I'm trying to achieve the following programmatically (rather than declaratively via XML):
<RelativeLayout...>
<TextView ...
android:id="@+id/label1" />
<TextView ...
android:id="@+id/label2"
android:layout_below: "@id/label1" />
</RelativeLayout>
In other words, how do I make the second TextView
appear below the first one, but I want to do it in code:
RelativeLayout layout = new RelativeLayout(this);
TextView label1 = new TextView(this);
TextView label2 = new TextView(this);
...
layout.addView(label1);
layout.addView(label2);
setContentView(layout);
Update:
Thanks, TreeUK. I understand the general direction, but it still doesn't work – "B" overlaps "A". What am I doing wrong?
RelativeLayout layout = new RelativeLayout(this);
TextView tv1 = new TextView(this);
tv1.setText("A");
TextView tv2 = new TextView(this);
tv2.setText("B");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.RIGHT_OF, tv1.getId());
layout.addView(tv1);
layout.addView(tv2, lp);

From what I've been able to piece together, you have to add the view using LayoutParams.
All credit to sechastain, to relatively position your items programmatically you have to assign ids to them.
Then
addRule(RelativeLayout.RIGHT_OF, tv1.getId());
