• 一种继承自linearlayout的布局可以。。


    一种继承自linearlayout的布局可以。在listview中包含checkbox,这时候闹钟的处理时,activity实现一个OnItemClickListener的监听,点击每一项的监听。然后在checkbox单独拿出去写一个类,继承LinearLayout,重写setPressed()这个方法,以实现“当点击checkbox的时候不触发parent的click事件”

             1. The checkbox button resources cannot contain layouts so I have to
                use 2 views for the clock and the bar.
             2. The normal checkbox has a really messed up layout. Using the button
                attribute produces a left-aligned image that has some kind of
                minimum height. If the bar is a checkbox, it is too tall and is
                clipped on the right.
