Android bitmap对象序列化

      由于BitMap没有实现序列化接口，所以当序列化到本地或者在activity之间序列化传递时，会报异常。

在这里介绍个简单的方法实现序列化BitMap：

   可以将bitmap对象转换成byte[]，然后再序列化或者传递，相反同样可以把byte[]转换成bitma对象。变相的传递序列化Bitmap。

代码如下：

    bitmap对象和byte[]的相互转换

public byte[] getBytes(Bitmap bitmap){      ByteArrayOutputStream baos = new ByteArrayOutputStream();      bitmap.compress(Bitmap.CompressFormat.PNG, 0, baos);    return baos.toByteArray();} public  Bitmap getBitmap(byte[] data){        return BitmapFactory.decodeByteArray(data, 0, data.length);}

序列化bitmap对象到本地和发序列化：

public void saveInputTypeEditTextDataToFile(Object object,String fileName){ObjectOutputStream objectOutputStream = null;try {FileOutputStream fileOutputStream = mContext.openFileOutput(fileName,Context.MODE_PRIVATE);objectOutputStream = new ObjectOutputStream(fileOutputStream);objectOutputStream.writeObject(object);objectOutputStream.flush();} catch (IOException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}finally{if (objectOutputStream != null) {try {objectOutputStream.close();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}public byte[] readBitmapDataFromFile(String fileName){ObjectInputStream objectInputStream = null;try {FileInputStream fileInputStream = mContext.openFileInput(fileName);objectInputStream = new ObjectInputStream(fileInputStream);byte[] editTexts = (byte[]) objectInputStream.readObject();return editTexts;} catch (StreamCorruptedException e) {e.printStackTrace();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}catch (Exception e) {e.printStackTrace();}finally{if (objectInputStream != null) {try {objectInputStream.close();} catch (IOException e) {e.printStackTrace();}}}return null;}

之后就可以根据你自己的逻辑对bitmap进行处理了。
