When I first experimented with LayerDrawables, I thought something was broken in the way I was loading drawables and initialising the LayerDrawable.
Here's what it looks like on Android 4.1 (API 16) and Android 4.4 (API 19)
For each background and border, I had a drawable defined in XML files. Upon testing the layers individually, the background was loaded fine, however the border drawable was causing the black from appearing.
Here's an example of "cell_border_event.xml" shape drawable:
1.<?xml version="1.0" encoding="utf-8"?> 2. <shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android"> 3. <stroke android:color="@color/cell_border_event" android:width="3dp"></stroke> 4. </shape>It seems that for Android 4.1 and lower, the shape drawables require a definition for the solid colour attribute. Prior to Android 4.4 the default was black.
1.<?xml version="1.0" encoding="utf-8"?> <shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android"> 2.<!-- Android 4.1 renders this black if this isn't specified --> 3.<solid android:color="@android:color/transparent" /> 4.<stroke android:color="@color/cell_border_annual" android:width="3dp"></stroke> 5.</shape>After adjusting this for all the border shapes, it now looks consistent.
Eh, looks about right to me.
