Compilation error: Cannot find symbol FragmentBindingImpl with custom attributes

Question

我在其他地方有数据绑定，这是唯一给我这些问题的地方我没有匕首。如果我删除此视图中使用数据绑定的行，我不会收到任何错误，并且可以在我的设备上安装。我已经尝试了 rebuilding/restarting 和清除缓存以及删除构建文件的所有组合。我也试过禁用数据绑定并重新启用它。

这是我正在使用的布局文件 fragment_subscription.xml

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
  <data>

    <variable name="fragment" type="com.example.subscription.SubscriptionFragment"/>

    <variable name="week" type="com.android.billingclient.api.SkuDetails"/>
    <variable name="month" type="com.android.billingclient.api.SkuDetails"/>
    <variable name="year" type="com.android.billingclient.api.SkuDetails"/>

  </data>

<com.example.CustomButton
                android:id="@+id/week_subscription_button"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:padding="5dp"
                app:presetButtonPriceText="@{week.price}"
                app:presetButtonUnitText="@string/week_subscription_unit"
                app:presetButtonValueText="@string/week_subscription_value"/>

        <com.example.CustomButton
                android:id="@+id/month_subscription_button"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:padding="5dp"
                app:presetButtonPriceText="@{month.price}"
                app:presetButtonUnitText="@string/month_subscription_unit"
                app:presetButtonValueText="@string/month_subscription_value"/>

        <com.example.CustomButton
                android:id="@+id/year_subscription_button"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:padding="5dp"
                app:presetButtonPriceText="@{year.price}"
                app:presetButtonUnitText="@string/year_subscription_unit"
                app:presetButtonValueText="@string/year_subscription_value"/>

</layout>

这是我的自定义按钮特定视图属性

    <attr name="presetButtonUnitText" format="integer"/>
    <attr name="presetButtonPriceText" format="string"/>
    <attr name="presetButtonValueText" format="integer"/>

这是我在 SubscriptionFragment.kt

中创建视图的地方

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    return FragmentSubscriptionBinding.inflate(inflater, container, false).let {
        this.binding = it
        bind(skuDetailsList)
        it.root
    }
}

这是我绑定视图的地方

private fun bind(skuList: MutableList<SkuDetails>) {
    binding?.let {
        if (skuList.isNotEmpty()) {
            it.week = skuList[0]
            it.month = skuList[1]
            it.year = skuList[2]
            it.fragment = SubscriptionFragment@this
        }

    }
}

我尝试在我的应用程序中添加这些行 gradle.properties

android.databinding.enableV2 = true
android.enableExperimentalFeatureDatabinding = true

我已将这些添加到我的应用程序中 gradle

kapt 'com.android.databinding:compiler:3.1.4'
kapt {
    generateStubs = true
}
configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-annotations:23.1.1'
    }
}

这里我绑定了自定义属性，需要在我膨胀的自定义视图中设置自定义 getters/setters

编辑：

例子

public class ColorPicker extends View {
    private int color;

    public void setColor(int color) {
        this.color = color;
        invalidate();
    }

    public int getColor() {
        return color;
    }

//...
}

这是 xml 的样子

<com.example.myapp.ColorPicker
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:color="@{color}"/>
