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RemoteViews

来更新其内容时

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

我得到一个例外，告诉我TableLayout不允许被夸大。

为什么？

提前致谢

应用小部件仅允许可在其中使用的有限布局列表和视图小部件类型。看起来似乎不支持TableLayout。来自Google开发人员documentation：

RemoteViews对象（和，因此，一个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。

为什么我的TableLayout不允许膨胀？
