我想在另一個片段中使用我自己的數據類型的 ArrayList，我用一個包對其進行測試，并將列表與 putParcelableArrayList 方法放在一起，但它沒有用。任何想法為什么，或更好的建議？片段 1：Bundle arguments = new Bundle();
arguments.putParcelableArrayList("BESTAND", (ArrayList<Bestand>) palBestand);片段 2：ArrayList<Bestand> bestandsliste = (ArrayList<Bestand>) getArguments().getParcelableArrayList("BESTAND");

這是 Parcelable 類的示例
public class Student implements Parcelable{
private String id;
private String name;
private String grade;
// Constructor
public Student(String id, String name, String grade){
this.id = id;
this.name = name;
this.grade = grade;
}
// Getter and setter methods
.........
.........
// Parcelling part
public Student(Parcel in){
String[] data = new String[3];
in.readStringArray(data);
// the order needs to be the same as in writeToParcel() method
this.id = data[0];
this.name = data[1];
this.grade = data[2];
}
@Оverride
public int describeContents(){
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeStringArray(new String[] {this.id,
this.name,
this.grade});
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public Student createFromParcel(Parcel in) {
return new Student(in);
}
public Student[] newArray(int size) {
return new Student[size];
}
};
}
