How to Customize Snackbar in Android

Snackbars are fairly common in the Android app. Almost every app uses a snack bar to display some information about what's going on in the app. You can consider Snackbar as an alternative or the best version of Toasts in Android.

Step 1: Using a normal Snackbar

To use Snackbar in your app, you just have to have the material design dependency in your app. Add Material design dependency to your build.Gradle app-level.

dependencies {
    implementation "com.google.android.material:$latest_version"
}

And then you can use the snack bar just like toast. For example:

Snackbar.make(view, "Show some message here", Snackbar.LENGTH_SHORT).show()

Step 2: Working with the MainActivity.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.application.snackbarapp.MainActivity">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="show snackbar" />

    </RelativeLayout>

</android.support.design.widget.CoordinatorLayout>

Step 3: Creating a custom layout for a snack bar

Under Layout, the folder creates a layout for the snack bar that must be inflated when creating a snack bar under the mainactivity.java file.

import android.graphics.Color;
import android.support.design.widget.CoordinatorLayout;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    private CoordinatorLayout coordinatorLayout;
    private Button button;

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

        coordinatorLayout = findViewById(R.id.coordinatorLayout);
        button = findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showSnackbar();
            }
        });
    }

    public void showSnackbar() {
        Snackbar snackbar = Snackbar.make(coordinatorLayout, "Marked as Read", Snackbar.LENGTH_INDEFINITE)
                .setAction("UNDO", new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Snackbar snackbar1 = Snackbar.make(coordinatorLayout, "Undo successful", Snackbar.LENGTH_SHORT);
                        snackbar1.show();
                    }
                })
                .setActionTextColor(Color.RED);

        snackbar.show();
    }
}
