Intent通过Serializable 传递List<object>

一、用Serializable

创建时：

Intent intent = new Intent();

List<User> list = new ArrayList<User>; intent.putExtra("自定义字符串(key)", list.toArray()); startActivity(intent); 前提是list中的User必须implements Serializable 接收时： Intent intent = this.getIntent(); Object[] cobjs = (Object[]) intent.getSerializableExtra("userList"); for (int i = 0; i < cobjs.length; i++) { User user = (User) cobjs[i];

userList.add(user);

二、涉及bundle

Intent intent = new Intent();

intent.setClass(Login.this, AnotherActivity.class);

Bundle bundle = new Bundle();

bundle.putSerializable("user",user);

intent.putExtras(bundle);

this.startActivity(intent);

接收端

Intent intent = this.getIntent();

User user = (User)inent.getSerializableExtra("user");
