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
