How to show material snackbar in android

Android Snackbar is an interesting component introduced by Material Design. Snackbars are just like Toast messages except they provide action to interact with. The 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.
The toast message cannot be off until the time limit is finished, but Snackbar can be swiped off before the time limit.

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

Snackbar.LENGTH_LONG
Snackbar.LENGTH_SHORT
Snackbar.LENGTH_INDEFINITE

Let’s Getting into the Snackbar Android Example

In Android Studio, Create New Project and fill in 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'
}
Code language: JavaScript (javascript)

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

If you want to know more about other material components check the below links.

Android Navigation Drawer

Also, set up 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>
Code language: HTML, XML (xml)

Now, done with the project setup.

Create a Simple Android Snackbar

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

Snackbar snackbar = Snackbar.make(coordinatorLayout,"This is Simple Snackbar",Snackbar.LENGTH_SHORT);
snackbar.show();
Code language: JavaScript (javascript)

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();
Code language: JavaScript (javascript)

Customizing the Android Snackbar

The 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();
Code language: JavaScript (javascript)

Theming snackbars

The snackbar supports Material Theming and can be customized in terms of color and typography.

Implementing snackbar theming

Using these 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>
Code language: HTML, XML (xml)

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()
Code language: JavaScript (javascript)

Conclusion

Thanks for reading this post. The material design has a lot of useful components like Material Button, Cardview, etc. I will write more about material design in my future post.
