Trying Get Floating-EditText Children of a ViewGroup

I am trying to get Floating EditText from viewgroup (LinearLayout). Simple EditText Working fine but unable to get with it.

here is my code:

XML code:

<LinearLayout
            android:id="@+id/signup_form"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="64dp"
            android:orientation="vertical">

            <android.support.design.widget.TextInputLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <EditText
                    android:id="@+id/et_name"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/hint_name"
                    android:inputType="textPersonName"
                    android:maxLines="1"
                    android:singleLine="true" />

            </android.support.design.widget.TextInputLayout>

Java code:

for (int i = 0; i < layout.getChildCount(); i++) {

            View v = layout.getChildAt(i);

            if (v instanceof EditText) {

                EditText editText = (EditText) v;

                if (editText.getInputType() == InputType.TYPE_TEXT_VARIATION_PERSON_NAME + 1) {

                    isValid = validateName(et_name);

                    if (!isValid) {

                        break;
                    }

                }

This ( android.support.design.widget.TextInputLayout ) is come between LinearLayout and EditText and i have no idea how to resolve it.

Thanks in advance

TextInputLayout has a method getEditText to retrieve the EditText inside it.

https://developer.android.com/reference/android/support/design/widget/TextInputLayout.html#getEditText()

You should not use getChildAt to retrieve EditText.

Instead:

if (v instanceof TextInputLayout) {
    EditText editText = ((TextInputLayout) v).getEditText();
}

This should work:

if (v instanceof TextInputLayout) {
    EditText editText = (EditText) v.getChildAt(0);

But you should probably add some more checks to be sure you don't run into exceptions.
