Android gets screen resolution and Displaymetrics

displaymetrics Introduction:Android can be set to scale as the window resizes, but even so, the phone program designer must know the boundaries of the phone screen to avoid the layout distortion caused by scaling. Android provides DISPLAYMETIRCS class for easy access to resolution. The Displaymetrics class under the Andorid.util package provides a general information about the display, such as display size, resolution, and font. To get the Displaymetrics member, first initialize an object as follows:

1. DisplayMetrics metrics ＝newDisplayMetrics();
2. getWindowManager().getDefaultDisplay().getMetrics;
