在 appwidget 中输入

Question

从appwidget 获取意见的最佳方式是什么。我知道我可以使用RemoteViews 中的setOnClickPendingIntent 方法，但我不想那样做！有没有其他方法？ 附言当我尝试在 Xml (<ImageView android:onClick="myHandler" ... />) 中注册 onClick 侦听器时，它会引发异常。

我知道我可以使用 RemoteViews 中的 setOnClickPendingIntent 方法，但我不想那样做！

您别无选择。它是您通过 API 级别 10（姜饼）的唯一输入选项。

对于 API 级别 11 及更高级别（Honeycomb 等），您可以创建包含 ListView、GridView 和 StackView 的应用小部件。对于这些，您可以提供另一个PendingIntent，当单击列表（或网格或堆栈）中的项目时将调用该PendingIntent。这将类似于setOnClickPendingIntent()。
