得到位图后做这种方式

Bitmap new_bmp = Bitmap.createBitmap(bm, 0, 0, linear.getWidth(), linear.getHeight(), matrix, false); 

      image.draw(new Canvas(new_bmp)); 
      String s = Environment.getExternalStorageDirectory().toString(); 

      linear.setBackgroundColor(Color.BLACK); 
      OutputStream outStream = null; 
      SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_hhmmss"); 
      String file_name = sdf.format(new Date())+".PNG"; 
      File file = new File(s, file_name); 
      try { 
      outStream = new FileOutputStream(file); 
      new_bmp.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
      outStream.flush(); 
      outStream.close(); 
      } catch (FileNotFoundException e) { 
       e.printStackTrace(); 
       Toast.makeText(CaptureImage.this, e.toString(), Toast.LENGTH_LONG).show(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
       Toast.makeText(CaptureImage.this, e.toString(), Toast.LENGTH_LONG).show(); 
      }
