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 {
} 

您需要将对象序列化为某种字符串表示形式。一种可能的字符串表示是JSON，如果你问我，在android中序列化JSON最简单的方法之一是通过谷歌GSON。

在这种情况下，你只需要输入字符串返回值from (new Gson()).toJson(myObject);并检索字符串值并使用fromJson将其转换回您的对象。

但是，如果您的对象不是非常复杂，那么可能不值得这样做，您可以考虑传递对象的单独值。

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);

在臂膀上

在build.gradle中添加kotlin扩展。

apply plugin: 'kotlin-android-extensions'

android {
    androidExtensions {
        experimental = true
   }
}

然后像这样创建数据类。

@Parcelize
data class Sample(val id: Int, val name: String) : Parcelable

传递带有意图的对象

val sample = Sample(1,"naveen")

val intent = Intent(context, YourActivity::class.java)
    intent.putExtra("id", sample)
    startActivity(intent)

获取带有意图的对象

val sample = intent.getParcelableExtra("id")

第一个活动:

intent.putExtra("myTag", yourObject);

在你的第二篇文章中:

myCustomObject myObject = (myCustomObject) getIntent().getSerializableExtra("myTag");

别忘了让你的自定义对象Serializable:

public class myCustomObject 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");
