Android ListView 中子控件无法获取焦点的解决方法(主要针对键盘操作)

1。android:descendantFocusability

一般情况下为了使用ListView的onItemClick，onItemLongClick方法，屏蔽子控件对焦点的获取，所以应将该值由

blocksDescendants 改为 afterDescendants

ps：

android:descendantFocusability

Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.

Must be one of the following constant values.

Constant Value Description

beforeDescendants 0 The ViewGroup will get focus before any of its descendants.

afterDescendants 1 The ViewGroup will get focus only if none of its descendants want it.

blocksDescendants 2 The ViewGroup will block its descendants from receiving focus

2.在×××Adapter类的getView中调用子控件的setFocusable属性，及实现相应的Click函数（由于子控件获取焦点后，listview的onItemClick，onItemLongClick不再会被调用，

所以也一并实现，对于onItemLongClick函数，注意要返回TRUE,否则会发现该函数相应的代码会走两遍，估计是ListView的onItemLongClick被触发，有待深究）。

3.调用ListView的setItemsCanFocus（TRUE）函数
