我试图在片段的onCreate方法中解组parcelable 

 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Bundle args = getArguments();
    if (args != null) {
        mArticle = args.getParcelable(Consts.ARTICLE_KEY);
    }
}

然后不是每次我都遇到以下状态的崩溃：

Caused by: java.lang.RuntimeException: Parcel android.os.Parcel@3348215c: Unmarshalling unknown type code 7602280 at offset 4068
   at android.os.Parcel.readValue(Parcel.java:2222)

   at android.support.v7.app.AppCompatActivity.onCreate(AppCompatActivity.java:58)

该异常的原因是什么以及我如何解决它。 谢谢。

答案 0 :(得分：0)

您的mAddressLatitude和mAddressLongitude类型为double，并且您将它们解组为float类型：

mAddressLatitude = in.readFloat();
mAddressLongitude = in.readFloat();

如果你把它写成双重应该是：

mAddressLatitude = in.readDouble();
mAddressLongitude = in.readDouble();
