Android transforms the image into stream storage and converts the flow to an image

1. Convert picture to binary stream

 Public byte [] Getbitmapbyte (Bitmap Bitmap) {      new  bytearrayoutputstream ();       // parameter 1 conversion type, parameter 2 compression quality, parameter 3 byte throttle resource    Bitmap.compress (Bitmap.CompressFormat.JPEG,N, out);       Try {          out.flush ();          Out.close ();       Catch (IOException e) {          e.printstacktrace ();      }       return Out.tobytearray ();  }  

2. Change the binary stream into a picture (BITMAP)

 Public Bitmap getbitmapfrombyte (byte[] temp) {      ifnull) {          = Bitmapfactory.decodebytearray (temp, 0, temp.length);           return bitmap;      } Else {          returnnull;      }  }  

Swap binary streams for pictures (drawable)

 Public Drawable getbitmapfrombyte (byte[] temp) {      ifnull) {          = Drawable.createfromstream (Bais, "image");         return drawable;      } Else {          returnnull;      }  }  

3. Convert Bitmap to Drawable

 Public StaticBitmap Drawabletobitmap (drawable drawable) {intwidth =drawable.getintrinsicwidth (); intHeight =drawable.getintrinsicheight (); Bitmap Bitmap=bitmap.createbitmap (width, height, drawable.getopacity ()! = Pixelformat.opaque?Bitmap.Config.ARGB_8888:Bitmap.Config.RGB_565); Canvas Canvas=NewCanvas (bitmap); Drawable.setbounds (0,0, Width,height);                  Drawable.draw (canvas); returnbitmap; }    

Or

New Fastbitmapdrawable (bitmap);  

Or

Bitmapdrawable tempdrawable = (bitmapdrawable) drawable; Tempdrawable.getbitmap ();
