Android 5.0 introduced the material design bring the all new design, patterns, widgets and much more. If you not familiar with material design start here.  Here I will talk about SnackBar introduced in Android Material Design. Snack bar is similar android Toast.

Before you can use Snack bar in your Application you need to add following support design dependency

compile 'com.android.support:design:23.1.1'

Snackbar can also contain  Button, which makes it different from Toast.

Snackbar can be shown as follows consisting a message like Toast.

Snackbar.make(view, "CoderzPassion Snackbar", Snackbar.LENGTH_LONG)
                       .setAction("Action", null).show();

 SnackBar with Button

snackbarwithbutton=Snackbar.make(findViewById(android.R.id.content), "Snackbar with Button", Snackbar.LENGTH_LONG)
                       .setAction("Dismiss", customSnackbarClick)
                       .setActionTextColor(Color.RED);
               snackbarwithbutton.show();

Now Final Code

Layout for MainActivity.java

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

<Button
    android:id="@+id/snackbarbutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Snackbar with Button"
    />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:layout_marginRight="20dp"
        android:src="@drawable/ic_done"
        app:fabSize="normal"
        app:layout_anchor="@id/coordinatorLayout"
        app:layout_anchorGravity="bottom|right|end"/>


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