What does "baseline" refer to when used in the context of a relative layout? Simple question, probably, but the documentation and google offer no hints.

The term baseline comes from typography. It's the invisible line letters in text sit on. For example, imagine you put two TextView elements next to each other. You give the second TextView a big padding (say 20dp).
By default, all child views are drawn at the top-left of the layout, so you must define the position of each view using the various layout properties available from RelativeLayout.
Relativelayout is more effective than Linearlayout. It is a common misconception that using the basic layout structures leads to the most efficient layouts. However, each widget and layout you add to your application requires initialization, layout, and drawing.
Android provides the following ViewGroups or layouts: LinearLayout : is a ViewGroup that aligns all children in a single direction, vertically or horizontally. RelativeLayout : is a ViewGroup that displays child views in relative positions.

For example, imagine you put two TextView elements next to each other. You give the second TextView a big padding (say 20dp). If you add layout_alignBaseline to the second element, the text will "scoot up" to align with the baseline of the first element. The text from both elements will appear as if they were written on the same invisible line.
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/text1" android:text="aatlg" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:text="joof" android:background="#00ff00" android:padding="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/text1" android:layout_alignBaseline="@id/text1" /> </RelativeLayout> If you love us?
