<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <LinearLayout
        android:id="@+id/layout_first"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="vertical"
        android:layout_marginTop="27dp">


        <ImageView
            android:layout_width="90dp"
            android:padding="18dp"
            android:layout_height="90dp"
            android:background="@drawable/round_layout"
            android:src="@drawable/key" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="18sp"
            android:layout_marginTop="18dp"
            android:text="@string/wlc_sign_in"/>

    </LinearLayout>

    <LinearLayout
        android:id="@+id/form"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingStart="27dp"
        android:paddingEnd="27dp"
        android:gravity="center"
        android:layout_marginTop="36dp"
        android:orientation="vertical"
        android:layout_below="@+id/layout_first">

        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/email"
            app:startIconDrawable="@drawable/ic_baseline_email_24"
            android:background="@color/white"
            android:layout_marginBottom="27dp">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:background="@color/white"
                android:ems="15"/>

        </com.google.android.material.textfield.TextInputLayout>


        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/password"
            app:startIconDrawable="@drawable/ic_baseline_lock_24"
            android:background="@color/white"
            app:passwordToggleEnabled="true"
            app:passwordToggleTint="@color/primaryColor"
            android:layout_marginBottom="36dp">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPassword"
            android:background="@color/white"
            android:ems="15"/>

    </com.google.android.material.textfield.TextInputLayout>

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="13dp"
            android:text="@string/login_name"/>
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/form"
        android:layout_marginTop="9dp"
        android:layout_centerHorizontal="true">

        <TextView
            android:id="@+id/signin"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/primaryColor"
            android:text="@string/dont_have"/>

    </LinearLayout>

</RelativeLayout>

You will also notice, there’s an ImageView which you can replace with your own project image by simply adding it to the drawable folder:

7. Let’s add the code for Registration as follows:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <LinearLayout
        android:id="@+id/layout_first"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="vertical"
        android:layout_marginTop="18dp">


        <ImageView
            android:layout_width="117dp"
            android:padding="3dp"
            android:layout_height="90dp"
            android:src="@drawable/add" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="18sp"
            android:layout_marginTop="18dp"
            android:text="@string/wlc_sign_up"/>

    </LinearLayout>

    <LinearLayout
        android:id="@+id/form"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingStart="27dp"
        android:paddingEnd="27dp"
        android:gravity="center"
        android:layout_marginTop="36dp"
        android:orientation="vertical"
        android:layout_below="@+id/layout_first">

        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/username"
            app:startIconDrawable="@drawable/ic_baseline_person_24"
            android:background="@color/white"
            android:layout_marginBottom="27dp">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:background="@color/white"
                android:ems="15"/>

        </com.google.android.material.textfield.TextInputLayout>

        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/email"
            app:startIconDrawable="@drawable/ic_baseline_email_24"
            android:background="@color/white"
            android:layout_marginBottom="27dp">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:background="@color/white"
                android:ems="15"/>

        </com.google.android.material.textfield.TextInputLayout>


        <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/password"
            app:startIconDrawable="@drawable/ic_baseline_lock_24"
            android:background="@color/white"
            app:passwordToggleEnabled="true"
            app:passwordToggleTint="@color/primaryColor"
            android:layout_marginBottom="36dp">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textPassword"
                android:background="@color/white"
                android:ems="15"/>

        </com.google.android.material.textfield.TextInputLayout>

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="13dp"
            android:text="@string/login_name"/>
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/form"
        android:layout_marginTop="9dp"
        android:layout_centerHorizontal="true">

        <TextView
            android:id="@+id/signup"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/primaryColor"
            android:text="@string/already_member"/>

    </LinearLayout>

</RelativeLayout>

8. Add the following to strings.xml file

 <string name="login_name">Sign in</string>
    <string name="register_name">Sign up</string>
    <string name="wlc_sign_in">Welcome back, sign in</string>

    <string name="dont_have">Don\'t have an account, Sign up</string>
