In the below Example, I have created a stylish login page. Here I have design first login activity_main.xml layout here I have added FrameLayout, LinearLayout, TextView, EditText and Button. Now In MainActivity I have used ViewCompat.animate function, For detail see below example it will clearly describe you to Create stylish (animation) login page in android.

Step(1)actvity_main.xml layout-
 

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?colorPrimary"
    android:padding="@dimen/activity_horizontal_margin">

    <LinearLayout
        android:id="@+id/container"
        android:layout_marginTop="100dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:gravity="center"
        android:orientation="vertical"
        tools:ignore="HardcodedText">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="16dp"
            android:alpha="0"
            android:text="This is a Login Activity"
            android:textAppearance="@style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
            android:textColor="@android:color/white"
            android:textSize="22sp"
            tools:alpha="1" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="8dp"
            android:alpha="0"
            android:gravity="center"
            android:text="with some Animations"
            android:textAppearance="@style/TextAppearance.AppCompat.Widget.ActionBar.Subtitle.Inverse"
            android:textSize="20sp"
            tools:alpha="1" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="48dp"
            android:hint="user name"
            android:inputType="text"
            android:scaleX="0"
            android:scaleY="0" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="4dp"
            android:hint="Password"
            android:inputType="textPassword"
            android:scaleX="0"
            android:scaleY="0" />

        <Button
            android:id="@+id/login"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:scaleX="0"
            android:scaleY="0"
            android:text="Login"
            android:theme="@style/button_style" />
    </LinearLayout>

    <ImageView
        android:id="@+id/img_logo"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_gravity="center"
        android:layout_marginTop="12dp"
        android:contentDescription="@string/app_name"
        android:src="@drawable/logo"
        tools:visibility="gone" />
</FrameLayout>

Step(2)-Add button_style theme property in styles.xml file
 

<style name="button_style" parent="Theme.AppCompat">
        <item name="colorControlHighlight">@color/high_light</item>
        <item name="colorButtonNormal">@color/normal</item>
    </style>

Step(3)-MainActivity-
 

public class MainActivity extends AppCompatActivity implements AppBarLayout.OnOffsetChangedListener {

    public static final int STARTUP_DELAY = 300;
    public static final int ANIM_ITEM_DURATION = 1000;
    public static final int EDITTEXT_DELAY = 300;
    public static final int BUTTON_DELAY = 500;
    public static final int VIEW_DELAY = 400;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView logoImageView = (ImageView) findViewById(R.id.img_logo);
        ViewGroup container = (ViewGroup) findViewById(R.id.container);

        ViewCompat.animate(logoImageView)
                .translationY(-250)
                .setStartDelay(STARTUP_DELAY)
                .setDuration(ANIM_ITEM_DURATION).setInterpolator(
                new DecelerateInterpolator(1.2f)).start();

        for (int i = 0; i < container.getChildCount(); i++) {
            View v = container.getChildAt(i);
            ViewPropertyAnimatorCompat viewAnimator;

            if (v instanceof EditText) {
                viewAnimator = ViewCompat.animate(v)
                        .scaleY(1).scaleX(1)
                        .setStartDelay((EDITTEXT_DELAY * i) + 500)
                        .setDuration(500);
            } else if (v instanceof Button) {
                viewAnimator = ViewCompat.animate(v)
                        .scaleY(1).scaleX(1)
                        .setStartDelay((BUTTON_DELAY * i) + 500)
                        .setDuration(500);
            } else {
                viewAnimator = ViewCompat.animate(v)
                        .translationY(50).alpha(1)
                        .setStartDelay((VIEW_DELAY * i) + 500)
                        .setDuration(1000);
            }

            viewAnimator.setInterpolator(new DecelerateInterpolator()).start();
        }
    }


    @Override
    public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
        
    }
}
