Android单选按钮双向数据绑定

我试图用两种方式将模型的布尔值绑定到RadioButton。 但是，代码不会编译。我收到以下错误消息：

错误：（41，21）错误：已定义变量receiveDataContainer 在方法onChange（）中

错误：（45，59）错误：不兼容的类型：无法转换布尔值 接收数据容器

错误：（46，17）错误：不兼容的类型：ReceiveDataContainer无法 转换为布尔值

我的班级：

public class ReceiveDataContainer extends BaseObservable {
    private boolean isShopReceiveMethodChosen;

    @Bindable
    public boolean isShopReceiveMethodChosen() {
        return isShopReceiveMethodChosen;
    }

    public void setShopReceiveMethodChosen(boolean isShopReceiveMethodChosen) {
        this.isShopReceiveMethodChosen = isShopReceiveMethodChosen;
        notifyPropertyChanged(BR.shopReceiveMethodChosen);
    }
}

XML:

值得一提的是，当我删除“=”符号时，代码会编译

请帮助我…

好的，我通过将类的名称从ReceiveDataContainer更改为ReceiveContainer解决了这个问题。我不知道为什么会这样，但它确实
