How to integrate Android Snackbar?

AndroidMobile DevelopmentApps/Applications

Snackbar is just like Toast in android but it going to interact with action. It going to show the message at the bottom of the screen without any interaction with other views and close automatically after a time-out.

This example demonstrates how to integrate Android Snackbar.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Open build.gradle and add design support library dependency.

apply plugin: 'com.android.application'
android {
   compileSdkVersion 28
   defaultConfig {
      applicationId "com.example.andy.myapplication"
      minSdkVersion 19
      targetSdkVersion 28
      versionCode 1
      versionName "1.0"
      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
   }
   buildTypes {
      release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
   }
}
dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:28.0.0'
   implementation 'com.android.support:design:28.0.0'
   implementation 'com.android.support.constraint:constraint-layout:1.1.3'
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'com.android.support.test:runner:1.0.2'
   androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Step 3 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:id="@+id/layout"
   android:layout_height="match_parent">
   <Button
      android:id="@+id/button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:text="Click here" />
</android.support.design.widget.CoordinatorLayout>

In the above code, we have declare layout id because snackback required parent view. when user click on button it will open snackbar at the bottom.

Step 4 − Add the following code to src/MainActivity.java

import android.annotation.TargetApi;
import android.content.Intent;
import android.graphics.Color;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.support.design.widget.CoordinatorLayout;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   CoordinatorLayout coordinatorLayout;
   @TargetApi(Build.VERSION_CODES.O)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      coordinatorLayout=findViewById(R.id.layout);
      Button button=findViewById(R.id.button);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Snackbar snackbar = Snackbar
            .make(coordinatorLayout, "Welcome to tutorialspoint.com", Snackbar.LENGTH_LONG)
            .setAction("Click", new View.OnClickListener() {
               @Override
               public void onClick(View view) {
                  String url = "http://www.tutorialspoint.com";
                  Intent i = new Intent(Intent.ACTION_VIEW);
                  i.setData(Uri.parse(url));
                  startActivity(i);
               }
            });
            // Changing message text color
            snackbar.setActionTextColor(Color.RED);
            // Changing action button text color
            View sbView = snackbar.getView();
            TextView textView = (TextView) sbView.findViewById(
            android.support.design.R.id.snackbar_text);
            textView.setTextColor(Color.YELLOW);
            snackbar.show();
         }
      });
   }
}

In the above when user click on button, it will show snackbar as shown below -

Snackbar snackbar = Snackbar
.make(coordinatorLayout, "Welcome to tutorialspoint.com", Snackbar.LENGTH_LONG)
.setAction("Click", new View.OnClickListener() {
   @Override
   public void onClick(View view) {
      String url = "http://www.tutorialspoint.com";
      Intent i = new Intent(Intent.ACTION_VIEW);
      i.setData(Uri.parse(url));
      startActivity(i);
   }
});
// Changing message text color
snackbar.setActionTextColor(Color.RED);
// Changing action button text color
View sbView = snackbar.getView();
TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();

In the above code, we have declare snackbar with message as welcome to tutorialspoint.com and a button as "click". when user clicks on click button it will open a tutorialspoint web site in the default browser.

Step 5 − Add the following code to manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.andy.myapplication">
   <uses-permission android:name="android.permission.INTERNET" />
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
      <intent-filter>
          <action android:name="android.intent.action.MAIN" />
          <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
   </application>
</manifest>

In the above code, we have declare internet permission to show web site.

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from an android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −

When you click on a button, it will show snackbar message with click button as shown above.

When you click on "click" button it will open default browser with tutorialspoint.com website.
