Answer 1

Give valid style for your TextInputLayout( android:theme="@style/Theme.AppCompat")

<android.support.design.widget.TextInputLayout
  android:id="@+id/testingInputLayout"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:theme="@style/Theme.AppCompat">

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

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

You need to add appCompat & support design dependency (if not)

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

In your manifest file add AppCompat theme,

<application
 ...
android:theme="@style/Theme.AppCompat">
