我理解Enum是Serializable.因此,这样做是安全的.(selectedCountry是enum Country)

没有客户成员变量的原始枚举

public enum Country {
    Australia,
    Austria,
    UnitedState;
}

分段

@Override
public void onActivityCreated (Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    if (savedInstanceState != null) {
        selectedCountry = (Country)savedInstanceState.getSerializable(SELECTED_COUNTRY_KEY);
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putSerializable(SELECTED_COUNTRY_KEY, selectedCountry);
}

但是,如果我在自定义枚举类中有非可序列化成员,该怎么办？例如,

原始枚举客户成员变量

package org.yccheok;

import org.yccheok.R;

/**
 *
 * @author yccheok
 */
public enum Country {
    Australia(R.drawable.flag_au),
    Austria(R.drawable.flag_at),
    UnitedState(R.drawable.flag_us);

    Country(int icon) {
        this.icon = icon;
        nonSerializableClass = new NonSerializableClass(this.toString());
    }

    public int getIcon() {
        return icon;
    } …
