Snackbar Material Design Components in Android

The Snackbar is a part of the Material Design Components in Android and provides brief feedback about an operation through a message at the bottom of the screen. It can also optionally contain an action.

To use the Snackbar with Material Design Components in Android, follow these steps:

1. Add Dependency:

Ensure you have the Material Design dependency in your build.gradle:

implementation 'com.google.android.material:material:1.4.0'  // Use the latest version

2. Basic Usage:

You can display a basic Snackbar as follows:

Snackbar.make(view, "This is a Snackbar message", Snackbar.LENGTH_LONG).show()

Here:

  • view: A view within the current layout. Typically, this is the root view of the layout (could be a CoordinatorLayout, FrameLayout, etc.)
  • LENGTH_LONG (or LENGTH_SHORT): Determines how long the Snackbar will be displayed.

3. Adding an Action:

To add an action to the Snackbar:

Snackbar.make(view, "Message deleted", Snackbar.LENGTH_LONG)
    .setAction("Undo") {
        // Code to perform when the action is clicked
    }.show()

4. Customizing Appearance:

To customize the appearance, you can modify the Snackbar's view:

val snackbar = Snackbar.make(view, "This is a Snackbar", Snackbar.LENGTH_LONG)
val snackbarView = snackbar.view
snackbarView.setBackgroundColor(ContextCompat.getColor(this, R.color.your_color))
snackbar.show()

5. Handling with CoordinatorLayout:

If your Snackbar is inside a CoordinatorLayout, the Snackbar will coordinate its movement with other views like FloatingActionButton. For instance, if you have a FloatingActionButton in the same CoordinatorLayout, the Snackbar will push it up when it appears and bring it back down when it disappears.

6. Setting Duration:

Apart from LENGTH_SHORT and LENGTH_LONG, you can set custom durations (in milliseconds). However, note that very long durations could be detrimental to user experience.

snackbar.setDuration(5000).show()  // Show for 5 seconds

7. Callbacks:

To listen to the Snackbar's show and dismiss events:

snackbar.addCallback(object : Snackbar.Callback() {
    override fun onShown(sb: Snackbar?) {
        // Snackbar has been shown
    }

    override fun onDismissed(transientBottomBar: Snackbar?, event: Int) {
        // Snackbar has been dismissed
    }
}).show()

Remember that Snackbars are meant for simple feedback messages. If you need to draw more attention or need user input, consider using a dialog or another appropriate UI pattern.

  1. Implementing Snackbar in Android with Material Components:

    • Description: Introduces Snackbar, a Material Design component used for displaying lightweight messages to the user.
    • Example Code (Java):
      Snackbar.make(view, "Snackbar Message", Snackbar.LENGTH_SHORT).show();
      
  2. Customizing Snackbar appearance in Android:

    • Description: Demonstrates how to customize the appearance of a Snackbar, including text color, background color, and elevation.
    • Example Code (Java):
      Snackbar snackbar = Snackbar.make(view, "Customized Snackbar", Snackbar.LENGTH_SHORT);
      snackbar.getView().setBackgroundColor(ContextCompat.getColor(context, R.color.custom_color));
      snackbar.show();
      
  3. Snackbar vs Toast in Material Design Android:

    • Description: Compares Snackbar and Toast in the context of Material Design, highlighting when to use each.
    • Example Code (Java):
      // Use Snackbar for interactive messages
      Snackbar.make(view, "Interactive Message", Snackbar.LENGTH_SHORT).show();
      
      // Use Toast for simple non-interactive messages
      Toast.makeText(context, "Non-Interactive Message", Toast.LENGTH_SHORT).show();
      
  4. Snackbar with action button in Android example code:

    • Description: Adds an action button to the Snackbar to allow users to perform an action.
    • Example Code (Java):
      Snackbar.make(view, "Message with Action", Snackbar.LENGTH_LONG)
              .setAction("Undo", v -> {
                  // Handle action click
              })
              .show();
      
  5. Snackbar theming and styling in Android:

    • Description: Explores theming and styling options for Snackbars to align with the app's design.

    • Example Code (XML/Java):

      <!-- Apply styles in styles.xml -->
      <style name="AppSnackbar" parent="Widget.MaterialComponents.Snackbar">
          <!-- Customize Snackbar styles -->
      </style>
      
      // Apply custom style to the Snackbar
      Snackbar.make(view, "Themed Snackbar", Snackbar.LENGTH_SHORT)
              .setAction("Retry", v -> {
                  // Handle action click
              })
              .setActionTextColor(ContextCompat.getColor(context, R.color.custom_action_color))
              .applyStyle(R.style.AppSnackbar)
              .show();
      
  6. Snackbar with custom layout in Material Design Android:

    • Description: Incorporates a custom layout within a Snackbar to display complex content.
    • Example Code (Java):
      Snackbar snackbar = Snackbar.make(view, "", Snackbar.LENGTH_LONG);
      View customLayout = getLayoutInflater().inflate(R.layout.custom_snackbar_layout, null);
      snackbar.getView().setBackgroundColor(Color.TRANSPARENT);
      Snackbar.SnackbarLayout snackbarLayout = (Snackbar.SnackbarLayout) snackbar.getView();
      snackbarLayout.addView(customLayout, 0);
      snackbar.show();
      
  7. Snackbar duration and behavior customization in Android:

    • Description: Adjusts the duration and behavior of a Snackbar to meet specific requirements.

      // Customize behavior
      Snackbar snackbar = Snackbar.make(view, "Customized Snackbar", Snackbar.LENGTH_SHORT);
      snackbar.setBehavior(new MyCustomBehavior());
      snackbar.show();
      
  8. Snackbar with CoordinatorLayout in Android:

    • Description: Demonstrates using a CoordinatorLayout with Snackbars for better integration and animations.

          <!-- Snackbar container -->
          <com.google.android.material.snackbar.SnackbarLayout
              android:id="@+id/snackbar_container"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>
      </androidx.coordinatorlayout.widget.CoordinatorLayout>
