怎么样才可以在DirectionalLayout里添加组件？

我想在 DirectionalLayout 里面添加两个组件，代码如下：
private void  initTabMenu(){
DirectionalLayout tabMenu = findComponentById(ResourceTable.Id_tabMenu);
DirectionalLayout tabMenuItem1 =
         (DirectionalLayout) LayoutScatter.getInstance(getContext()).parse(ResourceTable.Layout_tab_menuitem, tabMenu, false);
Image image1 = tabMenuItem1.findComponentById(ResourceTable.Id_tab_menu_item_image);
image1.setPixelMap(ResourceTable.Media_fruit_icons_01);
Text text1 = tabMenuItem1.findComponentById(ResourceTable.Id_tab_menu_item_text);
text1.setText("Menu1");
tabMenu.addComponent(tabMenuItem1);
DirectionalLayout tabMenuItem2 =
         (DirectionalLayout) LayoutScatter.getInstance(getContext()).parse(ResourceTable.Layout_tab_menuitem, tabMenu, false);
Image image2 = tabMenuItem2.findComponentById(ResourceTable.Id_tab_menu_item_image);
image2.setPixelMap(ResourceTable.Media_fruit_icons_02);
Text text2 = tabMenuItem2.findComponentById(ResourceTable.Id_tab_menu_item_text);
text2.setText("Menu2");
tabMenu.addComponent(tabMenuItem2);
}

实际却只有一个组件添加上了：
