我想在我的项目中开发一个设置面板,例如google play。它会在我在屏幕上显示时显示。当它移动时,背景变暗。 Firt屏幕是这样 Firt the screen is like this在Android中制作背景昏暗

当我屏幕上滑动时,设定潘内尔移动到前方,同时backgrounf进入滑动暗淡 When i slide the screen, the setting pannel moves to front while backgrounf goes slide dim.

而当设置潘内尔涉及到前cleasrly,背景变得更加暗淡。事实上,随着设置面板向前移动,背景逐渐变暗。 And when setting pannel comes to front cleasrly, background becomes more dim. Actually the background goes to dim gradually as the setting pannel moves to front.

我正在使用android 4.0.3..how来做到这一点。我需要帮助来发展这种观点。
