Android TextView span full width programmatically

Question

I've created a TextView within a LinearLayout programmatically:

LinearLayout filmTitleContainer = new LinearLayout(ctx);
TextView filmName = new TextView(ctx);
filmName.setBackgroundColor(Color.rgb(Color.YELLOW));
filmName.setText(this.screeningTime+" "+this.name);

The text view is shrunk:

How do I set the text to the occupy the full width of the screen? When I use the XML layout file, I'd set android:layout_width="match_parent". What's the equivalent Java code?

Use LayoutParams for both the view and its container:

LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 1f);
filmTitleContainer.setLayoutParams(params);
filmName.setLayoutParams(params);
