Android中的序列化 [英] Serialization in Android

问题描述

我正在尝试在 android 中序列化绘制和路径.当我将一个对象写入 Objectoutputstream 时，Notserializabale 异常被触发.我也在 serializabale 类中重写了 writeObject() 方法.

I am trying to Serialize paint and path in android. When I am write a object to Objectoutputstream the Notserializabale exception is fired. I am also overwite a writeObject() methods in serializabale class .

这是代码.

public class msgContainar implements Serializable 
{
/**
 * 
 */
public msgContainar()
{

}
private static final long serialVersionUID = 1L;
private Path pathStack;
private Paint paintStack;

public Path getPathStack() 
{
    return pathStack;
}

public void setPathStack(Path pathStack) 
{
    this.pathStack = pathStack;
}

public Paint getPaintStack() 
{
    return paintStack;
}
public void setPaintStack(Paint paintStack) 
{
    this.paintStack = paintStack;
}

private void writeObject(ObjectOutputStream out) throws IOException
{

    try
    {
    Paint p=new Paint();
    p.set(paintStack);

    Path path=new Path();

    path.addPath(pathStack);

    out.writeObject(path);
    out.writeObject(p);

    }catch (Exception e) 
    {
        Log.e("err",""+e);
    }

}

private void readObject(ObjectInputStream in) throws IOException{

    try{
    Paint p=new Paint();
    p=paintStack;

    Path path=new Path();

    path=pathStack;

    }catch (Exception e) {
        Log.e("err",""+e);
    }
}
}

推荐答案

Path 和 Paint 都没有实现 Serializable 接口.要解决此问题，您可以创建自己的自定义子类来扩展 Path 和 Paint 并实现 Serializable.

Neither Path nor Paint implements the Serializable interface. To work around this, you can create your own custom subclasses that extend Path and Paint and implement Serializable.
