It's very simple, override the 3 following methods:
@Override
public ViewGroup.LayoutParams generateLayoutParams(AttributeSet attrs) {
return new CellLayout.LayoutParams(getContext(), attrs);
}
@Override
protected boolean checkLayoutParams(ViewGroup.LayoutParams p) {
return p instanceof CellLayout.LayoutParams;
}
@Override
protected ViewGroup.LayoutParams
generateLayoutParams(ViewGroup.LayoutParams p) {
return new CellLayout.LayoutParams(p);
}
Also, the styleable name for your layout params should follow our
convention and be called MyLayout_Layout. The attributes should be
called layout_myattribute. The complete name of an attribute is:
my.app.R.styleable.MyLayout_Layout_layout_myattribute
