Android 平板电脑的判断方法

DisplayMetrics dm = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(dm);double diagonalPixels = Math.sqrt(Math.pow(dm.widthPixels, 2) + Math.pow(dm.heightPixels, 2));double physicalSize = diagonalPixels / (160 * dm.density);boolean isTablet = physicalSize > 7;

???? 或者：

boolean isTablet = (getResources().getConfiguration().screenLayout    && Configuration.SCREENLAYOUT_SIZE_MASK)    >= Configuration.SCREENLAYOUT_SIZE_LARGE;
