我试图以两种方式将我的模型的布尔值绑定到 RadioButton。但是，代码无法编译。我有以下错误消息：

错误：(41, 21) 错误：变量 receiveDataContainer 已在方法 onChange() 中定义

错误：(45, 59) 错误：不兼容的类型：布尔值无法转换为 ReceiveDataContainer

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

我的课：

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:

<RadioGroup
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginEnd="16dp"
            android:layout_marginStart="16dp"
            android:layout_marginTop="16dp"
            android:orientation="vertical"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/inputLayoutPhoneNumber">

            <RadioButton
                android:id="@+id/radio_receive_in_store"
                android:text="@string/radio_button_receive_in_store"
                android:checked="@={receiveDataContainer.shopReceiveMethodChosen}"
                style="@style/CartReceptionRadioButton" />

            <RadioButton
                android:id="@+id/radio_send_to_home"
                android:text="@string/radio_button_send_to_home"
                style="@style/CartReceptionRadioButton" />

        </RadioGroup>

并且生成的代码标记为无效：

// Inverse Binding Event Handlers
private android.databinding.InverseBindingListener radioReceiveInStorea = new android.databinding.InverseBindingListener() {
    @Override
    public void onChange() {
        // Inverse of receiveDataContainer.shopReceiveMethodChosen
        //         is receiveDataContainer.setShopReceiveMethodChosen((boolean) callbackArg_0)
        boolean callbackArg_0 = radioReceiveInStore.isChecked();
        // localize variables for thread safety
        // receiveDataContainer.shopReceiveMethodChosen
        boolean shopReceiveMethodCho = false;
        // receiveDataContainer
        com.abastra.home_cook.catalogue.data.models.ReceiveDataContainer receiveDataContainer = mReceiveDataContaine;
        // receiveDataContainer != null
        boolean receiveDataContainer = false;



        receiveDataContainer = (receiveDataContainer) != (null);
        if (receiveDataContainer) {




            receiveDataContainer.setShopReceiveMethodChosen((boolean) (callbackArg_0));
        }
    }
};

值得一提的是，当我删除“=”符号时，代码会编译。

请帮我...

好的，我通过将我的类的名称从 ReceiveDataContainer 更改为 ReceiveContainer 来解决它。我不知道为什么会这样，但它确实......
