在你的类模型(对象)实现Serializable中，用于 例子:

public class MensajesProveedor implements Serializable {

    private int idProveedor;


    public MensajesProveedor() {
    }

    public int getIdProveedor() {
        return idProveedor;
    }

    public void setIdProveedor(int idProveedor) {
        this.idProveedor = idProveedor;
    }


}

和你的第一项活动

MensajeProveedor mp = new MensajeProveedor();
Intent i = new Intent(getApplicationContext(), NewActivity.class);
                i.putExtra("mensajes",mp);
                startActivity(i);

和你的第二个活动(NewActivity)

        MensajesProveedor  mensajes = (MensajesProveedor)getIntent().getExtras().getSerializable("mensajes");

祝你好运! !

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());
        }

你可以通过intent发送可序列化对象

// send where details is object
ClassName details = new ClassName();
Intent i = new Intent(context, EditActivity.class);
i.putExtra("Editing", details);
startActivity(i);


//receive
ClassName model = (ClassName) getIntent().getSerializableExtra("Editing");

And 

Class ClassName implements Serializable {
} 

public class SharedBooking implements Parcelable{

    public int account_id;
    public Double betrag;
    public Double betrag_effected;
    public int taxType;
    public int tax;
    public String postingText;

    public SharedBooking() {
        account_id = 0;
        betrag = 0.0;
        betrag_effected = 0.0;
        taxType = 0;
        tax = 0;
        postingText = "";
    }

    public SharedBooking(Parcel in) {
        account_id = in.readInt();
        betrag = in.readDouble();
        betrag_effected = in.readDouble();
        taxType = in.readInt();
        tax = in.readInt();
        postingText = in.readString();
    }

    public int getAccount_id() {
        return account_id;
    }
    public void setAccount_id(int account_id) {
        this.account_id = account_id;
    }
    public Double getBetrag() {
        return betrag;
    }
    public void setBetrag(Double betrag) {
        this.betrag = betrag;
    }
    public Double getBetrag_effected() {
        return betrag_effected;
    }
    public void setBetrag_effected(Double betrag_effected) {
        this.betrag_effected = betrag_effected;
    }
    public int getTaxType() {
        return taxType;
    }
    public void setTaxType(int taxType) {
        this.taxType = taxType;
    }
    public int getTax() {
        return tax;
    }
    public void setTax(int tax) {
        this.tax = tax;
    }
    public String getPostingText() {
        return postingText;
    }
    public void setPostingText(String postingText) {
        this.postingText = postingText;
    }
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(account_id);
        dest.writeDouble(betrag);
        dest.writeDouble(betrag_effected);
        dest.writeInt(taxType);
        dest.writeInt(tax);
        dest.writeString(postingText);

    }

    public static final Parcelable.Creator<SharedBooking> CREATOR = new Parcelable.Creator<SharedBooking>()
    {
        public SharedBooking createFromParcel(Parcel in)
        {
            return new SharedBooking(in);
        }
        public SharedBooking[] newArray(int size)
        {
            return new SharedBooking[size];
        }
    };

}

传递数据:

Intent intent = new Intent(getApplicationContext(),YourActivity.class);
Bundle bundle = new Bundle();
i.putParcelableArrayListExtra("data", (ArrayList<? extends Parcelable>) dataList);
intent.putExtras(bundle);
startActivity(intent);

检索数据:

Bundle bundle = getIntent().getExtras();
dataList2 = getIntent().getExtras().getParcelableArrayList("data");

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);

快速需求的简短回答

1. 将类实现为可序列化的。

如果你有任何内部类，不要忘记将它们实现为Serializable !!

public class SportsData implements  Serializable
public class Sport implements  Serializable

List<Sport> clickedObj;

2. 将你的对象放入Intent中

 Intent intent = new Intent(SportsAct.this, SportSubAct.class);
            intent.putExtra("sport", clickedObj);
            startActivity(intent);

3.并在另一个活动类中接收您的对象

Intent intent = getIntent();
    Sport cust = (Sport) intent.getSerializableExtra("sport");
