Android view dithering.

Question

As you can see from the screenshot below, the "titlebar" is getting these ugly banding lines across the areas with text that extend the entire width of the screen. It's even more noticeable on a real device.

Is there any way to work around this?

Answer 1

From Android Developers: Widget Design Guidelines:

In some cases, devices have low pixel depths that can cause visual banding and dithering issues. To solve this, application developers should pass assets through a "proxy" drawable defined as XML:. This technique references the original artwork, in this case "background.9.png", and instructs the device to dither it as needed.

EDIT: Example source. This is an xml file in your res/drawables directory:

<?xml version="1.0" encoding="UTF-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/title_bar_medium"
    android:dither="true" />
