The various other Material design components need special attributes to get implemented. But in this article, the Material design Snackbar is implemented and it doesn’t need the special attributes to get implemented in the application. Have a look at the following image to differentiate between the normal snack bar and the Material design Snackbar in Android. What makes the Material design Snackbar is its design and ease of implementation and customization. Note that we are going to implement this project using the Java language.
Steps to Implement the Material Design Snackbar
Step 1: Create an empty activity Android Studio project
Create an empty activity Android Studio project. Refer to Android | How to Create/Start a New Project in Android Studio to create an Android Studio project. Note that we are going to implement this project using the Java language.
Step 2: Add the required dependency
- Add Material design dependency library to the app-level gradle file.
- To get the app level gradle file goto Project > app > build.gradle.
- And invoke the following dependency.
implementation ‘com.google.android.material:material:1.3.0-alpha03’
- Refer to the following image if unable to get the app level gradle file and invoke the dependency. After invoking the dependency click on the “Sync Now” button at the top right. And make sure that the system should be connected to the network so that it can download the required files.
Step 3: Change the base application theme to the Material Components theme in the styles.xml file
To change the base theme of the application goto app > src > res > styles.xml and invoke the following code.
XML
<resources> <!-- Base application theme. --> <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> </style></resources> |
Refer to the following image if unable to locate and invoke the Material Components theme.
Step 4: Now working with the activity_main.xml file
Invoke the following XML code inside the activity_main.xml or can design on own.
XML
<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" tools:ignore="HardcodedText"> <!--a sample button to show or popup a MDC snackbar--> <Button android:id="@+id/show_snackbar_button" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginStart="32dp" android:layout_marginTop="128dp" android:layout_marginEnd="32dp" android:text="SHOW SNACKBAR" /></LinearLayout> |
Output UI: Run on Emulator
Step 5: Now working with the MainActivity.java
Java
import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;public class MainActivity extends AppCompatActivity { // Button to show the snackbar Button bShowSnackbar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // register the show snackbar button with the appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button); // button click listener to show the snackbar bShowSnackbar.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Snackbar snackbar = Snackbar.make(v, "You have deleted an item", Snackbar.LENGTH_LONG); snackbar.setAction("UNDO", new View.OnClickListener() { @Override public void onClick(View v) { // perform any action when the button on the snackbar is clicked here in this case // it shows a simple toast Toast.makeText(MainActivity.this, "The item has been restored", Toast.LENGTH_SHORT).show(); } }); snackbar.show(); } }); }} |
Kotlin
import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;class MainActivity : AppCompatActivity() { // Button to show the snackbar var bShowSnackbar: Button? = null override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) // register the show snackbar button with the appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button) // button click listener to show the snackbar bShowSnackbar.setOnClickListener(object : OnClickListener() { fun onClick(v: View?) { val snackbar = Snackbar.make(v, "You have deleted an item", Snackbar.LENGTH_LONG) snackbar.setAction("UNDO", object : OnClickListener() { fun onClick(v: View?) { // perform any action when the button on the snackbar is clicked here in this case // it shows a simple toast Toast.makeText( this@MainActivity, "The item has been restored", Toast.LENGTH_SHORT ).show() } }) snackbar.show() } }) }} |
Following output is produced:
More Functionalities of the Material design Snackbar
Functionality 1: Set the duration of the Snackbar manually
- Invoke the following code inside the MainActivity.java.
- In this case, the Snackbar dismiss duration is set for 3 seconds.
Java
import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;public class MainActivity extends AppCompatActivity { // Button to show the snackbar Button bShowSnackbar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // register the show snackbar button with the appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button); // button click listener to show the snackbar bShowSnackbar.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Snackbar snackbar = Snackbar.make(v, "You have deleted an item", Snackbar.LENGTH_LONG); snackbar.setAction("UNDO", new View.OnClickListener() { @Override public void onClick(View v) { // perform any action when the button on the snackbar is clicked here in this case // it shows a simple toast Toast.makeText(MainActivity.this, "The item has been restored", Toast.LENGTH_SHORT).show(); } }); // the duration is in terms of milliseconds in this case its 3 seconds snackbar.setDuration(3000); snackbar.show(); } }); }} |

Functionality 2: Preventing Snackbar overlap, over the FAB (Floating Action Button)
- To prevent the simple overlapping of the Snackbar refer to How To Avoid Snackbar Overlap Floating Action Button in Android?. This method shows the setting of the acnhorPoint to the Floating action button.
- Invoke the following code inside the activity_main.xml.
