1. Brief IntroductionCoordinate Conversion for Android:This implementation is a linear transformation using 7 Parameters(A, B, C, D, E, F and S) to transform the device coordinates (XD, YD)Into screen coordinates (XS, ys) using the following equations:S * xs = A * XD + B * YD + cS * ys = D * XD + E * YD + FXS, YS: LCD coordinatesXD, YD: Touch screen coordinatesIn

The exhaustive screen map from the previous lesson isn't tied to a participant device form factor, although it can generally look and work okay on a handset or similar-size device. but Android applications need to adapt to a number of different types of devices, from 3 "handsets to 10" tablets to 42 "TVs. in this lesson we recommend e reasons and tactics for grouping together multiple screens from the exhaustive map. http://blog.csdn.net/sergeycao
