Question

我正在创建一个对话框，其中包含x个用户可以选择的标签页。这种情况的独特之处在于我已经有一个TabHost用于我的活动。不知何故TabHost工作但我的新工作不是。我得到的错误是：

java.lang.IllegalArgumentException: No view found for id 0x7f0b005c (nl.raakict.android.spc:id/realtabcontent2) for fragment CreateCarrierTabFragment{211feed8 #2 id=0x7f0b005c Overig}

但我确信视图ID存在，因为这是我的XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <android.support.v4.app.FragmentTabHost
        android:id="@+id/tabhost2"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
            <TabWidget
                android:id="@+id/tabs2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@android:color/transparent" />
            <FrameLayout
                android:id="@+id/realtabcontent2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        </LinearLayout>
    </android.support.v4.app.FragmentTabHost>
</LinearLayout>

如果我在id：

上执行findviewbyid，这就是我在调试模式下看到的内容

tabhost test

                    CreateCarrierTabFragment.class, b);
        }
    }

}

请注意，如果我将其指向我其他TabHost的容器，它确实有效，但当然它会更改错误的容器。

Answer 1

我的观点并没有直接夸大活动，所以我使用了错误的FragmentManager，我必须使用的是getChildFragmentManager（）。

＆＃34;找不到id＆＃34;在TabHost设置中选择容器
