How to get high density bitmap from resource

Question

According to Google's iconography , I added my application icon (ic_launcher) in multiple densities. And it works correctly. But how can I programmatically get the icon in code?

Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher);

Usually I use this code, but I always decode an image of 64x64 dimension which none of my original icons has. How can I force the BitmapFactory to decode for instance XXXHPDI ?

Answer 1

从API级别15开始，您可以在此处使用以下方法：

getResources().getDrawableForDensity(id, density);

Answer 2

try this,

BitmapFactory.Options options = new BitmapFactory.Options();// whichever you want to load
options.inDensity = DisplayMetrics.DENSITY_MEDIUM;
options.inTargetDensity = getResources().getDisplayMetrics().densityDpi;
options.inScaled = true;
