# MaskedEditTextWatcher
Custom TextWatcher for EditText to mask phone number on-the-fly even with automatic country mask detection
## How to use
### Manual list of masks
```java
//Instantiate your EditText
EditText phoneTextField = (EditText) findViewById(R.id.phoneTextField);
//Create text watcher
MaskedEditTextWatcher simpleListener = new MaskedEditTextWatcher(phoneTextField, new MaskedEditTextWatcherDelegate() {
@Override
public String maskForCountryCode(String text) {
//Here you receive just entered text
//and you should return the mask or null
if (text.equals("1")) {
return "+1 ###-###-####";
} else if (text.equals("7")) {
return "+7 (###) ###-##-##";
} else if (text.equals("44")) {
return "+44 (##) ###-####";
} else if (text.equals("64")) {
return "+64 ## # (###) ##-##";
}
return null;
}
});
//Add the textWatcher to your text field
phoneTextField.addTextChangedListener(simpleListener);
```
### Get mask from google phone library
First of all add the following line to your app module gradle file to install the google phone library
```
compile 'com.googlecode.libphonenumber:libphonenumber:7.1.1'
```
Then just implement MaskedEditTextWatcherDelegate using google phone library
```java
//Instantiate your EditText
EditText phoneTextField = (EditText) findViewById(R.id.phoneTextField);
//Create text watcher
MaskedEditTextWatcher glibListener = new MaskedEditTextWatcher(phoneTextField, new MaskedEditTextWatcherDelegate() {
@Override
public String maskForCountryCode(String text) {
//Here you receive just entered text
//and you should return the mask or null
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
//We just should check if entered text is numeric
Double.parseDouble(text);
//Then we should get the region code based on first entered digits
String regionCode = phoneUtil.getRegionCodeForCountryCode(Integer.parseInt(text));
//Then we get an example number for this region
Phonenumber.PhoneNumber exampleNumber = phoneUtil.getExampleNumber(regionCode);
//We should check the number and if it's null then we alse return null
if (exampleNumber == null) return null;
//Here we get country code as digits
int countryCodeForRegion = phoneUtil.getCountryCodeForRegion(regionCode);
//Here we create the string with country code with + symbol
String detectedCountryCode = "+" + countryCodeForRegion;
//Here we create example number but wothout country code
String example = phoneUtil.format(exampleNumber, PhoneNumberUtil.PhoneNumberFormat.NATIONAL);
example = example.replace("8 ", ""); //needed for Russian example number
example = example.replace(detectedCountryCode, "");
//And finally we create full mask with country code
return detectedCountryCode+" "+example.replaceAll("\\d", "#");
} catch (NumberFormatException e) {
//If entered text is not numeric then we shoul return null
return null;
}
}
});
//Add the textWatcher to your text field
phoneTextField.addTextChangedListener(glibListener);
