android升级至sdk 27黑屏无错误

我将我的应用程序从SDK 22升级到27，在我使用自定义视图（a）的每个视图上，屏幕都会变黑。没有错误，只有黑色。 这是一款有瓷砖的棋盘游戏，你可以四处移动，所以在这个视图中有很多可绘制的东西。 因此，我的观点如下：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    style="@style/AppTheme">

    <my.custom.app.view.BoardView
        android:id="@+id/game_board_view"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"/>
</LinearLayout>

没有错误信息，我迷路了。。。为什么它不渲染视图？这可能是内存问题吗？