XML
<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" tools:ignore="HardcodedText"> <!--a sample button to show or popup a MDC snackbar--> <Button android:id="@+id/show_snackbar_button" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginStart="32dp" android:layout_marginTop="128dp" android:layout_marginEnd="32dp" android:text="SHOW SNACKBAR" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <!--a simple floating action button with icon--> <com.google.android.material.floatingactionbutton.FloatingActionButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginEnd="16dp" android:layout_marginBottom="16dp" android:backgroundTint="@color/colorPrimary" android:src="@drawable/ic_add_black_24dp" app:layout_constraintBottom_toTopOf="@+id/snackbar_layout" app:layout_constraintEnd_toEndOf="parent" /> <!--this layout makes the floating action button to raise up whenever the snackbar pops up from bottom--> <androidx.coordinatorlayout.widget.CoordinatorLayout android:id="@+id/snackbar_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentStart="true" android:layout_alignParentBottom="true" app:layout_constraintBottom_toBottomOf="parent" /></androidx.constraintlayout.widget.ConstraintLayout> |
- Now working with the MainActivity.java file to handle the overlapping of the Snackbar.
Java
import androidx.appcompat.app.AppCompatActivity;import androidx.coordinatorlayout.widget.CoordinatorLayout;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;public class MainActivity extends AppCompatActivity { // Button to show the snackbar Button bShowSnackbar; // coordinator layout for snackbar CoordinatorLayout mSnackbarLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // register the show snackbar button with the appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button); // register the coordinator layout with the appropriate ID mSnackbarLayout = findViewById(R.id.snackbar_layout); // button click listener to show the snackbar bShowSnackbar.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // pass the mSnackbarLayout as the view to the "make" function Snackbar snackbar = Snackbar.make(mSnackbarLayout, "You have deleted an item", Snackbar.LENGTH_LONG); snackbar.setAction("UNDO", new View.OnClickListener() { @Override public void onClick(View v) { // perform any action when the button on the snackbar is clicked // here in this case it shows a simple toast Toast.makeText(MainActivity.this, "The item has been restored", Toast.LENGTH_SHORT).show(); } }); // the duration is in terms of milliseconds snackbar.setDuration(3000); snackbar.show(); } }); }} |
Kotlin
import androidx.appcompat.app.AppCompatActivity;import androidx.coordinatorlayout.widget.CoordinatorLayout;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;public class MainActivity extends AppCompatActivity { // Button to show the snackbar Button bShowSnackbar; // coordinator layout for snackbar CoordinatorLayout mSnackbarLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // register the show snackbar button with the appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button); // register the coordinator layout with the appropriate ID mSnackbarLayout = findViewById(R.id.snackbar_layout); // button click listener to show the snackbar bShowSnackbar.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // pass the mSnackbarLayout as the view to the "make" function Snackbar snackbar = Snackbar.make(mSnackbarLayout, "You have deleted an item", Snackbar.LENGTH_LONG); snackbar.setAction("UNDO", new View.OnClickListener() { @Override public void onClick(View v) { // perform any action when the button on the snackbar is clicked // here in this case it shows a simple toast Toast.makeText(MainActivity.this, "The item has been restored", Toast.LENGTH_SHORT).show(); } }); // the duration is in terms of milliseconds snackbar.setDuration(3000); snackbar.show(); } }); }}// This code is written by Ujjwal KUmar Bhardwaj |
Output: Run on Emulator
Functionality 3: Swipe feature for Snackbar to dismiss it
- Invoke the following code inside the activity_main.xml
XML
<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" tools:ignore="HardcodedText"> <!--a sample button to show or popup a MDC snackbar--> <Button android:id="@+id/show_snackbar_button" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginStart="32dp" android:layout_marginTop="128dp" android:layout_marginEnd="32dp" android:text="SHOW SNACKBAR" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <!--this layout makes the floating action button to raise up whenever the snackbar pops up from bottom--> <androidx.coordinatorlayout.widget.CoordinatorLayout android:id="@+id/snackbar_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentStart="true" android:layout_alignParentBottom="true" app:layout_constraintBottom_toBottomOf="parent" /></androidx.constraintlayout.widget.ConstraintLayout> |
- Now working with the MainActivity.java file and while building the Snackbar make sure to pass the coordinator layout for the “make” function.
Java
import androidx.appcompat.app.AppCompatActivity;import androidx.coordinatorlayout.widget.CoordinatorLayout;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;import com.google.android.material.snackbar.Snackbar;public class MainActivity extends AppCompatActivity { // Button to show the snackbar Button bShowSnackbar; // coordinator layout for snackbar CoordinatorLayout mSnackbarLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // register the show snackbar button with the // appropriate ID bShowSnackbar = findViewById(R.id.show_snackbar_button); // register the coordinator layout with the // appropriate ID mSnackbarLayout = findViewById(R.id.snackbar_layout); // button click listener to show the snackbar bShowSnackbar.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { // pass the mSnackbarLayout as the view // to the make function Snackbar snackbar = Snackbar.make(mSnackbarLayout, "You have deleted an item", Snackbar.LENGTH_LONG); snackbar.setAction("UNDO", new View.OnClickListener() { @Override public void onClick(View v) { // perform any action when the button on the snackbar is clicked here in this // case it shows a simple toast Toast.makeText(MainActivity.this, "The item has been restored", Toast.LENGTH_SHORT).show(); } }); // the duration is in terms of milliseconds snackbar.setDuration(3000); snackbar.show(); } }); }} |
