实体类实现Parcelable接口需要实现方法：

public ExtSignClockEntity(Parcel in) {
   timeMess = in.readString();     repeatMess = in.readString(); label = in.readString(); ring = in.readString(); isRemind = in.readByte() != 0; }

public static final Creator
    
      CREATOR = new Creator
     
      () {
     @Override     public ExtSignClockEntity createFromParcel(Parcel in) { return new ExtSignClockEntity(in); } @Override public ExtSignClockEntity[] newArray(int size) { return new ExtSignClockEntity[size]; } };
     
    

@Override     public int describeContents() {
      return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(timeMess); dest.writeString(repeatMess); dest.writeString(label); dest.writeString(ring); dest.writeByte((byte)(isRemind?1:0)); } 其中boolean类型的数据输入输出分别为：boolean isCheck; Pacel parcel; 输入： parcel.readByte()!= 0; 输出： isCheck=parcel..writeByte((byte)(isCheck?1:0));
