// ...

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

ListView listView = (ListView) findViewById(android.R.id.list);

Customizing

Use theme to customize all floating buttons in your app:

Declare own style:

<style name="AppTheme.Fab" parent="FloatingActionButton">
    <item name="floatingActionButtonColor">@color/my_fab_color</item>
</style>

Link this style in your theme:

<style name="AppTheme" parent="android:Theme">
    <item name="floatingActionButtonStyle">@style/AppTheme.Fab</item>
</style>

Customizing in layout.xml:

<com.shamanland.fab.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_my"
    app:floatingActionButtonColor="@color/my_fab_color"
    app:floatingActionButtonSize="mini"
    />

Customizing in java-code:

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setSize(FloatingActionButton.SIZE_MINI);
fab.setColor(Color.RED);
// NOTE invoke this method after setting new values!
fab.initBackground();
// NOTE standard method of ImageView
fab.setImageResource(R.drawable.ic_action_my);
