1.创建Parcelable对象

2.使用Parcelable对象

            // 初始化intent            mBase_intent = new Intent(this, MySelf_Bitmap_Activity.class);            // 初始化Parcelable对象            AddInfo info = new AddInfo(mView_myself_pop_edit[0].getText()                    .toString(), mView_myself_pop_edit[1].getText().toString(),                    mView_myself_pop_edit[2].getText().toString(),                    mView_myself_pop_edit[3].getText().toString(),                    mView_myself_pop_edit[4].getText().toString(),                    mView_myself_pop_edit[5].getText().toString());            // 添加Parcelable对象            mBase_intent.putExtra("myself_activity", info);            // 跳转            startActivity(mBase_intent);

3.提取Parcelable对象中的信息

        // 获得用户信息        mInfo = getIntent().getParcelableExtra("myself_activity_info");

4.Parcelable和Serializable性能对比：
