+### **Rect**
+>+ openharmony API: ohos.utils.Sequenceable
+>+ openharmony SDK版本：2.1.1.21 以上
+>+ IDE版本：2.1.0.501
+>+ 实现方案：实现Sequenceable接口，并实现Producer<Rect>()方法:
+
+```java
+public class Rect implements Sequenceable {
+    public static final Producer<Rect> PRODUCER = new Producer<Rect>() {
+        @Override
+        public Rect createFromParcel(Parcel source) {
+            return new Rect(source);
+        }
+    };
+}
+```
+
+>+ 补充说明：
+>+ 鸿蒙的ohos.agp.utils.Rect类的反序列化失败
+>+ 安卓实现对应类：Parcel.writeParcelable   Parcel.readParcelable ，
+>+ 鸿蒙对应的实现方法：
+```java
+    Rect rect = new Rect(10, 20, 30, 40);
+    MessageParcel _data = MessageParcel.obtain();
+    _data.writeTypedSequenceable(rect);
+    Object obj = _data.createSequenceable();
+```
+>+ 结果鸿蒙的ohos.agp.utils.Rect类的反序列化失败（报 Exception message: ohos.utils.ParcelException: fail to create sequenceable creator due to NoSuchFieldException: PRODUCER, class:ohos.agp.utils.Rect错误），
+>+ 问题原因:需要实现这个类Sequenceable接口和Producer，实现Sequenceable接口和Producer<Rect>()方法。
