LinearLayout not showing an item that was added programatically

I'm trying to add a textview and a button to a linear layout programatically.

The button is showing up but the textview isn't.

Here is my code:

        LinearLayout main = (LinearLayout) findViewById(R.id.mainlayout);
        LinearLayout first = new LinearLayout(this);

        LayoutParams fparams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 5.0f);
        LayoutParams tvparams = new LayoutParams(0, LayoutParams.WRAP_CONTENT);
        LayoutParams btparams = new LayoutParams(0, LayoutParams.WRAP_CONTENT);

        first.setLayoutParams(fparams);
        first.setOrientation(LinearLayout.HORIZONTAL);

        TextView tv = new TextView(this);
        tvparams.weight = 3.0f;
        tv.setLayoutParams(tvparams);

        Button bt = new Button(this);
        btparams.weight = 2.0f;
        bt.setLayoutParams(btparams);

        first.addView(bt);
        first.addView(tv);      
        main.addView(first);
