TextInputLayout validation doesn't work.

[khadkarajesh]

It doesn't work with the TextInputLayout validation.
Implementation:
`
Java Code

AwesomeValidation awesomeValidation = new AwesomeValidation(ValidationStyle.TEXT_INPUT_LAYOUT);

awesomeValidation.addValidation(getActivity(), R.id.test_til_email,Patterns.EMAIL_ADDRESS, R.string.error_email);

 awesomeValidation.validate()

*XML

<android.support.design.widget.TextInputLayout
        android:id="@+id/test_til_email"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="enter email" />
    </android.support.design.widget.TextInputLayout>

Could you please provide more details? E.g. layout xml, code, screenshot? Thanks.

[khadkarajesh]

@thyrlian I have updated above. Please have a look above.

Thanks @rajeshkumarkhadka. Could you please tell me what's exactly wrong with the behavior? Any log? Any screenshot? Does the getActivity() return the right activity back? How do you trigger the awesomeValidation.validate() (in some onClickListener)?

I saw this problem too while testing validation with TextInputLayout. getActivity() returns the right activity as it is the Fragment's getActivity() method. Perhaps the problem is using the library from inside a fragment?

As to what are the symptoms of it not working, basically the problem is mAwesomeValidation.validate() is always true despite having added the proper validation so obviously no error message is displayed.

I've tried the following:
On Fragment's onCreateView()

mAwesomeValidation = new AwesomeValidation(ValidationStyle.TEXT_INPUT_LAYOUT);
mAwesomeValidation.addValidation(getActivity(), R.id.usernameWrapper, Patterns.EMAIL_ADDRESS, R.string.err_email);

The Fragment implements OnClickListener and checks whether mAwesomeValidation.validate() == true whenever a button inside the fragment is clicked. The result is always true. Hope that helps!

    @Override
    public void onClick(View v) {
        if (mAwesomeValidation.validate() == true) {
            //It's always executing this code even though the fields have validation issues.
        }
    }

Thanks @obernal for sharing your ideas.

• Actually fragment is not a problem, I use it also in the demo app
• Good to know that the activity passed in is the right one, when not sure, better check with debugger
• I remember now that someone else also had a similar problem - always return true on validate(). That was because of placing the addValidation in the wrong lifecycle call. Please try with some point after onCreateView to see if the problem still exists or not.

@thyrlian I have used fragment's onCreateView method. I didn't find any logs related to the library.

[thyrlian]

Thanks @rajeshkumarkhadka. Would you please try to move the code to another place other than onCreateView (something later)?

[khadkarajesh]

@thyrlian works on onActivityCreated 👍 .

[thyrlian]

@rajeshkumarkhadka cool, glad to hear it's working now. As said before, if the activity is OK, most likely the view to be validated is not available yet at the given lifecycle call.

I am trying to use this library with -

support.design.widget.CoordinatorLayout as Root Layout.

EditText is wrapped by TextInputLayout and there is no fragment implemented.
Its just in One simple activity and its crashing at "validate()" method

Msg monitor shows:
"invoke virtual method 'void android.support.design.widget.TextInputLayout.setError(java.lang.CharSequence)' on a null object reference"

I guess Still not fixed or This library is meant to be used with Fragments only?

@pixma

• From the README's sample code, you'll find below instruction:

// to validate TextInputLayout, pass the TextInputLayout, not the embedded EditText
AwesomeValidation mAwesomeValidation = new AwesomeValidation(TEXT_INPUT_LAYOUT);
mAwesomeValidation.addValidation(activity, R.id.til_email, Patterns.EMAIL_ADDRESS, R.string.err_email);

• From the demo app, this library works perfectly with both activity and fragment.
• According to your log, it seems like the TextInputLayout you passed in is somehow null. Please try to debug about this object.
