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:

// Create a TableRow and give it an ID
        TableRow tr = new TableRow(this);       
        tr.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));  
        Button btnManageGroupsSubscriptions = new Button(this);
        btnManageGroupsSubscriptions.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 40));

        tr.addView(btnManageGroupsSubscriptions);
        contactsManagementTable.addView(tr);

How do I dynamically set the margins for these?

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);

Did not work. But the answer of @mik below worked, and should have been the accepted answer – Zvi Jul 16 '16 at 16:42
Strange, it requires double margin as much in programmatic way as manual feed in xml. – Vijay Kumar Kanta Nov 18 '18 at 03:35

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!

Should have been the accepted answer. Without the last line in the answer it does not work 'yourTableLayoutInstance.addView(tr, lp);'. – Zvi Jul 16 '16 at 16:43
