这个问题并不复杂,但是问的人实在很多,所以还是集中回答一下。
从Android 3.2(API Level 13)开始,在Activity里使用下面的方法来获取屏幕尺寸(单位是像素):
Display display = getWindowManager().getDefaultDisplay(); //Activity#getWindowManager() Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y;
如果代码不是写在Activity里,用下面的方法(通过WINDOW_SERVICE获取display对象):
WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); display.getSize(size); int width = size.x; int height = size.y;
如果Android版本小于3.2,那么因为Display对象还没有getSize()方法,应该用下面的方法获取屏幕尺寸:
Display display = getWindowManager().getDefaultDisplay(); int width = display.getWidth(); int height = display.getHeight();
