Android: How to pass Parcelable object to intent and use getParcelable method of bundle?
提问by yital9
Why bundle has getParcelableArrayList, getParcelablemethods; but
Intenthas only putParcelableArrayListExtramethod?
Can I transmit only object<T>, not ArrayListof one element?
Then, what is getParcelablefor?
为什么 bundle 有getParcelableArrayList,getParcelable方法；但
Intent只有putParcelableArrayListExtra方法？我可以只传输object<T>，而不是ArrayList一种元素吗？那么，到底是getParcelable为了什么？

Intent provides bunch of overloading putExtra()methods.
Intent 提供了一堆重载putExtra()方法。
Suppose you have a class Foo implements Parcelable properly, to put it into Intent in an Activity:
假设您有一个类 Foo 正确实现了 Parcelable，将其放入 Activity 中的 Intent 中：
Intent intent = new Intent(getBaseContext(), NextActivity.class);
Foo foo = new Foo();
intent.putExtra("foo ", foo);
startActivity(intent);
To get it from intent in another activity:
从另一个活动的意图中获取它：
Foo foo = getIntent().getExtras().getParcelable("foo");
Hope this helps.
希望这可以帮助。

It is important to remember that your models must implement the Parcelableinterface, and the static CREATORmethod. This case is for the lists
请务必记住，您的模型必须实现Parcelable接口和静态CREATOR方法。此案例适用于列表
private static final String MODEL_LIST = "MODEL_LIST";
public MainFragment() {}
public static MainFragment newInstance(ArrayList<YourModel>
models) {
MainFragment fragment = new MainFragment();
Bundle args = new Bundle();
args.putParcelableArrayList(MODEL_LIST,models);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
ArrayList<YourModel> models = getArguments().getParcelableArrayList(MODEL_LIST);
}
}

First create Parcelable using Given Techniquethen
首先使用Given Technique创建 Parcelable然后
public static CreditCardDetail newInstance(CreditCardItemBO creditCardItem) {
CreditCardDetail fragment = new CreditCardDetail();
Bundle args = new Bundle();
args.putParcelable(CREDIT_KEY,creditCardItem);
fragment.setArguments(args);
return fragment;
}
And getting it like
并得到它喜欢
if(getArguments() != null)
{
creditCardItem = getArguments().getParcelable(CREDIT_KEY);
}
where
在哪里
public static final String CREDIT_KEY = "creditKey";
