TextInputLayout not showing EditText hint before user focus on it

Question

I am using recently released Android Design Support Library to show floating label with EditTexts. But i am facing the problem that the Hint on the EditText is not showing when UI is rendered, but i see the Hint after i focus on the EditTexts.

My Layout is as follows:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    <ScrollView
        android:id="@+id/ScrollView01"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical">

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin">

            <android.support.design.widget.TextInputLayout
                android:id="@+id/name_et_textinputlayout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/activity_vertical_margin">

                <EditText
                    android:id="@+id/FeedBackerNameET"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/feedbackname"
                    android:inputType="textPersonName|textCapWords" />
            </android.support.design.widget.TextInputLayout>

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

                <EditText
                    android:id="@+id/FeedBackerEmailET"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/feedbackemail"
                    android:inputType="textEmailAddress" />

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

            <Spinner
                android:id="@+id/SpinnerFeedbackType"
                android:layout_width="fill_parent"
                android:layout_height="48dp"
                android:layout_marginTop="@dimen/activity_vertical_margin"
                android:entries="@array/feedbacktypelist"
                android:prompt="@string/feedbacktype" />

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

                <EditText
                    android:id="@+id/EditTextFeedbackBody"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/feedbackbody"
                    android:inputType="textMultiLine|textCapSentences"
                    android:lines="5" />

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

            <CheckBox
                android:id="@+id/CheckBoxFeedBackResponse"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/activity_vertical_margin"
                android:text="@string/feedbackresponse" />

            <Button
                android:id="@+id/ButtonSendFeedback"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/activity_vertical_margin"
                android:text="@string/feedbackbutton" />
        </LinearLayout>
    </ScrollView>

</FrameLayout>

<View
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:background="@drawable/toolbar_shadow" />
</FrameLayout>

I have also tried to set hint for the TextInputLayout using method setHint but no luck.

mNameTextInputLayout = (TextInputLayout) v.findViewById(R.id.name_et_textinputlayout);
mNameTextInputLayout.setErrorEnabled(true);
mNameTextInputLayout.setHint(feedBackerNameET.getHint());

mEmailTextInputLayout = (TextInputLayout) v.findViewById(R.id.email_textinputlayout);
mEmailTextInputLayout.setErrorEnabled(true);
mEmailTextInputLayout.setHint(feedBackerEmail.getHint());

mBodyTextInputLayout = (TextInputLayout) v.findViewById(R.id.body_textinputlayout);
mBodyTextInputLayout.setErrorEnabled(true);
mBodyTextInputLayout.setHint(feedBackBody.getHint());

Update:

This is a bug that has been fixed in version 22.2.1 of the library.

Original Answer:

As mentioned by @shkschneider, this is a known bug. Github user @ljubisa987 recently posted a Gist for a workaround:

As noted in the comments, the workaround only works on Android Lollipop and older. It does not work on the Android M Preview.
