IllegalAccessException - Serialization of object that inherits from non-serializable

问题

I getting android.widget.ImageView; IllegalAccessException when trying to deserialize my previously serialized object

        File presetFile = new File("pathToFile");

        FileInputStream fis = new FileInputStream(presetFile);      
        ObjectInputStream ois = new ObjectInputStream(fis);
        Preset preset = (Preset) ois.readObject();

I'm guessing that there is some restriction about ImageView, explanation below:

public class Preset implements Serializable {

    private Date dateOfCreation;
    private int bpm;
    private SoundSwitch[][] switches;

And finally SoundSwitch class header

public class SoundSwitch extends ImageView implements Serializable{
}

Is that because ImageView that I inherit from doesn't implement Serializable? Do I have to give up on deserializing such object?

回答1:

It is because the ImageView you are inheriting from is non-Serializable and doesn't have a public no-args constructor. Evidently it has a protected or package-access or private one.
