Title Body

Trying to learn some new things and can't figure this one out, any help is appreciated. Given this simple code which is right from Google's documentation: layers.xml: <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/first_image"> <bitmap android:src="@drawable/android_red" android:gravity="center" /> </item> <item android:id="@+id/second_image" android:top="10dp" android:left="10dp"> <bitmap android:src="@drawable/android_green" android:gravity="center" /> </item> <item android:id="@+id/third_image" android:top="20dp" android:left="20dp"> <bitmap android:src="@drawable/android_blue" android:gravity="center" /> </item> </layer-list> And main.xml: <ImageView android:id="@+myImageView" android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/layers" /> Question: How do I programmatically reference one of the drawables in the layer-list so I can change it to a different drawable? Thanks. So now I have my new drawable that I want to swap in in variable myImage correct? Now how do I get that into the layer-list? I assume I use findDrawableByLayerId and setDrawableByLayerId , but how exactly? Or I could be doing it completely wrong! Help! What am I trying to do? Change the drawable that's displayed. For example suppose I had another drawable called "android_purple", how would I switch it in for the "android_green" drawable in the layer-list example above? EDIT: With my limited knowledge here is my code so far (which does not work, I get error that setDrawableByLayerId is undefined): Resources res = get
