how can add one.xml or two.xml dynamically in root.xml condition , how can access reference of textview of one.xml file

you have add view using layoutparams.

linearlayout linearlayout = new linearlayout(this);  relativelayout.layoutparams relativeparams = new relativelayout.layoutparams(         layoutparams.fill_parent, layoutparams.fill_parent); relativeparams.addrule(relativelayout.align_parent_top);      parentview.addview(linearlayout, relativeparams); 

to relatively position items programmatically have assign ids them.

textview tv1 = new textview(this); tv1.setid(1);
