Programmatically set margin for TableRow

Question

I have TableRows created dynamically in the code and I want to set margins for these TableRows.

My TableRows created as follow

Answer 1

You have to setup LayoutParams properly. Margin is a property of layout and not the TableRow , so you have to set the desired margins in the LayoutParams.

Heres a sample code:

TableRow tr = new TableRow(this);  
TableLayout.LayoutParams tableRowParams=
  new TableLayout.LayoutParams
  (TableLayout.LayoutParams.FILL_PARENT,TableLayout.LayoutParams.WRAP_CONTENT);

int leftMargin=10;
int topMargin=2;
int rightMargin=10;
int bottomMargin=2;

tableRowParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);

tr.setLayoutParams(tableRowParams);

Answer 2

This is working:

TableRow tr = new TableRow(...);
TableLayout.LayoutParams lp = 
new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,
                             TableLayout.LayoutParams.WRAP_CONTENT);

lp.setMargins(10,10,10,10);             
tr.setLayoutParams(lp);

------

// the key is here!
yourTableLayoutInstance.addView(tr, lp);

You need to add your TableRow to TableLayout passing the layout parameters again!
