前言

android.os.Bundle 相信每一個Android 開發(fā)者都在使用，構(gòu)建bundle和獲取其中value時如果參數(shù)很多寫起來代碼很呆板材义，多次調(diào)用的話 key值容易寫錯酪碘，不易管理麸塞，AutoBundle的產(chǎn)生就是為了解決這些問題笨奠。AutoBundle采用動態(tài)代理的方式創(chuàng)建Bundle,采用編譯時注解的方式為屬性賦值管呵。

使用

1. 成員屬性 和 方法參數(shù) 注解解析
2. 創(chuàng)建單例
3. Activity中如何使用
4. 定義接口方法
5. 動態(tài)代理創(chuàng)建Bundle

1. 注解

In your class which has state from Bundle
(Activity, BroadcastReceiver, Service, Fragment or others),

@Box

在接口方法的參數(shù)上添加此注解 自動方法的值put進(jìn)bundle

@Unbox

在Activity梳毙、Fragment 或者任意類中的成員屬性添加此注解，自動獲取其值

@Required

如果添加此注解捐下，當(dāng)接口方法傳入或從Bundle中獲取的值為null時會crash

@BundleFlag

用于標(biāo)記創(chuàng)建Bundle的接口方法账锹，可以在回調(diào)函數(shù)中通過判斷此注解的value做二次修改替換等

2. 創(chuàng)建單例

 
 AutoBundle.builder().debug(true)//allow print debug message
                //check all create method before use
                .validateEagerly(true)
                .addOnBundleListener(new OnBundleListener() {
                    /**
                     * @param flag  flag is @BundFlag value
                     */
                    @Override
                    public void onBundling(int flag, String key, @Nullable Object value, boolean required) {
                        Log.e("print", "key:" + key + " flag:" + flag);
                    }

                    @Override
                    public void onCompleted(int flag, @NonNull Bundle bundle) {
                        Log.e("print", bundle.toString());
                        //replace or add
                        // for example
                        if (flag = xxx) {
                            bundle.put("xxx", xxx);
                        }
                    }
                })
                .installDefault();

3.Activity 中使用

public class MyActivity extends Activity {
    // field must not be private/protected.
    @Required
    @Unbox("loginName")
    String loginName;
    @Required
    @Unbox("password")
    String password;

    @Unbox("int")
    int intValue;

    @Unbox("string")
    String stringValue;

    @Unbox("intArray")
    int[] intArrayValue;

    @Unbox("stringArray")
    String[] stringArrayValue;

    @Unbox("parcelable")
    Parcelable ParcelableValue;

    @Unbox("parcelableArray")
    Parcelable[] parcelableArrayValue;

    @Unbox("sparseParcelableArray")
    SparseArray<? extends Parcelable> sparseParcelableArrayValue;

    @Unbox("stringArrayList")
    List<String> stringArrayListValue;

    @Unbox("parcelableArrayList")
    List<? extends Parcelable> parcelableArrayListValue;

    @Unbox("serializable")
    Serializable serializableValue;
}

如何給屬性自動賦值

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //auto bind the field from bundle
        AutoBundle.getDefault().bind(this);
    }

4.像Retrofit創(chuàng)建Call一樣創(chuàng)建Bundle

public interface BundleService {
    @BundleFlag(0)
    Bundle getLogin(@Required @Box("loginName") String loginName,
                    @Required @Box("password") String password);

    @BundleFlag(1)
    Bundle getInt(@Box("int") int value);

    @BundleFlag(2)
    Bundle getString(@Box("string") String value);

    @BundleFlag(3)
    Bundle getIntArray(@Box("intArray") int[] value);

    Bundle getStringArray(@Box("stringArray") String[] value);

    Bundle getParcelable(@Box("parcelable") Parcelable value);

    Bundle getParcelableArray(@Box("parcelableArray") Parcelable[] value);

    Bundle getSparseParcelableArray(@Box("sparseParcelableArray")
                                            SparseArray<? extends Parcelable> value);

    Bundle getStringArrayList(@Box("stringArrayList") ArrayList<String> value);

    Bundle getParcelableArrayList(@Box("parcelableArrayList") ArrayList<? extends Parcelable> value);

    Bundle getSerializable(@Box("serializable") Serializable value);
}

5.接口方法調(diào)用創(chuàng)建Bundle

//second step: you can crate Bundle like retrofit
   Bundle loginBundle = AutoBundle.getDefault()
                .create(BundleService.class)
                .getDefault("JackWharton","123456");

  Bundle intBundle = AutoBundle.getDefault()
                .create(BundleService.class)
                .getInt(1228);

In target class, Call binding method in onCreate.

• bind(Object target, Bundle bundle)
• bind(Activity target) (equals to bind(activity, activity.getIntent().getExtras()))
