如何在android中以编程方式获取设备的完整屏幕尺寸？

Question

我正在以编程方式为平板电脑nexus7“计算设备的屏幕尺寸，它给出6.7。但是Nexus7”屏幕尺寸为7“。 我想获得设备的完整屏幕尺寸。 这是我的代码： -

DisplayMetrics dm = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
        double x = Math.pow(dm.widthPixels / dm.xdpi, 2);
        double y = Math.pow(dm.heightPixels / dm.ydpi, 2);
        screenInches = Math.sqrt(x + y);

尝试以下

int screenSize = getResources().getConfiguration().screenLayout &
        Configuration.SCREENLAYOUT_SIZE_MASK;

switch(screenSize) {
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        Toast.makeText(this, "Large screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        Toast.makeText(this, "Normal screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show();
        break;
    default:
        Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show();
}
