Getting a phone number in the format XXX-XXX-XXXX from the edittext window in android

Question

Hi I am writing an android in which a user enters a phone number in the edit text box. I want the room was in the form of xxx-xxx-xxxx, which means that the "-" should appear automatically after the user enters the first 3 letters and the other - "

I used EditText anum= (EditText)findViewById(R.id.altnum); anum.addTextChangedListener(new PhoneNumberFormattingTextWatcher()); R.id.altnum); EditText anum= (EditText)findViewById(R.id.altnum); anum.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

but it only enters the format after entering all the numbers. I want to change appears when the user enters data, for example, if he presses 123, please tell me how to do it.

Thank you

Yours faithfully

Answer 1

One of the options - to realize their own InputFilter .

You can use my answers here: click "." repeatedly (confirm ip-address EditText typing) and here: How to install an idea Edittext allow only two numeric values, and two decimal values, eg ##. ## for examples of how to analyze the text in the input time.

If you want dashes to appear automatically, you need to add them to the return of your filter method

Recently, I had a requirement for the same. I tried this using TextWatcher. An exchange here with the hope that someone else might be needed later.

 public class PhoneNumberTextWatcher implements TextWatcher { private static final String TAG = PhoneNumberTextWatcher.class .getSimpleName(); private EditText edTxt; private boolean isDelete; public PhoneNumberTextWatcher(EditText edTxtPhone) { this.edTxt = edTxtPhone; edTxt.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_DEL) { isDelete = true; } return false; } }); } public void onTextChanged(CharSequence s, int start, int before, int count) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void afterTextChanged(Editable s) { if (isDelete) { isDelete = false; return; } String val = s.toString(); String a = ""; String b = ""; String c = ""; if (val != null && val.length() > 0) { val = val.replace("-", ""); if (val.length() >= 3) { a = val.substring(0, 3); } else if (val.length() < 3) { a = val.substring(0, val.length()); } if (val.length() >= 6) { b = val.substring(3, 6); c = val.substring(6, val.length()); } else if (val.length() > 3 && val.length() < 6) { b = val.substring(3, val.length()); } StringBuffer stringBuffer = new StringBuffer(); if (a != null && a.length() > 0) { stringBuffer.append(a); if (a.length() == 3) { stringBuffer.append("-"); } } if (b != null && b.length() > 0) { stringBuffer.append(b); if (b.length() == 3) { stringBuffer.append("-"); } } if (c != null && c.length() > 0) { stringBuffer.append(c); } edTxt.removeTextChangedListener(this); edTxt.setText(stringBuffer.toString()); edTxt.setSelection(edTxt.getText().toString().length()); edTxt.addTextChangedListener(this); } else { edTxt.removeTextChangedListener(this); edTxt.setText(""); edTxt.addTextChangedListener(this); } } } ()> public class PhoneNumberTextWatcher implements TextWatcher { private static final String TAG = PhoneNumberTextWatcher.class .getSimpleName(); private EditText edTxt; private boolean isDelete; public PhoneNumberTextWatcher(EditText edTxtPhone) { this.edTxt = edTxtPhone; edTxt.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_DEL) { isDelete = true; } return false; } }); } public void onTextChanged(CharSequence s, int start, int before, int count) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void afterTextChanged(Editable s) { if (isDelete) { isDelete = false; return; } String val = s.toString(); String a = ""; String b = ""; String c = ""; if (val != null && val.length() > 0) { val = val.replace("-", ""); if (val.length() >= 3) { a = val.substring(0, 3); } else if (val.length() < 3) { a = val.substring(0, val.length()); } if (val.length() >= 6) { b = val.substring(3, 6); c = val.substring(6, val.length()); } else if (val.length() > 3 && val.length() < 6) { b = val.substring(3, val.length()); } StringBuffer stringBuffer = new StringBuffer(); if (a != null && a.length() > 0) { stringBuffer.append(a); if (a.length() == 3) { stringBuffer.append("-"); } } if (b != null && b.length() > 0) { stringBuffer.append(b); if (b.length() == 3) { stringBuffer.append("-"); } } if (c != null && c.length() > 0) { stringBuffer.append(c); } edTxt.removeTextChangedListener(this); edTxt.setText(stringBuffer.toString()); edTxt.setSelection(edTxt.getText().toString().length()); edTxt.addTextChangedListener(this); } else { edTxt.removeTextChangedListener(this); edTxt.setText(""); edTxt.addTextChangedListener(this); } } }

The following code works on adding and removing a script, but the logic is a bit larger:

 public class PhoneNumberTextWatcher implements TextWatcher { private static final String TAG = "PhoneNumberTextWatcher"; private EditText editText; public PhoneNumberTextWatcher(EditText edTxtPhone) { this.editText = edTxtPhone;
