         TableLayout tl = (TableLayout)findViewById(R

Your TextViews are children of a TableRow so you should set an instance of TableRow.LayoutParams for the LayoutParams instead of the simple one(probably from the ViewGroup super class) that you currently use:

//...
        TextView tv = new TextView(this);
        tv.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,
                TableRow.LayoutParams.WRAP_CONTENT));
        tv.setText("text 1");
        tr.addView(tv);

        TextView tv1 = new TextView(this);
        tv1.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,
                TableRow.LayoutParams.WRAP_CONTENT));
        tv1.setText("text 2");
        tr.addView(tv1);

        TextView tv2 = new TextView(this);
        tv2.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,
                TableRow.LayoutParams.WRAP_CONTENT));
        tv2.setText("text 3");
        tr.addView(tv2);
//...
