我正在尝试创建注册系统。我在第一个活动中声明了一次Profile的实例,然后我使用同一个实例传递给另一个活动。我已经将同一个对象传递了4次到其他活动,但是有一个给出了这个错误。
课堂电话:
btnNext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
newUser.setProfilePic(pic);
Intent itt = new Intent(Register20.this, Register30.class);
Bundle bd = new Bundle();
bd.putSerializable("newUser", newUser);
itt.putExtras(bd);
startActivity(itt);
Register20.this.finish();
}
});
收到的类:
public class Register30 extends AppCompatActivity {
Profile newUser = new Profile();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register30);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
newUser = (Profile)getIntent().getSerializableExtra("newUser");
}
}
我的自定义对象类(我没有把getter和setter放得太大):
public class Profile implements Serializable{
private String name;
private Integer age;
private String sex;
private String description;
private Calendar dateOfBirth;
private String password;
private String emailRegistration;
private int numberCellRegistration;
private ArrayList<Profile> friends = new ArrayList<>();
private ArrayList<Like> likes = new ArrayList<>();
private ImageView profilePic;
}
例外:

答案 0 :(得分:2)
或者:
从profilePic
或
Profile
将其更改为某些数据类型,该数据类型可以跨越流程边界传递并且不会太大(例如,资源ID),或
ImageView
无法跨进程边界传递,并且每个startActivity()
调用都会将Intent
从您的进程传递到核心操作系统进程(在这种情况下,返回到您的进程) )。相反,传递一些可以告诉您如何填充ImageView
Register30
中的其他Activity
的内容。
答案 1 :(得分:0)
引起:java.io.NotSerializableException: android.support.v7.widget.AppCompatImageView
ImageView不可序列化。相反,您应该在模型上传递包含给定图像的byteArray,并在onCreate
方法上重新创建它。
