当尝试使用createNewLayerBuilder()添加新的CyborgController时,应用程序崩溃

cyborg android

这就是我在应用课程中所做的:

@Override
public void onCreate() {
    super.onCreate();
    CyborgBuilder.startCyborg(new CyborgConfiguration(this, R.layout.cyborgview__auto_reply, BasicModulePack.class));
}

这就是cyborgview\uu auto\u的回复方式。xml看起来像:

<?xml version="1.0" encoding="utf-8"?>
<com.nu.art.cyborg.core.CyborgView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cyborg="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
cyborg:controller="com.hedshafran.autoreply.controllers.Controller_PermissionScreen"
cyborg:tag="Controller_Permission"/>

createNewLayerBuilder().setControllerType(Controller_MainScreen.class).setLayoutId(R.layout.controller__main_screen).build();

导致崩溃的原因如下:

你的应使用将包含Controller\u PermissionScreen的CyborgStackConroller,如下所示:

<?xml version="1.0" encoding="utf-8"?>
<com.nu.art.cyborg.core.CyborgView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:cyborg="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/CV_RootStack"
    cyborg:controller="com.nu.art.cyborg.core.CyborgStackController"
    cyborg:rootController="com.hedshafran.autoreply.controllers.Controller_PermissionScreen"

    cyborg:rootTag="Controller_Permission"
    cyborg:tag="RootStack"
    />

如果调用此方法的控制器在堆栈中,则返回api。否则,请使用 getControllerById(R.id.CV_RootStack) 并创建一个新的图层生成器。
