Best Kotlin Android SnackBar Library

Snackbars provide lightweight feedback about an operation. They show a brief message at the bottom of the screen on mobile and lower left on larger devices. Snackbars appear above all other elements on screen and only one can be displayed at a time.

They automatically disappear after a timeout or after user interaction elsewhere on the screen, particularly after interactions that summon a new surface or activity. Snackbars can be swiped off screen.

In this tutorial we will look at the top Snackbar libraries alongside examples of how to use those libraries.

If you prefer to use the default or standard Android SDK SnackBar then we have several examples here.

(a). TSnackbar

Android Snackbar from the Top.

Here is the demo:

Step 1: Install it

To install if first register jitpack in your project-level build.gradle under the allProjects closure:

        maven {
            url 'https://jitpack.io'
        }

Then declare the dependency statement in the app/build.gradle under the dependencies closure:

implementation 'com.github.Redman1037:TSnackBar:V2.0.0'

Sync.

Step 2: Show SnackBar

For example to show a simple snackbar:

TSnackbar.make(findViewById(android.R.id.content),"Hello from TSnackBar.",TSnackbar.LENGTH_LONG).show();

To create a custom callback for example with different colors:

TSnackbar snackbar = TSnackbar.make(findViewById(android.R.id.content), "A Snackbar is a lightweight material design method for providing feedback to a user, while optionally providing an action to the user.", TSnackbar.LENGTH_LONG);
snackbar.setActionTextColor(Color.WHITE);
View snackbarView = snackbar.getView();
snackbarView.setBackgroundColor(Color.parseColor("#CC00CC"));
TextView textView = (TextView) snackbarView.findViewById(com.androidadvance.topsnackbar.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();

Here are more customization examples:

//vectordrawable
TSnackbar snackbar = TSnackbar
        .make(relative_layout_main, "Snacking with VectorDrawable", TSnackbar.LENGTH_LONG);
        snackbar.setActionTextColor(Color.WHITE);
        snackbar.setIconLeft(R.drawable.ic_android_green_24dp, 24);
        View snackbarView = snackbar.getView();
        snackbarView.setBackgroundColor(Color.parseColor("#CC00CC"));
        TextView textView = (TextView) snackbarView.findViewById(com.androidadvance.topsnackbar.R.id.snackbar_text);
        textView.setTextColor(Color.YELLOW);
        snackbar.show();

  //left and right icon
 TSnackbar snackbar = TSnackbar
         .make(relative_layout_main, "Snacking Left & Right", TSnackbar.LENGTH_LONG);
         snackbar.setActionTextColor(Color.WHITE);
         snackbar.setIconLeft(R.mipmap.ic_core, 24); //Size in dp - 24 is great!
         snackbar.setIconRight(R.drawable.ic_android_green_24dp, 48); //Resize to bigger dp
         snackbar.setIconPadding(8);
         snackbar.setMaxWidth(3000); //if you want fullsize on tablets
         View snackbarView = snackbar.getView();
         snackbarView.setBackgroundColor(Color.parseColor("#CC00CC"));
         TextView textView = (TextView) snackbarView.findViewById(com.androidadvance.topsnackbar.R.id.snackbar_text);
         textView.setTextColor(Color.YELLOW);
         snackbar.show();

(b). Light

Light is just the usual Snackbar, but elegant.

below are the demos:

success	Info	warning

Error	Normal	Custom

Step 1: Install it

Start by installing it using the following implementation statement:

dependencies {
    implementation 'io.github.tonnyl:light:1.0.0'
}

Or copy the project from here.

Step 2: Show SnackBar

With Light, each method always returns a Snackbar object which you can then customize. If you call show() the snackbar gets shown.

For example to show a success snackbar:

// Kotlin
import io.github.tonnyl.light.success

success(fab, "Success", Snackbar.LENGTH_SHORT)
    .setAction("Action", {
        Toast.makeText(this@MainActivity, "Hello, Light!", Toast.LENGTH_SHORT).show()
    })
    .show()

To display an info snackbar;

// Kotlin
import io.github.tonnyl.light.info

info(fab, "Info", Snackbar.LENGTH_SHORT).show()

To display a warning snackbar:

// Kotlin
import io.github.tonnyl.light.warning

warning(fab, "Warning", Snackbar.LENGTH_SHORT).show()

To display an error:

// Kotlin
import io.github.tonnyl.light.error

error(fab, "Error", Snackbar.LENGTH_SHORT).show()

To display the default snackbar:

// Kotlin
import io.github.tonnyl.light.normal

normal(fab, "Normal", Snackbar.LENGTH_SHORT).show()

Here's an example of how to create a custom snackbar:

// Kotlin
import io.github.tonnyl.light.make

make(
    fab, // // The view to find a parent from.
    "Awesome Snackbar", // The message to show.
    Snackbar.LENGTH_INDEFINITE, // How long to display the message.
    R.drawable.ic_album_white_24dp, // The left icon of message to show.
    R.color.color_cyan, // The background color of Snackbar.
    android.R.color.white, // The color of text to show.
    R.drawable.ic_done_all_white_24dp,
    R.color.colorAccent) // The left icon of action text.
    .setAction("Done all", {
        // Do whatever you want to do.
        Toast.makeText(this@MainActivity, "Hello, Light!", Toast.LENGTH_SHORT).show()
    })
    .show()
