java - Parcelable 写入可序列化对象 SparseArray 时遇到 IOException

Question

所以我想在 Bundle 中发送一个 SparseArray，但由于它不能，我创建了一个类来将 SparseArray 变成可序列化对象，但现在当我运行我的应用程序时，它会给出此错误输出。

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.awemobi.legominifigures.DataHelper)

给出这个问题的类(class)是下一个:

public class DataHelper implements Serializable {
private SparseArray<int[]> data;

public DataHelper(SparseArray<int[]> data)
{
    this.data = data;
}

public SparseArray<int[]> getArray()
{
    return  data;
}

}

我认为这可能是因为 int[]，我什至创建了另一个类 Positions 来使 int[] 可序列化，但问题仍然存在。我可以尝试做更多什么？我无法准确追踪错误的原因。

这是完整的输出:

Answer 1

尝试将 SparseArray 变量“数据”声明为 transient 变量，如下所示，

private transient SparseArray<int[]> data;
