Question

问题在于使用GSON的Postegres时间戳序列化，

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.juliandrach.eatfit.MainActivity">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:weightSum="1">

    <ImageView
        android:layout_width="0dp"
        android:layout_height="48dp"
        android:layout_margin="10dp"
        android:layout_weight=".33"
        android:background="@drawable/profilbild" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="2dp"
        android:layout_marginTop="15dp"
        android:layout_weight=".33"
        android:text="Ernährungspläne"
        android:textAllCaps="true"
        android:textColor="@android:color/black"
        android:textSize="21sp" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="2dp"
        android:layout_marginTop="15dp"
        android:layout_weight=".33"
        android:text="Shop"
        android:textAllCaps="true"
        android:textColor="@android:color/black"
        android:textSize="25sp" />
</LinearLayout></RelativeLayout>

预期结果：

private static final GsonBuilder GSON_BASE = Converters
        .registerAll(new GsonBuilder().disableHtmlEscaping())
        .registerTypeAdapter(InfoTransfer.class, new InfoTransfer.Adapter())
        .setDateFormat(DateFormat.FULL, DateFormat.FULL) //Line added but it seems work for MySQL DB Timestamp
        .setPrettyPrinting()
        .create();
.
//inner class in InfoTransfer 
public static class Adapter implements JsonSerializer<InfoTransfer>{

    @Override
    public JsonElement serialize(InfoTransfer src, Type typeOfSrc, JsonSerializationContext context) {

        Gson gson= new Gson();
        JsonObject jsonObject= (JsonObject) gson.toJsonTree(src);

        return new JsonPrimitive(jsonObject.getAsString());
    }
}
.
.
.
Log.d("Result",GSON_BASE.toJson(data));

结果：

"created_at": "2016-10-13 18:18:51.64208+01"

所以有什么建议吗？

日期格式可以设置如下： -

setDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSSX")

示例： -

public static void main(String[] args) { String jsonString = "{\"customorId\":\"506\",\"joiningDate\":\"2016-10-26 19:49:17.290671+01\"}"; Gson gson = new GsonBuilder() .setDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSSX") .setPrettyPrinting() .create(); //Deserialize Customer customer = gson.fromJson(jsonString, Customer.class); System.out.println(customer.toString()); //Serialize Customer customerSerialize = new Customer(); customerSerialize.setCustomorId("123"); customerSerialize.setJoiningDate(new Date()); System.out.println(gson.toJson(customerSerialize)); }

客户类： -

public class Customer implements Serializable { private static final long serialVersionUID = 1100012615187080642L; private String customorId; private Date joiningDate; }

示例输出： -

Customer [customorId=506, joiningDate=Wed Oct 26 19:54:07 BST 2016] { "customorId": "123", "joiningDate": "2016-10-26 20:23:37.000811+01" }
