我对布局很新,但我能够成功地制作一个非常好看的布局(对于平板电脑).在Eclipse中,它运行良好.我在Android 4.0(ICS)上使用'目标'完成了所有操作,但显然我的平板电脑只运行3.0(Honeycomb).当我意识到错误时,我将查看器/编辑配置更改为3.2,但Eclipse甚至不再显示布局的图形,它只是吐出:

com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
    Exception details are logged in Window > Show View > Error Log
    The following classes could not be found:
    - GridLayout (Change to android.widget.GridLayout, Fix Build Path, Edit XML)

弹出错误日志:

我正在尝试制作一个简单的清单.

我有这个:

    String valuesArray[] = {"473", "592", "1774", "341", "355", "473", "950", "500", "44", "946.35", "750", "950"};
    List<String> valueList = Arrays.asList(valuesArray); 

每当我尝试向列表添加内容时,它都会强制关闭.

    valueList.add("Test");

它似乎只有在我尝试添加到列表时才会发生.我可以从列表中获取值,只是不添加它.
