Android – EditText maximum character limit exceeds callback
•
Android
My idea is to set the error view to EditText when the maximum character limit is reached. Is there a callback for this event, or there may be another way to achieve this effect? Thank you in advance
resolvent:
You can use seterror to edit the text:
editText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void afterTextChanged(Editable s) {
if(s.length() > max)
editText.setError("Error");
}
});
