为什么我的TableLayout不允许膨胀？

Question

对于小部件,我使用包含TableLayout的简单布局

<?xml version="1.0" encoding="utf-8"?>
<TableLayout  xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <TableRow >
         (...)
    </TableRow>
</TableLayout>

但是,当我想通过创建一个更新其内容时 RemoteViews

RemoteViews eventElementLayout = new RemoteViews( this.getPackageName(), R.layout.widget_events_element );

我有一个例外,告诉我TableLayout不允许膨胀.

应用程序窗口小部件仅允许有限的布局列表和可在其中使用的视图窗口小部件类型.看起来好像TableLayout不受支持.来自Google开发者文档:

RemoteViews对象(以及App Widget)可以支持以下布局类:

* FrameLayout
* LinearLayout
* RelativeLayout

以下小部件类:

* AnalogClock
* Button
* Chronometer
* ImageButton
* ImageView
* ProgressBar
* TextView

不支持这些类的后代.
