Google 环氧树脂视图中的地图片段

Question

我目前正在探索来自 Airbnb

的新 MvRx 堆栈

现在我正在将 google 地图片段成功添加到 BottomNavigationView 中的 BaseMvRxFragment。

问题是 2. 我导航到 MapFragment 时我的应用程序崩溃了，我收到以下错误消息：

class MapFragment : BaseFragment() {


    private val mViewModel: ChatViewModel by fragmentViewModel()

    override fun epoxyController() = simpleController(mViewModel) {state ->


        mapView{
            id("map")
        }
    }

}

MapView.kt

        context: Context,
        attrs: AttributeSet? = null,

    init {
        // TODO: Fix crash on second view.
        inflate(context, R.layout.view_map, this)
    }
}

view_map.xml

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/map2"

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".ui.MainActivity" />

</FrameLayout>

感谢您的帮助！ <3

我在直接将地图片段添加到其他片段内时遇到问题，因此我建议使用 Framelayout 更改它并手动膨胀片段。
