How to read a file into a Java Bitmap?

问题

I know how to read a bitmap file into a byte array. How is the byte array then converted to a Java Bitmap?

回答1:

Use BitmapFactory if you already have your byte array:

Bitmap bitmap = BitmapFactory.decodeByteArray(yourByteArray, offset, length);

回答2:

Skip the byte array if you want: Bitmap bitmap = BitmapFactory.decodeFile(filename);
