Question

我想在我的Android应用中显示图片。因为我正在调用我的服务，因为图像采用以下格式：

 image:[255,216,255,224,0,16,74,70,73,70,0,1,1,0,0,1,0,1,0,0......].

如何在android中显示此图像。

Answer 1

你能解释得更详细吗？您的图像是否为64格式。如果是这样，您必须解码图像并在imageview中显示它。

 byte[] b = Base64.decode(previouslyEncodedImage, Base64.DEFAULT);
        Bitmap bitmap = BitmapFactory.decodeByteArray(b, 0, b.length);
        img.setImageBitmap(bitmap);

Answer 2

使用以下代码

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

image.setImageBitmap(bmp);

这里是bytearray，你从服务器得到什么

Answer 3

要通知您这称为图像的字节数组，您必须使用Bitmap类的decodeByteArray方法将该数组解码为BitmapFactory，例如，

select(battles,attacker_outcome,attacker_king)
   attacker_outcome            attacker_king
1               win Joffrey/Tommen Baratheon

解释步骤：

String myString = "[255,216,255....]";
try {
    JSONArray arr = new JSONArray(myString);
    byte[] myArray = new byte[myString.length()];
    for (int i = 0; i < arr.length(); i++) {
        myArray[i] = (byte) arr.getInt(i);
    }
    Bitmap bmp = BitmapFactory.decodeByteArray(myArray, 0, myArray.length);
    ImageView image = (ImageView) findViewById(R.id.myImageView);
    image.setImageBitmap(bmp);
} catch (JSONException e) {
    e.printStackTrace();
}
