}

我正在尝试使用

传递它

Intent viewProfile = new Intent(getApplicationContext(), ScreenMemberProfile.class);       
viewProfile.putExtra("memberList", memberList.get(positon));

然而问题是位图不可用，可能我知道任何其他替代

Answer 1

传递Bitmap到Activities是可能的，但内存非常昂贵。您应该将其保存在外部存储器（缓存/ SD卡）上并将其路径（包含在Bitmap对象中）传递给下一个Serializable，而不是传递Activity对象。活动将该路径解码为Bitmap并相应地使用。

public class MemberDetailsObject implements Serializable {
    // other member ... 
    String memberImagePath;
    // rest of the class ...
}

Answer 2

Bitmap ist Parcelable，因此您可以将其置于Intent中。

Answer 3

这是将位图发送到其他活动的最佳方式，因为位图不可用，但是实现
