Format EditText View For Phone Numbers

March 24, 2023 Post a Comment

I have an EditText view and I want it to format the user's input into the phone number format. For example, when the user types in 1234567890, the EditText view should dynamically

Solution 1:

With this code you can make a custom TextWatcher and make any format you desire:

ET.addTextChangedListener(new PhoneNumberFormattingTextWatcher() {
        //we need to know if the user is erasing or inputing some new character
        private boolean backspacingFlag = false;
        //we need to block the :afterTextChanges method to be called again after we just replaced the EditText text
        private boolean editedFlag = false;
        //we need to mark the cursor position and restore it after the edition
        private int cursorComplement;

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            //we store the cursor local relative to the end of the string in the EditText before the edition
            cursorComplement = s.length()-ET.getSelectionStart();
            //we check if the user ir inputing or erasing a character
            if (count > after) {
                backspacingFlag = true;
            } else {
                backspacingFlag = false;
            }
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // nothing to do here =D
        }

        @Override
        public void afterTextChanged(Editable s) {
            String string = s.toString();
            //what matters are the phone digits beneath the mask, so we always work with a raw string with only digits
            String phone = string.replaceAll("[^\\d]", "");

            //if the text was just edited, :afterTextChanged is called another time... so we need to verify the flag of edition
            //if the flag is false, this is a original user-typed entry. so we go on and do some magic
            if (!editedFlag) {

                //we start verifying the worst case, many characters mask need to be added
                //example: 999999999 <- 6+ digits already typed
                // masked: (999) 999-999
                if (phone.length() >= 6 && !backspacingFlag) {
                    //we will edit. next call on this textWatcher will be ignored
                    editedFlag = true;
                    //here is the core. we substring the raw digits and add the mask as convenient
                    String ans = "(" + phone.substring(0, 3) + ") " + phone.substring(3,6) + "-" + phone.substring(6);
                    ET.setText(ans);
                    //we deliver the cursor to its original position relative to the end of the string
                    ET.setSelection(ET.getText().length()-cursorComplement);

                //we end at the most simple case, when just one character mask is needed
                //example: 99999 <- 3+ digits already typed
                // masked: (999) 99
                } else if (phone.length() >= 3 && !backspacingFlag) {
                    editedFlag = true;
                    String ans = "(" +phone.substring(0, 3) + ") " + phone.substring(3);
                    ET.setText(ans);
                    ET.setSelection(ET.getText().length()-cursorComplement);
                }
            // We just edited the field, ignoring this cicle of the watcher and getting ready for the next
            } else {
                editedFlag = false;
            }
        }
    });

Ensure to limit the EditText Lenght in XML to 14 characters

<EditText
    android:id="@+id/editText_phone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="phone"
    android:lines="1"
    android:maxLength="14"/>

Solution 2:

Step 1: Here the code for input field in XML file.

 <EditText
    android:id="@+id/editText_phone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="phone"
    android:lines="1"
    android:maxLength="14"/>

Step 2: Here is the code add into the MainFile.java

 phoneNo = (EditText)findViewById(R.id.editText_phone);
 phoneNo.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

Output: It will give you the number like (123)456-7890

Solution 3:

Try this

The PhoneNumberFormattingTextWatcher() method was not working i tried allot finally i get the solutions

In your xml file paste this

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

in your oncreate method paste this

final EditText editText = (EditText) findViewById(R.id.editTextId);
editText.addTextChangedListener(new TextWatcher()
{
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after)
    {
        // TODO Auto-generated method stub
    }
    @Override
    public void afterTextChanged(Editable s)
    {
        String text = editText.getText().toString();
        int  textLength = editText.getText().length();
        if (text.endsWith("-") || text.endsWith(" ") || text.endsWith(" "))
            return;
        if (textLength == 1) {
            if (!text.contains("("))
            {
                editText.setText(new StringBuilder(text).insert(text.length() - 1, "(").toString());
                editText.setSelection(editText.getText().length());
            }
        }
        else if (textLength == 5)
        {
            if (!text.contains(")"))
            {
                editText.setText(new StringBuilder(text).insert(text.length() - 1, ")").toString());
                editText.setSelection(editText.getText().length());
            }
        }
        else if (textLength == 6)
        {
            editText.setText(new StringBuilder(text).insert(text.length() - 1, " ").toString());
            editText.setSelection(editText.getText().length());
        }
        else if (textLength == 10)
        {
            if (!text.contains("-"))
            {
                editText.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
                editText.setSelection(editText.getText().length());
            }
        }
        else if (textLength == 15)
        {
            if (text.contains("-"))
            {
                editText.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
                editText.setSelection(editText.getText().length());
            }
        }
        else if (textLength == 18)
        {
            if (text.contains("-"))
            {
                editText.setText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
                editText.setSelection(editText.getText().length());
            }
        }
    }
});

Solution 4:

I did a combination of things, i modified my input type to phone, then I used regex to remove all non numeric characters: phonenumber = phonenumber.replaceAll("\D", "");

Solution 5:

In your layout, set the input mode to "phone"

http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputMethod http://developer.android.com/reference/android/text/InputType.html#TYPE_CLASS_PHONE

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="phone" />

If this doesn't quite suit your needs, add a listener to your EditText and format the text manually on each keystroke.

    editText.setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (event.getAction() == KeyEvent.ACTION_UP) {
                // format your EditText here
            }
            return false;
        }
    });
