Bitmap logoBitmap = BitmapFactory.decodeResource(mcontext.getResources(), R.drawable.arcnote_logo);ByteArrayOutputStream logoStream = new ByteArrayOutputStream();boolean res = logoBitmap.compress(Bitmap.CompressFormat.PNG,100,logoStream);//将图像读取到logoStream中byte[] logoBuf = logoStream.toByteArray();//将图像保存到byte[]中Bitmap temp = BitmapFactory.decodeByteArray(logoBuf,0,logoBuf.length);//将图像从byte[]中读取生成Bitmap 对象 tempsaveMyBitmap("tttt",temp);//将图像保存到SD卡中public void saveMyBitmap(String bitName,Bitmap mBitmap){ File f = new File("/sdcard/" + bitName + ".png"); try { f.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block } FileOutputStream fOut = null; try { fOut = new FileOutputStream(f); } catch (Exception e) { e.printStackTrace(); } mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut); try { fOut.flush(); } catch (IOException e) { e.printStackTrace(); } try { fOut.close(); } catch (IOException e) { e.printStackTrace(); }} |
希望本文所述对大家的Android程序设计有所帮助。
