不可包裹的异常

Question

首先，我必须说，我一直在此站点上寻找我的问题的答案，我发现了有关此异常的多个主题，但毕竟所有主题对我没有太大帮助，所以这就是为什么我要发布这个。

每次尝试从包裹中恢复信息时，我都会遇到“包裹不可修复”异常。这是我的班级代码。

public class Persona implements Parcelable {

private String nombre,email,tel;

public Persona() {
    nombre = "";
    email = "";
    tel = "";
}

public Persona(String nombre, String email, String tel) {
    this.nombre = nombre;
    this.email = email;
    this.tel = tel;
}

public Persona(Parcel p){
    setNombre(p.readString());
    setEmail(p.readString());
    setTel(p.readString());
}

public String getNombre() {
    return nombre;
}

public void setNombre(String nombre) {
    this.nombre = nombre;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getTel() {
    return tel;
}

public void setTel(String tel) {
    this.tel = tel;
}

@Override 
public String toString() {  
  return this.getNombre() + " " + this.getEmail() + " " + this.getTel();
}

public int describeContents() {
    return 0;
}

public void writeToParcel(Parcel des, int flags) {

    des.writeString(getNombre());
    des.writeString(getEmail());
    des.writeString(getTel());

}

public static final Parcelable.Creator<Persona> creator = new Creator<Persona>() {

    public Persona createFromParcel(Parcel source) {

        return new Persona(source);
    }

    public Persona[] newArray(int size) {

        return new Persona[size];
    }

};

}

和我的活动代码（此活动检索一个意图，该意图带有我刚刚指定的类型的ArrayList）

public class Contacts extends Activity {

private ArrayAdapter<String> names;
private Intent intent;
private ArrayList<String>nameList;
private ListView list;

public Contacts() {
    intent = new Intent();
    nameList = new ArrayList<String>();
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.contacts);
    setIntent(getIntent());
    iterateContacts();
    names = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, getNameList());
    getList().setAdapter(getNames());
}

public void iterateContacts(){

    ArrayList<Persona> aux = GetIntent().getParcelableArrayListExtra("contactList");

    for(int i = 0; i<aux.size(); i++){

        String name = aux.get(i).getNombre();
        getNameList().add(name);
    }
}

public ArrayAdapter<String> getNames() {
    return names;
}

public void setNames(ArrayAdapter<String> names) {
    this.names = names;
}

public Intent GetIntent() {
    return intent;
}

public void setIntent(Intent intent) {
    this.intent = intent;
}

public ArrayList<String> getNameList() {
    return nameList;
}

public void setNameList(ArrayList<String> nameList) {
    this.nameList = nameList;
}

public ListView getList() {
    return list;
}

public void setList(ListView list) {
    this.list = list;
}

}

Answer 1

更改此：

public static final Parcelable.Creator<Persona> creator = new Creator<Persona>() {

对此：

public static final Parcelable.Creator<Persona> CREATOR = new Creator<Persona>() {

编辑：

而且看起来您的getList（）返回null，因为在onCreate的结尾之前未设置它，所以它没有设置：

getList().setAdapter(getNames());

没有看到您在初始化它，这可能是原因吗？
