我知道有点晚了，但很简单。你所要做的就是让你的类实现Serializable

public class MyClass implements Serializable{

}

然后你可以传递给一个意图，比如

Intent intent=......
MyClass obje=new MyClass();
intent.putExtra("someStringHere",obje);

要得到它，你只需打电话

MyClass objec=(MyClass)intent.getExtra("theString");

我也遇到过同样的问题。我通过使用一个静态类来解决这个问题，在HashMap中存储我想要的任何数据。在上面，我使用了标准活动类的扩展，其中我覆盖了onCreate和onDestroy方法来做数据传输和数据清除隐藏。一些荒谬的设置必须改变，例如方向处理。

注释: 不提供一般对象传递给另一个活动是痛苦的屁股。这就像射击自己的膝盖，希望赢得100米。“比喻”并不是一个充分的替代品。这让我笑了……我不想实现这个接口到我的技术自由API，因为我更不想引入一个新的层…这是怎么回事，我们在移动编程中离现代范式如此之远……

对于你知道要在应用程序中传递数据的情况，使用“全局变量”(比如静态类)

以下是Dianne Hackborn (hackbod -谷歌安卓软件工程师)对此事的看法:

For situations where you know the activities are running in the same process, you can just share data through globals. For example, you could have a global HashMap<String, WeakReference<MyInterpreterState>> and when you make a new MyInterpreterState come up with a unique name for it and put it in the hash map; to send that state to another activity, simply put the unique name into the hash map and when the second activity is started it can retrieve the MyInterpreterState from the hash map with the name it receives.

谢谢你的帮助，但我发现了一个可选的解决方案

 public class getsetclass implements Serializable {
        private int dt = 10;
    //pass any object, drwabale 
        public int getDt() {
            return dt;
        }

        public void setDt(int dt) {
            this.dt = dt;
        }
    }

活动一

getsetclass d = new getsetclass ();
                d.setDt(50);
                LinkedHashMap<String, Object> obj = new LinkedHashMap<String, Object>();
                obj.put("hashmapkey", d);
            Intent inew = new Intent(SgParceLableSampelActivity.this,
                    ActivityNext.class);
            Bundle b = new Bundle();
            b.putSerializable("bundleobj", obj);
            inew.putExtras(b);
            startActivity(inew);

在活动2中获取数据

 try {  setContentView(R.layout.main);
            Bundle bn = new Bundle();
            bn = getIntent().getExtras();
            HashMap<String, Object> getobj = new HashMap<String, Object>();
            getobj = (HashMap<String, Object>) bn.getSerializable("bundleobj");
            getsetclass  d = (getsetclass) getobj.get("hashmapkey");
        } catch (Exception e) {
            Log.e("Err", e.getMessage());
        }

Intent i = new Intent();
i.putExtra("name_of_extra", myParcelableObject);
startACtivity(i);

Start another activity from this activity pass parameters via Bundle Object

Intent intent = new Intent(this, YourActivity.class);
Intent.putExtra(AppConstants.EXTRAS.MODEL, cModel);
startActivity(intent);
Retrieve on another activity (YourActivity)

ContentResultData cModel = getIntent().getParcelableExtra(AppConstants.EXTRAS.MODEL);
