Phone number formatting an EditText in Android

Question

I am making a simple Address Book app (targeting 4.2) that takes name, address, city, state, zip and phone.

I want to format the phone number input as a phone number

Answer 1

There is a library called PhoneNumberUtils that can help you to cope with phone number conversions and comparisons. For instance, use ...

EditText text = (EditText) findViewById(R.id.editTextId);
PhoneNumberUtils.formatNumber(text.getText().toString())

... to format your number in a standard format.

PhoneNumberUtils.compare(String a, String b);

... helps with fuzzy comparisons. There are lots more. Check out http://developer.android.com/reference/android/telephony/PhoneNumberUtils.html for more.

p.s. setting the the EditText to phone is already a good choice; eventually it might be helpful to add digits e.g. in your layout it looks as ...

<EditText
    android:id="@+id/editTextId"
    android:inputType="phone"
    android:digits="0123456789+" 
/> 

Answer 2

You can use a Regular Expression with pattern matching to extract number from a string.

    String s="";
    Pattern p = Pattern.compile("\\d+");
    Matcher m = p.matcher("(1111)123-456-789"); //editText.getText().toString()                                      
    while (m.find()) {
    s=s+m.group(0);
    }
    System.out.println("............"+s);    

    Output : ............1111123456789

Don't worry. I have make a most of better solution for you. You can see this simple app link below.

private EditText mPasswordField;
public int textLength = 0;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mPasswordField = (EditText) findViewById(R.id.password_field);
    mPasswordField.addTextChangedListener(this);
}

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {


    String text = mPasswordField.getText().toString();
    textLength = mPasswordField.getText().length();

    if (text.endsWith("-") || text.endsWith(" ") || text.endsWith(" "))
        return;

    if (textLength == 1) {
        if (!text.contains("(")) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "(").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());
        }

    } else if (textLength == 5) {

        if (!text.contains(")")) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, ")").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());
        }

    } else if (textLength == 6) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, " ").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());

    } else if (textLength == 10) {
        if (!text.contains("-")) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());
        }
    } else if (textLength == 15) {
        if (text.contains("-")) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());
        }
    }else if (textLength == 18) {
        if (text.contains("-")) {
            mPasswordField.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
            mPasswordField.setSelection(mPasswordField.getText().length());
        }
    } else if (textLength == 20) {
        Intent i = new Intent(MainActivity.this, Activity2.class);
        startActivity(i);

    }



}

@Override
public void afterTextChanged(Editable s) {

}

Not: Don't forget "implement TextWatcher" with your activity class.

Hope you are feeling cool for this solution.

Answer 4

You need to create a class:

public class PhoneTextFormatter implements TextWatcher {

    private final String TAG = this.getClass().getSimpleName();

    private EditText mEditText;

    private String mPattern;

    public PhoneTextFormatter(EditText editText, String pattern) {
        mEditText = editText;
        mPattern = pattern;
        //set max length of string
        int maxLength = pattern.length();
        mEditText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(maxLength)});
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        StringBuilder phone = new StringBuilder(s);

        Log.d(TAG, "join");

        if (count > 0 && !isValid(phone.toString())) {
            for (int i = 0; i < phone.length(); i++) {
                Log.d(TAG, String.format("%s", phone));
                char c = mPattern.charAt(i);

                if ((c != '#') && (c != phone.charAt(i))) {
                    phone.insert(i, c);
                }
            }

            mEditText.setText(phone);
            mEditText.setSelection(mEditText.getText().length());
        }
    }

    @Override
    public void afterTextChanged(Editable s) {

    }

    private boolean isValid(String phone)
    {
        for (int i = 0; i < phone.length(); i++) {
            char c = mPattern.charAt(i);

            if (c == '#') continue;

            if (c != phone.charAt(i)) {
                return false;
            }
        }

        return true;
    }
}

Use this as follows:

phone = view.findViewById(R.id.phone);
phone.addTextChangedListener(new PhoneTextFormatter(phone, "+7 (###) ###-####"));

More like clean:

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {

String text = etyEditText.getText();
    int textlength = etyEditText.getText().length();

    if (text.endsWith("(") ||text.endsWith(")")|| text.endsWith(" ") || text.endsWith("-")  )
                return;

    switch (textlength){
        case 1:
            etyEditText.setEditText(new StringBuilder(text).insert(text.length() - 1, "(").toString());
            etyEditText.setSelection(etyEditText.getText().length());
            break;
        case 5:
            etyEditText.setEditText(new StringBuilder(text).insert(text.length() - 1, ")").toString());
            etyEditText.setSelection(etyEditText.getText().length());
            break;
        case 6:
            etyEditText.setEditText(new StringBuilder(text).insert(text.length() - 1, " ").toString());
            etyEditText.setSelection(etyEditText.getText().length());
            break;
        case 10:
            etyEditText.setEditText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
            etyEditText.setSelection(etyEditText.getText().length());
            break;
    }

}

Answer 6

Simply Use This :

In Java Code :

editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

In XML Code :

<EditText
    android:id="@+id/etPhoneNumber"
    android:inputType="phone"/>

This code work for me. It'll auto format when text changed in edit text.
