How to resolve layout object/method references in ActivityMain.java

[jonmelvin]

Starting Android coding using java only (no layout xml). In ActivityMain.java, onCreate,
added LinearLayout ll = new LinearLayout(this); and to resolve "LinearLayout" had to add
import android.widget.*; But now ll.onOrientation shows "onOrientation" in red. How does
one find out how to resolve references in the java code?
