Change your TextInputLayout to androidx component:

<com.google.android.material.textfield.TextInputLayout
     android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/label">

And add support libraries to your app build.gradle:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
