android 获取屏幕大小

如何获得屏幕大小：

[java] view
plaincopy

int screenWidth,screenHeight;

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

screenWidth = display.getWidth();

screenHeight = display.getHeight();



也有另一种方法：

[java] view
plaincopy

DisplayMetrics dm = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(dm);

int screenWidth = dm.widthPixels;

int screenHeight = dm.heightPixels;
