android - 我可以在 appWidget 中使用哪些 View ？

Question

谁能告诉我可以在 appWidget 中使用哪些 View ？

谢谢!

Answer 1

根据official android API :

RemoteViews 对象(以及因此的 App Widget)可以支持以下布局类:

• FrameLayout
• LinearLayout
• RelativeLayout
• GridLayout

And the following widget classes:

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

Descendants of these classes are not supported.

RemoteViews also supports ViewStub, which is an invisible, zero-sized View you can use to lazily inflate layout resources at runtime.

同样以android 3.0开头支持下一个 View :

• ListView - A view that shows items in a vertically scrolling list. For an example, see the Gmail app widget.
• GridView - A view that shows items in two-dimensional scrolling grid. For an example, see the Bookmarks app widget.
• StackView - A stacked card view (kind of like a rolodex), where the user can flick the front card up/down to see the previous/next card, respectively. Examples include the YouTube and Books app widgets.
• AdapterViewFlipper - An adapter-backed simple ViewAnimator that animates between two or more views. Only one child is shown at a time.
