I did it this way:
String widthString = attrs.getAttributeValue("http://

int
int s = Integer.parseInt(widthString.substring(0, 3));On Oct 18, 2:30 pm, Mark Murphy <[email protected]> wrote: > fhucho wrote: > > I have a custom View, it is created from xml - how can I obtain the > > android:layout:width value in the constructor View(Context x, > > AttributeSet a) ? > > 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(); > > (fromhttp://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.
