Android dashed line drawable potential ICS bug
The following is a dashed line, defined as a ShapeDrawable in XML:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line"> <size android:height="2dp" android:width="700dp" /> <stroke android:width="1dp" android:color="@android:color/black" android:dashWidth="1dp" android:dashGap="2dp" /> </shape>
This will draw a nice dotted line on several Gingerbread phones. On the Galaxy Nexus however, the dashes appear to be ignored and the shape is drawn as a contiguous line. Even more curious, an emulator running ICS will render it correctly with the dashes, it’s just the physical device screwing up.
Am I missing something obvious? Or is this really a bug with Android 4.0? The line is used in several places. Here is an example ImageView:
<ImageView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/observation_observe_side_margin" android:layout_marginRight="@dimen/observation_observe_side_margin" android:layout_marginTop="16dp" android:contentDescription="@string/dotted_line_description" android:src="@drawable/dotted_line" />
