Use below Code for Convert Byte Array to Bitmap and display this bitmap into ImageView.

Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(bmp);

and see below SO link for more information.

I think you can use BitmapFactory.

public static Bitmap decodeByteArray (byte[] data, int offset, int length)

if your image is in Drawable folder try this code

    Drawable drawable= getResources().getDrawable(R.drawable.yourimage);

    //Type cast to BitmapDrawable
    Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();

    //Write a compressed version of the bitmap to the specified outputstream via compress method.    
    ByteArrayOutputStream out = new ByteArrayOutputStream();

    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
    byte[] buffer  = stream.toByteArray();
