- * A Material-styled button with a customizable background color. On L devices, this is a true
- * Material button. On earlier devices, the button is similar but lacks ripples and a shadow.
- *
- * Create a button in Java:
- *
- *   new ButtonCompat(context, Color.RED);
- *
- * Create a button in XML:
- *
- *   <org.chromium.chrome.browser.widget.ButtonCompat
- *       android:layout_width="wrap_content"
- *       android:layout_height="wrap_content"
- *       android:text="Click me"
- *       chrome:buttonColor="#f00" />
- *
- * Note: To ensure the button's shadow is fully visible, you may need to set
- * android:clipToPadding="false" on the button's parent view.
