public void setFocusable
(boolean focusable)

Added in
API level 1

Changes the focusability of the popup window. When focusable, the window will grab the focus from the current focused widget if the popup contains a focusable

View

. By default a popup window is not focusable.

If the popup is showing, calling this method will take effect only the next time the popup is shown or through a manual call to one of the

update()

methods.

改变popWindow是否可以获取焦点的状态。当可以获取焦点的时候，如果popWindow包含可以获取焦点的View，一旦pop弹出就会拿走当前正处于聚焦状态下的视图的焦点，默认情况下pop是不可获取焦点的。

如果pop正处于显示状态，调用这个方法将会在下次弹出的时候起作用，也可以通过调用 updata() 方法使这个方法马上起作用。

Parameters

focusable	true if the popup should grab focus, false otherwise.
