This example demonstrates how to use Material Design components in an Android App.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="https://schemas.android.com/apk/res/android"
   xmlns:app="https://schemas.android.com/apk/res-auto"
   xmlns:tools="https://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:background="#F95E5E"
   android:orientation="vertical"
   android:paddingTop="80dp"
   tools:context=".LoginActivity">
   <ImageView
      android:id="@+id/loginLogo"
      android:layout_width="240dp"
      android:layout_height="222dp"
      android:layout_gravity="center"
      android:contentDescription="@string/login_logo"
      android:paddingStart="8dp"
      android:paddingLeft="250dp"
      android:paddingTop="50dp"
      android:paddingEnd="8dp"
      android:src="@drawable/read_my_blog" />
   <EditText
      android:id="@+id/emailText"
      android:layout_width="350dp"
      android:layout_height="60dp"
      android:ems="10"
      android:autofillHints="@string/email_hint"
      android:hint="@string/email_hint"
      android:textColor="#FFFF"
      android:layout_gravity="center"
      android:layout_marginTop="20dp"
      android:layout_marginBottom="10dp"/>
   <EditText
      android:id="@+id/pwdText"
      android:layout_width="350dp"
      android:layout_height="60dp"
      android:layout_gravity="center"
      android:textColor="#FFFF"
      android:layout_marginBottom="25dp"
      android:ems="10"
      android:hint="@string/pass_hint"
      android:inputType="textPassword"/>
   <Button
      android:id="@+id/buttonLogin"
      android:layout_width="260dp"
      android:layout_height="60dp"
      android:layout_gravity="center"
      android:backgroundTint="@color/colorPrimary"
      android:text="@string/login_btn_txt"
      android:textColor="@android:color/white"
      android:layout_marginBottom="20dp"/>
   <ProgressBar
      android:id="@+id/loginProgress"
      style="?android:attr/progressBarStyleHorizontal"
      android:layout_width="400dp"
      android:layout_height="20dp"
      android:layout_gravity="center"
      android:visibility="invisible"
      android:indeterminate="true"
      android:layout_marginBottom="30dp" />
   <Button
      android:id="@+id/buttonRegister"
      android:layout_width="260dp"
      android:layout_height="60dp"
      android:layout_gravity="center"
      android:backgroundTint="@android:color/white"
      android:text="@string/login_reg_btn_txt"
      android:textColor="@color/colorPrimary" />
</LinearLayout>

Step 3 − Add the following code to src/MainActivity.java

package com.app.sample;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
   }
}

Step 4 − Add the following code to the app module dependency

apply plugin: 'com.android.application'
android {
   compileSdkVersion 28
   defaultConfig {
      applicationId "com.app.sample"
      minSdkVersion 21
      targetSdkVersion 28
      versionCode 1
      versionName "1.0"
      testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
   }
   buildTypes {
      release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
      }
   }
}
dependencies {
   ///
   implementation "com.google.android.material:material:1.1.0-alpha02"
}

Step 4 − Add the following code to Manifests/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android" package="com.app.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from the android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
