字节数组可以存储为BLOB数据types。 这个过程没有什么特别之处,除非特别注意组块,例如:

InputStream is = context.getResources().open(R.drawable.MyImageFile); try { byte[] buffer = new byte[CHUNK_SIZE]; int size = CHUNK_SIZE; while(size == CHUNK_SIZE) { size = is.read(buffer); //read chunks from file if (size == -1) break; ContentValues cv = new ContentValues(); cv.put(CHUNK, buffer); //CHUNK blob type field of your table long rawId = database.insert(TABLE, null, cv); //TABLE table name } } catch (Exception e) { Log.e(TAG, "Error saving raw image to: "+rawId, e); }
