如何在安卓系统中将十六进制转换为ImageView

String hexString = "FF0000"; // 十六进制字符串
byte[] byteArray = new byte[hexString.length() / 2];
for (int i = 0; i < byteArray.length; i++) {
    int index = i * 2;
    int value = Integer.parseInt(hexString.substring(index, index + 2), 16);
    byteArray[i] = (byte) value;
}

Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

ImageView imageView = findViewById(R.id.imageView);
imageView.setImageBitmap(bitmap);
