+ * A circular button made of paper that lifts and emits ink reactions on press.
+ * <p/>
+ * This widget supports two sizes: {@link #SIZE_NORMAL} and {@link #SIZE_MINI}
+ * according to <a href="http://www.google.com/design/spec/patterns/promoted-actions.html">Promoted Actions</a> pattern.
+ * <p/>
+ * Like an {@link ImageView} this widget require {@code android:src} attribute.
+ * According to official documentation this drawable should be not more than {@code 24dp}.
+ * <p/>
+ * Use theme to customize all floating buttons in your app:
+ * <p/>
+ * Declare own style:
+ * <pre>
+ * &lt;style name=&quot;AppTheme.Fab&quot; parent=&quot;FloatingActionButton&quot;&gt;
+ *   &lt;item name=&quot;floatingActionButtonColor&quot;&gt;@color/my_fab_color&lt;/item&gt;
+ * &lt;/style&gt;
+ * </pre>
+ * Link this style in your theme:
+ * <pre>
+ * &lt;style name=&quot;AppTheme&quot; parent=&quot;android:Theme&quot;&gt;
+ *   &lt;item name=&quot;floatingActionButtonStyle&quot;&gt;@style/AppTheme.Fab&lt;/item&gt;
+ * &lt;/style&gt;
+ * </pre>
+ * <p/>
+ * Customizing in layout.xml:
+ * <pre>
+ * &lt;com.shamanland.fab.FloatingActionButton
+ *   android:layout_width=&quot;wrap_content&quot;
+ *   android:layout_height=&quot;wrap_content&quot;

+ *   app:floatingActionButtonSize=&quot;mini&quot;
+ *   /&gt;
+ * </pre>
+ * <p/>
+ * Customizing in java-code:
+ * <pre>
+ * 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);
