public class NegativeMarginDetector
extends com.android.tools.lint.detector.api.LayoutDetector

Checks for negative margins in the following scenarios:

• In direct layout attribute usages, e.g. <Button android:layoutMargin="-5dp"
• In theme styles, e.g. <item name="android:layoutMargin">-5dp</item>
• In dimension usages, e.g. <Button android:layoutMargin="@dimen/foo" along with <dimen name="foo">-5dp</dimen>
