Serializable（接口）

通過intent?的bundle傳遞參數

Bundle?bundle?=?new?Bundle();
?????bundle.putSerializable(IntentKeys.IMG_ARR_ENVIR_IMG,?mArrListEnvir_img);
?????intent.putExtras(bundle);

mListEnvir?=?(ArrayList<EnvirImg>)?(bundle
????.getSerializable(IntentKeys.IMG_ARR_ENVIR_IMG));

?

Parcelable（接口）

通過intent?的bundle傳遞參數

Bundle?bundle?=?new?Bundle();
bundle.putParcelable(IntentKeys.IMG_ARR_ENVIR_IMG,?mArrListEnvir_img);
intent.putExtras(bundle);

Parcelable比Serializable效率高

parcelable也不適合傳輸大量圖片數據

android.os.TransactionTooLargeException?不適合傳大量數據尤其bitmap?intent跳轉的時候無縫傳遞數據pacicl
導致原因是：Binder傳輸的數據太大
如果Binder的參數或返回值太大，不適合的事務緩沖區，然后調用將失敗，并將被拋出TransactionTooLargeException。
解決方法：
不要將大量數據傳入Binder
