是否有可能采用Android获取正确绘制的文件夹名称为一个字符串？

Is it possible to retrieve the correct drawable folder name as a String using Android?

例如，我想，作为一个字符串：

For example, I would like, as a string:

String drawableFolder = someFunction.getFolder();
Log.i("", drawableFolder);

....输出：

....to output:

XXDPI

使用情况：我从远程URL下载图像，并想一个机制，以检索设备，适当的图像。它发生在我，我可以prePEND使用正确的名称的URL，例如 https://m.xsw88.com/allimgs/daicuo/20230903/5700.png

Usage case: I'm downloading images from a remote URL and would like a mechanism to retrieve a device-appropriate image. It occurred to me I could prepend the URL with the correct name, e.g. https://m.xsw88.com/allimgs/daicuo/20230903/5700.png

您可以打通器件密度以下

You can get the following through device density

int density= getResources().getDisplayMetrics().densityDpi;

switch(density)
{
case DisplayMetrics.DENSITY_LOW:
    Log.d(TAG, "LDPI");
    break;
case DisplayMetrics.DENSITY_MEDIUM:
     Log.d(TAG, "MDPI");
    break;
case DisplayMetrics.DENSITY_HIGH:
    Log.d(TAG, "HDPI");
    break;
case DisplayMetrics.DENSITY_XHIGH:
     Log.d(TAG, "XHDPI");
    break;
}
