//該方法實現圖片轉String 參數為圖片的路徑 可以是file.toString()得到
public String testUpload(String path) { try { String srcUrl = path; // "/mnt/sdcard/"; //路徑 // String fileName = PhotoName+".jpg"; //文件名 FileInputStream fis = new FileInputStream(srcUrl); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buffer = new byte[65536]; int count = 0; while ((count = fis.read(buffer)) >= 0) { baos.write(buffer, 0, count); } String uploadBuffer = new String(Base64.encode(baos.toByteArray())); // 進行Base64編碼 fis.close();//這兩行原來沒有 baos.flush(); return uploadBuffer; } catch (Exception e) { e.printStackTrace(); } // return soapObject; return null; }
//以下實現String轉bitmap
String respon;//respon 為 圖片轉String得到的字符串
byte[] decode1 = Base64.decode(response ,Base64.DEFAULT); bitmap bm1 = BitmapFactory.decodeByteArray(decode1, 0, decode1.length); downloadImgView.setImageBitmap(bm1);
