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();
}

因此，在上面的代码中，我不知道为什么要在isSelected而不是isPaused上获得classCastExcpetion的原因。两者都具有相同的数据类型，并且以类似的方式使用。尝试搜索它仍然无法理解该问题。下面是它的日志。

而奇怪的是，我正在将其用于回收者视图。如果我在“回收者”视图中单击第一个项目，它将显示以下IllegalStateException；如果我单击任何其他项目，我将得到ClassCastException，如下所示

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，问题将消失。

Answer 2

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

我只是替换为上面的代码，它解决了这个问题。上课有个问题。
