我班上有一个ArrayList
。我尝试将其传递给Parcelable
,但收到错误。
下面是类的结构和代码本身。我怎样才能传递这类数据?
类
class Lists{
String name_opt;
byte[] value;
}
class ConfigStruct{
String page;
String name;
String type;
byte[] val_size;
byte[] max_lenght;
byte[] min_lenght;
byte[] value;
List<Lists> list;
View view;
}
ConfigStructParcelable
public class ConfigStructParcelable implements Parcelable {
List<Tabs.ConfigStruct> structs;
public ConfigStructParcelable(ArrayList<Tabs.ConfigStruct> data){
this.structs = data;
}
public ConfigStructParcelable(Parcel in){
this.structs = in.readArrayList(null);//?
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeList(structs); //?
}
public static Creator<ConfigStructParcelable> CREATOR = new Creator<ConfigStructParcelable>() {
@Override
public ConfigStructParcelable createFromParcel(Parcel source) {
return new ConfigStructParcelable(source);
}
@Override
public ConfigStructParcelable[] newArray(int size) {
return new ConfigStructParcelable[size];
}
};
}
我标记了两个位置&#34; //?&#34;了解如何正确写入包裹以及如何重建包裹。
发布链接没有帮助。
