Android自定义视图:如何通过LiveData和数据绑定更新自定义枚举属性

public class CustomView extends View {
    private MutableLiveData<EnumType> enumProperty = new MutableLiveData<>();

    // 构造函数和其他方法

    public LiveData<EnumType> getEnumProperty() {
        return enumProperty;
    }

    public void setEnumProperty(EnumType value) {
        enumProperty.setValue(value);
    }
}

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable
            name="viewModel"
            type="com.example.ViewModel" />
    </data>

    <com.example.CustomView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:enumProperty="@{viewModel.enumProperty}" />
</layout>

public class ViewModel extends ViewModel {
    private MutableLiveData<EnumType> enumProperty = new MutableLiveData<>();

    // 构造函数和其他方法

    public LiveData<EnumType> getEnumProperty() {
        return enumProperty;
    }

    public void setEnumProperty(EnumType value) {
        enumProperty.setValue(value);
    }
}
