为什么我的TableLayout是不允许被夸大？ [英] Why my TableLayout isn't allowed to be inflated?

问题描述

有关一个widget我用一个简单的布局，其中包含一个TableLayout

For a widget I use a simple layout which contains a TableLayout

<?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，当我想通过创建更新其内容的 RemoteViews

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

我得到一个异常，告诉我， TableLayout 不允许充气。

为什么？

在此先感谢

推荐答案

应用部件只允许可以在它们被用来布局和视图窗口小部件类型的有限列表。它看起来像 TableLayout 不支持。从谷歌开发的documentation:

App widgets only allow limited list of layout and view widget types that can be used within them. It looks like TableLayout isn't supported. From Google developers documentation:

一个RemoteViews对象（并且，
  因此，应用程序窗口小部件）就可以
  支持以下布局类：

A RemoteViews object (and, consequently, an App Widget) can support the following layout classes:

* FrameLayout
* LinearLayout
* RelativeLayout

和下面的小部件类：

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

  
  

这些类的后代不被支持。

Descendants of these classes are not supported.
