ( remaining part of full number other than country code) will be set as text of registered carrier editText.
  • If no valid country code is found in beginning part of full number, default country will be set to CCP and full number will be set as text of registered carrier editText.

Get full number

  • Use getFullNumber(); for full number without “+” prefix.
  • Use getFullNumberWithPlus(); for full number with “+” prefix.
  • A phoneNumberTextView must be registered before any function call of full number like setFullNumber() or getFullNumber().
  • None of the above functions validate the number format of phone.

6. Custom text color

Color of CCP text can be changed according to different background.

Using XML

Add app:ccp_textColor property to xml layout

<com.rilixtech.CountryCodePicker
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:ccp_textColor="@color/custom_color"/>

You can also change the dialog text color with ccp_dialogTextColor attribute. It will be defaulting to your current theme text color.

Programmatically

To set color programmatically, use setTextColor() method.

You can also change the dialog text color with setDialogTextColor() method.

7. Custom background color

CCP background color can be set to any custom color. It will be defaulting to application theme if not set up.

Using XML

Add app:ccp_backgroundColor property to xml layout

<com.rilixtech.CountryCodePicker
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:ccp_backgroundColor="@color/custom_color"/>

Programmatically

To set color programmatically, use setBackgroundColor() method.

8. Custom textSize

  • Text size of CCP content can be changed in order to match rest of the view of form.
  • Everytime when textSize is updated, arrowsize will be updated itself.

Using XML

Add app:ccp_textSize property to xml layout

 <com.rilixtech.CountryCodePicker
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           app:ccp_textSize="26sp"/>

Programmatically

To set textSize programmatically, use setTextSize() method.

9. Custom arrow size

Size if Down arrow of CCP view can be modified in order to match rest of the view of form.

Using XML

Add app:ccp_arrowSize property to xml layout

<com.rilixtech.CountryCodePicker
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:ccp_arrowSize="26sp"/>

Programmatically

To set arrow size programmatically, use setArrowSize() method.

10. Hide country name code

By default, text of CCP contains country's name code. i.e "(US) +1". Country name code can be removed if required.

Using XML

Add app:ccp_hideCodeName property to xml layout

<com.rilixtech.CountryCodePicker
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:ccp_hideNameCode="true"/>

Programmatically

To hide name code programmatically, use hideNameCode() method.

11. Custom master country list

  • If your app expects users from only few countries then you might wish to remove all other countries from selection list.
  • You can remove unnecessary countries by setting your custom master country list.
  • Also it will keep user from selecting irrelevant country.
  • Countries of preference will be listed at top in selection dialog. It is helpful when target audience is from a set of countries.
  • Custom master list will only limit the visibility of irrelevant countries from selection dialog. But all other functions like setCountryForCodeName() or setFullNumber() will consider all the countries.
  • Preferred country list will be a subset of custom master list. If some xyz country is not in custom master list, it won't be added to preferred country list.

Set through xml

Add app:ccp_customMasterCountries="US,ID,NZ,BD,PL,RO,ZW" (replace "US,ID,NZ,BD,PL,RO,ZW" by your own country code names) to xml layout. Refer List of countries for name codes.

<com.rilixtech.CountryCodePicker
       android:id="@+id/ccp"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       app:ccp_customMasterCountries="US,IN,NZ,BD,PL,RO,ZW"  />

Programmatically

  • Use setCustomMasterCountries() method.
  • setCustomMasterCountries(null) will remove custom list and revert to library default list.

12. Custom font

FontFamily of CCP content can be changed in order to match rest of the view of form.

For programmatically and xml

Do the following step first:

  • Step 1: Create a folder named assets under app/src/main/ folder. If you already have app/src/main/assets then jump to next step.
  • Step 2: Put your font's .ttf file in assets folder. For example if file name is myfonts.ttf, it should be app/src/main/assets/myfonts.ttf. Make sure that the extension '.ttf' have contain small letters only. '.TTF' will not work.

