Prevent enter key on EditText but still show the text as multi-line

I would subclass the widget and override the key event handling in order to block the Enter key:

class MyTextView extends EditText{    ...    @Override    public boolean onKeyDown(int keyCode, KeyEvent event)    {        if (keyCode==KeyEvent.KEYCODE_ENTER)         {            // Just ignore the [Enter] key            return true;        }        // Handle all other keys in the default way        return super.onKeyDown(keyCode, event);    }}

This is a method, where you don't have to override the EditText class. You just catch and replace the newlines with empty strings.

edittext.addTextChangedListener(new TextWatcher() {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) {    /*     * The loop is in reverse for a purpose,     * each replace or delete call on the Editable will cause     * the afterTextChanged method to be called again.     * Hence the return statement after the first removal.     * http://developer.android.com/reference/android/text/TextWatcher.html#afterTextChanged(android.text.Editable)     */    for(int i = s.length()-1; i >= 0; i--){        if(s.charAt(i) == '\n'){            s.delete(i, i + 1);            return;        }    }}});
