To get at a custom attribute, you would use code like this:

TypedArray a=ctxt.obtainStyledAttributes(attrs,
R.styleable.Meter,
0, 0);

max=a.getInt(R.styleable.Meter_max, 100);
incrAmount=a.getInt(R.styleable.Meter_incr, 1);
decrAmount=-1*a.getInt(R.styleable.Meter_decr, 1);

a.recycle();

(from http://github.com/commonsguy/cw-advandroid/tree/master/Views/Meter/)

For android:layout_width, presumably you would use
android.R.styleable.ViewGroup_Layout_layout_width, though I have not
tried that.

However, in theory, that attribute should be handled for you, I would
think. You would negotiate the size in onMeasure().
