android widget

官方有话这样说：

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

  • FrameLayout
  • LinearLayout
  • RelativeLayout

    • And the following widget classes:

  • AnalogClock
  • Button
  • Chronometer
  • ImageButton
  • ImageView
  • ProgressBar
  • TextView
  • ViewFlipper
  • ListView
  • GridView
  • StackView
  • AdapterViewFlipper

    • Descendants of these classes are not supported.不支持这些类的后代

    接下来的示例说明怎么样实现 使用ListView、GridView、StackView、ViewFlipper创建AppWidget
