在窗口小部件中使用ListView会导致“问题加载窗口小部件”

Question

在我的窗口小部件中，我可以将带有“ LinearLayout”的适配器添加为窗口小部件xml文件的“ LinearLayout”中的行，但是当将其添加到“ ListView”时，无法加载该窗口小部件。

如果我注释掉

remoteViews.addView(R.id.widget_LinearLayout_viewContainer, remoteViewsAdapter);

没有内容（当然），但是显示正确。

我认为，“ LinearLayout”应该可添加到“ ListView”（或者我错了吗？）。最糟糕的是，logcat什么也没说。
