Adding content to a linear layout dynamically

Question

If for example I have defined a root linear layout whose orientation is vertical   main xml    lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android        android id    id my root        android layout height  wrap content        android layout width  fill parent        android orientation  vertical        lt  -- I would like to add content here dynamically -- gt    lt  LinearLayout gt    Inside the root linear layout  I would like to add multiple child linear layouts  each of the child linear layout orientation is horizontal  With all these I could end up with a table like output    For example root with child layout such as    lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android        android id    id my root        android layout height  wrap content        android layout width  fill parent        android orientation  vertical        lt  -- 1st child  1st row -- gt       lt LinearLayout                     android orientation  horizontal  gt              lt TextView      gt             lt TextView      gt             lt TextView      gt       lt  LinearLayout gt         lt  -- 2nd child  2nd row -- gt            lt  LinearLayout gt    Since the number of child linear layouts and their contents are quite dynamic  I ve decide to add content to the root linear layout programmatically    How can the second layout be added to the first programmatically  which could also set all the layout attributes for each child and add more other elements inside child
