吐槽:以前做iOS的，从没想过控制器传个对象又是Serializable又是Parcelable的，晕死😵。自己封装了, 可传递任意对象，不需要序列化。

一、调用示例：

1、传入

ObjectIntent.putObjectExtra(intent, "sdkParams", sdkParams);

2、 读取

ObjectIntent.getObjectExtra(getIntent(), "sdkParams");

3、清除

因为是全局的，防止内存泄漏，需要清理下。

• 最后一个getObjectExtra，clearAll传true

ObjectIntent.getObjectExtra(getIntent(), "sdkParams", true);

• 或者：

ObjectIntent.clear(getIntent());

二、ObjectIntent类

public class ObjectIntent extends Intent {

    private static String INTENT_ID = "INTENT-ID-TAIWAN-BELONGS-TO-CHINA";

    private static Map<String, Map<String, Object>> objectExtras = new ConcurrentHashMap<>();

    public static void putObjectExtra(Intent intent, String name, Object value) {
        String intentId = intent.getStringExtra(INTENT_ID);
        if (intentId == null || "".equals(intentId)) {
            intentId = uniqueUUID();
            //创建extra容器
            Map<String, Object> extras = new HashMap<>();
            objectExtras.put(intentId, extras);
            //在intent中记录容器id
            intent.putExtra(INTENT_ID, intentId);
        }
        Map<String, Object> intentContainer = objectExtras.get(intentId);
        intentContainer.put(name, value);
    }

    @SuppressWarnings(value = {"unchecked"})
    public static  <T> T getObjectExtra(Intent intent, String name) {
        try {
            Map<String, T> extras = getObjectExtras(intent);
            return extras.get(name);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    public static  <T> T getObjectExtra(Intent intent, String name, boolean clearAll) {
        try {
            Map<String, T> extras = getObjectExtras(intent);
            if (clearAll) {
                clear(intent);
            }
            return extras.get(name);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    public static void clear(Intent intent) {
        objectExtras.remove(intent.getStringExtra(INTENT_ID));
    }

    @SuppressWarnings(value = {"unchecked"})
    public static <T> Map<String, T> getObjectExtras(Intent intent) {
        try {
            String intentId = intent.getStringExtra(INTENT_ID);
            Map<String, T> extras = (Map<String, T>) objectExtras.get(intentId);
            return extras;
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    private static String uniqueUUID(){
        String uuid = null;
        while (uuid == null || objectExtras.containsKey(uuid)) {
            uuid = UUID.randomUUID().toString().replaceAll("-", "");
        }
        return uuid;
    }
}
