This work for me  and I hope it will work for you also   Set the LayoutParams for the parent view first   myTableLayout setLayoutParams new TableLayout LayoutParams TableLayout LayoutParams FILL PARENT                  TableLayout LayoutParams FILL PARENT      then set for the TextView  child     TableLayout LayoutParams textViewParam   new TableLayout LayoutParams       TableLayout LayoutParams WRAP CONTENT       TableLayout LayoutParams WRAP CONTENT 1f          -- set components margins      textViewParam setMargins 5  0  5 0        myTextView setLayoutParams textViewParam

The answer is that you have to use TableRow LayoutParams  not LinearLayout LayoutParams or any other LayoutParams   TextView tv   new TextView v getContext     LayoutParams params   new TableRow LayoutParams 0  LayoutParams WRAP CONTENT  1f   tv setLayoutParams params     The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen   The text view s parent is a table row  hence   http   developer android com reference android widget TableRow LayoutParams html

I had a fair amount of difficulty with a solution something very similar to this  trying to have two buttons in a TableRow  with each being half the screen width   For whatever reason  the left button would always be about 70  of the width  and the right button 30    Calling table layout setStretchAllColumns true  had no effect  nor did setting the button s width to half the screen  nor setting their layout weight     The solution I ended up with was nesting a LinearLayout in the TableRows  which did take into account the value of the buttons  width       TableLayout layout   new TableLayout this       TableRow top row   new TableRow this       left button   styleButton        right button   styleButton        LinearLayout toprow layout   new LinearLayout  this       toprow layout setOrientation LinearLayout HORIZONTAL       toprow layout addView  left button       toprow layout addView right button       toprow addView top layout       layout addView top row       private Button styleButton                 Button btn   new Button  this               android view Display display     android view WindowManager getSystemService Context WINDOW SERVICE   getDefaultDisplay                      btn setWidth  int  display getWidth   2          set width to half             btn setHeight   int display getHeight   6        set height to whatevs             btn setText  foo                return btn

In the earlier answers weight is passed to the constructor of a new SomeLayoutType LayoutParams object  Still in many cases it s more convenient to use existing objects - it helps to avoid dealing with parameters we are not interested in   An example      Get our View  TextView or anything  object  View v   findViewById R id our view        Get params  LinearLayout LayoutParams loparams    LinearLayout LayoutParams  v getLayoutParams        Set only target params  loparams height   0  loparams weight   1  v setLayoutParams loparams

There is another way to do this  In case you need to set only one parameter  for example  height    TextView textView    TextView findViewById R id text view   ViewGroup LayoutParams params   textView getLayoutParams    params height   ViewGroup LayoutParams WRAP CONTENT  textView setLayoutParams params

You have to use TableLayout LayoutParams with something like this   TextView tv   new TextView v getContext     tv setLayoutParams new TableLayout LayoutParams LayoutParams WRAP CONTENT  LayoutParams WRAP CONTENT  1f      The last parameter is the weight
