我收到此错误：

运行时：

holder.butArea.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent myIntent = new Intent(v.getContext(), game.LevelActivity.class);
                myIntent.putExtra("switchlevel", LevelSwitchCase.getLevel(currentLevel, (pos+1),mContext));
                myIntent.putExtra("level",currentLevel);
                myIntent.putExtra("area", (pos+1));

                v.getContext().startActivity(myIntent);

            }
        });

game.level 正在实现可序列化并在启动意图时收到错误 (v.getContext().startActivity(myIntent);)

level 和 area 只是整数，而 switchlevel 是我得到的一个级别（实现 Serializable）

上下文不可序列化。为了解决这个错误，我声明了这样的上下文（变量不序列化）：

  public transient Context mContext;

或者你可以实现 Parceable。

如果你的关卡类有非原始成员，它们也应该实现可序列化。

对于那些在接口内使用上下文或其他不可序列化对象的人。只需将其作为参数传递给方法，例如：

public interface OnActionInterface {
    void onPositiveButtonClicked(Activity activity);
    void onNegativeButtonClicked(Activity activity);
}

然后创建一个独立的类，如：

public class SomeClass implements OnActionInterface, Serializable {
    private String action;

    public SomeClass(String action) {
        this.action = action;
    }

    @Override
    public void onPositiveButtonClicked(Activity activity) {
        Intent intent = new Intent(action);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        activity.startActivity(intent);
    }

    @Override
    public void onNegativeButtonClicked(Activity activity) {
        activity.finish();
    }
}

之后，您可以在意图中使用此类的对象。
