//获取屏幕的宽度 public static int getScreenWidth(Context context) {     WindowManager manager = (WindowManager) context             .getSystemService(Context.WINDOW_SERVICE);     Display display = manager.getDefaultDisplay();     return display.getWidth(); } //获取屏幕的高度 public static int getScreenHeight(Context context) {     WindowManager manager = (WindowManager) context             .getSystemService(Context.WINDOW_SERVICE);     Display display = manager.getDefaultDisplay();     return display.getHeight(); }

方法2：

 

DisplayMetrics  dm = new DisplayMetrics();        getWindowManager().getDefaultDisplay().getMetrics(dm);        int screenWidth = dm.widthPixels;                  int screenHeight = dm.heightPixels;
