Format EditText View For Phone Numbers
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;
}
});
