如何在Android中序列化ViewGroup的对象？

我使用过此代码，但它不起作用，我没有序列化

 public void saveObject(ViewGroup v){
   try
   {

   ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(saved_image_file)); //Select where you wish to save <span id="IL_AD3" class="IL_AD">the file</span>...
                   oos.writeObject(v); // write the class as an 'object'
                   oos.flush(); // flush the <span id="IL_AD8" class="IL_AD">stream</span> to insure all of the information was written to 'save_object.bin'
                   oos.close();// close the stream
                }
                catch(Exception ex)
                {
                   Log.v("Serialization Save Error : ",ex.getMessage());
                   ex.printStackTrace();
                }
           }

           public ViewGroup loadSerializedObject(File f)
           {
               try
               {


                   ObjectInputStream ois = new ObjectInputStream(new FileInputStream(f));
                   Log.e("object sasasasasa","aaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
                   Log.e("object sasasasasa", ois.readObject()+"");
                   ViewGroup o =(ViewGroup)ois.readObject();
                   return o;

               }
               catch(Exception ex)
               {
               Log.v("Serialization Read Error : ",ex.getMessage());
                   ex.printStackTrace();
               }
               return null;
           }

扩展未实现的。所以，这是不可能的。

我已经把错误放在这里了，请帮助我。这个

notserializableeexception

中有什么不清楚的地方？

ViewGroup

是不可序列化的，您不能从视图层次结构中序列化任何内容。检查一下，你可能会明白为什么。我建议制作一个定制的holder类。
