I have an EditText with a date mask. And when you call the listener, the application crashes.

Arraylist ad for EditText s:

 ArrayList<EditText> ListDocumentExpiry = new ArrayList<>();

In the loop:

 ListBirthDate.get(i).addTextChangedListener(Mask.insert("##.##.####", ListBirthDate.get(i)));

Mask class:

 public abstract class Mask { public static String unmask(String s) { return s.replaceAll("[.]", "").replaceAll("[-]", "") .replaceAll("[/]", "").replaceAll("[(]", "") .replaceAll("[)]", ""); } public static TextWatcher insert(final String mask, final EditText ediTxt) { return new TextWatcher() { boolean isUpdating; String old = ""; public void onTextChanged(CharSequence s, int start, int before,int count) { String str = Mask.unmask(s.toString()); String mascara = ""; if (isUpdating) { old = str; isUpdating = false; return; } int i = 0; for (char m : mask.toCharArray()) { if (m != '#' && str.length() > old.length()) { mascara += m; continue; } try { mascara += str.charAt(i); } catch (Exception e) { break; } i++; } isUpdating = true; ediTxt.setText(mascara); ediTxt.setSelection(mascara.length()); } public void beforeTextChanged(CharSequence s, int start, int count, int after) {} public void afterTextChanged(Editable s) { ediTxt.setError(null); } }; } }

Here is the error itself:

    The setText method calls onTextChanged , which calls setText , which calls onTextChanged , which calls setText , which calls onTextChanged , which calls setText , which calls onTextChanged ... - Vladyslav Matviienko

I do not even know how to explain more clearly ...
ediTxt.setText(mascara); method ediTxt.setText(mascara); calls TextWatcher method, notifying the text manager that the text has changed. Inside the onTextChanged method onTextChanged you change the text again by calling the ediTxt.setText(mascara); method ediTxt.setText(mascara); , which again calls the onTextChanged method. And so on to infinity. More precisely, before the stack overflows.

  • Just the Mask works if the EditText is not in an Array, but in the usual way, for example. Just call thus, editText.addTextChangedListener (Mask.insert ("##. ##. ####", ListBirthDate.get (i))); - DevOma
