我想才达到以下编程方式（而不是通过XML声明）：

 ＆LT; RelativeLayout的...＆GT;
   ＆LT; TextView中...
      机器人：ID =@ + ID / label1的/＆GT;
   ＆LT; TextView中...
      机器人：ID =@ + ID / LABEL2
      机器人：layout_below：@用户名/卷标1/＆GT;
＆LT; / RelativeLayout的＆GT;
 

在换句话说，如何让我的第二个TextView的出现下面的第一个，但我想这样做在code：

  RelativeLayout的布局=新RelativeLayout的（这一点）;
TextView的卷标1 =新的TextView（本）;
TextView的标签2 =新的TextView（本）;
...
layout.addView（LABEL1）;
layout.addView（LABEL2）;
的setContentView（布局）;
 

更新：

谢谢，TreeUK。我理解的大方向，但它仍然无法正常工作 - B重叠A。我究竟做错了什么？

  RelativeLayout的布局=新RelativeLayout的（这一点）;
TextView的TV1 =新的TextView（本）;
tv1.setText（A）;

TextView的TV2 =新的TextView（本）;
tv2.setText（B）;
RelativeLayout.LayoutParams LP =新RelativeLayout.LayoutParams（
        RelativeLayout.LayoutParams.WRAP_CONTENT，RelativeLayout.LayoutParams.FILL_PARENT）;
lp.addRule（RelativeLayout.RIGHT_OF，tv1.getId（））;

layout.addView（TV1）;
layout.addView（TV2，LP）;
 

解决方案

从我已经能够拼凑，你必须使用的LayoutParams添加视图。

 的LinearLayout的LinearLayout =新的LinearLayout（本）;

RelativeLayout.LayoutParams relativeParams =新RelativeLayout.LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.FILL_PARENT）;
relativeParams.addRule（RelativeLayout.ALIGN_PARENT_TOP）;

parentView.addView（LinearLayout中，relativeParams）;
 

所有信贷sechastain，编程，你必须IDS分配给他们相对定位您的项目。

  TextView的TV1 =新的TextView（本）;
tv1.setId（1）;
TextView的TV2 =新的TextView（本）;
tv2.setId（2）;
 

然后 addRule（RelativeLayout.RIGHT_OF，tv1.getId（））;

I'm trying to achive 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.

LinearLayout linearLayout = new LinearLayout(this);

RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
relativeParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);

parentView.addView(linearLayout, relativeParams);

All credit to sechastain, to relatively position your items programmatically you have to assign ids to them.

TextView tv1 = new TextView(this);
tv1.setId(1);
TextView tv2 = new TextView(this);
tv2.setId(2);

Then addRule(RelativeLayout.RIGHT_OF, tv1.getId());
