android：如何找出设备的非触摸敏感填充
对于绘图应用程序，我必须确保画布不大于屏幕的可触摸区域，否则我会在画布上有填充，用户无法在其中绘图。
我猜我的 Galaxy S 上的像素约为 10 像素。 有没有办法找出非触摸敏感像素的确切数量？
For a drawing app, I have to make sure that the canvas is not bigger then the touchable area of the screen, cause otherwise I would have a padding on the canvas, where it is not possible for the user to draw on.
On my Galaxy S that's about 10 pixel I guess.
Is there a way to find out the exact number of pixels which are not touch-sensitive?

抱歉，但这没有意义。我认为也许组件还不够好，但是android中的屏幕必须具有触摸所有窗口位置的能力。
如果你有理由而制片人犯了那个可怕的错误，程序认为你没有整个可触摸区域，那么你会给做得很好的制片人带来坏事。
无论如何，如果您考虑用户的可用性，请不要使用像素，而应使用dip。
Sorry but that has no sense . I think that maybe components are not good enough , but the screen in android must have the capability to touch all window places .
If you have the reason and the producer make that horrible mistake , program thinking that you don't have the whole touchable area , you would make a bad thing for producers that do it well.
Anyway if you are thinking in usability for users , don't work with pixels , work with dip .
