Intent 传递对象

it2022-05-05  138

方法:

可以让这个要传递的对象所属类实现Serializable或者Parcelable接口,

然后利用onCreate函数中的Bundle参数作为载体,传递这个对象。

例如:

<span style="font-size:14px;color: rgb(75, 75, 75);"> @Override public void onItemClick(AdapterView<?> parent, View view, int position, long i) { User user= (User) Connect.getUser(position); Intent intent = new Intent(Activity1.this,Activity2.class); Bundle bundle = new Bundle(); bundle.putSerializable("USER", user); intent.putExtras(bundle); startActivity(intent); } } 在接收对象的地方: protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.detail); User </span><span style="color: rgb(75, 75, 75); font-size: 13px; font-family: georgia, verdana, Arial, helvetica, sans-seriff;">user</span><span style="color: rgb(75, 75, 75); font-size: 13px; font-family: georgia, verdana, Arial, helvetica, sans-seriff;">= (Item) getIntent().getSerializableExtra("user"); </span><span style="font-size:14px;color: rgb(75, 75, 75);"> //这里就得到user对象了,注意:必须确保user</span><span style="font-family: georgia, verdana, Arial, helvetica, sans-seriff; line-height: 19.5px;"><span style="font-size:12px;color:#666666;">类实现Serializable或者Parcelable接口</span></span><span style="font-size:14px;color: rgb(75, 75, 75);"> }</span>
