将byteArray转换为android中的位图？

Question

在我的web服务中，图像以byteArray格式存储。我想转换位图图像。

我已将此代码附加到此处。

BufferedInputStream bufferedInputStream = new BufferedInputStream(AndroidJSONParsingActivity.inputStream); 
      Bitmap bmp = BitmapFactory.decodeStream(bufferedInputStream); 
      ByteArrayOutputStream companylogo = new 
      ByteArrayOutputStream(); 
      ImageView image=new ImageView(this); 
      image.setImageBitmap(bmp); 

Answer 1

Bitmap bitmap = BitmapFactory.decodeFile("/path/images.jpg"); 
ByteArrayOutputStream blob = new ByteArrayOutputStream(); 
bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, blob); 
byte[] bitmapdata = blob.toByteArray(); 
//if bitmapdata is the byte array then getting bitmap goes like this 

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata , 0, bitmapdata .length); 
Returns The decoded bitmap, or null if the image could not be decode. 

Answer 2

试试这个，

// Camera arg conversion to Bitmap 
Bitmap background = BitmapFactory.decodeByteArray(Your_byte_array_image, 0, 
          Your_byte_array_image.length); 
Bitmap back = Bitmap.createBitmap(background.getWidth(), 
         background.getHeight(), Bitmap.Config.ARGB_8888); 

使用此位图。
