android获取屏幕分辨率的两种方式

WindowManager windowManager = getWindowManager();
Display display = windowManager.getDefaultDisplay();
int screenWidth = display.getWidth();
int screenHeight =  display.getHeight();

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
