EditText setError message does not clear after input

Ok so I only have a EditText field and a button, which when pressed triggers an AsyncTask.

EditText playerName = (EditText)findViewById(R.id.playerEditText);


if(playerName.getText().toString().length() == 0 )
playerName.setError("Player name is required!");
else {
// do async task
}

The problem is that the error message seems to stay up even after when I input valid text to search. Is there a way to remove the error as soon as the EditText is not empty?

In your else bracket, put playerName.setError(null), which will clear the error.

API documentation: "The icon and error message will be reset to null when any key events cause changes to the TextView's text." Though it is not so - and therefore we can regard this as bug.

If you use inputType such as textNoSuggestions, textEmailAddress, textPassword, the error is unset after a character is typed. Nearly as documented but again not exactly - when you delete a character, error stays. It seems, a simple workaround with addTextChangedListener and setError(null) can attain promised behavior.

Besides there are posts about icon losing on Android 4.2. So use with care.

Try this listener:

      playerName.addTextChangedListener(new TextWatcher()
{
public void afterTextChanged(Editable edt){
if( playerName.getText().length()>0)
{
playerName.setError(null);
}
}

If you want to hide the error message one way is you apply onclicklistener on the edit box and then 

editTextName.setOnClickListener(new OnClickListener() {


@Override
public void onClick(View v) {
// TODO Auto-generated method stub
editTextName.setError(Null)
}
});

Below code worked for me

@OnTextChanged(
value = R.id.editTextName,
callback = OnTextChanged.Callback.TEXT_CHANGED)
public void afterInput(CharSequence sequence) {
editTextName.setError(null);
editTextName.setErrorEnabled(false);
}

'

editTextName.setError(null) Will clear the error message.

editTextName.setErrorEnabled(false) Will remove additional padding.

Add a TextWatcher to your EditText and onError, show your error message using et.setError(errorMessage) else you can remove the error message and error icon like below.

// to remove the error message in your EditText
et.setError(null);


// to remove the error icon from EditText.
et.setCompoundDrawables(null, null, null, null);

This code worked for me.

textInputSetting(binding.emailEdt)

fun textInputSetting(view: TextInputLayout) {
view.apply {
this.editText!!.addTextChangedListener {
if (this.editText!!.text.isNotEmpty()) {
this.error = null
this.isErrorEnabled = false
}
}
}
}
