在 isSelected 处获取 ClassCastException 或 IllegalStateException

Question

@SerializedName("profileName")
private String profileName;
@SerializedName("paused")
private boolean isPaused;
@SerializedName("numberOfDevices")
private int numberOfDevices;

private boolean isSelected;

public Profile(String profileName, Boolean isPaused, int numberOfDevices) {
    this.profileName = profileName;
    this.isPaused = isPaused;
    this.numberOfDevices = numberOfDevices;
}

protected Profile(Parcel in) {
    profileName = in.readString();
    isPaused = (boolean) in.readValue(boolean.class.getClassLoader());
    isSelected = (boolean) in.readValue(boolean.class.getClassLoader());
    numberOfDevices = in.readInt();
}

So in the above code dont know the reason why I am getting classCastExcpetion on isSelected and not in isPaused. Both are having same datatypes and used in a similar way. Tried searching for it still not able to understand the issue. Below are the logs for it.

And the weird part is I am using that for a recycler view. If I click on 1st item in recycler view it gives the below IllegalStateException and if I click on any other item I am getting ClassCastException as below

java.lang.Short cannot be cast to java.lang.Boolean

Answer 1

您没有 isSelected 的 @SerializedName。它将读取 numberOfDevices 的值并分配给 isSelected 并导致异常。为 isSelected 添加 SerializedName，问题就会消失。

Answer 2

 protected Profile(Parcel in) {
    profileName = in.readString();
    isPaused = in.readByte() != 0;
    numberOfDevices = in.readInt();
    isSelected = in.readByte() != 0;
}

我只是用上面的代码替换它就解决了问题。以上 class 中存在一些问题。
