This example demonstrates how to customize snackBar's layout in Android.

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="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:id="@+id/activity_main"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical"
   android:paddingBottom="@dimen/activity_vertical_margin"
   android:paddingLeft="@dimen/activity_horizontal_margin"
   android:paddingRight="@dimen/activity_horizontal_margin"
   android:paddingTop="@dimen/activity_vertical_margin"
   android:gravity="center"
   tools:context="com.androidmads.ajts.customsnackbar.MainActivity">
   <Button
      android:id="@+id/btn4"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginTop="5dp"
      android:background="@color/colorAccent"
      android:text="Custom Snackbar"
      android:textColor="@android:color/white" />
</LinearLayout>

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

package com.androidmads.ajts.customsnackbar;
import android.graphics.Color;
import android.graphics.Typeface;
import android.os.Build;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.TextView;
import static java.security.AccessController.getContext;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      findViewById(R.id.btn4).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Snackbar mSnackBar = Snackbar.make(v, "Custom Color", Snackbar.LENGTH_LONG);
            TextView mainTextView = (TextView) (mSnackBar.getView()).findViewById(android.support.design.R.id.snackbar_text);
            TextView actionTextView = (TextView) (mSnackBar.getView()).findViewById(android.support.design.R.id.snackbar_action);
            mSnackBar.getView().setBackgroundColor(Color.WHITE);
            Typeface font = Typeface.createFromAsset(getAssets(), "LatoRegular.ttf");
            mainTextView.setTypeface(font);
            actionTextView.setTypeface(font);
            mainTextView.setTextColor(Color.BLACK);
            actionTextView.setTextColor(Color.BLACK);
            mSnackBar.setAction("UNDO", new View.OnClickListener() {
               @Override
               public void onClick(View view) {
                  Snackbar.make(view, "Action!", Snackbar.LENGTH_SHORT).show();
               }
            });
            mSnackBar.show();
         }
      });
   }
}

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

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.androidmads.ajts.customsnackbar">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      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 −
