Android Working with Snackbar

build.gradle

compile 'com.android.support:appcompat-v7:25.3.0'

MainActivity.java

public class MainActivity extends AppCompatActivity {

    Button buttonShow;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        buttonShow= (Button) findViewById(R.id.buttonShow);

        buttonShow.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Snackbar.make(v,"Hello World",Snackbar.LENGTH_LONG).show();
            }
        });
    }
}

Snackbar Actions

public void showSnackbar(View view, String message, int duration)
{
    // Create snackbar
    final Snackbar snackbar = Snackbar.make(view, message, duration);

    // Set an action on it, and a handler
    snackbar.setAction("DISMISS", new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            snackbar.dismiss();
        }
    });

    snackbar.show();
}
