TextInputLayout PasswordToggle - Handle click event

I have a TextInputLayout with PasswordToggle for one of my password EditText as given below,

<android.support.design.widget.TextInputLayout
                        android:id="@+id/password_input_layout"
                        android:layout_width="match_parent"
                        android:layout_height="@dimen/text_input_height"
                        android:gravity="center"
                   app:passwordToggleDrawable="@drawable/password_visibility"
                        app:passwordToggleEnabled="true">

                        <android.support.v7.widget.AppCompatEditText
                            android:id="@+id/register_password_edittext"
                            android:layout_width="match_parent"                              
                    android:layout_height="@dimen/appcompat_editText_height"
                            android:hint="@string/register_password"
                            android:imeOptions="actionNext"
                            android:inputType="textPassword"/>
</android.support.design.widget.TextInputLayout>

Now I also have TextWatcher implemented for this password EditText to handle validation like this,

 passwordEditText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
            }

            @Override
            public void afterTextChanged(Editable s) {

                // Do validation here.
            }
        });

The problem is, when the user clicks on the eye-icon of the TextInputLayout my TextChangeListener gets triggered for no reason and validation failed block gets executed unnecessarily.

How do I avoid this? How do I handle PasswordToggleIcon click action?

        passwordEditText.addTextChangedListener(new TextWatcher() {
        String textBeforeChange;

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            textBeforeChange = s.toString();
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }

        @Override
        public void afterTextChanged(Editable s) {
            if (!textBeforeChange.equals(s.toString)) {
                // Do validation here.
            } 
        }
    });

If the text hasn't changed then no need to preform validation I suppose? Possibly I am missing the intent of your question. Cheers!
