title: LinearLayout is only allowing one view to be added
body: <pre><code>  layout = new LinearLayout(this);
              addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
  
  
              Button btn = new Button(this);
              btn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
             btn.setText("button");
  
              layout.addView(btn);
  
              Button btn1 = new Button(this);
              btn1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
             btn1.setText("button");
  
              layout.addView(btn1);
  </code></pre>
  
  <p>I know I must be missing something because whenever I add views to this layout I only have one of them show up.</p>
