Android Snackbar Example

Android Snackbaris an interesting component introduced by Material Design. Snackbars are just like Toast messages except they provide action to interact with. Snackbar will be displayed at the bottom of the screen and can be swiped off in order to dismiss them.

Difference between Toast and Snackbar

  • Toast messages can be customized and printed anywhere on the screen, but a Snackbar can be only shown at the bottom of the screen.
  • A Toast message doesn’t have an action button, but Snackbar may have an action button optionally.
  • Toast message cannot be off until the time limit finish, but Snackbar can be swiped off before the time limit.

You can set how long the message will be shown using this three different values.

  • Snackbar.LENGTH_LONG
  • Snackbar.LENGTH_SHORT
  • Snackbar.LENGTH_INDEFINITE

Let’s Getting into Snackbar Android Example

In Android Studio, Create New Project and fill all the details required to create a new project.

Open build.gradle and add Material Design dependency.

dependencies {
    implementation 'com.google.android.material:material:1.3.0-alpha01'
}

By using material dependency, you can also create components like Recyclerview, Cardview, and snackbar, etc.

Also, setup the application theme as theme.MaterialComponents.

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
</style>

Now, done with the project setup.

Create Simple Android Snackbar

Below is the syntax of a simple snackbar. The make function accepts three parameters. View, display a message, and duration of the message to be displayed.

Snackbar snackbar = Snackbar.make(coordinatorLayout,"This is Simple Snackbar",Snackbar.LENGTH_SHORT);
snackbar.show();

Android Snackbar with Action Callback

You can also mention a callback interaction method using the setAction() method. This allows us to take certain actions when the user interacts with the snackbar.

Snackbar snackbar = Snackbar.make(coordinatorLayout,"Snackbar With Action",Snackbar.LENGTH_SHORT);
snackbar.setAction("UNDO", new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Toast.makeText(getApplicationContext(),"Undo action",Toast.LENGTH_SHORT).show();
    }
});
snackbar.show();

Customizing the Android Snackbar

Snackbar comes with default white color text and #323232 background color. You can override these colors.

Snackbar snackbar = Snackbar.make(coordinatorLayout,"Custom Snackbar",Toast.LENGTH_SHORT);
snackbar.setAction("UNDO", new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Toast.makeText(getApplicationContext(),"Undo action",Toast.LENGTH_SHORT).show();
    }
});

snackbar.setActionTextColor(Color.BLUE);

View snackbarView = snackbar.getView();
TextView snackbarText = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
snackbarText.setTextColor(Color.YELLOW);
snackbar.show();
Custom snackbar with action

Theming snackbars

Snackbars support Material Themingand can be customized in terms of color and typography.

Implementing snackbar theming

Using theme attributes in res/values/styles.xml

<style name="Theme.App" parent="Theme.MaterialComponents.*">
    ...
    <item name="snackbarStyle">@style/Widget.App.Snackbar</item>
    <item name="snackbarButtonStyle">@style/Widget.App.SnackbarButton</item>
</style>

<style name="Widget.App.Snackbar" parent="Widget.MaterialComponents.Snackbar">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Snackbar</item>
    <item name="actionTextColorAlpha">1</item>
  </style>

<style name="Widget.App.SnackbarButton" parent="Widget.MaterialComponents.Button.TextButton.Snackbar">
    <item name="android:textColor">@color/shrine_pink_100</item>
</style>

<style name="ThemeOverlay.App.Snackbar" parent="">
    <item name="colorPrimary">@color/shrine_pink_100</item>
    <item name="colorOnSurface">@color/shrine_pink_900</item>
</style>

or in code (affects only this snackbar):

Snackbar.make(contextView, "Text label", Snackbar.LENGTH_LONG)
    .setAction("Action") {
        // Responds to click on the action
    }
    .setBackgroundTint(resources.getColor(R.color.backgroundTint))
    .setActionTextColor(resources.getColor(R.color.actionTextColor))
    .show()
