Android Snack Bar Tutorial

Here is code to create snackbar in your application. Here I provide simple, custom and with action call back method snack bar in this code tutorial.

       

  

First of all you have to take design support library in your gradle.

compile 'com.android.support:design:25.1.0'

Use the following code.

MainActivity.java

package com.snackbarexample;



import android.graphics.Color;

import android.os.Bundle;

import android.support.design.widget.CoordinatorLayout;

import android.support.design.widget.FloatingActionButton;

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 {



    private CoordinatorLayout coordinatorLayout;

    private Button b_simple, b_action, b_custom;

    private FloatingActionButton fab;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



        coordinatorLayout = (CoordinatorLayout) findViewById(R.id.coordinatorLayout);



        b_simple = (Button) findViewById(R.id.btn_simple);

        b_action = (Button) findViewById(R.id.btn_action);

        b_custom = (Button) findViewById(R.id.btn_custom);



        b_simple.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                Snackbar snackbar = Snackbar

                        .make(coordinatorLayout, "Welcome to devilsparadise9", Snackbar.LENGTH_LONG);



                snackbar.show();

            }

        });



        b_action.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                Snackbar snackbar = Snackbar

                        .make(coordinatorLayout, "Message deleted", Snackbar.LENGTH_LONG)

                        .setAction("UNDO", new View.OnClickListener() {

                            @Override

                            public void onClick(View view) {

                                Snackbar snackbar1 = Snackbar.make(coordinatorLayout, "Message restored!", Snackbar.LENGTH_SHORT);

                                snackbar1.show();

                            }

                        });



                snackbar.show();

            }

        });



        b_custom.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                Snackbar snackbar = Snackbar

                        .make(coordinatorLayout, "No internet connection!", Snackbar.LENGTH_LONG)

                        .setAction("RETRY", new View.OnClickListener() {

                            @Override

                            public void onClick(View view) {

                            }

                        });



                // Changing message text color

                snackbar.setActionTextColor(Color.BLUE);



                // Changing action button text color

                View sbView = snackbar.getView();

                TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);

                textView.setTextColor(Color.WHITE);



                snackbar.show();

            }

        });

    }

}

activity_main.xml

<android.support.design.widget.CoordinatorLayout

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/coordinatorLayout"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity">

    

    <LinearLayout

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:orientation="vertical"

        android:paddingLeft="20dp"

        android:paddingRight="20dp">



        <Button

            android:id="@+id/btn_simple"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:layout_marginTop="30dp"

            android:text="Simple Snackbar" />



        <Button

            android:id="@+id/btn_action"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:layout_marginTop="10dp"

            android:text="Action Callback Snackbar" />



        <Button

            android:id="@+id/btn_custom"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:layout_marginTop="10dp"

            android:text="Custom Snackbar" />



    </LinearLayout>



</android.support.design.widget.CoordinatorLayout>