Programmatically

  • Step 1: Now prepare typeFace using Typeface typeFace=Typeface.createFromAsset(getContext().getAssets(),"myfonts.ttf");
  • Step 2: Finally apply the type face on ccp ccp.setTypeFace(typeFace); OR ccp.setTypeFace(typeFace,customStyle);

Set through xml

Add app:ccp_textFont="myfonts.ttf" to use the font

<com.rilixtech.CountryCodePicker
      android:id="@+id/ccp"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:ccp_textFont="myfonts.ttf" />

13. National Flag Thumbnail

  • Added flag thumbnail to cpp and selector dialog
  • More thumbnail packs can be added
  • By default flag will be added to the ccp view

Set through xml

Add app:ccp_showFlag="false" to remove flag using xml layout

<com.rilixtech.CountryCodePicker
       android:id="@+id/ccp"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       app:ccp_showFlag="false" />

Programmatically

Use showFlag(false) method to hide the flag.

14. Show Full Country Name

  • Developer might wish to show full country name instead of only code name
  • showFullName will replace name code with full name.
  • If name code was hidden using app:hideNameCode="true" then this will not work.
  • Some country names are real long so go for this option only if your UI has dedicated enough space for it.

Set through xml

Add app:ccp_showFullName="true" to show full nameinstead of name code

<com.rilixtech.CountryCodePicker
       android:id="@+id/ccp"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       app:ccp_showFullName="true"/>

Programmatically

Use showFullName(true) or showFullName(false) method to show / hide the full name.

15. Enable / Disable click

Developer can toggle click listener of CCP

Set through xml

Add app:ccp_clickable="true" to enable click listener.

<com.rilixtech.CountryCodePicker
       android:id="@+id/ccp"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       app:ccp_clickable="false"/>

Programmatically

Use setClickable(true) or setClickable(false) method to enable / disable the click.

16. Hide / Show Phone Code

The phone code can be hide or show if you want. By default the phone code is shown. We don't need to add the attribute to show the phone code.

Set through xml

Add app:ccp_hidePhoneCode="true" to hide the phone code.

<com.rilixtech.CountryCodePicker
       android:id="@+id/ccp"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       app:ccp_hidePhoneCode="true"/>

Programmatically

Use setHidePhoneCode(true) or setHidePhoneCode(false) method to hide / show the phone code.

17. Enable / Disable Auto Formatter

You need to set an EditText for phone number with registerPhoneNumberTextView() to make use of this. Ignore this if you don't. The auto formatter for EditText can be enable/disable by using enablePhoneAutoFormatter attribute. By default, auto formatter is enabled.

Set through xml

Add app:ccp_enablePhoneAutoFormatter="false" to disable.

  ````xml
  <com.rilixtech.CountryCodePicker
         android:id="@+id/ccp"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         app:ccp_enablePhoneAutoFormatter="false"/>
  ````

Programmatically

Use enablePhoneAutoFormatter(true) or enablePhoneAutoFormatter(false) method to enable / disable auto formatter.

To check for it, use isPhoneAutoFormatterEnabled()

18. Enable / Disable Set Country Code By TimeZone

You need to set an EditText for phone number with registerPhoneNumberTextView() to make use of this. Ignore this if you don't. By default, CCP will checking for country code from time zone if no default country code set and no country code is found from device network. The default value is true.

Use ccp_setCountryByTimeZone attribute to change. This attribute is having the least order from defaultNameCode. Here the order CCP use:

  1. defaultNameCode by using ccp_defaultNameCode
  2. Auto detect from device by checking network
  3. time zone from device by using ccp_setCountryByTimeZone
  4. country iso from device locale.
  5. the last default will be defaulting to country code ID (Indonesia).

Set through xml

Add app:ccp_setCountryByTimeZone="false" to disable.

  ````xml
  <com.rilixtech.CountryCodePicker
         android:id="@+id/ccp"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         app:ccp_setCountryByTimeZone="false"/>
  ````

Programmatically

Use enableSetCountryByTimeZone(true) or enableSetCountryByTimeZone(false) method to enable / disable time zone.

To check for it, use isPhoneAutoFormatterEnabled()
