How to set a circular FAB button

I am trying to set a circular fab button which on clicked display other options in a circular but I am getting some error on setting the setImageDrawable I am using compile time dependency compile 'com.oguzdev:CircularFloatingActionMenu:1.0.2' my java code is

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.ImageView;
import com.oguzdev.circularfloatingactionmenu.library.FloatingActionMenu;
import com.oguzdev.circularfloatingactionmenu.library.SubActionButton;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

   final FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            SubActionButton.Builder itemBuilder = new SubActionButton.Builder(MainActivity.this);
            ImageView itemIcon = new ImageView(MainActivity.this);
            int id = getResources().getIdentifier("yourpackagename:drawable/" + step-forward, null, null);
            itemIcon.setImageDrawable(R.drawable.button_action);
            SubActionButton button1 = itemBuilder.setContentView(itemIcon).build();

        FloatingActionMenu actionMenu = new FloatingActionMenu.Builder(MainActivity.this)
                .addSubActionView(button1)

                .attachTo(fab)
                .build();}
    });
}

} What changes will i do to make the sub action button work and when I use

 ImageView icon = new ImageView(this);
icon.setImageDrawable( ... );
FloatingActionButton actionButton = new FloatingActionButton.Builder(this)
.setContentView(icon)
.build();`

in place of final FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) {

declaring the fab button i get error in build WHEN i used only one source like this

 ImageView icon = new ImageView(this); // Create an icon
            icon.setImageDrawable(R.drawable.step_forward );
            FloatingActionButton actionButton = new     FloatingActionButton.Builder(this)
                    .setContentView(icon)
                    .build();
            SubActionButton.Builder itemBuilder = new   SubActionButton.Builder(MainActivity.this);
            ImageView itemIcon = new ImageView(MainActivity.this);
            int id = getResources().getIdentifier("yourpackagename:drawable/" + step-forward, null, null);
            itemIcon.setImageDrawable(R.drawable.button_action);
            SubActionButton button1 = itemBuilder.setContentView(itemIcon).build();

        FloatingActionMenu actionMenu = new FloatingActionMenu.Builder(MainActivity.this)
                .addSubActionView(button1)

                .attachTo(actionButton)
                .build();}

I am getting error in setting the Builder in FloatingActionButton.Builder(this) and error on setting the setImageDrawable

The FloatingActionButton I tried to use is from the com.android.support:design which doesn't have the Builder() method.

You need to use the FloatingActionButton from com.oguzdev:CircularFloatingActionMenu.

Remove import android.support.design.widget.FloatingActionButton; and add

import com.oguzdev.circularfloatingactionmenu.library.FloatingActionButton; wherever you want to use com.oguzdev:CircularFloatingActionMenu's FloatingActionButton
