甲型和甲型六氯环己烷在有效活动将捕获和处理所有关键事件(并可能触动事件)之前,如果它们被传达到本应处理的实际观点,则是否有办法?

I know that we can have onKeyDown or similar method in Activity to handle the keyevent, but it is fired only if none of its child views handles it internally. These view are usually ListView, GridView, ScrollView, etc..

我想找到一种办法,在把关键方法传达给这些观点之前,就要求我采用关键的Handler方法。

我的关键Handler的实施工作非常简单。 它只会在每次活动上打上基调,就像关键语气一样,然后将它推向由这些观点或安康框架所要处理的方式。

由于我的活动和观点很多,我不想在KeyListener上对每一项活动发表看法,因为我很难在任何地方书写同样的法典。 如果有办法,我就可以在基地开展行动,从那时起就开展我的所有活动,并走到我的违约关键手。

I don’t try it myself but I think this one will help you: (just scroll a little bit down to the method mentioned in the text)
