我不确定我的代码怎么了。我确保所有对象实现可序列化。我已经看过其他问题，但仍然找不到解决方案。有人可以帮我找出怎么了吗？谢谢你
这就是logcat中所说的

我真的被困在这里。我一遍又一遍地检查所有对象都可以序列化，但我仍然不确定问题是什么。谢谢！
在此方法中
public void onClick(View view) {
Intent intent = new Intent(appContext, AdminControls.class);
intent.putExtra("adminInterface", adminInterface);
appContext.startActivity(intent);
}
您通过自定义对象，因此请尝试此
public void onClick(View view) {
Bundle bundle = new Bundle();
bundle.putSerializable("adminInterface", adminInterface);
Intent intent = new Intent(appContext, AdminControls.class);
intent.putExtras(bundle);
appContext.startActivity(intent);
}
