    text
    copied!<p>I added a <code>textchangelistener</code> to my <code>Edittext</code> in which i check if the text is empty or not. When the text isn't empty and I press on the backspace key, all the text disappears and reappears again. This only occur the first time when backspace is pressed. After that it works like it should.</p> <p>Using Editable s.toString() doesn't solve the issue.</p> <p>What is causing this issue?</p> <p>See the comments in the code for more information: </p> <pre><code>TextWatcher textwatcher = getMandatoryTextWatcher(editText); String text = editText.getText().toString();//At this point String text is not empty. editText.addTextChangedListener(textwatcher); public TextWatcher getMandatoryTextWatcher(final EditText editText) { TextWatcher textwatcher = new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { //To change body of implemented methods use File | Settings | File Templates. } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { //To change body of implemented methods use File | Settings | File Templates. } @Override public void afterTextChanged(Editable s) { try { //The first time this is called(the first softkey backspace press), //text is empty. This causes a weird issue where the character that //was just removed by pressing the backspace, reappears again. //This is only the first time. String text = editText.getText().toString(); if (text.length() &lt;= 0) { editText.setError(errorMandatory); } else if (text.length() &gt; 0) { editText.setError(null); } else { editText.setError(errorMelding); } } catch (NumberFormatException nfe) { editText.setError(errorMeldingTijdensParsen); } } }; return textwatcher; } </code></pre>
